Corevisor CLI

Local credential management and MCP server for AI assistants. Corevisor lets AI agents execute JavaScript against external APIs while keeping credentials on your machine and enforcing approval policies via a central Hub.

How it works

cv runs as an MCP server (stdio transport) that exposes tools to AI assistants:

• execute_javascript — Run JS code in a sandboxed WASM environment (Boa engine). Outbound HTTP requests to configured domains get credentials injected automatically.
• list_services — Show which API domains are available and whether credentials are set.
• search_api_docs — Search API documentation for configured services by regex pattern.

Every outbound request is checked against the Corevisor Hub's approval rules. Requests can be allowed, denied, or held for human approval before proceeding.

For more information, see corevisor.xyz.
