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 | $0.00692 | $0.00692 |
| Opus 5 | $0.00346 | $0.00346 |
| Sonnet 5 | $0.00138 | $0.00138 |
| Haiku 4.5 | $0.00069 | $0.00069 |
Grade A, and why
Youtube-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.
This is a copy
100% identical to youtube-mcp-server AGENTS.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidelines
Project Structure & Module Organization
src/index.ts: MCP resource and tool registration shared by transports.src/stdio-server.ts: local stdio transport used by the npm executable.src/http-server.ts: Streamable HTTP/mcptransport and health endpoint.src/youtube-service.ts:YouTubeServicewrapper for YouTube Data API calls, transcript retrieval, and caching.src/types/youtube-types.ts: shared TypeScript interfaces and error types.src/types.d.ts: external module declarations.- Build output is generated in
dist/(do not edit manually).
Build, Test, and Development Commands
npm install: install dependencies.npm run build: compile TypeScript (src/) todist/.npm start: run built server (dist/http-server.js) onPORT(default3000).npm run dev: run directly from TypeScript withts-nodeloader.npm test: compile and run the HTTP server smoke tests.npm run test:live: exercise the flagship research tool against a public YouTube video.npm run clean: remove build artifacts.- Docker flow:
docker build -t youtube-mcp-server .thendocker run -p 3000:3000 --env-file .env youtube-mcp-server.
Coding Style & Naming Conventions
- Language: TypeScript (strict mode, NodeNext modules, ESM imports).
- Use 2-space indentation and semicolons, matching existing files.
- Prefer explicit interfaces/types for tool inputs and API responses.
- Use descriptive camelCase for variables/functions, PascalCase for classes/types, and kebab-case for MCP tool names (for example,
search-videos). - Keep imports module-safe for NodeNext (
./file.jsstyle for local imports).
Testing Guidelines
- Minimum validation for each change:
npm testmust succeed.- For protocol changes, verify
/mcpwith MCP Inspector (npx @modelcontextprotocol/inspector). - Exercise affected tools/resources with realistic IDs and confirm error handling for invalid inputs.
- Add transport-level tests under
tests/using Node's built-in test runner.
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.
