PM Toolkit MCP Server is a free Model Context Protocol (MCP) server that provides 17 product management calculator tools and 12 workflow prompts directly inside AI assistants like Claude Code, Cursor, and Codex. Product managers can calculate LTV, CAC, RICE scores, A/B test sample sizes, unit economics, market sizing (TAM/SAM/SOM), NPS, and more without leaving their AI workflow. Unlike other MCP servers for product managers that focus on project management integrations (Linear, Jira, Notion), PM Toolkit is the only MCP server offering quantitative PM calculator tools. Setup requires one command: claude mcp add --transport http pmtoolkit https://pmtoolkit.ai/api/mcp. Free, no authentication, no data stored.

What is MCP, in PM terms?

MCP (Model Context Protocol) is an open standard from Anthropic that lets your AI assistant call live tools. For a PM, it means asking Claude, Cursor, or ChatGPT to “calculate LTV with ARPU $50, churn 5%” and getting a real number, not a hallucination — the same way Linear’s MCP lets your AI read tickets, or Jira’s MCP lets it move work between sprints.

What it does

Exposes 17 PM calculator tools and 12 workflow prompts as live functions your AI can call.

Why it matters

You stop tab-switching. Calculations happen in your existing conversation, with the context already there.

What you don't need

No code. No signup. No API key. No data sent to us — calculations are stateless.

“I built the PM Toolkit MCP server because switching tabs to run a quick LTV calculation broke my flow in Claude Code. Now I chain three calculators together in a single conversation — context stays, momentum stays.”

Claude Code

Calculate LTV for our SaaS product. ARPU is $85/month, monthly churn is 2.5%.

pm_calculate_ltv({ arpu: 85, churnRate: 2.5 })

Here are your results:

Customer Lifetime Value$3,400
Customer Lifespan40 months
Health StatusExcellent
BenchmarkTop 25% SaaS

With 2.5% monthly churn and $85 ARPU, your LTV of $3,400 is strong. Target an LTV:CAC ratio of 3:1 or higher for sustainable growth.

How PM Toolkit fits alongside Linear, Jira & Atlassian MCPs

Most MCP servers built for product managers are operational — they wrap Linear, Jira, Notion, or PostHog. PM Toolkit is the only MCP server built for PM quantitativework — the LTV, RICE, A/B test, and market sizing math that lives in spreadsheets today. Run them side-by-side: Linear MCP for tickets, PM Toolkit for the metrics that justify the tickets.
