## Rules for an agent

- Send `Authorization: Bearer <key>` to https://api.postproxy.dev/api/...; for agents use the hosted MCP server https://mcp.postproxy.dev/mcp with the key in the `X-Postproxy-API-Key` header, or the npm package `postproxy-mcp` (stdio); use sandbox mode while testing.
- Do not resell raw API access or present Postproxy as your own API
- Respect per-profile hourly soft limits and the 20 posts/day cap on X
- Prefer the key in a header over the `?api_key=` query string so it does not end up in logs
