# Broadside Observer

> A curated, provenance-first catalog of seed cards: papers, posts, and projects worth building from, each with its sources. Readable by people at https://observer.broadside.tech and by agents over a public MCP endpoint.

## MCP

- Endpoint: https://observer.broadside.tech/mcp (also https://observer.anoptic.io/mcp)
- Transport: Streamable HTTP (POST JSON-RPC). No key, no sign-in, CORS open.
- Claude Code: `claude mcp add --transport http broadside-observer https://observer.broadside.tech/mcp`
- Cursor `mcp.json`: `{"mcpServers": {"broadside-observer": {"url": "https://observer.broadside.tech/mcp"}}}`

### Tools

- `query_seeds {"query": "ecs"}`: lists matching cards with their ids.
- `get_seed {"id": "<card id>"}`: returns one card in full, as its original Markdown.

### Raw data

- [cards.json](https://observer.broadside.tech/cards.json): the whole packed catalog.
