hf-mcp-server AGENTS.md

hf-mcp-server AGENTS.md is an instructions file for Codex, OpenCode from huggingface/hf-mcp-server. It costs 673 tokens per session, scanned A, original, MIT.

A repository guide for a TypeScript monorepo containing an MCP server, its shared libraries, a web interface, and Python end-to-end tests. A monorepo stores multiple related packages in one repository; MCP is a standard way for AI assistants to use tools.

In plain words
What is it for?
It helps with server and web-interface changes, shared MCP tools, package-specific tests, formatting, type checks, and full local runs.
Why use it?
It shows where each package lives and lists the commands for building, checking, testing, and running the whole project.

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

hf-mcp-server AGENTS.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 4d 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.

Repository Guidelines

Subagents

Project Structure & Module Organization

  • packages/app: MCP server plus management web UI. Server code lives in packages/app/src/server, UI in packages/app/src/web, and tests in packages/app/test.
  • packages/mcp: shared MCP tools/library consumed by the server. Source is in packages/mcp/src, with tests in packages/mcp/test and a few *.test.ts files co-located in src.
  • packages/e2e-python: Python-based end-to-end harnesses and fixtures.
  • Root-level docs and support files live in docs/, docs-internal/, scripts/, spec/, and Dockerfile.

Build, Test, and Development Commands

  • pnpm install: install workspace dependencies (Corepack-managed pnpm).
  • pnpm build: build all workspace packages.
  • pnpm dev: watch the MCP package and run the server with HMR.
  • pnpm start: start the production server from packages/app.
  • pnpm lint, pnpm typecheck, pnpm format, pnpm test: run repo-wide checks.
  • Package-specific tests: pnpm -C packages/app test or pnpm -C packages/mcp test.
  • Full local pipeline: pnpm run buildrun (clean, build, lint, test, start).

Coding Style & Naming Conventions

  • TypeScript ESM across packages.
  • Prettier enforces tabs (useTabs: true, tabWidth: 2), semicolons, single quotes, and printWidth: 120.
  • ESLint rules are strict in packages/mcp and server code (no any, consistent type imports, prefer interface type definitions).
  • Tests use .test.ts or .spec.ts naming.

Testing Guidelines

  • Unit/integration tests run with Vitest in both packages/app and packages/mcp.
  • Run all tests with pnpm test or package-specific commands above.
  • No explicit coverage gate is configured; add tests for new tools, transports, or formatting logic.

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.
