rust-mcp-sdk: A high-performance, asynchronous toolkit for building MCP servers and clients in Rust

by rust-mcp-stack · MCP Server · ★ 195

Last updated: · Indexed by AgentSkillsHub · Auto-synced every 8h

Security audit verdict: SAFE · quality 69/100

None of the 42 rules matched — no credential harvesting, no data exfiltration, no curl-pipe-shell installer. Scanned against 42 published rules built on the SlowMist agent-security taxonomy, refreshed every 8 hours. Full audit →

The quality score combines nine heuristic checks of the repo and its README: completeness, clarity, specificity, examples, structure, agent readiness, step-by-step content, instruction quality and security notes. It rates how well the project explains itself to an agent, not the code.

About rust-mcp-sdk

Rust MCP SDK A high-performance, asynchronous Rust toolkit for building MCP servers and clients. Focus on your application logic - rust-mcp-sdk handles the protocol, transports, and the rest! This SDK fully implements the latest MCP protocol version (2025-11-25), with backward compatibility built-in. provides the necessary components for developing both servers and clients in the MCP ecosystem.

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
