Elixir MCP SDK

An Elixir implementation of the Model Context Protocol (MCP) SDK. This SDK provides the building blocks for creating MCP servers and clients in Elixir.

Examples

Hello World HTTP Server

A basic HTTP server example to demonstrate Elixir web development with Bandit:

# Run the example server (recommended)
./examples/hello_world/run.sh

# Or run directly (requires --no-halt to keep running)
mix run --no-halt examples/hello_world/application.ex

The server will start on http://localhost:4000 with the following endpoints:

• GET /hello - Returns a greeting message
• GET /health - Health check endpoint
• GET /* - Returns 404 for other routes

Installation

If available in Hex, the package can be installed by adding elixir_mcp_sdk to your list of dependencies in mix.exs:

def deps do
  [
    {:elixir_mcp_sdk, "~> 0.1.0"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/elixir_mcp_sdk.
