## Context
The Exa API returns empty results arrays for all queries despite successful HTTP responses (valid requestId, zero cost) through the MCP server on Claude Desktop and Claude Code.

## Verified resolution
Collaborator theishangoswami: 'there was an issue with our api, it is now fixed' - it was an Exa-side outage, not a client misconfiguration; reporters confirmed it started working with no changes. Related lesson from the same thread: the npm package can lag the repo (0.3.10 on npm vs 2.0.0 in repo), so update the package before debugging.
