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 Postiz account to Antigravity IDE via Composio Connect, so it can schedule a LinkedIn post for next Monday, get analytics for your last Facebook post, list all scheduled posts for this week, and more without ever putting your account credentials at risk. ## Also integrate Postiz with - [ChatGPT](https://composio.dev/toolkits/postiz_mcp/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/postiz_mcp/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/postiz_mcp/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/postiz_mcp/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/postiz_mcp/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/postiz_mcp/framework/codex) - [Cursor](https://composio.dev/toolkits/postiz_mcp/framework/cursor) - [VS Code](https://composio.dev/toolkits/postiz_mcp/framework/vscode) - [OpenCode](https://composio.dev/toolkits/postiz_mcp/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/postiz_mcp/framework/openclaw) - [Hermes](https://composio.dev/toolkits/postiz_mcp/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/postiz_mcp/framework/cli) - [Google ADK](https://composio.dev/toolkits/postiz_mcp/framework/google-adk) - [LangChain](https://composio.dev/toolkits/postiz_mcp/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/postiz_mcp/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/postiz_mcp/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/postiz_mcp/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/postiz_mcp/framework/crew-ai) ## TL;DR ### Why use Composio? Composio provides: - Access to 1,000+ 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 Postiz to Antigravity ### Connect Postiz 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 Postiz MCP server, and what's possible with it? The Postiz MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Postiz account. It provides structured and secure access so your agent can perform Postiz operations on your behalf. ## Supported Tools None listed. ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK Once connected, Antigravity can access the Postiz 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 Postiz to Antigravity using Composio Connect. Your agent can now use Postiz securely without exposing credentials in prompts or local scripts. ## How to build Postiz MCP Agent with another framework - [ChatGPT](https://composio.dev/toolkits/postiz_mcp/framework/chatgpt) - [OpenAI Agents SDK](https://composio.dev/toolkits/postiz_mcp/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/postiz_mcp/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/postiz_mcp/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/postiz_mcp/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/postiz_mcp/framework/codex) - [Cursor](https://composio.dev/toolkits/postiz_mcp/framework/cursor) - [VS Code](https://composio.dev/toolkits/postiz_mcp/framework/vscode) - [OpenCode](https://composio.dev/toolkits/postiz_mcp/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/postiz_mcp/framework/openclaw) - [Hermes](https://composio.dev/toolkits/postiz_mcp/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/postiz_mcp/framework/cli) - [Google ADK](https://composio.dev/toolkits/postiz_mcp/framework/google-adk) - [LangChain](https://composio.dev/toolkits/postiz_mcp/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/postiz_mcp/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/postiz_mcp/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/postiz_mcp/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/postiz_mcp/framework/crew-ai) ## Related Toolkits - [Google Sheets](https://composio.dev/toolkits/googlesheets) - Google Sheets is a cloud-based spreadsheet tool for real-time collaboration and data analysis.

With a standalone Postiz MCP server, the agents and LLMs can only access a fixed set of Postiz tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Postiz and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Antigravity? Yes, you can. Antigravity fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Postiz tools. ### Can I manage the permissions and scopes for Postiz while using Tool Router? Yes, absolutely. You can configure which Postiz scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Postiz data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
