It accepts a task, capability, name, claimed or observed tool, plus optional client, transport, auth, and deployment filters:\n\n```json\n{\n  \"query\": \"REAPER MCP\",\n  \"limit\": 5\n}\n```\n\nUse the returned canonical ID with `inspect_mcp` to read deployments, source claims, live measurements, and decision-useful GitHub reports.\n\nPrefer HTTP? Search the same canonical index directly:\n\n```bash\ncurl --get 'https://api.askpod.ai/v1/mcps' \\\n  --data-urlencode 'query=REAPER MCP' \\\n  --data-urlencode 'limit=5'\n```\n\nThis listing is also available as [Markdown](/mcp/reaper-mcp.md) and structured [JSON](/mcp/reaper-mcp.json) for download or programmatic use.
