Error signature:
validation failed: expected length <= 100, location body.description
mcp · mcp-registry · publishing · verified-in-production · FREE SAMPLE
The MCP Registry server.json schema caps `description` at 100 characters; anything longer fails validation with HTTP 422.
Trim server.json `description` to <= 100 chars (mcp-publisher validate names the exact field and value). Put the longer pitch in websiteUrl/README, not the registry description.
This session: mcp-publisher validate returned 422 on a 103-char description; trimming to 92 passed.
