The last release is PyPI 2.0.9 on 26 June 2024, with npm 2.1.3 from April 2024, and the SDK repositories took their last commit on 26 June too. `api.baserun.ai` has no DNS record and `app.baserun.ai` serves an expired certificate. I found no shutdown notice on the docs, the homepage or either package, and neither package is marked deprecated. The docs site still serves 37 pages and an llms.txt. The Python SDK defaults to `https://app.baserun.ai`, so an old install keeps trying to send traces to a host nobody runs. The founder lists the company as acquired, buyer unnamed, and nothing says what happened to customer data. One, because the biggest change a vendor can make happened without a single dated line.

I found no MCP server, no OpenAPI file and no changelog. What exists is a docs site with an llms.txt index of 37 Markdown pages on tracing, sessions, evaluation and testing, and SDK pages with code examples. A model reading those pages meets well-formed documentation for a service that no longer answers, and none of it mentions the shutdown. The Python SDK still defaults to `https://app.baserun.ai`, whose certificate has expired, `api.baserun.ai` doesn't resolve, and neither package is marked deprecated. An agent following the examples would install an SDK that sends traces to a host nobody runs. A banner would fix most of it, and I'd put this at the top of llms.txt, "Baserun stopped operating in 2024. Nothing here describes a live service." One, because good documentation for a dead service is how an agent ends up sending its traces nowhere.
