  Lookup MCP servers across the <a href="https://registry.modelcontextprotocol.io">official MCP Registry</a>, <a href="https://smithery.ai">Smithery</a>, and <a href="https://pulsemcp.com">PulseMCP</a> from one CLI and Python library. Stdlib-only, no runtime dependencies.

## Why

Tools that need to enrich raw MCP server detections — e.g. a security dashboard that catalogs which MCP servers developers are running, an IDE assistant that needs canonical install metadata, or an SBOM pipeline — typically resort to HTML-scraping third-party catalogs because most registries don't expose a clean JSON API.

`mcp-lookup` wraps the three main MCP catalogs (`registry.modelcontextprotocol.io`, `api.smithery.ai`, and `api.pulsemcp.com`) behind a tiny, stable interface. It gives you:

- **Canonical server metadata** by name or repo URL: description, publisher namespace, version, packages (`npm`/`pypi`/`docker`), and remote transports (`stdio`/`sse`/`streamable-http`).
- **Three-source aggregation**: `search` fans out to all three sources **in parallel** and returns merged results, each labeled by `_source`. `get` prefers the registry (canonical), then falls back to Smithery, then PulseMCP.
- **Parallel search for low latency**: search latency is bounded by the slowest source (~1.2s) instead of the sum of all three (~5s). One slow or unavailable source never blocks the others.
- **Authoritative tool lists**: Smithery entries include the server's `tools[]` with input schemas, which the registry does not expose.
- **Community coverage**: PulseMCP adds GitHub star counts, package download counts, and long-tail community servers not (yet) in the official registry.
- **URL → name resolution**: hand it a `https://github.com/owner/repo` (or a vendor domain) and every …
