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-documentation 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 9d 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.

What it actually says

MCP Documentation Skill

When to Use

  • When needing to understand the underlying architecture of MCP.
  • When implementing a custom MCP client or server.
  • To research specific protocol features (Resources, Prompts, Tools).

Reference

Official MCP Documentation

Instructions

1. Conceptual Understanding

  • Clients: Applications like Claude Desktop or IDEs that connect to servers.
  • Servers: Lightweight programs that expose tools, resources, and prompts.
  • Transports: The communication layer (usually Stdio or SSE).

2. Implementation Guide

  • SDKs: Use the official SDKs for TypeScript or Python.
  • Core Components:
  • Tools: Executable functions (e.g., calculate_roi).
  • Resources: Data sources (e.g., database://logs).
  • Prompts: Pre-defined templates for LLM interaction.

3. Debugging

  • Use the MCP Inspector to test servers interactively.
  • Check transport logs for message parsing errors.

Quality Gates

  • Compliance with the latest Specification.
  • Use of official SDKs for standardized implementations.
  • Documentation of custom tools/resources for agent discoverability.

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.
