概览

What is Grpc Invoke Mcp?

Grpc Invoke Mcp is an MCP server that lets AI agents (Claude Code, Codex, Cursor, etc.) inspect gRPC APIs and invoke unary RPCs. It supports either server reflection or local .proto files, enabling agents to explore services, understand schemas, and make real gRPC calls without writing one-off scripts.

How to use Grpc Invoke Mcp?

Install and run with npx -y @grulex/grpc-invoke-mcp@latest. Then add it as a stdio MCP server in your agent’s configuration file (e.g., .mcp.json for Claude Code, .codex/config.toml for Codex, or .cursor/mcp.json for Cursor). The package downloads a platform-specific binary during installation.

常见问题

What tools does Grpc Invoke Mcp provide?

Two tools: `grpc_describe` for schema inspection and `grpc_call` for invoking unary RPCs.

How do I install Grpc Invoke Mcp?

Run `npx -y @grulex/grpc-invoke-mcp@latest`. A platform-specific binary is downloaded during installation. Node.js and npx must be in your PATH.

Does Grpc Invoke Mcp require gRPC reflection?

No. If the target server does not expose reflection, you can use local `.proto` files and import paths instead.

What platforms are supported?

macOS (Apple Silicon and Intel), Linux (x64 and ARM64), and Windows (x64 and ARM64).

What if the binary download fails during installation?

Your machine needs network access to GitHub Releases. Ensure internet connectivity and retry.
