@membranehq/cli

Membrane CLI

A command-line interface for working with Membrane in local development environment.

Installation

npm install -g @membranehq/cli
# or
yarn global add @membranehq/cli
# or
bun install -g @membranehq/cli
# or
pnpm install -g @membranehq/cli

Quick Start

# Initialize with your workspace credentials (interactive)
membrane init

# Or non-interactive
membrane init --key <key> --secret <secret>

# Pull workspace elements
membrane pull

# Make changes, then push back
membrane push

See the Configuration section below for alternative ways to configure credentials.

Authentication

Use membrane login to authenticate via browser-based OAuth. This stores your access token, refresh token, and the API URI locally.

# Login to the default Membrane API
membrane login

# Tenant-scoped OAuth (workspace/tenant-level APIs; see Tenant API commands below)
membrane login --tenant

# Login to a self-hosted instance
membrane login --apiUri http://localhost:9000

# Non-interactive / headless: print the consent URL (stdin not a TTY behaves like this too)
membrane login --non-interactive

# Headless two-step flow (after `login start`, open URL, approve, then exchange the code)
membrane login --apiUri http://localhost:9000 start
membrane login complete <authorization-code>

# Check current login status, API URI, and project defaults
membrane status

# Log out and clear stored tokens
membrane logout

The --apiUri flag sets the API endpoint for this and all subsequent commands. Once logged in, the CLI remembers the API URI so you don't need to specify it again.

During login you select a default workspace and tenant. These defaults are saved in .membrane/config.json (project-level) and used by other commands like connect, and as defaults for --workspaceKey / --tenantKey on tenant API commands.

Connecting External Apps

Use membrane connect to create a connection to a third-party service via browser-based OAuth. Requires prior authentication via membrane login.

# Connect using an integration key (uses defaults from login)
membrane connect --integrationKey hubspot

# Specify workspace and tenant explicitly
membrane connect --integrationKey hubspot --workspaceKey my-workspace --tenantKey my-customer

# Connect using a connector ID
membrane connect --connectorId 123

# Reconnect an existing connection
membrane connect --connectionId abc

# Print the connection URL instead of opening a browser
membrane connect --integrationKey hubspot --no-browser

Tenant API commands

These commands call workspace APIs using the token from membrane login. They use your default workspace and tenant from login unless you pass --workspaceKey and --tenantKey. You can also pass a bearer token with MEMBRANE_TOKEN (see Configuration).

Search workspace elements

membrane search "slack" --elementType connector
membrane search "invoice" --limit 20 --json

Proxy HTTP requests to an external application through a connection

Make an HTTP request via the Membrane connection proxy (similar to curl):

membrane request <connectionId> /v1/resource
membrane request <connectionId> /items?page=1 -X GET
membrane request <connectionId> /items -X POST -d '{"name":"example"}' --json

Use -H 'Header: value' (repeatable), --query key=value, --pathParam id=123, and --rawData to send --data as a plain string.

Manage connections

membrane connection list
membrane connection get <id>
membrane connection get <id> --wait              # Wait until not BUILDING
membrane connection ensure https://slack.com       # Find or create by app URL
membrane connection create "Connect to Slack"

Manage actions (tools)

membrane action list
membrane action list --connectionId <id> --intent "send email"
membrane action get <id> --wait --json
membrane action create "Summarize the latest tickets"
membrane action run <actionId> --connectionId <id> --input '{"query":"..."}'

Connection requests (OAuth flows)

Lower-level control of connection requests (browser connect is usually simpler):

membrane connection-request create --integrationKey hubspot
membrane connection-request get <requestId>

Agent sessions

membrane agent-session list
membrane agent-session create --message "Add a HubSpot connector for contacts"
membrane agent-session get <sessionId> --wait
membrane agent-session send <sessionId> --message "Also add list sync"
membrane agent-session messages <sessionId>
membrane agent-session abort <sessionId>

Use --agent <name> with create to pick a specific agent when supported.

Model Context Protocol (MCP)

Run an MCP server over stdio that exposes Membrane API operations as tools (for editors and agents that speak MCP):

membrane mcp

Requires MEMBRANE_ACCESS_TOKEN, or MEMBRANE_WORKSPACE_KEY and MEMBRANE_WORKSPACE_SECRET (or values in membrane.config.yml / after membrane init).

Experimental commands

These may change or behave differently in future releases.

Real-time sync (TUI)

membrane sync --watch              # Required: watch mode
membrane sync --watch --rps 5     # Optional: cap requests per second (1–1000)

Interactive configuration

membrane config    # Interactive config UI (alias: membrane install)

Code generation

From local workspace actions, generate OpenAPI or TypeScript. Currently only schema generation is supported, so --schemasOnly is required:

membrane codegen \
  --actions list-files,get-file-by-id \
  --out src/generated \
  --target openapi \
  --schemasOnly

--target is openapi or typescript.

Integration tests

membrane test run connectors/hubspot
membrane test run actions/create-contact --fix

See membrane test run --help for path examples.

Open workspace in console

membrane open uses workspace credentials (not OAuth login tokens). It requires MEMBRANE_WORKSPACE_KEY and MEMBRANE_WORKSPACE_SECRET in environment variables or membrane.config.yml (for example, after membrane init).

membrane open

Synchronizing Workspace

Use membrane init to configure workspace credentials, then membrane pull and membrane push to synchronize workspace elements between local files and the remote workspace.

# Initialize workspace configuration
membrane init --key <key> --secret <secret>

# Pull workspace elements from remote
membrane pull [--force]

# Push workspace elements to remote
membrane push [--force]

# Show what would change on push without applying anything
membrane diff

Configuration

The CLI can be configured using either environment variables or a configuration file (membrane.config.yml). Environment variables take precedence over the configuration file.

Environment Variables

export MEMBRANE_WORKSPACE_KEY=<your-workspace-key>
export MEMBRANE_WORKSPACE_SECRET=<your-workspace-secret>
export MEMBRANE_API_URI=https://api.your-membrane-instance.com  # Optional: for self-hosted instances (default: https://api.integration.app)
export MEMBRANE_CONSOLE_URI=https://console.your-membrane-instance.com  # Optional: for self-hosted instances (default: https://console.integration.app)
export MEMBRANE_TEST_CUSTOMER_ID=<test-customer-id>  # Optional: for testing integrations
export MEMBRANE_ACCESS_TOKEN=<token>  # Optional: bearer token (e.g. for `membrane mcp`)
export MEMBRANE_TOKEN=<token>  # Optional: bypass workspace token exchange for tenant API commands

MEMBRANE_ACCESS_TOKEN and MEMBRANE_TOKEN are not interchangeable:

• MEMBRANE_ACCESS_TOKEN is used by membrane mcp to call the API directly (typically a workspace-scoped access token).
• MEMBRANE_TOKEN is a user/tenant bearer token used by tenant API commands; when set, the CLI skips deriving a workspace+tenant token from login defaults.

Configuration File

The CLI uses a configuration file at membrane.config.yml:

workspaceKey: <your-workspace-key>
workspaceSecret: <your-workspace-secret>

# Optional
apiUri: https://api.your-membrane-instance.com # For self-hosted instances (default: https://api.integration.app)
consoleUri: https://console.your-membrane-instance.com # For self-hosted instances (default: https://console.integration.app)

testCustomerId: test-customer # Internal ID of customer for testing integrations

Note: When both environment variables and configuration file are present, environment variables take precedence.

Self-Hosting: For details on self-hosting Membrane, see Self-Hosting Documentation.

Version Control

membrane.config.yml contains secrets. You should exclude it from version control.

membrane folder can and should be stored in version control to keep your integration configurations versioned.

Transferring elements between workspaces with pull and push

The CLI provides a pull and push command to transfer workspace elements between environments. You'd typically use this to move integrations, actions, flows, and other configurations from development to production.

How it works:

Workspace elements (integrations, actions, data sources, flows, field mappings, etc.) are stored as YAML files in the ./membrane directory. Each element has a unique UUID that identifies it across workspaces.

When you pull, the CLI:

• Exports all elements from the remote workspace as YAML
• Compares them with your local ./membrane directory by UUID
• Identifies what's new, changed, or deleted in the remote workspace
• Downloads connector source code for custom connectors
• Updates your local files to match the remote state

When you push, the CLI:

• Packages your local ./membrane directory as an export
• Compares it with the current state of the remote workspace
• Identifies what's new, changed, or deleted locally
• Uploads connector source code for custom connectors
• Applies the changes to the remote workspace

Changes are applied in dependency order (integrations before integration-level elements, parents before children) to maintain referential integrity. Conflicts occur when an element exists in only one location; use --force to resolve by preferring the source.

When you diff, the CLI:

• Compares current local state with the remote workspace
• Displays a unified diff of all changes

Useful for previewing what push would do before actually applying changes.

Example:

# Pull from development workspace
export MEMBRANE_WORKSPACE_KEY="dev-workspace-key"
export MEMBRANE_WORKSPACE_SECRET="dev-workspace-secret"
membrane pull

# Push to production workspace
export MEMBRANE_WORKSPACE_KEY="prod-workspace-key"
export MEMBRANE_WORKSPACE_SECRET="prod-workspace-secret"
membrane push
