Common questions

Is Grpc Invoke MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.5) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

gRPC Invoke MCP

grpc-invoke-mcp is an MCP server for calling gRPC methods from AI agents like Claude Code, Codex, Cursor, and other MCP-compatible tools.

It gives agents a simple way to inspect gRPC APIs and invoke unary RPCs using either server reflection or local .proto files. This is useful when you want an agent to explore services, understand request and response schemas, make real gRPC calls, and test gRPC integrations during agent-driven development without writing one-off scripts.

Features

Call gRPC methods from MCP-compatible agents
Describe gRPC services, methods, and message types
Use server reflection or local .proto files
Connect over TLS or plaintext HTTP/2
Send custom metadata headers
Pass JSON request bodies for unary RPCs
Works with Claude Code, Codex, Cursor, and other MCP clients

Installation

Run the server with npx:

npx -y @grulex/grpc-invoke-mcp@latest

The package downloads a platform-specific grpc-invoke-mcp binary during installation.

Agent Setup

Claude Code

Project config file: .mcp.json

"mcpServers": { "grpc-invoke": { "type": "stdio", "command": "npx", "args": ["-y", "@grulex/grpc-invoke-mcp@latest"] } } }

Optional CLI setup:

claude mcp add --transport stdio grpc-invoke -- npx -y @grulex/grpc-invoke-mcp@latest

Codex

User config file: ~/.codex/config.toml

[mcp_servers.grpc-invoke]

command = "npx" args = ["-y", "@grulex/grpc-invoke-mcp@latest"]

Optional CLI setup:

codex mcp add grpc-invoke -- npx -y @grulex/grpc-invoke-mcp@latest

Cursor

Project config file: .cursor/mcp.json

"mcpServers": { "grpc-invoke": { "type": "stdio", "command": "npx", "args": ["-y", "@grulex/grpc-invoke-mcp@latest"] } } }

You can also install it globally in ~/.cursor/mcp.json.

Available Tools

`grpc_describe`

Use this tool to inspect services, methods, and message types.

Common use cases:

list services exposed by a gRPC server
inspect a method signature before calling it
explore message schemas through reflection
describe APIs from local .proto files

`grpc_call`

Use this tool to invoke unary gRPC methods with a JSON request body.

Common use cases:

call internal microservices from your agent
test request and response payloads
send auth headers or other gRPC metadata
connect to local, staging, or production-safe endpoints

Example Prompts

"Describe the services exposed by localhost:50051 using reflection."
"Show the request schema for helloworld.Greeter/SayHello."
"Call helloworld.Greeter/SayHello on localhost:50051 with { \"name\": \"World\" }."
"Invoke package.Service/Method using proto_files and import_paths instead of reflection."

How It Works

This package exposes an MCP server over stdio. Your agent starts it locally and discovers tools such as:

grpc_describe for schema inspection
grpc_call for unary RPC invocation

Under the hood, the npm package launches a native grpc-invoke-mcp binary bundled at install time. The binary supports:

gRPC server reflection
local .proto definitions
plaintext or TLS connections
request metadata headers

Supported Platforms

The installer currently targets:

macOS Apple Silicon
macOS Intel
Linux x64
Linux ARM64
Windows x64
Windows ARM64

Troubleshooting

`npx` cannot start the server

Make sure Node.js and npx are installed and available in your PATH.

The binary download fails

The npm package downloads a release artifact during installation, so your machine needs network access to GitHub Releases.

Reflection does not work

If the target server does not expose gRPC reflection, use local .proto files and import_paths instead.

TLS or connection errors

Check the target host, port, TLS settings, and whether the server expects plaintext or TLS.

The agent does not use the MCP server

Confirm the config file is in the right location for your client, restart the client if needed, and verify the server appears in the MCP list or tools panel.

Why Use grpc-invoke-mcp

If you work with gRPC services, this MCP server lets AI agents inspect and call those services directly. Instead of translating API details by hand, you can let Claude Code, Codex, Cursor, or other MCP-compatible agents explore the contract and execute safe, targeted requests for debugging, integration work, API discovery, and gRPC testing in agent-driven development workflows.
