Lovable Adds WebMCP Browser-Agent Tools, Gemini 4 Argon Support, and Postgres Extension Limits

Lovable’s October 13, 2026 changelog opens published apps to in-browser AI agents, adds Google’s newly released Gemini 4 Argon model for app AI features, and ships several workspace and database management refinements.

Details

• WebMCP for browser agents: with agent integrations enabled, Lovable adds WebMCP tools so an in-browser AI agent can act on the page a person has open, using their own signed-in session; destructive or payment actions are added only on request
• Gemini 4 Argon model support: Google’s google/gemini-4-argon is now available for an app’s AI features, accepting text, image, audio, and video input at a premium price
• Bulk tool approval for chat connectors: teams can choose to always allow every tool from a chat connector, including tools added later, configurable from Connectors
• Supported PostgreSQL extensions documented: Lovable Cloud supports a fixed set of extensions such as pg_cron, pg_net, vector, and postgis; other CREATE EXTENSION requests are refused and Lovable falls back to plain SQL
• Settings search: the workspace settings sidebar search now finds individual settings and opens them directly

What happened next

Adding WebMCP support is the more consequential item here: it extends Lovable-built apps beyond conversational AI inside Lovable’s own editor, letting external in-browser agents operate the published app itself through a user’s existing session. Paired with same-day support for Gemini 4 Argon — a newly released multimodal model — the update keeps Lovable’s AI feature stack current while nudging published apps toward an agent-operable web, consistent with the broader industry push toward agent-accessible interfaces.
