The Permutive MCP server is in a testing phase with partnering customers. Access is invitation-only and the tool interfaces may change. If you would like access, please contact your Permutive representative.

​
What it is

The Permutive MCP server gives AI agents a direct, structured line into your audience data. Connect an agent — such as Claude — to your Permutive account, and it can explore and reason about your cohorts in plain language: find audiences that match a brief, pull their detail, and combine them to check reach, all without you writing queries or leaving the conversation. It implements the Model Context Protocol, an open standard — published by Anthropic and adopted across the major model providers and agent frameworks — for connecting AI agents to external systems. The shorthand is “USB-C for AI”: instead of a bespoke integration per agent, the agent and the service agree on a common protocol. The agent reads the tool list, understands each tool from its description, and calls it — no glue code required.

An open protocol

MCP is vendor-neutral. The server works with Claude, ChatGPT, Cursor, and any agent or framework that speaks the protocol — you are not locked into a model provider to use it.

Structured, not scraped

Every tool has a typed schema and a description the agent reads at runtime. No HTML parsing, no fragile screen-scraping — the agent gets a precise, typed definition of each tool’s inputs and outputs.

Organization-scoped

Authentication is per organization. An agent acting on your behalf sees only your data — your cohorts, domains, and activations. The same boundaries that apply in the Permutive UI apply here.

​
What you can do

The tools cover the full discovery-to-evaluation loop a commercial team runs when responding to a brief:
  • Discover audiences — find cohorts matching a natural-language brief (“high-income readers interested in luxury cars”) across one or more workspaces.
  • Understand a cohort — look up a cohort’s name, type, state, tags, and which workspaces it is available in.
  • Measure reach — estimate how many users and page views an audience reaches, with optional breakdowns by cohort, domain, device, country, and workspace.
  • Compose audiences — combine cohorts and measure the result, iterating as you refine against the brief.
The tools explore and evaluate your audience data — they do not create, edit, or delete anything in your account. These bullets are a curated tour, not the full list — see the All Tools reference for every tool, with parameters, return shapes, and example prompts.

​
Example use cases

  • A planner sizing an audience for a campaign brief, directly in their AI assistant.
  • An analyst comparing the reach of several cohort combinations without building a report.
  • Quickly checking which workspaces a cohort is available in before activating it.

​
Access

Alpha is a structured technical-validation stage with a small group of design partners, so there is no SLA yet. To request access, or to find out more about how it fits your workflows, contact your Permutive representative. Once you’re granted access, they will provide the connection details and walk you through signing in. The connection acts with your Permutive account, so the tools work with the organizations and workspaces you already have access to.
