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 a compatible AI assistant to “calculate LTV with ARPU $50, churn 5%” and having a calculator apply its formula to the inputs. Check that the assistant used the right values and assumptions.

What it does

Provides 17 calculator tools your assistant can call and 12 workflow prompts, where supported by your client.

Why it matters

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

What you don't need

No signup or API key is required. Inputs are sent to our server for calculation; our analytics excludes their values.

“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%, and gross margin is 80%.

pm_calculate_ltv({ arpu: 85, churn_rate: 2.5, gross_margin: 80 })

Here are your results:

Customer Lifetime Value$2,720
Customer Lifespan40 months
Gross Margin80%
AssumptionStable monthly churn

Monthly gross profit per customer is $68. Dividing by 2.5% monthly churn gives an estimated LTV of $2,720. Compare it with CAC using the same customer group.

Which client should I use?

Choose a client you already use, then open its setup tab above.

Already running another MCP server?

You can configure more than one MCP server in a client. This Cursor example adds PM Toolkit alongside Linear; Linear requires its own sign-in.

How PM Toolkit fits alongside Linear, Jira & Atlassian MCPs

MCP integrations can connect product managers to tools such as Linear, Jira, Notion, or PostHog. PM Toolkit provides calculator tools for PM quantitative work — 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.
