# Impossible Software

> Impossible Software (impossible.io) provides real-time personalized video rendering infrastructure. Videos are rendered on demand from dynamic movie templates and per-viewer data — one unique video per person, generated at the moment of the click. AI agents can build and edit video templates programmatically via the FX Express MCP server, and render videos via the HTTPS Rendering API.

## FX Express MCP Server (for AI agents)

- Endpoint: https://mcp.impossible.io/fxexpress/mcp (Streamable HTTP transport)
- Auth: OAuth 2.1 via https://accounts.impossible.io (resource metadata at https://mcp.impossible.io/.well-known/oauth-protected-resource)
- Purpose: create, edit, compile, and publish video templates (.fxt) — projects, scenes, text/image/video/shape elements, animations and scene-camera keyframes, motion tracking, scene sounds and text-to-speech voiceover, fonts, media uploads, scene and .idm import
- Templates support {variable} placeholders for per-viewer personalization; published templates are rendered via the Rendering API
- Start by calling the get_skill tool (e.g. get_skill("fxhtml-authoring")) for authoring guidance
