Official MCP server for PostIdentity that lets you generate AI-powered social media posts from any MCP-enabled assistant. It supports identity management, post generation, and refinements with a credit-based economy. The server offers two deployment options: a Local MCP Server package for on-device assistants (Windsurf, Claude Desktop, etc.) using stdio, and an HTTP MCP Server for cloud-based integrations via a public endpoint. Both transports expose identical functionality and output, making integration seamless regardless of transport. You authenticate with a token or API key, and the system enforces Row Level Security to keep data isolated per user. Features include: managing identities (list, create, archive); generating posts (with optional character limits and refinement options); refining posts (regenerate, shorten, longer, style_adjust, refine) costing 1 credit per refinement; reviewing post history; checking credits; tracking referrals; browsing marketplace templates. The server is ready for local development with Node.js 18+, and there is a migration notice (v2.0) about API keys vs access tokens. It includes usage examples, prerequisites, security notes, and pricing. It is designed for developers and platforms integrating PostIdentity capabilities via MCP.
