My AI tool can't see BYQ after connecting. What should I check?

Usually one of four things: you didn't restart the tool (most only load servers at startup), your key is mistyped or truncated (regenerate and re-paste), the server address is off (copy it exactly), or you're on the Free plan — the MCP needs Pro or Ultra. If you're using the Claude app there's no key involved, so check that the connector shows as connected and that you completed the sign-in. More checks are in Connecting your AI tool.
