MCP Server

Let AI agents compare documents through Differino. Works with Claude, Cursor, and any MCP-compatible client.

What is MCP?

The Model Context Protocol is a standard for AI agents to use external tools. Differino's MCP server lets agents upload and compare documents programmatically — no browser needed. Your AI assistant can compare contracts, review document changes, and summarize differences on its own.

bash

pnpm add -g differino-mcp

Response Contract

Comparison responses include a text summary and, when available, visual artifact metadata for page renders and highlighted regions.

visual.statusOne of ready, pending, missing, or disabled.

visual.manifestPage image URLs, red/green highlighted regions, grouped change identities, and salience metadata when visual.status is ready.

regions[].groupIdStable identity for paired fragments, including modifications that cross page boundaries.

regions[].salienceIndicates subtle, visible, structural, or technical changes so clients can surface hard-to-see differences.

visual.diffUrlSigned URL for the visual diff JSON when available.

If visual.status is not ready, use the text diff summary and full comparison URL instead of treating the visual result as no changes.
