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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.03557 |
| Opus 5 | $0.00000 | $0.01778 |
| Sonnet 5 | $0.00000 | $0.00711 |
| Haiku 4.5 | $0.00000 | $0.00356 |
Grade A, and why
fastmcp 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 679 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Features Simple Tool, Resource, Prompt definition Authentication Sessions Image content Logging Error handling SSE CORS (enabled by default) Progress notifications Typed server events Prompt argument auto-completion Sampling Automated SSE pings Roots CLI for testing and debugging Installation npm install fastmcp Quickstart import { FastMCP } from "fastmcp"; import { z } from "zod";
const server = new FastMCP({ name: "My Server", version: "1.0.0", });
server.addTool({ name: "add", description: "Add two numbers", parameters: z.object({ a: z.number(), b: z.number(), }), execute: async (args) => { return String(args.a + args.b); }, });
server.start({ transportType: "stdio", }); That's it! You have a working MCP server.
You can test the server in terminal with:
git clone https://github.com/punkpeye/fastmcp.git cd fastmcp
npm install
Test the addition server example using CLI:
npx fastmcp dev src/examples/addition.ts
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.

fastmcp is a cursor rule published in the GitHub repository Meeting-BaaS/meeting-mcp (30 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,557 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
