mcp is a cursor rule for Cursor from Bilal140202/the-lord-of-the-skills. It costs 0 tokens per session (535 once invoked), scanned A, a copy of mcp, MIT.

A reference guide to MCP, a standard protocol that lets applications, servers, and language models exchange context and use tools.

In plain words
What is it for?
Checking MCP concepts, specification versions, transport choices, lifecycle rules, tool integration, and related implementation practices.
Why use it?
It gives developers a concise explanation of MCP's sessions, messages, connections, cancellation, progress, resources, prompts, and tools.

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 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 12d 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.

Origin

This is a copy

100% identical to mcp — 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.

Model Context Protocol (MCP)

MCP is a standard protocol to exchange contextual data between clients, servers, and LLMs. This rule provides an at-a-glance reference for key concepts, spec versions, tooling, and best practices.

Core Concepts

  • Lifecycle: Define session start/end, request and response phases.
  • Messages: JSON-encoded context, prompts, and completions.
  • Transports: HTTP, WebSocket, gRPC—pluggable transports for message delivery.
  • Cancellation: Send cancellation messages to abort in-progress requests.
  • Ping (Heartbeat): Keep connections alive; detect timeouts.
  • Progress: Stream partial results and progress updates.
  • Roots: External content references (e.g. code, docs) managed by ID.
  • Sampling: Control streaming vs. non-streaming completions; fine-tune sampling parameters.
  • Tools: Plugin external actions and APIs into LLM workflows.

Specification Versions

  • Basic 2024-11-05: Overview, lifecycle, messages, transports, utilities (cancellation, ping, progress).
  • Server/Client 2024-11-05: Prompts, resources, roots, sampling, tools, logging, pagination.
  • Extended 2025-03-26: Authorization, architecture refinements, changelog.
  • Drafts: Early designs; consult changelog for breaking changes.

SDKs & Examples

Best Practices

  • Always annotate messages with spec version and timestamp.
  • Use roots to manage large contexts; avoid embedding bulky data inline.
  • Gracefully handle cancellation and errors; propagate clear error codes.
  • Emit progress events for long-running streams to improve UX.
  • Maintain a ping schedule to detect and recover dropped connections.
  • Leverage tools to encapsulate external API calls and side effects.
  • Follow spec utilities: logging, pagination, and completion conventions.
  • Review the official spec and changelog regularly to stay up to date.

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.
