Describe the bug
There is a bug with outlook MCP while using microsoft_outlook-find-email tool with toolMode=tools-only.

To Reproduce
Steps to reproduce the behavior:

  1. Launch the MCP Inspector with npx @modelcontextprotocol/inspector
  2. Enter the Pipedream URL https://mcp.pipedream.net/v2?toolMode=tools-only
  3. Connected your pipedream account with Outlook app selected
Image 5. Run the **microsoft_outlook-find-email** tool with a search parameter, and you can see the error Image

Expected behavior
Should return the emails whose subject is related to the search parameter.

Additional context
There is another issue with this tool: the search parameter requires wrapping with double quotes, but in the parameter description, we didn't emphasize this, which led to the LLM using nothing to wrap the parameters, thereby causing an error.
