MCP tool designer
From MCPs: Build Your Own - free, no signup needed.
Prompt template
Design 5 tools for a company-internal MCP server. Company: [describe]. Team: [Growth PM]. For each tool return: - name (snake_case) - description (1 line, model-facing) - inputs (JSON schema sketch) - output format - example PM conversation that triggers it
How to use it well
- Replace every [BRACKETED] placeholder - vague inputs produce vague outputs.
- Add your role and constraints at the top if your assistant does not already know them.
- Critique the first answer explicitly (“too generic because…”) and ask for a second pass.
- Save the version that worked into a project or system prompt so you never retype it.
