FillWise

Overview

FillWise is an MCP server that fills PDF forms with AI using plain text input. It handles fillable PDFs, flat PDFs, USCIS forms, and other official documents, turning unstructured text into accurately populated forms.

The server runs locally via the npm package fillwise-mcp, which communicates over stdio. You'll need to set the FILLWISE_API_KEY environment variable to authenticate. The latest release is v0.1.2, available through npx -y fillwise-mcp.

FillWise appears in the File System category on mcp.site and integrates with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this server, you can claim this listing to verify ownership and keep information accurate.
