Agent tools (WebMCP)
AI agents explore the database through three read-only tools.
WebMCP tools
The app registers three read-only tools on document.modelContext (via the WebMCP polyfill), so AI agents with the MCP-B extension (or Chrome's native support, as it lands) can explore the database alongside you. Every tool also reflects its action in the UI, and SQL errors are returned verbatim from SQLite.
| Tool | Input | Behavior |
|---|---|---|
list_tables | search? | Markdown table of tables + row counts; the sidebar list filters to match. |
view_table | table | Columns, indexes and related tables (foreign keys in both directions); opens the table's Structure tab. |
select_table | sql, page? | Runs SQL with a hard limit of 1000 records per page; returns a markdown table plus total records, total pages and current page; opens the result as a tab. |
