Overview

The mcp-proxy MCP server is a publicly available project. Review the upstream repository for installation instructions, supported tools, compatibility, permissions, and current maintenance status.

Configuration

Configuration, transport, authentication, and runtime requirements vary by project. Open the repository before connecting and use the smallest set of credentials and permissions required.

AIHawk is an anti detect browser and web browsing agent, open source, with an MCP server for coding agents: undetected, no captchas, no blocks. It requires an OpenRouter API key for the standalone web UI mode, which can be provided via the --openrouter-key flag or the OPENROUTER_API_KEY environment variable or a .env file in the running directory.

mcp-proxy

A Rust bidirectional MCP proxy supporting SSE and Streamable HTTP transports with OAuth.

Features

  • Multiple transports: SSE and Streamable HTTP
  • OAuth authentication: Full OAuth flow with automatic token refresh
  • Bidirectional proxy: Connect remote servers to local clients or expose local servers remotely
  • Fast and lightweight: Built in rust for performance

Usage

Installing

# from crates.io
cargo install rmcp-proxy
# from github
cargo install --git https://github.com/stephenlacy/mcp-proxy

Building

cargo build --release

Running

The proxy can operate in two modes:

1. Remote Client Mode

Connect to a remote MCP server and expose it as a local stdio server. Supports both SSE and Streamable HTTP transports with automatic detection.

Transport Detection:

  • URLs containing /sse → Uses SSE transport
  • All other URLs → Uses Streamable HTTP transport
  • Override with --transport flag
Basic Examples
# Streamable HTTP
mcp-proxy http://localhost:9090/mcp/instances_abc123

# SSE transport
mcp-proxy http://localhost:8080/sse
mcp-proxy --transport sse http://localhost:8080/events

# Specific
mcp-proxy --transport streamable-http http://localhost:9090/api
Using with Claude or Cursor
{
  "mcpServers": {
    "my-remote-server": {
      "command": "mcp-proxy",
      "args": ["http://example.com/mcp/instances_abc123"]
    },
    "sse-server": {
      "command": "mcp-proxy", 
      "args": ["--transport", "sse", "http://example.com/sse"]
    }
  }
}
2. Local Server Mode

Connect to a local MCP server via stdio and expose it as a remote server. Supports both SSE and Streamable HTTP endpoints.

# Expose as SSE server
mcp-proxy --port 8080 -- your-command --arg1 value1 --arg2 value2
mcp-proxy --port 8080 python mcp_server.py
mcp-proxy --port 8080 -- npx -y @modelcontextprotocol/server-everything

# Or http+streamable
mcp-proxy --port 9090 --transport streamable-http -- python mcp_server.py

mcp-proxy --port 8080 -e KEY VALUE -e ANOTHER_KEY ANOTHER_VALUE -- your-command

Authentication Management

Clearing Auth Cache

If you encounter authentication issues, clear the auth cache:

# Clear all auth data
mcp-proxy reset

# Or manually delete the directory
rm -rf ~/.mcp-auth

Command Line Options

# Transport selection
--transport <TRANSPORT>    # sse, streamable-http, or auto (default: auto)

# Server mode options
--port <PORT>             # Port for local server mode (default: random)
--host <HOST>             # Host to bind to (default: 127.0.0.1)

# Environment variables (server mode)
-e, --env <KEY> <VALUE>   # Set environment variable
--pass-environment        # Pass through all environment variables

# Headers (client mode) 
-H, --headers <KEY> <VALUE>  # Add custom headers

# Reset auth
mcp-proxy reset           # Clear all stored auth data

Logging

The upstream rmcp crate dumps noisy logs unfortunately

Control log verbosity with the RUST_LOG environment variable:

# Minimal logging
RUST_LOG=error mcp-proxy http://example.com/mcp
RUST_LOG=debug mcp-proxy http://example.com/mcp
RUST_LOG=info mcp-proxy http://example.com/mcp

Library Usage

use rmcp_proxy::{
    sse_client::run_sse_client,
    streamable_http_client::run_streamable_http_client,
    StreamableHttpClientConfig, SseClientConfig
};

// Streamable HTTP client
let config = StreamableHttpClientConfig {
    url: "http://example.com/mcp/instances_abc123".to_string(),
    headers: HashMap::new(),
};
run_streamable_http_client(config).await?;

// SSE client  
let config = SseClientConfig {
    url: "http://example.com/sse".to_string(),
    headers: HashMap::new(),
};
run_sse_client(config).await?;
