# Building with AI

> Use AI-powered tools to integrate Knot's products faster by searching docs from your IDE with the MCP server or installing skills to guide your agent through specific integrations.

## MCP Server

Knot provides an <Tooltip tip="An MCP server is a backend service that implements the Model Context Protocol, which is a standard that allows AI models & agents to interact with tools, data sources, and systems in a structured way.">MCP server</Tooltip> that lets you search and interact with this documentation via natural language from your IDE, terminal, or any MCP-compatible tool. The MCP server searches Knot's documentation only and does not call Knot's API.

### Setup

<Steps>
  <Step title="Install the MCP server">
    Run the following command in your terminal to install the Knot MCP server as a project-level MCP locally. It auto-detects your AI tools (Cursor, Claude Code, VS Code, etc.) and configures them automatically.

    ```bash theme={"system"}
    npx add-mcp https://docs.knotapi.com/mcp --name knot-docs
    ```

    For the Claude Code Desktop App, you may also follow Claude's docs on installing an MCP server [here](https://support.claude.com/en/articles/10949351-getting-started-with-local-mcp-servers-on-claude-desktop).
  </Step>

  <Step title="Begin prompting">
    Ask questions and the agent will search Knot's documentation to retrieve answers directly in your development environment.

    **Example prompts:**

    * "How do I integrate the Knot iOS SDK?"
    * "How can I get the available merchant list for TransactionLink?"
    * "Tell me how to create a session and what do I do after that?"
  </Step>
</Steps>

## Skills

Knot provides product-specific skills that guide AI agents through implementing specific integrations, including the right API calls, webhook handling, data schemas, and testing steps. Installing a skill gives your agent the procedural knowledge to build an integration on your behalf.

<Tip>
  The MCP server helps you *search* Knot's docs. Skills teach your agent *how to build* specific integrations step-by-step.
</Tip>

### Install skills

Run the following command in your terminal to view and select which skills to install into your agent's context so it can take actions on your behalf:

```bash theme={"system"}
npx skills add https://docs.knotapi.com
```

You can also select and copy & paste the skill.md files for relevant skill(s) below to your agent to add skills.
