Metadata
Metadata (metadata.io) is a B2B marketing automation and demand-generation platform that uses AI agents to plan, execute, and optimize paid advertising campaigns across LinkedIn, Meta (Facebook and Instagram), Google Search and Display, Reddit, and Bing. Its core products are Metadata Campaigns (automated full-funnel paid campaign execution), Metadata Audiences with the patented MetaMatch B2B audience engine for precision targeting, and Metadata Insights for real-time, revenue-focused performance analytics. The platform connects to ad channels, CRMs (Salesforce, HubSpot), and marketing automation platforms (Marketo, Pardot) to run multivariate campaign testing at scale and optimize for pipeline and revenue rather than lead volume. Backed by 500 Global and Partech. Metadata publishes no public REST API. Its developer surface is MCP-native: the MetadataONE MCP server at mcp-server.metadata.io/mcp exposes 141 documented tools across audiences, campaigns, creatives, offers, keywords, ad extensions, analytics and integrations, so an agent can build an audience, generate on-brand creative, assemble a campaign and launch real paid spend without a REST client or an SDK. Developer docs, a quickstart, an authentication and scopes reference and the full tool catalog are published at metadata.io/developers/.
Metadata publishes 2 APIs on the APIs.io network: Health API and MCP API. Tagged areas include Company, Marketing, Marketing Automation, Demand Generation, and Advertising.
Metadata’s developer surface includes support, engineering blog, pricing, documentation, API reference, getting-started guide, and 14 more developer resources.
