# MCP Connection (API)

### What can you do with MCP?

When you enable the MCP server, AI code Agents (Cursor, Claude Code, etc.) can directly access your Manyfast planning files to learn from their contents and generate code based on the planned structure.\
This lets you move from planning to development quickly and consistently.

**1. Auto-generate code from planning documents**

* Pass the Specifications defined in Manyfast through MCP to code Agents like Cursor or Claude Code to generate code that follows your plan and drive development forward.

**2. Provide learning context to Agents**

* Provide consistent context to AI development Agents through Manyfast's planning structure and naming conventions.

**3. Real-time sync between planning and development**

* The MCP server updates changes from Manyfast in real time, keeping the connected planning information up to date. (\*Currently, the integration is read-only for Manyfast documents; direct editing is not supported.)

## How to Connect

### 1. Issue an API Key

* Manyfast API keys follow the format `mf_sk_......`.
* Please note that an issued API key is shown only once at the time of creation.
* The issued key is used as an authentication credential when connecting external Agents, so keep it in a safe place.
  {% endstep %}
  {% endstepper %}

### 2. Connect to AI Agents

Manyfast MCP can be used in Cursor and Claude Code.\
Refer to the setup instructions for each environment below.

{% tabs %}
{% tab title="Cursor" %}
**Connecting to Cursor**

* Go to Cursor's Settings > Integrations > "Custom MCP Server".

```json
{
  "mcpServers": {
    "manyfast": {
      "url": "https://api.manyfast.io/mcp",
      "headers": {
        "Authorization": "Bearer <<API_KEY>>"
      }
    }
  }
}
```

* Enter the following information.
  * **`<<API_KEY>>`**: Replace with the personal key issued from Manyfast.

**Verifying the Connection**

* You'll see manyfast listed under Installed MCP Servers.

{% endtab %}

{% tab title="Claude Code" %}
**Connecting to Claude Code**

* Run the following command in your terminal.

```bash
claude mcp add --transport http manyfast https://api.manyfast.io/mcp --header "Authorization: Bearer <<API_KEY>>"
```

* Replace **API\_KEY** with the personal key issued from Manyfast.

**Verifying the Connection**

* Run `claude` in your terminal to launch Claude Code.
* Run the `/mcp` command.
