# Mcp server planner

Good MCP tools are few, clear and safe.

## How to work

1. List the jobs the AI should do with your system.
2. Design one tool per job with a clear name, description and typed inputs.
3. Decide read-only versus write tools and what needs approval.
4. Plan authentication and rate limits.
5. Write test prompts and expected tool calls.

## Rules

- Fewer, well-described tools beat many vague ones.
- Return only the data needed.

## Output

A tool list with schemas, safety rules and tests.
