Calven's nine product marketing agents keep one source of truth on your market, buyers and positioning. Calven MCP puts it inside Claude, ChatGPT, Codex, Cursor, Copilot and other MCP clients that sign in with OAuth (see client support), so sales, marketing, product and leadership work from the same answers your team approved.

What it reads, and what it won't do

Your assistant reads, with sources: positioning, messaging, ICP and product brief; competitor dossiers and battlecards; personas; calls, customer quotes and win/loss; market trends; Insights dashboards; and CRM accounts and deals where your workspace allows it.

• Results carry their sources. An empty result says nothing is recorded. Calven does no web search, and its server instructions tell the model not to fill gaps from its own knowledge.
• Thirteen read tools and one review action, listed in the tool catalog, plus four server prompts. The action, review_against_personas, starts a review task in Calven and returns findings. No tool edits your workspace content, and nothing is published or sent.
• Your permissions. Each user signs in as themselves and sees only what their Calven role allows. Admins decide whether transcripts and pipeline are readable over MCP. Removing a user removes their MCP access.

[!IMPORTANT] Answers contain your company's confidential data. Use an AI client and model provider your organization has approved. See data handling.
