The server supports both hosted OAuth and local API-key setups, offering tools for account management, post scheduling, media upload, and analytics.", "body_md": "MCP server for the [PostFast](https://postfa.st) API — schedule and manage social media posts via AI tools like Claude, Cursor, VS Code, and more.\n\nPrefer not to run anything locally? Connect to the hosted endpoint and authenticate with OAuth — no npx, no API key to manage:\n\n```\nhttps://mcp.postfa.st/mcp\n```\n\nAdd it as a remote/streamable-HTTP MCP server in any client that supports OAuth (e.g. ChatGPT, Claude). You'll be prompted to sign in to PostFast and authorize access on first use.\n\nWant to run the server yourself instead? Use the npx + API-key setup in **Quick Start** below.\n\nLog in to [PostFast](https://app.postfa.st/dashboard), go to **API** in the sidebar, and generate a key.\n\nChoose your preferred method:\n\nDownload the extension from the [Claude Desktop extension directory](https://claude.ai/extensions) or install manually:\n\n- Add to\n`claude_desktop_config.json`\n\n:\n\n```\n{\n  \"mcpServers\": {\n    \"postfast\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"postfast-mcp\"],\n      \"env\": {\n        \"POSTFAST_API_KEY\": \"your-api-key-here\"\n      }\n    }\n  }\n}\n```\n\n- Restart Claude Desktop.\n\n**Via plugin (pending marketplace approval):**\n\n```\n/plugin install postfast@claude-plugins-official\n```\n\nAfter installing, set your API key — pick one of these:\n\n```\n# Option A: Add to your shell profile (~/.zshrc or ~/.bashrc)\nexport POSTFAST_API_KEY=\"your-api-key-here\"\n\n# Option B: Add to ~/.claude/settings.local.json\n# { \"env\": { \"POSTFAST_API_KEY\": \"your-api-key-here\" } }\n```\n\nThen restart Claude Code.\n\n**Via manual config:**\n\nAdd to your project's `.mcp.json`\n\nor `~/.claude/.mcp.json`\n\n(global):\n\n```\n{\n  \"mcpServers\": {\n    \"postfast\": {\n      \"type\": \"stdio\",\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"postfast-mcp\"],\n      \"env\": {\n        \"POSTFAST_API_KEY\": \"your-api-key-here\"\n      }\n    }\n  }\n}\n```\n\nAdd to your MCP config (`.mcp.json`\n\n, `mcp.json`\n\n, or the tool's settings UI):\n\n```\n{\n  \"mcpServers\": {\n    \"postfast\": {\n      \"type\": \"stdio\",\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"postfast-mcp\"],\n      \"env\": {\n        \"POSTFAST_API_KEY\": \"your-api-key-here\"\n      }\n    }\n  }\n}\n```\n\nAsk your AI assistant things like:\n\n- \"List my connected social accounts\"\n- \"Schedule a post to Instagram for tomorrow at 9am\"\n- \"Show me all scheduled posts for this week\"\n- \"Upload this image and create a LinkedIn post with it\"\n- \"Create a Facebook reel with this video\"\n- \"Show me analytics for my Instagram posts this month\"\n\n| Tool | Description
