How to connect Crates Io MCP
Crates Io MCP runs locally from a Node.js package published to the npm registry: crates-io-mcp version 1.0.1. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y crates-io-mcp@1.0.1.
In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):
{
"mcpServers": {
"crates-io-mcp": {
"command": "npx",
"args": [
"-y",
"crates-io-mcp@1.0.1"
]
}
}
