mcp-bridge

A Model Context Protocol (MCP) bridge that connects remote streamable HTTP servers to MCP clients using stdio transport.

Features

• Fast: Starts in <1ms, faster than Node.js runtimes.
• Lightweight: Uses 2-5 MB of RAM.
• Single Binary: No dependency on Node or NPM. Drop in a compiled binary.

Installation & Building

Install the Rust toolchain, clone the repository, and run:

# Compile an optimized production binary
cargo build --release

Build the binary at ./target/release/mcp-bridge.

Configuration

Update your client's MCP configuration to register a remote HTTP server as an MCP transport bridge:

{
  "mcp": {
    "searxng": {
      "type": "local",
      "command": [
        "/path/to/mcp-bridge/target/release/mcp-bridge",
        "http://127.0.0.1:18765/mcp"
      ]
    }
  }
}

Replace /path/to/... with the absolute path to your compiled binary, and http://127.0.0.1:18765/mcp with your actual remote MCP endpoint.
