It treats the AI agent as a first-class teammate, planning, coding, and validating work through an Agent Manager dashboard with deep browser connectivity. In this guide, I will explain the easiest and most secure way to connect your Anthropic administrator account to Antigravity IDE via Composio Connect, so it can list all available Anthropic models, get details for a specific Anthropic model, cache a frequently used prompt template, and more without ever putting your account credentials at risk. ## Also integrate Anthropic administrator with - [Claude Code](https://composio.dev/toolkits/anthropic_administrator/framework/claude-code) - [Cursor](https://composio.dev/toolkits/anthropic_administrator/framework/cursor) - [ChatGPT](https://composio.dev/toolkits/anthropic_administrator/framework/chatgpt) - [Claude Cowork](https://composio.dev/toolkits/anthropic_administrator/framework/claude-cowork) - [OpenAI Agents SDK](https://composio.dev/toolkits/anthropic_administrator/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/anthropic_administrator/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/anthropic_administrator/framework/codex) - [Grok Build](https://composio.dev/toolkits/anthropic_administrator/framework/grok-build) - [VS Code](https://composio.dev/toolkits/anthropic_administrator/framework/vscode) - [OpenCode](https://composio.dev/toolkits/anthropic_administrator/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/anthropic_administrator/framework/openclaw) - [Hermes](https://composio.dev/toolkits/anthropic_administrator/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/anthropic_administrator/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/anthropic_administrator/framework/google-adk) - [LangChain](https://composio.dev/toolkits/anthropic_administrator/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/anthropic_administrator/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/anthropic_administrator/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/anthropic_administrator/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/anthropic_administrator/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/anthropic_administrator/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/anthropic_administrator/framework/autogen) ## TL;DR ### Why use Composio? Composio provides: - Access to 1,500+ managed apps from a single MCP endpoint. This makes it convenient for agents to run cross-app workflows. - Programmatic tool calling. Allows LLMs to write code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool response handling outside the LLM context. This minimizes context bloat from large tool responses. - Dynamic just-in-time access to thousands of tools across hundreds of apps. Composio loads the tools your agent needs, so LLMs are not overwhelmed by tools they do not need. ## Connect Anthropic administrator to Antigravity ### Connect Anthropic administrator to Antigravity Antigravity does not ship with one-click custom MCP install links yet, so configuration goes through the IDE's raw config file. The process takes under a minute. ### 1. Open the MCP Config Go to Antigravity Settings, open the Customizations tab, then click Open MCP Config to open mcp_config.json in the editor. ### 2. Get your API key Go to the [Composio Dashboard](https://dashboard.composio.dev/~/org/connect/clients/) and copy your API key. ### 3. Add Composio to mcp_config.json Paste the following configuration into the file: ```bash { "mcpServers": { "remote-composio": { "serverUrl": "https://connect.composio.dev/mcp", "headers": { "x-consumer-api-key": "your-composio-api-key" } } } } ``` ## 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 available Claude models and message completions, so your agent can browse models, inspect model details, select a suitable model, and create Claude message completions on your behalf. - Available model discovery: Have your agent list the Claude models currently available for your tasks. - Model detail retrieval: Direct your agent to retrieve information about a specific Claude model. - Model comparison: Let the agent review available models and their details to help you choose one for your use case. - Claude message creation: Instruct your agent to send a prompt to Claude and generate a message completion. ## 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 Once connected, Antigravity can access the Anthropic administrator MCP server via Composio to run actions that you authorize directly from the agent panel. ## Complete Code None listed. ## Conclusion ### Conclusion You have successfully connected Anthropic administrator to Antigravity using Composio Connect. Your agent can now use Anthropic administrator securely without exposing credentials in prompts or local scripts. ## How to build Anthropic administrator MCP Agent with another framework - [Claude Code](https://composio.dev/toolkits/anthropic_administrator/framework/claude-code) - [Cursor](https://composio.dev/toolkits/anthropic_administrator/framework/cursor) - [ChatGPT](https://composio.dev/toolkits/anthropic_administrator/framework/chatgpt) - [Claude Cowork](https://composio.dev/toolkits/anthropic_administrator/framework/claude-cowork) - [OpenAI Agents SDK](https://composio.dev/toolkits/anthropic_administrator/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/anthropic_administrator/framework/claude-agents-sdk) - [Codex](https://composio.dev/toolkits/anthropic_administrator/framework/codex) - [Grok Build](https://composio.dev/toolkits/anthropic_administrator/framework/grok-build) - [VS Code](https://composio.dev/toolkits/anthropic_administrator/framework/vscode) - [OpenCode](https://composio.dev/toolkits/anthropic_administrator/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/anthropic_administrator/framework/openclaw) - [Hermes](https://composio.dev/toolkits/anthropic_administrator/framework/hermes-agent) - [Atomic Agent](https://composio.dev/toolkits/anthropic_administrator/framework/atomic-agent) - [Google ADK](https://composio.dev/toolkits/anthropic_administrator/framework/google-adk) - [LangChain](https://composio.dev/toolkits/anthropic_administrator/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/anthropic_administrator/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/anthropic_administrator/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/anthropic_administrator/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/anthropic_administrator/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/anthropic_administrator/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/anthropic_administrator/framework/autogen) ## Related Toolkits - [Composio](https://composio.dev/toolkits/composio) - Composio is an integration platform that connects AI agents with hundreds of business tools.
