Reticle is a proxy + UI for debugging MCP integrations:
Supported transports: stdio, Streamable HTTP, WebSocket, HTTP/SSE.
# npm
npm install -g mcp-reticle
# pip
pip install mcp-reticle
# Homebrew
brew install labterminal/mcp-reticle/mcp-reticle

Example (Claude Desktop-style config):
{
"mcpServers": {
"filesystem": {
"command": "mcp-reticle",
"args": ["run", "--name", "filesystem", "--", "npx", "-y", "@modelcontextprotocol/server-filesystem", "/Users/me/work"]
}
}
}
mcp-reticle ui
mcp-reticle run --log -- npx -y @modelcontextprotocol/server-memory
mcp-reticle proxy --name api --upstream http://localhost:8080 --listen 3001
