rust-mcp-expert

rust-mcp-expert is an agent for Claude Code from asleekgeek/claude-multiagent-catalogue. It costs 24 tokens per session (3,028 once invoked), scanned C, original, no licence file.

An expert guide for building Model Context Protocol servers in Rust with the rmcp SDK and Tokio, a library for asynchronous Rust programs. MCP servers let AI tools connect to external data or actions.

In plain words
What is it for?
Use it to design, implement, or troubleshoot MCP servers written in Rust with Tokio.
Why use it?
It helps developers handle the Rust-specific setup and asynchronous code needed for MCP server development.

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

rust-mcp-expert scanned grade C with 1 finding 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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.
