In under five minutes you'll be testing product ideas against synthetic personas built from real public data. ## Sign up for Cambium AI If you don't already have an account, create one at [app.cambium.ai](https://app.cambium.ai/) before continuing. You'll use the same login to authorize the MCP in step 4. ## Add the MCP server Tell Claude where to find the Cambium MCP server. Pick how you use Claude. In Claude Desktop, the Cambium MCP is added as a **Custom Connector**. This is a two-step flow: ### Add the custom connector 1. Open Claude Desktop → **Settings → Connectors**. 2. Scroll to **Add custom connector**. 3. Enter a name (e.g. *Cambium AI Product Manager*) and paste the URL below. 4. Save. The connector is now available to everyone on the team. ### Enable it from your library 1. Open **Settings → Connectors**. 2. Find **Cambium AI Product Manager** in your connector library. 3. Click **Connect** and sign in with your Cambium AI account (covered in step 4). $paste into custom connector **Admin-only.** Only the **admin of the Claude team account** can add custom connectors. If you don't see *Add custom connector*, ask your team admin to run the steps on the left. Once it's added, you'll find it in your connector library automatically. ## Open your Connector library Once your admin has added the custom connector, it shows up in your personal Connector library, ready to enable. Open Claude Desktop and go to **Settings → Connectors**. You should see **Cambium AI Product Manager** in the list with a *Connect* button next to it. **Don't see it?** Your team admin hasn't added it yet. Point them at step 2 above. Custom connectors propagate to all team members the moment the admin saves the connector. Leave Settings open. You'll authenticate from here in step 4. ## Authenticate the MCP server The first time you connect, you will need to authenticate with your Cambium AI account. From the Connectors list, click **Connect** next to *Cambium AI Product Manager*. A browser window opens to `app.cambium.ai`. The connector now shows **Connected** in your library and stays signed in across restarts. Each teammate authenticates separately with their own Cambium AI account. ## Verify the connection Confirm the MCP is live before you start using it. Back in **Settings → Connectors**, the *Cambium AI Product Manager* connector should now show a **Disconnect** button and a list of available tools. To kick things off, start a new conversation and ask: *"Help me set up my business case."* Claude will walk you through a short interview to capture your company context — this only happens once, and every research run after will use it. **You're set.** ## Talk to Claude The MCP provides a small set of tools, but you never call them directly. Talk to Claude in plain language and it picks the right one. Here are common ways teams use it. ### Get persona reactions to a new feature Understand objections, willingness to pay and likely points of friction before you commit to building. ### Test messaging and positioning Try headlines, taglines and propositions against your target personas to see which performs best. ### Test a new product direction Explore alternative directions, adjacent markets or repositioned offerings before committing engineering time. ### Validate a new idea from start to finish Four research agents run in parallel (audience sizing, persona interviews, market research and regulatory) and return a clear recommendation. Strong Go Conditional Go Needs Research Reconsider No Go ### Set up or update your business case A short interview captures your company, products, business model and target market, so every piece of research reflects your situation. ### Record what you decided and why Record direction changes, deprioritised ideas and chosen bets, along with the reasoning behind each. Builds a decision log you can revisit later. ## Troubleshooting The most common hiccups and how to clear them. **Authentication didn't stick.** If the server still shows *needs authentication* after you signed in, fully quit Claude Code or Desktop and reopen it. The session needs to reload to pick up the new credentials. **Don't see the connector in Claude Desktop?** Only the Claude team admin can add custom connectors. Once they have, it propagates to everyone's Connector library. Ask them to confirm the URL is `https://api.app.cambium.ai/mcp/product-manager/mcp`. **`claude: command not found`.** The Claude Code CLI isn't installed or isn't on your `PATH`. Install it from [the Claude Code docs](https://docs.anthropic.com/claude/docs/claude-code) and reopen your shell. **Wrong Cambium account?** Disconnect the connector (Desktop) or re-run the authenticate step (Code). The browser will let you switch accounts before approving. The MCP only honors the most recent token. **Start over.** In Claude Code, run `claude mcp remove cambium-ai--product-manager` and repeat step 02. In Claude Desktop, ask your admin to remove the custom connector and re-add it. ### Still stuck? Email us and we'll get you unblocked.
