Cairo open-sources MCP-native event tracking for agents on Node and Postgres
thehungryindian · reddit · 2026-08-04
The author open-sourced Cairo, an MCP-native event tracking system designed so agents consume events directly instead of polling a dashboard.
- The pitch: if your agent needs to notify you about things like signups, it should call setupproduct, receive a write key, and then let alerts flow through a thin webhook relay.
- Cairo avoids burning LLM tokens on the hot path; it never talks to Slack or Discord directly, and the user’s gateway handles delivery.
- The project is self-hosted and built with Node + Postgres, with a GitHub repo and an MCP package available via npx -y u/ani-hq/cairo-mcp.
