# Open District

Data for AI that shows its work. Read-only MCP over Streamable HTTP. Every result row carries its source record; every call is written to an append-only audit log.

      "url": "https://mcp.opendistrict.org/mcp",

  }

```

Auth: Bearer token, scoped API key issued per tenant at https://app.opendistrict.org (scopes: `admin`, `api_keys`, `read`).

## Tools (10)

`query(sql[, params])` · `search(q[, filters, limit])` · `schema([source, table])` · `catalog([type, category, search])` · `topology([entity_type, depth])` · `metrics([scope, period])` · `entities([id, type, name, depth])` · `pipelines(action[, id])` · `events(filter[, cursor, limit])` · `audit(filter[, cursor, limit])`

## First cited query

```
tool: query
sql:  SELECT title, source_url, published_at
      FROM federal_register_notices

```

Each returned row includes its source reference. Cite it.
