Hydra MCP Server tools

Tool list not available yet

This listing does not currently have a tool list to display. This does not mean the server has no tools; check its documentation for supported capabilities.

We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

Overview

What is Hydra MCP?

Hydra MCP implements a Model Control Protocol server that enables Claude to interact with various client functions through a REST API interface. It consists of a central server that coordinates communication between multiple clients and exposes their functions to Claude via a standardized API.

How to use Hydra MCP?

Start the central server by running python ipc_server.py. Register client functions by sending a POST request to /register_functions with an endpoint name and function list. Then use the MCP tools (get_endpoints(), get_registered_functions(), call_function()) to discover and invoke functions from Claude.

Key features of Hydra MCP

  • Centralized function registry for multiple clients
  • REST API endpoints for function discovery and invocation
  • Standardized communication protocol between clients and Claude
  • Easy-to-use function registration system
  • Automatic function discovery and documentation

Use cases of Hydra MCP

  • Let Claude call functions from multiple remote client applications
  • Register and manage client functions through a central server
  • Discover available functions automatically for dynamic tool use
  • Test client implementations with sample clients (fake_client.py, fake_claude.py)

Frequently asked questions

1

What is the default port for the server?

The server runs on port 6565 by default. This can be changed by modifying the `API_SERVER_PORT` constant in both `ipc_server.py` and `ipc_api.py`.

2

How do I start the server?

Run `python ipc_server.py` from the command line. The server will start and listen for client registrations and MCP requests.

3

How do I register a client?

Send a POST request to `http://localhost:<API_SERVER_PORT>/register_functions` with a JSON body containing an `endpoint` name and a `functions` list (each function has name, description, and parameters).

4

What MCP tools are available?

Three tools are provided: `get_endpoints()` lists all endpoints, `get_registered_functions(endpoint)` retrieves functions for a specific endpoint, and `call_function(endpoint, function_name, arguments)` invokes a function.

5

What are the dependencies?

The project requires FastAPI, uvicorn, requests, and fastmcp.
