Doco is the document space where humans and AI agents write together: block-level stable addressing, optimistic concurrency, and a 29-tool MCP server. See doco.page for the product and the API reference for the OpenAPI 3.1 spec.

Quick start

# 1. Log in (browser device authorization, same mental model as the GitHub CLI)
npx -y --package doco-agent-cli doco login

# 2. Use it
npx -y --package doco-agent-cli doco whoami
npx -y --package doco-agent-cli doco docs ls
npx -y --package doco-agent-cli doco docs cat <docId> -f md
npx -y --package doco-agent-cli doco edit <docId>   # pulls Markdown into $EDITOR; saving writes back

Connect your agent (MCP)

claude mcp add doco -- npx -y --package doco-agent-cli doco mcp

Cursor: paste into MCP settings

{ "doco": { "command": "npx", "args": ["-y", "--package", "doco-agent-cli", "doco", "mcp"] } }

Codex (~/.codex/config.toml):

[mcp_servers.doco]
command = "npx"
args = ["-y", "--package", "doco-agent-cli", "doco", "mcp"]

Gemini CLI (~/.gemini/settings.json or project .gemini/settings.json):

{ "mcpServers": { "doco": { "command": "npx", "args": ["-y", "--package", "doco-agent-cli", "doco", "mcp"], "trust": false } } }

VS Code Copilot (.vscode/mcp.json, or portable workspace .mcp.json):

{ "servers": { "doco": { "type": "stdio", "command": "npx", "args": ["-y", "--package", "doco-agent-cli", "doco", "mcp"] } } }

See the client-specific integration guide for verification and security notes.

MCP toolset (29 tools, deliberately restrained): doco_whoami / doco_list_knowledge_bases / doco_get_tree / doco_list_documents / doco_search / doco_search_v2 / doco_get_document / doco_outline / doco_read / doco_get_blocks / doco_patch_block / doco_insert_blocks / doco_delete_block / doco_batch_edit / doco_create_document / doco_upload_attachment / doco_changes / doco_traverse / doco_create_relation / doco_summary / doco_save_summary / doco_rebuild_summary / doco_update_document / doco_concepts / doco_edit_concepts / doco_refresh_concept_candidates / doco_translations / doco_translation_units / doco_review_translation_unit. Concepts and translations are grouped by action instead of exploding into per-CRUD tools. Enumerable, subscribable resources are also exposed: doco://kb/<id>, doco://doc/<id>.md, doco://doc/<id>/outline.json.

For headless MCP use, environment variables replace doco login: DOCO_TOKEN, DOCO_BASE_URL.

Remote MCP (Streamable HTTP)

Doco 同时提供远程 Streamable HTTP MCP 入口： https://api.doco.page/mcp。它是无状态服务，每个请求都必须携带调用者自己的 Doco API Token；Token 只允许通过 Authorization: Bearer ... 或 X-Doco-Token 请求头传递，不能放进 URL 或 Cookie。服务不会共享或落盘请求中的 Token。

Smithery 的 URL 发布需要把 X-Doco-Token 配置为请求头。使用 Smithery CLI 发布时可以这样声明：

smithery mcp publish "https://api.doco.page/mcp" -n @songofhawk/doco \
  --config-schema '{"type":"object","properties":{"docoToken":{"type":"string","description":"Doco API Token","x-from":{"header":"x-doco-token"}}},"required":["docoToken"]}'

在网页表单中先填写同一个 URL；若页面要求配置字段，字段名使用 docoToken，传输位置选择 HTTP header，名称为 x-doco-token。不要把真实 Token 拼进发布 URL。当前远程入口使用 Doco API Token，而不是 OAuth；需要 OAuth 的客户端应继续使用本地 stdio MCP，或等待 Doco OAuth 授权服务单独上线。为便于目录扫描，initialize 和 tools/list 允许无 Token；实际工具调用仍始终要求调用者自己的 Token。

markdown and tiptap-json views read the whole document unless --around, --max-tokens, or --cursor is given. Pass --max-tokens explicitly to bound context; truncation is reported on stderr together with a next_cursor.

Global --json prints machine-parseable JSON; human-readable output is the default.

Concurrency safety (optimistic concurrency, internalized)

Every write command runs the golden loop automatically:

Read the current version (ETag).
Send the write with If-Match.
On 409 Conflict → re-read the latest version → retry the same change (up to 3 rounds).

Concept updates, source/relation edits, merges, and candidate reviews also read the ETag and send If-Match automatically; concept creation, candidate extraction, and the edits above all generate an Idempotency-Key. Complex aliases / sources / relations arrays accept inline JSON or @data.json file input.

On conflict, doco edit reopens your editor with the latest content while your previous draft is saved as document.conflict-N.md for merging — blind overwrites never happen.

Configuration

Defaults to https://api.doco.page/api/v1; override with --base-url / DOCO_BASE_URL for local development or self-hosted instances. Config lives in ~/.config/doco/config.json (mode 0600):

{ "base_url": "https://api.doco.page/api/v1", "token": "doco_tok_…" }

Environment variables take precedence over the config file: DOCO_BASE_URL, DOCO_TOKEN, DOCO_CONFIG_DIR.

Agent skill

doco skill install --target codex    # installs to ~/.codex/skills/doco/
doco skill install --target claude   # installs to ~/.claude/skills/doco/

The package ships the operating protocol, UI metadata, an acceptance matrix, and isolation verification scripts. The agent works as discover → evidence → act → review → report, running the ETag/If-Match golden loop on every write.
