capacitiesMCP: Instructions file for Claude Code

CLAUDE.md

capacitiesMCP CLAUDE.md is an instructions file for Claude Code from inconceivablelabs/capacitiesMCP. It costs 4,913 tokens per session, scanned A, original, MIT.

Repository instructions for an MCP server that connects to Capacities, a note-taking and knowledge-management service.

In plain words
What is it for?
Use them when compiling, testing, running, or inspecting this TypeScript server and its Capacities API integration.
Why use it?
They document the build, development, testing, debugging, and API-token setup needed to work on the server.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions subagents; mentions Claude Code.

This is inconceivablelabs/capacitiesMCP's own configuration. It tells Claude Code how to work on capacitiesMCP 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 capacitiesMCP configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is cd ../mcp-gateway && docker compose restart mcp-gateway # re-reads catalog/config, respawns child.

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

capacitiesMCP 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 6d 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.

Development Commands

Build and Development

  • Build: npm run build - Compiles src/ to server/dist/ and makes index.js executable
  • Development: npm run dev - Watch mode compilation with TypeScript
  • Start: npm run start - Run the compiled MCP server
  • Inspector: npm run inspector - Launch MCP Inspector for debugging tools
  • Test: npm test - Compiles tsconfig.test.json then runs the Node.js built-in test runner (node --test) over test-dist/test/**/*.test.js

The gates are npm run build (tsc) + npm test. Tests use mocked fetch (no live token, no network) — see test/.

Environment Setup

Required environment variables:

  • CAPACITIES_API_TOKEN - v2 API token (cap-api-…) from the Capacities desktop app (required)
  • CAPACITIES_API_BASE_URL - API base URL (optional, defaults to https://api.capacities.io)
  • LOG_LEVEL - Logging level (optional, defaults to "info"; set debug to emit response-body DEBUG logs)

Dependencies

  • @modelcontextprotocol/sdk: MCP protocol implementation
  • zod: Schema validation for tool parameters
  • dotenv: Environment variable loading from .env files
  • typescript: TypeScript compilation

Architecture Overview

This is an MCP (Model Context Protocol) server integrating Claude with the Capacities knowledge management platform. It runs on the Capacities v2 REST API (developers.capacities.io), migrated from the v1 Beta API (which sunsets 2026-09-01). It exposes a small generic core — search, structure introspection, and object CRUD — and lets the LLM compose those into workflows.

v2 API essentials:

  • Bearer cap-api-… token; every request sends the header X-Capacities-Api-Version: 0.1.0.
  • A token is scoped to a single space. GET /space is singular; search takes no spaceId. Multi-space = multiple tokens. There is no space_id parameter on any tool.

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.
