xngmcp

xngmcp gives MCP clients and the terminal two local-web tools: web_search via SearXNG and web_fetch for readable public pages.

Install

Requires Rust 1.85 or newer. Docker with the Compose plugin is required for the included SearXNG backend.

From a source checkout, install xngmcp and start the backend:

cargo install --path .

./infra/searxng/bootstrap.sh
docker compose --env-file infra/searxng/.env \
  -f infra/searxng/compose.yaml up -d --wait

The backend listens on http://127.0.0.1:8080. Confirm it and the CLI work:

curl --fail --silent --show-error http://127.0.0.1:8080/healthz >/dev/null
xngmcp search --limit 5 'Rust MCP SDK'

See the SearXNG guide for configuration, operations, and its integration test. See shell integration to install the generated man pages and shell completions.

Pi

Install and configure xngmcp for all Pi projects with the setup guide. Pi's built-in MCP support runs xngmcp serve and exposes mcp__web__web_search and mcp__web__web_fetch as direct tools.

Usage

# Search the web
xngmcp search 'Rust MCP SDK'
xngmcp search --json --limit 5 'Rust MCP SDK'

# Fetch readable text or Markdown from a public URL
xngmcp fetch --format text https://doc.rust-lang.org/book/

# Run the stdio MCP server
xngmcp serve

Configure an MCP client to start xngmcp serve with SEARXNG_URL=http://127.0.0.1:8080. The server exposes web_search and web_fetch. Use --searxng-url or SEARXNG_URL to select another endpoint.

search --json and fetch --json write a single JSON value to stdout. Errors and diagnostics go to stderr. Run xngmcp --help for all commands and options.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
