Description is too long for the tool search_code (MCP Server) for o3-mini

[lutzleonhardt]

Describe the bug
I am using probe as MCP server inside of MCP-Bridge:

"mcp_servers": {
    "probe": {
      "command": "npx",
      "args": ["-y", "@buger/probe-mcp@0.3.0-rc14"]
    }
  }

o3-mini complains about the description size of the search_code tool:

  "error": {
    "message": "Invalid 'tools[0].function.description': string too long. Expected a string with maximum length 1024, but got a string with length 2472 instead.",
    "type": "invalid_request_error",
    "param": "tools[0].function.description",
    "code": "string_above_max_length"
  }
}

To Reproduce
Steps to reproduce the behavior:

• use o3-mini with mcp-server npx -y @buger/probe-mcp@0.3.0-rc14

Expected behavior
The description length should be less/eq than 1024 chars.

Thanks! Yeah prompting for MCP apparently harder then it looks! Will defo test in that setup. Thanks for reporting!
