📝 Walkthrough

Walkthrough

This pull request adds two new documentation pages to the MI docs site: a guide for creating an MCP Server artifact and a reference page for MCP inbound endpoint properties. The MCP server guide covers artifact creation, tool addition from APIs/sequences, configuration updates, and example source XML. The reference page documents the inbound endpoint's configuration properties, syntax, and tool definition schema. Corresponding navigation entries were added to mkdocs.yml.

A rabbit hops through docs anew,
MCP tools now in full view,
Servers built with ports and CORS,
Sequences mapped, no missing source,
Nav links added, clean and true —
Hop along, the guide's for you!
