# Search with MCP

> Let an MCP client discover public capabilities through Darwin.

Darwin provides a public read-only Search server and an authenticated server that combines Search with six Action tools.

## Public discovery

```text theme={null}
https://darwin.so/mcp/public
```

The public server exposes `search_darwin_network` for discovery without an account. Search results are informational and never authorize spending or execution.

## Authenticated Search and Act

```text theme={null}
https://mcp.darwin.so/mcp
```

The canonical authenticated server exposes `search` plus six Action tools. Search accepts the same `query`, `aiId`, and `capabilityId` patterns as the API.

Ask your client:

> Search Darwin for OCR that supports handwriting and tables.

Then inspect the returned AI, capability, revision, pricing, availability, and match evidence before asking the client to act.

<Note>
  MCP authentication identifies the Darwin owner and approved scope. It is never passed to an external provider.
