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 Postiz account to Grok Build through Composio, 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 leaving the terminal. Composio holds the OAuth tokens for you, and Grok Build only calls the tools you approve. ## Also integrate Postiz with - [ChatGPT Work](https://composio.dev/toolkits/postiz_mcp/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/postiz_mcp/framework/antigravity) - [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) - [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) - [Pydantic AI](https://composio.dev/toolkits/postiz_mcp/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/postiz_mcp/framework/autogen) ## TL;DR ### Why use Composio over a standalone MCP server? - Read and write access. Composio's Postiz 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 Postiz 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 Postiz 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 Postiz 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 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, Grok Build can access the Postiz MCP server via Composio to run the app actions you authorize, directly from your terminal. ## Complete Code None listed. ## How to build Postiz MCP Agent with another framework - [ChatGPT Work](https://composio.dev/toolkits/postiz_mcp/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/postiz_mcp/framework/antigravity) - [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) - [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) - [Pydantic AI](https://composio.dev/toolkits/postiz_mcp/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/postiz_mcp/framework/autogen) ## Related Toolkits - [Google Sheets](https://composio.dev/toolkits/googlesheets) - Google Sheets is a cloud-based spreadsheet tool for real-time collaboration and data analysis.

A standalone Postiz MCP server gives Grok Build a fixed set of Postiz tools tied to that one server. The Composio Tool Router lets Grok Build load tools from Postiz 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 Postiz data with Composio? Tokens, keys, and configuration are encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant, so your Postiz data and credentials are handled to that standard. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
