Truto MCP Stdio Proxy

What is Truto MCP Stdio Proxy?

Truto MCP Stdio Proxy is a CLI program that acts as a stdio proxy for HTTP Streamable MCP servers. It reads newline-delimited JSON-RPC messages from stdin, forwards them as POST requests to a specified MCP server endpoint, and writes the responses to stdout. It is intended for developers using clients (like Claude) that expect a stdio-based MCP server but need to communicate with an HTTP-based Streamable MCP server.

How to use Truto MCP Stdio Proxy?

Download a pre-built binary for your platform (Linux, macOS Intel/Apple Silicon, or Windows) from the GitHub releases page and make it executable. Run it from the command line with the required <API_URL> argument, piping JSON-RPC messages via stdin or reading from a file. For example: echo '{"jsonrpc":"2.0","method":"example","params":{},"id":1}' | ./truto-mcp-stdio-linux-amd64-v1.0.0 https://api.truto.one/mcp/<id>. It can also be configured directly in Claude’s mcpServers settings.

Key features of Truto MCP Stdio Proxy

Use cases of Truto MCP Stdio Proxy

• Use MCP tools from a CLI by piping JSON‑RPC requests
• Connect a stdio‑only MCP client (e.g., Claude) to a remote HTTP Streamable MCP server
• Test and debug MCP APIs locally without a full HTTP client
