MCP server '{server_id}' not found.

Error message

MCP server '{server_id}' not found.

What it means

Lookup guard in the approve flow: get_mcp_server returned no DB row for the given server_id, so there is nothing to approve. Usually means the id is wrong, the submission was deleted, or the caller is pointing at a config-defined server that never gets a DB row.
