Skip to main content
The contextual toolbar is a floating action bar that appears on every page of your docs. It lets readers instantly copy page content, open it in an AI assistant, or add your docs as an MCP server — without leaving the page. Configure it in docs.json under contextual.options:
docs.json

MCP

The mcp and add-mcp options are especially powerful — they let developers connect your entire docs site to any MCP-compatible AI assistant, so it can answer questions about your product directly.

Custom options

You can add custom entries to the toolbar with a title, description, icon, and link. The href supports dynamic placeholders:
docs.json
The contextual toolbar is only visible on preview and production deployments, not in mint dev local preview.

Pairing with Visibility

The toolbar’s copy and view options expose your page’s Markdown content directly. If you use the Visibility component, the for="agents" blocks will be included in that Markdown — giving AI assistants structured context that human readers don’t see.
