Dynamic tool load via Categories can show tools

I'm using Claude 0.13.64 (7d2335) 2025-10-07T18:18:41.000Z

After initially showing me all the available tool categories, I asked to select Version. Here is my conversation, which never results in fetching the version number.

Me: select Version I've selected the Version category. This category has 1 tool available.

The Version category tools are now active and ready to use. Would you like to see what specific tool is available in this category, or would you like to use it to check the

### Support both SSE and stdio

Currently it supports only stdio. There should also be an option to start an SSE server.

### Hierarchical Discovery of Tools

Airflow OpenAPI spec creates a lot of tools. We need a smart way to publish, a hierarchical way to discover tools. 

For example:
If a user asks an operation of DAGs then only tools which are related to DAGS should be listed for LLM to operate on. 

This can be achieved in a two-step process of LLM first categorizing the tools based on categories published in MCP server itself, then discovering tools for that specific category.

### Tools not loading in Claude Desktop

> [!WARNING] 
> Claude Desktop is unable to load the tools due to smaller timeouts.

Timeouts are client-controlled:
- There is no server-side configuration or protocol message to set or override request timeouts.
- The client (e.g., Claude Desktop, MCP Inspector, or your own integration) is responsible for enforcing timeouts and cancelling requests if they take too long.

Below are the logs from Claude Desktop

### Remove Content-Type Header for Zero-Body Requests

DELETE pool operations fail with 400 Bad Request due to incorrectly including Content-Type header when no request body is needed. This violates RESTful principles and Airflow API expectations. The client needs modification to omit Content-Type headers for requests without bodies, ensuring compliance with HTTP specifications and Airflow's API requirements.

### List Tools needs better description

OpenAPI spec has better description which needs to be extracted and add to Tools objects.

Large models like claude 3.5 sonnet has no issues understanding but smaller models might benefit from it.
This will increase context usage a bit. Perhaps should made it optional.
