+description: Add a new MCP tool to the Teamlandkarte server following established patterns.
+---
+
+$ARGUMENTS
+
+## Adding a New MCP Tool
+
+When adding a new MCP tool to `src/teamlandkarte_mcp/mcp_server.py`, follow these patterns:
+
+### Naming Convention
+- Use `verb_noun` pattern (e.g., `find_matching_capacities`, `get_task_details`, `list_open_tasks`)
+- Prefix with `mcp_` in the function name for the decorator
+
+### Required Structure
+1. Define the tool function with `@mcp.tool()` decorator
+2. Add clear parameter schemas with descriptions and types
+3. Return Markdown-formatted output (tables for structured data)
+4. Include proper error messages for invalid inputs
+5. Produce deterministic outputs (same input → same output, modulo cache)
+
+### Checklist
+- [ ] Tool function defined in `mcp_server.py` with `@mcp.tool()` decorator
+- [ ] Parameters have type hints and descriptions
+- [ ] Output uses Markdown tables for structured data
+- [ ] Error handling for invalid inputs (return helpful error messages)
+- [ ] No secrets or credentials in output
+- [ ] Read-only database access (never write to Trino)
+- [ ] Add corresponding test in `tests/`
+- [ ] Run `uv run ruff check src/ tests/` and `uv run mypy src/`
+- [ ] Update `docs/assistant_system_prompt.md` with the new tool documentation
+
+### Example Pattern
+```python
+@mcp.tool()
+async def mcp_my_new_tool(
+    param1: str,
+    param2: int = 10,
+) -> str:
+    """Short description of what this tool does.
+
+    Args:
+        param1: Description of param1.
+        param2: Description of param2 (default: 10).
+    """
+    # Implementation
+    result = await some_operation(param1, param2)
+    # Format as Markdown table
+    return format_as_markdown_table(result)
+```
+
+### Security
+- Never expose credentials in tool output
+- Never write to the database
+- Validate all inputs before processing
