kandev/apps/web/lib/settings/external-mcp-tools.ts

// Static catalog of MCP tools exposed by the Kandev backend's external endpoint.
// Mirrors apps/backend/internal/mcp/server (ModeExternal). Keep in sync when
// tools are added, removed, or renamed.
//
// KNOWN DRIFT: `ModeExternal` registers 32 tools, this lists 29 —
// `list_repositories_kandev`, `import_workflow_kandev` and one task tool are
// missing, so the settings page under-advertises the endpoint. See the note in
// `external-mcp-tools.test.ts`.
//
// The `name`s are the protocol identifiers an external agent calls, so they stay
// literal in every locale. Only the group titles and the human descriptions are
// copy, and they travel as catalog keys resolved at render — this module is
// evaluated at import, so a `t()` here would freeze at the boot locale.
