tools.39.custom.input_schema: input_schema does not support oneOf, allOf, or anyOf at the top level

We saw the following error in claude code:

API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"tools.39.custom.input_schema: input_schema does not support oneOf, allOf, or anyOf at the top level"},"request_id":"..."}

Pinning to 0.2.2 fixed the issue for us. It seems like maybe 0.13.0 is the first version pushed to npm since 0.2.2: https://www.npmjs.com/package/@perplexity-ai/mcp-server/v/0.13.0?activeTab=versions

current (fixed) configuration

  "mcpServers": {
    "perplexity": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@perplexity-ai/mcp-server@0.2.2"],
      "env": {
        "PERPLEXITY_API_KEY": "${PERPLEXITY_API_KEY}"
      }
    },
  ...
}```

0.13.0 and 0.14.0 are broken. Rolling back to the previous version (bizarrely 0.2.2) works for now.
