Metadata extends its Bid Agent to all LinkedIn campaigns and adds Reddit ads via MCP

Metadata.io published eight features and seven fixes on April 23, 2026. AI-related changes cover the Bid Agent, which now reads suggested bids across every LinkedIn campaign, and the MCP server, which can now create Reddit ads. The HubSpot integration was updated to current API standards ahead of HubSpot's sunset of its Contact Lists API v1. Audience targeting changes add Facebook city targeting and Reddit MAID matching, and search terms export is now enabled by default.

The details

• Bid Agent suggested bid extraction covers all LinkedIn campaigns.
• Reddit ad creation is supported through Metadata's MCP server.
• HubSpot is discontinuing its Contact Lists API v1, according to the release notes.
• Reddit custom audiences now sync mobile advertising IDs alongside hashed emails.
