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 1 API on the APIs.io network: MCP Server (MetadataONE). 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 11 more developer resources.

description: 'The MetadataONE Model Context Protocol server — Metadata''s only public developer surface. 141 documented
tools let an MCP client (Claude Code, Claude Desktop, Hermes, Paperclip, OpenClaw or a custom agent) run B2B paid media
end to end: build firmographic, technographic, Bombora-intent, G2-intent, native-criteria, retargeting and CSV-uploaded
audiences; extract brand kits and generate on-brand image, video, carousel, document and conversation ads; create lead-gen
and landing-page offers; assemble Precision (1x1x1) or Channel-First (NxNxN) campaigns inside a budget group; launch them
to real spend on LinkedIn, Meta, Google, Microsoft and Reddit; manage keywords and Google/Microsoft ad extensions; and
read funnel, experiment, ABM and pipeline analytics. Authentication is a bearer API key (md1_live_ prefix) scoped to a
single account, with seven product permission scopes that separate read, draft and launch. The endpoint also serves RFC
8414 authorization-server and RFC 9728 protected-resource metadata anonymously, so an OAuth-capable client can discover
it without credentials. Campaigns are created in Draft and only launch_campaign moves real budget.'
