mcp-quickstart AGENTS.md

mcp-quickstart AGENTS.md is an instructions file for Codex, OpenCode from G12789/mcp-quickstart. It costs 714 tokens per session, scanned A, original, MIT.

Repository guidance for coding agents working on mcp-quickstart, a command-line tool that creates Model Context Protocol (MCP) servers. It documents the project layout, conventions, templates, and testing approach.

In plain words
What is it for?
Use it when changing the CLI, server templates, OpenAPI or curl code generation, schema handling, or related tests.
Why use it?
It gives an agent the project context needed to make changes consistently and test them in the expected way.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

mcp-quickstart AGENTS.md scanned grade A with 1 finding 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.

What this project is

mcp-quickstart is a CLI that scaffolds Model Context Protocol (MCP) servers. It is published to npm as create-mcp-quickstart and invoked via npm create mcp-quickstart@latest or npx mcp-quickstart.

Layout

src/
  index.js      CLI entry: arg parsing, prompts, orchestration
  scaffold.js   recursive template copy + placeholder replacement (incl. extra vars)
  openapi.js    OpenAPI loader + spec->tools codegen (the --from-openapi feature)
  curl.js       curl tokenizer/parser + curl->tool codegen (the --from-curl feature)
  schema.js     JSON/OpenAPI schema -> zod string (+ $ref resolve, infer from value)
templates/
  typescript-stdio/    working TS MCP server (stdio)
  typescript-http/     working TS MCP server (streamable HTTP, Express)
  typescript-openapi/  TS MCP server generated from an OpenAPI spec / curl ({{TOOLS}} injection)
  typescript-cloudflare/ remote MCP server for Cloudflare Workers (createMcpHandler, wrangler)
  typescript-cloudflare-openapi/ API-backed remote MCP server for Workers ({{TOOLS}} injection + http.ts); used when a generated source is combined with --transport cloudflare
  python-stdio/        working Python MCP server (stdio)
  python-http/         working Python MCP server (streamable HTTP, FastMCP)

Conventions

  • Pure ESM, Node >= 18, no build step for the CLI itself.
  • Template files use {{projectName}} / {{projectNameSnake}} placeholders, replaced in scaffold.js.
  • Dotfiles are stored with a leading underscore (_gitignore, _env.example) and renamed on generation, so npm does not mangle them when publishing.
  • Inside generated templates, keep pure logic in tools.ts / tools.py and the MCP wiring in index.ts / server.py. This keeps tests dependency-free.
  • On stdio servers, logs go to stderr only — stdout is the protocol channel.

How to test changes

npm install
node src/index.js tmp-out --lang ts -y      # generate a TS project
node src/index.js tmp-out-py --lang python -y
node src/index.js tmp-api --from-openapi scripts/fixtures/sample-openapi.json -y
node src/index.js tmp-curl --from-curl scripts/fixtures/sample-curl.txt -y
node src/index.js tmp-edge --from-openapi scripts/fixtures/sample-openapi.json --transport cloudflare -y  # API -> Workers
npm run test:e2e                            # scaffolds + builds + tests every variant

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.
