This is ONLYOFFICE/docspace-mcp's own configuration. It tells Claude Code how to work on docspace-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything docspace-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docspace-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Overview

MCP server for ONLYOFFICE Apps (formerly DocSpace). Package @onlyoffice/docspace-mcp. Written in TypeScript that Node runs directly (native type stripping, .ts import extensions, no emit step for development). Toolchain versions are pinned in mise.toml (Node 24, pnpm 10).

Commands

pnpm install --frozen-lockfile
pnpm build-app      # esbuild bundle app/main.ts -> bin/onlyoffice-docspace-mcp.js
pnpm build-mcpb     # MCP bundle (manifest.template.json -> mcpb)
pnpm build-detail   # server.json for the MCP registry (from server.template.json)
pnpm build-docs     # regenerate generated sections of tool docs
pnpm lint-types     # tsc (noEmit)
pnpm lint-code      # eslint
pnpm test           # node --test
node --test test/config.test.ts            # single test file
node --test --test-name-pattern="..." test/config.test.ts
pnpm serve          # run app/main.ts with .env loaded
pnpm inspect        # run under @modelcontextprotocol/inspector with DOCSPACE_* env forwarded
  • Tests spawn the bundled ./bin/onlyoffice-docspace-mcp.js, so run pnpm build-app before pnpm test (and build-mcpb/build-detail for mcpb.test.ts/detail.test.ts). CI (.github/workflows/audit.yml) runs: build-app, build-mcpb, build-detail, lint-types, lint-code, test.
  • scripts/env.ts loads .env from the repo root for serve/inspect.
  • scripts/build-docs.ts regenerates the <!--generate ...--> sections in docs/reference/tools.md and docs/getting-started/installation.md.

Architecture

Entry point app/main.ts does all wiring by hand (no DI framework). It parses env via config.EnvSchema, then either:

  • startStdio — a single MCP protocol with credentials from env. If config parsing fails, the server still starts on stdio with mcp.ErroredServer, which reports the config error to the client instead of crashing (logger is muted on stdio).
  • startHttp — an Express app hosting SSE (/sse), Streamable HTTP (/mcp), and optionally OAuth routes. DOCSPACE_TRANSPORT=http enables both SSE and Streamable. A new MCP protocol + API client is created per session in create(req), using auth resolved from the request (req[auth.authKey] / req[oauth.oauthKey]) and per-request settings (toolsets, tools, dynamic) parsed from query/headers by config.SettingsParser.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
