Crate cratesio_mcp 

An MCP server for crates.io, plus a standalone async crates.io API client.

Cargo features

• mcp (default) – the full MCP server: tools, prompts, resources, shared state, and both transports. Required by the cratesio-mcp binary.
• client – the client (crates.io / docs.rs / OSV) and docs library only, with none of the MCP server dependencies. Depend on it with: cratesio-mcp = { version = "...", default-features = false, features = ["client"] }.
