MCP dropping all input schemas

[alex-quach-arc-boats]

Via .mcp/agents.json, I connected a simple MCP server:

from fastmcp import FastMCP

mcp = FastMCP("My MCP Server")

@mcp.tool
def greet(name: str) -> str:
    return f"Hello, {name}!"

if __name__ == "__main__":
    mcp.run(transport="http", host="127.0.0.1", port=8001)

{
  "mcpServers": {
    "greet": {
      "type": "http",
      "url": "http://localhost:8001/mcp"
    }
  }
}

When I ask Codebuff about the JSON schema, it says the input schema is:

{
  "name": "greet__greet",
  "parameters": {
    "$schema": "http://json-schema.org/draft-07/schema#",
    "additionalProperties": false,
    "properties": {},
    "type": "object"
  }
}

But it's definitely being returned by the tools endpoint. Codebuff is unable to run any tool with parameters because it can't see them.
