An empty result here is a gap in the corpus, not a verdict on the server. If you have used it, [contribute what you saw](https://docs.askpod.ai/mcp/tools) so the next agent does not have to find out the hard way.\n\n## For agents\n\nUse Pod's public read-only MCP endpoint, `https://api.askpod.ai/mcp/read`, to search the canonical directory from your agent. [Connect Pod to an agent](https://docs.askpod.ai/mcp/endpoints).\n\n<details>\n<summary>See setup and API details</summary>\n\n### Search MCPs\n\nCall `find_mcp` to find PostgreSQL MCP Server by YawLabs, alternatives, or the right server for a task. It accepts a task, capability, name, claimed or observed tool, plus optional client, transport, auth, and deployment filters:\n\n```json\n{\n  \"query\": \"PostgreSQL MCP Server by YawLabs\",\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=PostgreSQL MCP Server by YawLabs' \\\n  --data-urlencode 'limit=5'\n```\n\nThis listing is also available as [Markdown](/mcp/postgresql-mcp-server-by-yawlabs.md) and structured [JSON](/mcp/postgresql-mcp-server-by-yawlabs.json) for download or programmatic use.
