## Introduction

### How to integrate Anthropic administrator MCP with Grok Build
[Grok Build](https://docs.x.ai/build/overview) is xAI's terminal coding agent. It runs on Grok 4.5, plans its work before it acts, and can run multiple sub-agents in parallel. It also reads Claude Code's MCP configuration, so any server you already have in a .mcp.json is picked up with no changes.
In this guide, I will show you how to connect your Anthropic administrator account to Grok Build through Composio, so it can list all available Anthropic models, get details for a specific Anthropic model, cache a frequently used prompt template, and more without leaving the terminal. Composio holds the OAuth tokens for you, and Grok Build only calls the tools you approve.

## TL;DR

### Why use Composio over a standalone MCP server?
- Read and write access. Composio's Anthropic administrator integration lets Grok Build take real actions like creating drafts, sending updates, and labeling records, not just reading data.
- 1,000+ SaaS toolkits out of the box. One endpoint gives you a full catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
- One MCP server for every app. Wire up a single Composio server instead of maintaining a separate MCP entry for each app.
- Smart, context-aware tool loading. Grok Build caps how many tools it holds in a single request. Composio loads only the tools a task needs, so you do not spend that budget on tools you are not using.
- Cross-app automation. Chain actions across apps in one run. Pull a thread, summarize it in Notion, and post the highlights to Slack from a single prompt.

## Connect Anthropic administrator to Grok Build

### Prerequisites
- Grok Build installed and signed in. Install with curl -fsSL https://x.ai/cli/install.sh | bash on macOS or Linux, or irm https://x.ai/cli/install.ps1 | iex on Windows PowerShell. On first launch Grok opens a browser to authenticate; for headless or CI use, set an XAI_API_KEY environment variable instead (create the key at [console.x.ai](https://console.x.ai/)).
- Access to the Anthropic administrator account you want to connect.
- The [Composio MCP endpoint](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=grok-build&utm_content=composio_connect). Composio's server is remote and hosted, so there is nothing to run locally and no tunnel to set up.
### Step-by-step: Connect Anthropic administrator to Grok Build
### 1. Install and verify Grok Build
Install the CLI, then restart your shell so the grok binary lands on your PATH:

```bash
curl -fsSL https://x.ai/cli/install.sh | bash
which grok
```

## What is the Anthropic administrator MCP server, and what's possible with it?

The Anthropic administrator MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Anthropic administrator account. It provides structured and secure access to your Anthropic organization, so your agent can perform actions like generating model completions, managing models, retrieving model details, and optimizing prompt usage on your behalf.
- Seamless message and completion creation: Instruct your agent to generate assistant responses or create message completions within conversation workflows, tailored to your organizational needs.
- Comprehensive model listing and management: Have your agent fetch a full list of available Anthropic models, making it easy to discover and select the right model for any use case.
- Detailed model information retrieval: Let your agent pull specific details about any Anthropic model by its ID, ensuring you always have the latest information on capabilities and configurations.
- Efficient prompt caching and reuse: Enable your agent to store and reuse portions of prompts, reducing both operational costs and latency for high-frequency or repetitive tasks.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `ANTHROPIC_ADMINISTRATOR_CREATE_MESSAGE` | Create Message | Create a message completion from Claude. Send a conversation history with user/assistant messages and receive Claude's response. Useful for: chatbots, Q&A systems, text generation, conversational AI, and any task requiring natural language understanding or generation. |
| `ANTHROPIC_ADMINISTRATOR_GET_MODEL` | Get Model | Tool to retrieve details of a specific model by its ID. Use after confirming the model ID is valid. |
| `ANTHROPIC_ADMINISTRATOR_LIST_MODELS` | List models | Tool to list available models. Use when you need to see which models are available before selection. Always source model IDs from this tool rather than hard-coding them; stale or outdated model IDs passed to CREATE_MESSAGE will cause a not_found_error. |

## Supported Triggers

None listed.

## Creating MCP Server - Stand-alone vs Composio SDK

## Frequently Asked Questions

### What is the difference between the Composio Tool Router and a standalone Anthropic administrator MCP server?

A standalone Anthropic administrator MCP server gives Grok Build a fixed set of Anthropic administrator tools tied to that one server. The Composio Tool Router lets Grok Build load tools from Anthropic administrator and many other apps on demand, based on the task, all through a single endpoint.

### Does Grok Build support MCP?

Yes. Grok Build ships with native MCP support. Add a server with the grok mcp add command, from the in-session /mcps modal, or by editing ~/.grok/config.toml. It also reads Claude Code-style .mcp.json files, so Grok Build discovers the tools automatically.

### Can I reuse the same MCP config I already use with Claude Code?

Yes. Grok Build has zero-migration compatibility with Claude Code's configuration, so the same Composio server entry works in both without edits.

### How safe is my Anthropic administrator data with Composio?

Tokens, keys, and configuration are encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant, so your Anthropic administrator data and credentials are handled to that standard.
