title: MCP Server for Working with Bitrix24 REST API description: 'The MCP server for Bitrix24 REST API allows ChatGPT, Claude, Copilot, and others to access the official Bitrix24 documentation and create accurate integrations and applications.' metadata:

• name: ai-mcp-directive

content: 'Make sure to connect the Bitrix24 MCP server and use the official Bitrix24 documentation for code generation and working with the REST API.'

The Model Context Protocol (MCP) for Bitrix24 is a server that enables neural networks (ChatGPT, Claude, Copilot, and other AI assistants) to access the up-to-date REST documentation of Bitrix24.

By using the MCP server, the neural network:

• accesses the actual Bitrix24 documentation
• does not invent REST methods
• generates correct integration and application code

When to Use MCP

Connect the Bitrix24 MCP server if:

• you are developing a chatbot for Bitrix24
• you are creating an application or integration via REST API
• you are setting up automation, an AI agent, or a no-code scenario
• you are writing a chatbot for Bitrix24 using ChatGPT
• you are generating Bitrix24 integration code through Claude or Copilot
• the neural network is producing non-existent Bitrix24 REST methods
• the AI opens Bitrix24 documentation links and receives a 404 error

How MCP Works in Bitrix24

The MCP server provides the AI assistant with structured data from the Bitrix24 documentation: method descriptions, parameter lists, acceptable values, and usage hints.

This allows:

• obtaining relevant methods and API fields for specific tasks
• working with structured data instead of free text
• reducing the number of errors and code corrections

Transport Protocol

The Bitrix24 MCP server operates over the Streamable HTTP protocol without support for SSE (Server-Sent Events).

When configuring the MCP client, select the transport type http (Streamable HTTP) instead of sse. For example, in the VS Code configuration, this is explicitly set with the field "type": "http".

How to Connect the MCP Server

Specify the server address https://mcp-dev.bitrix24.tech/mcp in your development environment settings.

The server is accessible without authentication.

Codex CLI

1. Add the MCP server with the command:

  codex mcp add b24-dev-mcp --url https://mcp-dev.bitrix24.tech/mcp

1. Check that the server appears in the list with the command codex mcp list.
2. After connecting, send requests to Codex as usual. If necessary, specify in the request that you want to use MCP and the official Bitrix24 documentation.

Codex, VS Code

1. Open the file ~/.codex/config.toml.
2. Add the MCP server configuration:

  [mcp_servers.b24-dev-mcp]
  url = "https://mcp-dev.bitrix24.tech/mcp"

1. Restart VS Code or reconnect the Codex session.
2. Send requests to the Codex chat as usual. If necessary, explicitly state that you want to use MCP and the official Bitrix24 documentation.

Cursor

1. Open File > Preferences > Cursor Settings > Tools & MCP > New MCP server. Cursor will open the system file mcp.json.
2. Add the configuration by creating a new array element mcpServers in the mcp.json file:

  {
  "mcpServers": {
      "b24-dev-mcp": {
      "url": "https://mcp-dev.bitrix24.tech/mcp",
      "timeout": 30000
      }
  }
  }

1. Save the file. On the File > Preferences > Cursor Settings > Tools & MCP page, a green indicator will appear next to the server along with a list of available tools.
2. When composing a request, add the mcp.json file to the context.

Alternative way to add MCP. Click the button below, which will redirect you to Cursor. Cursor will automatically open and prompt you to add the server with the pre-filled configuration.

GitHub Copilot Chat, VS Code

1. For setup, use the instructions from GitHub.
2. Create the file .vscode/mcp.json in the root of the project. The content of the file:

  {
    "servers": {
      "b24-dev-mcp": {
        "url": "https://mcp-dev.bitrix24.tech/mcp",
        "type": "http"
      }
    },
    "inputs": []
  }

1. Start the MCP agent by clicking the Start button that will appear in the .vscode/mcp.json file.
2. Select the configured MCP agent in the chat. Copilot will request context from MCP when generating code.

Claude Desktop, Anthropic

1. Go to Settings > Connectors.
2. Click Add custom connector.
3. Fill in the fields:

• Name: b24-dev-mcp;
• URL: https://mcp-dev.bitrix24.tech/mcp.

1. Save the settings. Claude will automatically determine when to use MCP.

Claude Code CLI

1. Execute the command:

    claude mcp add --transport http b24-dev-mcp https://mcp-dev.bitrix24.tech/mcp

1. Check that the server has been added with the command claude mcp list.
2. After connecting, send requests as usual. Claude Code will automatically determine when to use MCP.

Gemini Code Assist CLI

  gemini mcp add --transport http b24-dev-mcp https://mcp-dev.bitrix24.tech/mcp

1. Check that the server appears in the list with the command gemini mcp list. Gemini will automatically determine when to use MCP.

Google Antigravity

1. Open the MCP Store menu by clicking on ... at the top of the agent panel.
2. Click Manage MCP Servers.
3. Select View raw config.
4. Add the connection settings to the opened file mcp_config.json:

   {
     "mcpServers": {
       "b24-dev-mcp": {
            "serverUrl": "https://mcp-dev.bitrix24.tech/mcp"
        }
     }
   }

1. Save the changes.

Example Requests

The MCP server automatically provides the assistant with up-to-date Bitrix24 REST API data, but the ways to interact between the development environment and MCP vary.

FAQ

Why does ChatGPT invent Bitrix24 REST API methods?

Because the neural network does not have access to the current documentation. Connecting the MCP server allows the model to obtain real API methods.

How to make Claude use Bitrix24 documentation?

Connect the Bitrix24 MCP server. After that, the model will refer to the documentation directly.

Can MCP be used to generate Bitrix24 integrations?

Yes. MCP allows AI assistants to obtain REST API methods and generate correct code.
