## Description

**As an** LLM user,  
**I want to** remove output schemas from the MCP tool definitions,  
**so that** this schema can't pollute the context window of the LLM.

**As a** developer,  
**I want to** remove output schemas from the MCP tool definitions,  
**so that** a feature that's barely implemented by existing MCP clients does not make changes to the output structure harder than necessary.

### Acceptance criteria

*   MCP tools do not expose an output schema anymore
    
*   Development/Test mode do not validate the result against the output schema anymore
    

### Technical notes

While we don't perform automated validations of the output schema anymore, it should still be a goal to stay "close" to the APIv3 schema for practical purposes.

While there are feature requests to optimize the result structure for the MCP use case, I (Jan) think that we should still take these as optimizations _on top of_ a base structure that we inherit from.
