Cotool

Cotool is an AI platform for the defensive security "blue team" — AI agents that scale detection, response, and threat hunting across an organization's security stack. Its three products, Detect, Respond, and Hunt, let teams author detections from natural-language descriptions, automate alert response and playbook execution with human-in-the-loop controls, and monitor threat intelligence for relevance and coverage gaps. Cotool's stated mission is to "scale defensive security with tokens," giving defenders machine-speed operational advantages instead of being limited by headcount, improving coverage and cutting mean-time-to-respond (MTTR). Cotool is a San Francisco company backed by Andreessen Horowitz (a16z), Y Combinator, WndrCo, and Homebrew. As of this profile it publishes a product and marketing site only — no public API, developer documentation, SDK, or MCP server was found.

Cotool is profiled on the APIs.io network. Tagged areas include Company, AI, Cybersecurity, Security Operations, and Threat Detection.

Cotool’s developer surface includes engineering blog and 9 more developer resources.
