dynamic-openapi-cli

An OpenAPI spec becomes a CLI.
The CLI becomes a single-file executable.
The executable updates itself.

Point it at a spec — every operation is a subcommand.
Freeze it to a bash shim — commit it, ship it, install it with one command.
Run update when the API evolves — the shim rewrites itself in place.

30-second demo

# 1. any OpenAPI spec becomes a CLI — no install needed
$ npx dynamic-openapi-cli -s https://petstore3.swagger.io/api/v3/openapi.json --help
Petstore - OpenAPI 3.0

Usage: dynamic-openapi-cli [command] [options]

Commands:
  list-pets       List all pets
  get-pet-by-id   Find pet by ID
  create-pet      Add a new pet to the store
  update-pet      Update an existing pet
  delete-pet      Deletes a pet
  ...

# 2. call an operation — path params are positional, query params are options
$ npx dynamic-openapi-cli -s ./petstore.yml get-pet-by-id 42
{
  "id": 42,
  "name": "Rex",
  "status": "available"
}

# 3. freeze the spec into a single-file bash executable
$ dynamic-openapi-cli bundle -s ./petstore.yml --name petstore --out ./petstore
bundled "petstore" v1.0.0 → ./petstore (7.3 KB, 18 operations)

# 4. install it globally
$ ./petstore install
petstore install: symlinked ~/.local/bin/petstore → ./petstore

# 5. use it anywhere
$ petstore list-pets --status=available --limit=5

# 6. later, when the API evolves on the server
$ petstore update
petstore update: spec changed (md5 bb864f70 → e5789514), … 1.0.0 → 1.1.0.

That's the whole product.

Quick start

# no install — just run it
npx dynamic-openapi-cli -s ./spec.yaml <command>

# or install globally once
npm install -g dynamic-openapi-cli
dynamic-openapi-cli -s ./spec.yaml <command>

Three ways to use it, depending on what you need:

Mode 1 — ad-hoc (dev, scripts, CI)

dynamic-openapi-cli -s https://api.example.com/openapi.json \
  list-pets --limit=20 --status=available

Reads the spec fresh every run. Good for scripting, first exploration, or CI jobs where the spec is always fetched from source.

Mode 2 — bundled (distribute a CLI)

dynamic-openapi-cli bundle \
  -s ./openapi.yml \
  --name my-api \
  --out ./my-api

chmod +x ./my-api
./my-api install
my-api list-pets --limit=20

Packages the spec into a single-file bash executable. Commit it, symlink it, publish it to npm. Consumer only needs Node.js + npx (no install of dynamic-openapi-cli required — shim falls back to npx --yes).

Mode 3 — programmatic (TypeScript)

import { loadSpec, resolveSpec, buildCli, runCli } from 'dynamic-openapi-cli'

const spec = await resolveSpec(await loadSpec('./openapi.yml'))
const cli = buildCli({
  spec,
  name: 'my-api',
  authConfig: { bearerToken: process.env.API_TOKEN! },
})

await runCli(cli, process.argv.slice(2))

Use the internals directly when you need a richer integration — custom auth, custom output formatting, or embedding the CLI in a larger tool.

Why this, and not curl / httpie / postman-cli?

# curl — you write the URL, the headers, the query string, the auth, every time
curl -H "Authorization: Bearer $TOKEN" \
     "https://api.example.com/pets?limit=20&status=available"

# httpie — nicer, but still stringly-typed and unaware of the spec
http GET api.example.com/pets Authorization:"Bearer $TOKEN" limit==20 status==available

# dynamic-openapi-cli — the spec knows everything already
petstore-cli list-pets --limit=20 --status=available

The CLI reads your OpenAPI spec and is the documentation: --help on any operation shows the path, method, parameters with their types and enum values, and where the request body fits.

             Pretty-printed JSON /
             Raw body / -o file

One library, three entry points: the dynamic CLI for ad-hoc runs, the bundle command for packaging, and the programmatic TypeScript API for deeper integrations. All three share the same parser, HTTP client, and auth layer.

Command mapping

OpenAPI	Becomes in the CLI
operationId: listPets	Command list-pets (kebab-cased)
GET /pets/{petId} (no operationId)	Command derived from method + path
summary / description	Command description shown in --help
Path params (in URL order)	Required positional args
Query / header / cookie params	--options with type coercion
Parameter default	Option default shown in --help
Parameter enum: [a, b, c]	choices — rejected values fail with error
requestBody	--body '<json>' and --body-file <path>
deprecated: true	[deprecated] prefix in description

Example spec → CLI:

# openapi.yml
paths:
  /pets/{petId}:
    get:
      operationId: getPetById
      summary: Fetch a pet by its id
      parameters:
        - { name: petId, in: path, required: true, schema: { type: integer } }
        - { name: include, in: query, schema: { type: string, enum: [owner, photos, history] } }

$ my-cli get-pet-by-id --help
my-cli get-pet-by-id
Fetch a pet by its id

Usage: my-cli get-pet-by-id <petId> [options]

Options:
  --include <string>     (choices: owner, photos, history)

$ my-cli get-pet-by-id 42 --include=photos

Response handling

Response body	Default behavior	With --raw	With -o file
application/json	Pretty-printed to stdout	Written verbatim	Saved as bytes
Other text (text/*, XML, YAML)	Written verbatim	Written verbatim	Saved as bytes
Binary ≤ 256 KB	Inline JSON envelope with base64 data	same	Saved as raw bytes
Binary > 256 KB	Error: -o <file> required	same	Saved as raw bytes

Every subcommand gets four global options for free:

  -o, --output <file>       Save response body to file
      --raw                 Don't pretty-print JSON
  -V, --verbose             Print HTTP status + headers to stderr
      --dry-run             Print the equivalent curl command instead of firing the request

--dry-run: preview requests as curl

Every CLI or bundled shim can print the resolved request as a curl command — URL, headers (including the ones resolved by auth), and body — without firing it:

$ petstore list-pets --dry-run --limit=5 --status=available
curl -X GET 'https://api.example.com/pets?limit=5&status=available' \
  -H 'accept: application/json' \
  -H 'authorization: Bearer sk-…'

$ petstore create-pet --dry-run --body='{"name":"rex"}'
curl -X POST 'https://api.example.com/pets' \
  -H 'accept: application/json' \
  -H 'content-type: application/json' \
  --data '{"name":"rex"}'

Useful for copy-pasting into bug reports, sharing a reproducer, or feeding another tool. Works with every body kind: JSON, URL-encoded, multipart, and binary.

Piping bodies: --body=-, --body-file, and @path

Source	How
Inline literal	--body='{"name":"rex"}'
From stdin	echo '{…}' | my-cli create-pet --body=-
From a file	my-cli create-pet --body-file=./new-pet.json
Multipart file upload	--body='{"file":"@/path/to/a.pdf","kind":"invoice"}'
Binary upload	--body='@/path/to/blob.bin' (for application/octet-stream bodies)

@path works anywhere a body value can be a file reference — multipart field values, binary request bodies. Prefix with @@ to escape (a literal string starting with @). The CLI reads the file at request time and streams the bytes into the multipart envelope or the request body.

Shell completions

cli-args-parser generates completions for the three major shells. Both the dynamic CLI and bundled shims expose them as completion <shell>:

# Bash
dynamic-openapi-cli -s ./spec.yaml completion bash >> ~/.bashrc

# Zsh — drop into a dir on your $fpath, or eval it at shell startup
petstore completion zsh > "${fpath[1]}/_petstore"

# Fish
petstore completion fish > ~/.config/fish/completions/petstore.fish

Completions cover top-level commands and per-command options. Bundled CLIs pass through transparently, so my-api completion bash works on any shim.

Exit codes:

Code	When
0	Success (HTTP 2xx/3xx)
1	Network error, 5xx, or unexpected failure
2	Validation error or HTTP 4xx

Bundle — the killer feature

One command turns any spec into a single-file bash executable that runs anywhere node runs.

dynamic-openapi-cli bundle \
  -s ./openapi.yml \
  --name petstore \
  --out ./petstore
# → bundled "petstore" v1.0.0 → ./petstore (7.3 KB, 18 operations)

What's inside the shim?

• Full OpenAPI spec, base64-encoded and dereferenced ($refs resolved).
• MD5 hash of the spec, baked into the file for change detection.
• Original source (URL or absolute path), so update knows where to re-fetch.
• Runtime delegation to dynamic-openapi-cli (global binary → npx --yes fallback → friendly error).

$ head -15 ./petstore
#!/usr/bin/env bash
# Generated by dynamic-openapi-cli
# CLI name:    petstore
# Version:     1.0.0

# Spec MD5:    bb864f7025e1408ccdc00f11f5c0e8bb
# Spec:        embedded as base64-encoded JSON (dereferenced OpenAPI v3)

CLI_NAME='petstore'

SPEC_MD5='bb864f7025e1408ccdc00f11f5c0e8bb'
SPEC_B64='eyJvcGVuYXBpIjoiMy4wLjMi...'

Subcommands every shim ships with

Subcommand	What it does
<any-operation>	Call the mapped API operation
--help	Print help (top-level or per-command)
--show-spec	Decode and print the embedded spec as JSON
--spec-md5	Print just the MD5 hash (scriptable)
--spec <url|file>	Override the embedded spec at runtime (dev)
update	Re-fetch the original spec and rewrite this file
install	Symlink/copy into a PATH directory
uninstall	Remove a previous install

Self-update

The shim remembers where the spec came from. When the API evolves, update re-fetches, regenerates, and rewrites the file in place:

$ petstore --help                     # petstore 1.0.0
$ petstore --spec-md5
bb864f7025e1408ccdc00f11f5c0e8bb

# ... the API ships v1.1.0 on the server ...

$ petstore update
petstore update: fetching https://petstore3.swagger.io/api/v3/openapi.json ...
bundled "petstore" v1.1.0 → /tmp/petstore.update.12345 (7.4 KB, 19 operations)
petstore update: spec changed (md5 bb864f70 → a12c9e31), ./petstore 1.0.0 → 1.1.0.

$ petstore --help                     # petstore 1.1.0 — new operation visible

The CLI version tracks the spec version. It's a snapshot of your API at a point in time, not a separate SemVer of the CLI tool. Override only if you actually need decoupled versioning:

petstore update                            # default: follow new spec.info.version
petstore update --app-version=2.0.0       # explicit override
petstore update --spec ./dev-spec.yml     # use a different source this time

Idempotent: running update when nothing changed is safe and prints spec unchanged (md5 …). Perfect for a cron job or a CI step.

# Example: daily spec check
0 3 * * * /usr/local/bin/petstore update >> /var/log/petstore-update.log 2>&1

If the bundle was built from an inline spec (raw JSON/YAML string, not a file or URL), update fails loudly — there's nothing to re-fetch. Re-run dynamic-openapi-cli bundle manually in that case.

Making the bundled CLI globally available

Three options, from "one command" to "npm ecosystem":

1. Built-in install (recommended)

./petstore install                                # symlinks to ~/.local/bin/petstore
./petstore install --dir /usr/local/bin           # another directory
./petstore install --dir /usr/local/bin --copy    # copy instead of symlink
./petstore install --force                        # overwrite an existing install
./petstore uninstall                              # remove it

Defaults to $XDG_BIN_HOME or $HOME/.local/bin — no sudo needed. If the target directory isn't on your PATH, the command prints the exact line to add to your shell rc:

petstore install: warning — ~/.local/bin is not on your PATH yet.
       Add this line to your shell rc (~/.bashrc, ~/.zshrc, or equivalent):

         export PATH="$HOME/.local/bin:$PATH"

Why symlink by default: running update in the original location transparently refreshes the globally-linked binary. Copy mode (--copy) is useful when you want the installed version frozen against further updates.

2. Manual move/symlink

Classic UNIX:

mv ./petstore /usr/local/bin/
# or
ln -s "$PWD/petstore" /usr/local/bin/petstore

3. Publish as an npm package

Wrap the shim in a tiny package.json and publish — users then install with npm install -g <your-cli>:

{
  "name": "petstore-cli",
  "version": "1.0.0",
  "bin": { "petstore-cli": "./petstore" },
  "files": ["petstore"]
}

npm publish
# consumers:
npm install -g petstore-cli
petstore-cli list-pets

Good fit when you already have CI/CD publishing to npm and want your team's CLI to follow the same distribution path as other internal tools. Pair with a bundle step in CI to keep the shim up to date with the latest spec.

Authentication

Same variables and resolution order as dynamic-openapi-mcp — programmatic config → per-scheme env var → global env var.

Scheme	Env var	Programmatic
Bearer	OPENAPI_AUTH_TOKEN or OPENAPI_AUTH_<SCHEME>_TOKEN	auth.bearerToken
API Key (header/query/cookie)	OPENAPI_API_KEY or OPENAPI_AUTH_<SCHEME>_KEY	auth.apiKey
Basic	OPENAPI_AUTH_<SCHEME>_TOKEN as user:pass	auth.basicAuth
OAuth2 client credentials	—	auth.oauth2 (auto-refresh)
OAuth2 authorization code	OPENAPI_OAUTH2_CLIENT_ID (+ OPENAPI_OAUTH2_SCOPES)	new OAuth2AuthCodeFlow({…})
Custom token exchange	—	auth.tokenExchange (auto-refresh)
Fully custom	—	auth.custom (callback)

Per-scheme env vars are derived from the securitySchemes name in your spec:

components:
  securitySchemes:
    bearerAuth:
      type: http
      scheme: bearer

maps to OPENAPI_AUTH_BEARERAUTH_TOKEN. Useful when a single CLI needs to talk to multiple auth realms.

# one-liner
OPENAPI_AUTH_TOKEN=sk-123 petstore list-pets

# typical dev workflow
export OPENAPI_AUTH_TOKEN=$(vault read -field=token secret/petstore)
petstore list-pets
petstore create-pet --body-file=new-pet.json

OAuth2 authorization code (browser login)

When the spec declares an OAuth2 authorizationCode flow and OPENAPI_OAUTH2_CLIENT_ID is present, the CLI triggers a browser-based login on the first request — PKCE + loopback server on 127.0.0.1:7999 — and caches the token under $XDG_DATA_HOME/dynamic-openapi-cli/tokens/. Subsequent calls reuse the cached token and refresh it transparently when it expires.

export OPENAPI_OAUTH2_CLIENT_ID=cli-public
export OPENAPI_OAUTH2_SCOPES="read:pets write:pets"
# optional, defaults shown:
# export OPENAPI_OAUTH2_PORT=7999
# export OPENAPI_OAUTH2_REDIRECT_URI=http://127.0.0.1:7999/callback
# export OPENAPI_OAUTH2_CLIENT_SECRET=...   # confidential clients only

# Explicit login / logout (spec required):
dynamic-openapi-cli -s ./spec.yaml login         # opens a browser, writes the cached token
dynamic-openapi-cli -s ./spec.yaml logout        # removes the cached token

# Or just run any operation — login triggers automatically on the first call.
petstore list-pets

Per-scheme env vars (derived from the scheme name in the spec, same casing rules as other schemes) take precedence: OPENAPI_AUTH_<SCHEME>_CLIENT_ID, OPENAPI_AUTH_<SCHEME>_SCOPES, OPENAPI_AUTH_<SCHEME>_PORT, OPENAPI_AUTH_<SCHEME>_REDIRECT_URI, OPENAPI_AUTH_<SCHEME>_CLIENT_SECRET.

Redirect URI must match what the provider has registered — override via OPENAPI_OAUTH2_REDIRECT_URI (or per-scheme) when using hosts other than 127.0.0.1:<port>/callback. The token file has mode 0600.

CLI reference

dynamic-openapi-cli [bootstrap flags] <command> [...args]

Bootstrap flags (before the command):
  -s, --source <url|file>       OpenAPI spec URL, file path, or inline JSON/YAML
      --spec <url|file>         Alias for --source (used by bundled shims)
  -b, --base-url <url>          Override the base URL from the spec
      --server-index <n>        Pick the Nth server entry from the spec (default: 0)
      --name <string>           Display name in help (for bundled CLIs)
      --app-version <string>    Display version in help (for bundled CLIs)
      --include-tag <name>      Only expose operations with this tag (repeatable, comma-separated)

      --include-operation <id>  Only expose these operationIds (repeatable, comma-separated)
      --exclude-operation <id>  Hide these operationIds (repeatable, comma-separated)
      --self-version            Print dynamic-openapi-cli's own version
  -h, --help                    Show help (global or per-command)

Global options (after the command):
  -o, --output <file>           Save response body to file
      --raw                     Skip pretty-printing
  -V, --verbose                 Print HTTP status + headers to stderr
      --dry-run                 Print the equivalent curl command instead of firing the request

Request body (for operations that accept one):
      --body <string|->         Inline body; pass "-" to read from stdin
      --body-file <path>        Read body from a file
                                Multipart / binary bodies accept "@path" for file uploads.

Subcommands (spec required):
  completion <shell>            Print a shell completion script (bash, zsh, fish)

Built-in subcommands (no spec required):
  bundle                        Package a spec into a standalone bash CLI
                                (run "bundle --help" for details)

Environment

Variable	Purpose
OPENAPI_SOURCE	Spec URL or file path (alternative to -s)
OPENAPI_BASE_URL	Override the base URL
OPENAPI_SERVER_INDEX	Select server entry (0-based)
OPENAPI_AUTH_TOKEN	Global bearer token
OPENAPI_API_KEY	Global API key
OPENAPI_AUTH_<SCHEME>_TOKEN	Per-scheme bearer/basic token
OPENAPI_AUTH_<SCHEME>_KEY	Per-scheme API key
OPENAPI_OAUTH2_CLIENT_ID	OAuth2 authorization-code client id (activates browser login)
OPENAPI_OAUTH2_CLIENT_SECRET	OAuth2 client secret (confidential clients only)
OPENAPI_OAUTH2_SCOPES	Space- or comma-separated scope list (overrides spec)
OPENAPI_OAUTH2_PORT	Loopback redirect port (default 7999)
OPENAPI_OAUTH2_REDIRECT_URI	Full redirect URI override

Filtering operations

Not every endpoint should show up as a subcommand. Two ways to trim:

Flags (and programmatic filters)

# read-only CLI: only the `pets` tag passes
dynamic-openapi-cli -s ./spec.yaml --include-tag pets list-pets

# hide admin commands
dynamic-openapi-cli -s ./spec.yaml --exclude-tag admin

# allowlist a specific set of operationIds
dynamic-openapi-cli -s ./spec.yaml --include-operation listPets,getPetById

# everything under `pets`, minus one destructive op
dynamic-openapi-cli -s ./spec.yaml --include-tag pets --exclude-operation deletePet

Programmatic equivalent via buildCli:

const cli = buildCli({
  spec,
  filters: {
    tags: { include: ['pets'], exclude: ['admin'] },
    operations: { include: ['healthCheck'], exclude: ['deletePet'] },
  },
})

Precedence (first match wins): x-hidden → operations.exclude → operations.include → tags.exclude → includes as allowlist. operations.include escapes a matching tags.exclude, but operations.exclude wins over everything except x-hidden.

x-hidden vendor extension

Hide an endpoint at the spec level — no flags required, applies to every consumer:

paths:
  /admin/reset:
    post:
      operationId: adminReset
      x-hidden: true        # always removed, no matter what filter flags say

Use it for endpoints that appear in the public spec but should never become CLI subcommands, MCP tools, or skill operations.

Programmatic API

import {
  loadSpec,
  resolveSpec,
  buildCli,
  runCli,
  executeOperation,
  resolveAuth,
  resolveBaseUrl,
} from 'dynamic-openapi-cli'

Build a full CLI from a spec

import { loadSpec, resolveSpec, buildCli, runCli } from 'dynamic-openapi-cli'

const spec = await resolveSpec(await loadSpec('./openapi.yml'))

const cli = buildCli({
  spec,
  name: 'my-api',
  version: '2.0.0',
  authConfig: { bearerToken: process.env.MY_API_TOKEN! },
  defaultHeaders: { 'X-Client-Id': 'my-team' },
  fetchOptions: { retries: 5, timeout: 20_000 },
})

const exitCode = await runCli(cli, process.argv.slice(2))
process.exit(exitCode)

Call an operation directly (bypass the CLI layer)

import { loadSpec, resolveSpec, executeOperation, resolveBaseUrl, resolveAuth } from 'dynamic-openapi-cli'

const spec = await resolveSpec(await loadSpec('./openapi.yml'))
const baseUrl = resolveBaseUrl(spec)
const auth = resolveAuth({ bearerToken: 'sk-…' }, spec.securitySchemes)

const op = spec.operations.find(o => o.operationId === 'listPets')!

const { response } = await executeOperation(
  op,
  { limit: 20, status: 'available' },
  { baseUrl, auth },
)

console.log(response.status, await response.json())

Generate a bash bundle from your own tooling

import { buildBundle } from 'dynamic-openapi-cli'

await buildBundle({
  source: 'https://api.example.com/openapi.json',

})

Useful in a CI step that regenerates the shim on every spec change.

Installation

# once
npm install -g dynamic-openapi-cli

# or per-command
npx dynamic-openapi-cli ...

# or pin it in your project
pnpm add -D dynamic-openapi-cli

Requires Node.js 18+. TypeScript types are shipped.

The family

Three complementary projects, one spec, three output surfaces — pick the one that fits the use case:

Sibling	Output	Runs when	Best when
dynamic-openapi-mcp	Live MCP server (stdio)	Every tool call spins the server	You want real-time introspection, auto-refreshed OAuth tokens, typed tool I/O
dynamic-openapi-cli	Bash CLI (optionally bundled)	Humans and scripts invoke it	You want a commit-friendly shim humans and CI can run
dynamic-openapi-skill	Static SKILL.md	Claude loads it on demand	You want zero runtime, diff-friendly docs, and model-driven calls via curl / fetch

All three share the same parser and auth layer. Switching between them is a matter of pointing them at the same spec.

Head-to-head with the MCP sibling

Same parser, same auth, different consumer:

	dynamic-openapi-mcp	dynamic-openapi-cli
Consumer	AI agents (Claude, Cursor, Windsurf, …)	Humans at a terminal
Operations become	MCP tools	CLI subcommands
Schemas become	MCP resources (openapi://schemas/…)	—
Auth	Env vars + programmatic	Env vars + programmatic (identical)
Transport	stdio / MCP protocol	stdout / stderr / exit codes
Bundle	—	Single-file bash shim
Self-update	—	update subcommand in the shim

Pick the MCP version when you want AI agents to call your API. Pick the CLI version when you want humans, scripts, or CI jobs to call it. Pick the skill version when you want Claude to learn the API from a static markdown file — zero runtime required.

Roadmap

• Shell completion scripts (bash / zsh / fish) — completion <shell> subcommand
• --dry-run flag that prints the curl equivalent without firing the request
• Read request body from stdin (--body=-) for piping
• First-class multipart / binary uploads from file paths (@path, curl-style)
• OAuth2 authorization code flow (browser-based, PKCE, disk-cached tokens)
