# Introduction

> Connect Radarkit to ChatGPT, Claude, Cursor or Codex and ask questions in plain language.

MCP is a standard that lets an AI client call tools on a server. The Radarkit MCP server offers the whole API as tools. You connect it once, then ask questions. The client picks the tool, calls it with your key and reads the result.

```text theme={"system"}
https://api.radarkit.ai/mcp
```

## Three steps

<Steps>
  <Step title="Add the server to your client">
    <a className="rk-button rk-button--secondary" href="/docs/mcp/setup">Go to Setup</a>

    One URL, or one click, depending on the client.
  </Step>

  <Step title="Sign in">
    The client opens a Radarkit page. Tick what it may do and click Allow. No key to paste.
  </Step>

  <Step title="Ask">
    ```text theme={"system"}
    How visible was Acme in AI answers over the last 7 days, per model?
    ```

    Claude calls `get_visibility` and summarises the result.
  </Step>
</Steps>

## What it can do

<CardGroup cols={3}>
  <Card title="Read" icon="eye">
    17 tools for projects, topics, prompts, visibility, responses, sources, share of voice, rankings, query fanout, sentiment and exports.
  </Card>

  <Card title="Write" icon="pen">
    4 tools to add topics and prompts, run a prompt now and create exports.
  </Card>

  <Card title="Agents" icon="wand-magic-sparkles">
    3 tools to write, check and retry articles with the Content agent.
  </Card>
</CardGroup>

A key only sees the tools its permissions allow. The full list with arguments is on the [Tools](/docs/mcp/tools) page.

## Good to know

* Signing in creates a key for that app on your keys page. Disconnect it there at any time.
* A tool call costs exactly what the matching REST call costs. Every result includes `credits.charged` and `credits.remaining`. Connecting and listing tools is free.
* List tools return at most {limits.mcpRowsPerCall} rows per call so answers stay readable. For bulk data the client will offer to create an export.
* Answer text is Markdown, cut to {limits.mcpAnswerChars} characters by default. A marker at the end says how much was cut.
* Tools that spend realtime or content credits ask you to confirm before running.
