mcp-llms-full is a cursor rule for Cursor from langfuse/mcp-server-langfuse. It costs 3 tokens per session (43,982 once invoked), scanned C, original, MIT.

A reference guide to applications that support MCP, a standard way for AI applications to connect to tools and data. It compares support for MCP features such as resources, prompts, tools, and sampling across clients including Claude Desktop, Cursor, and Cline.

In plain words
What is it for?
Use it to compare MCP client support and review client-specific details, including examples for Claude Desktop and 5ire.
Why use it?
It helps you check which MCP features a particular application can use before planning an integration.

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 C, and why

mcp-llms-full scanned grade C with 2 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 5d 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 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.
