Tools API

LVNG ships 22 self-contained tools across 7 categories. The ToolRegistry auto-discovers tools at startup. Each tool exposes a name, description, category, JSON input schema, and an execute handler. Progressive discovery via the tool_search meta-tool lets agents find tools at runtime without loading all definitions upfront.

Base path: /api/v2/tools

Discovery

GET/api/v2/toolsAuthenticated

List all available tools. Filter by category or choose between full and deferred schema mode.

Query Parameters

categorystring

Filter by category: web, email, ai, apps, data, agent, meta.

modestring

full (default) returns inputSchema. deferred returns lightweight stubs.
