FreeScript AI Companion 0.1.0
A screenwriting companion for ChatGPT, Claude web, and Claude Desktop, deployed from this GitHub repository.
ChatGPT and Claude web
MCP URL: https://freescript-ai-companion.onrender.com/mcp
Choose No authentication when adding the custom MCP plugin/connector. Open the setup page for instructions. Platform account and workspace permissions apply.
The hosted tools create formatted screenplay documents from supplied drafts, revise one scene while preserving the rest, analyze scenes and dialogue, and export Fountain, FreeScript JSON, or print-ready HTML. The assistant supplies the creative writing. Compatible MCP Apps hosts can display the classic typewriter preview.
The server is stateless: there is no shared screenplay database or server-side library. It does not expose local filesystem tools. Free hosting can sleep while idle and is subject to provider quotas.
Claude Desktop
Download FreeScript-Claude-0.1.0.mcpb, then install it through Claude Desktop's Extensions settings. Choose a screenplay folder during setup. The local extension adds list/read/save tools, with revision checks before overwrites. This package currently targets macOS and requires Claude's bundled Node runtime to be version 22 or later.
Other downloads
FreeScript-ChatGPT-Plugin-0.1.0.zip is the portable developer/distribution package, including the remote MCP configuration, branding, and a screenwriting skill. ChatGPT personal installation uses the MCP URL above; this ZIP is not a public directory approval or a Mac DMG.
Mac app interoperability
Use Fountain or FreeScript JSON import/export to exchange drafts with the Mac app. The extension folder and Mac app's internal autosave library are separate; live synchronization is not included.
