Stacktrace (YC F26) — See and control what your agents actually do

We’re building Stacktrace to help teams see what AI agents actually do, detect risky behavior, and alert the people responsible. Administrators can also deploy policies that block unapproved tools, such as MCP servers and plugins, before agents use them.

Is this you?

If you're behind Stacktrace: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.

Sourced from the company's Y Combinator directory entry, from the company's own site, read directly on 2026-10-09 (stacktrace.ai), and from the public GitHub account that record links to (stacktrace-ai).
