Review this generated MCP-style handler before connecting it to an agent.
Implement read_source for authenticated callers: accept exactly one relative .ts path under /srv/project/src, reject missing or extra fields with a structured error, read at most 4096 valid UTF-8 bytes, and return canonical path and byte count matching the declared output schema.
