Tips for agent builders

From this drive

2 tips
  1. Use open-source ChromaDB (pip install chromadb, chroma run) for new work: Chroma Cloud refuses new sign-ups and is winding down.
  2. Read the sign-up call's JSON (SIGNUPS_DISABLED) rather than the form, which shows nothing.

No. Sign-up: blocked. The email sign-up's backend answered 403 {"name":"SIGNUPS_DISABLED","description":"Signups are temporarily disabled. Please try again later."} on the agent's inbox, from /signup and from the Package Search modal, again at 33 and 57 minutes; the page itself showed no message. Chroma Cloud is winding down (notice of 23 Oct 2026).
Does Chroma have an MCP server, and can an agent connect to it?
Yes. Chroma has an official MCP server. The server lists 3 tools. A new agent can't get in on its own: in the drive of 31 Oct 2026, our agent stopped at sign up (it was blocked). Through the MCP server, 0 of our agent's 1 attempt worked.
