# Unified > Unified (Unified Enterprise Corp.) is a New York based omnichannel digital advertising company > combining a purpose-built social advertising insights platform with managed campaign services > across paid social, programmatic, OTT and digital audio. It operates a production remote Model > Context Protocol (MCP) server at https://mcp.unified.com/mcp behind its own OAuth authorization > server, and a FastAPI operations service at https://api.unified.com that publishes an OpenAPI > 3.1 description of its root and health endpoints. Provenance: generated 2026-09-02 by the API Evangelist enrichment pipeline from this repository's artifacts and from live probes of unified.com hosts. Unified does not publish an llms.txt of its own (https://www.unified.com/llms.txt, https://api.unified.com/llms.txt and https://mcp.unified.com/llms.txt all return 404), so this file is API Evangelist's third-party description, not a document served by the company. ## What an agent can actually call - [MCP endpoint](https://mcp.unified.com/mcp): the company's agent surface. JSON-RPC 2.0 over HTTP. Requires an OAuth bearer token; an anonymous `tools/list` returns 401 `invalid_token`. The tool set and its input schemas are gated and are not listed anywhere publicly. - [OpenAPI description](https://api.unified.com/openapi.json): OpenAPI 3.1.0, title `unified-mcp-service`, version 0.0.59. Five operations, all anonymous GETs: `root__get`, `health_check_health__get`, `health_check_health_get`, `readiness_check_health_ready_get`, `liveness_check_health_live_get`. No business operation is described. - [Service identity](https://api.unified.com/): returns service name, version, build and environment. - [Health](https://api.unified.com/health), [readiness](https://api.unified.com/health/ready), [liveness](https://api.unified.com/health/live). ## How to authorize - [Authorization server metadata](https://mcp.unified.com/.well-known/oauth-authorization-server) (RFC 8414). Issuer `https://mcp.unified.com/`. - [Protected resource metadata](https://mcp.unified.com/.well-known/oauth-protected-resource/mcp) (RFC 9728). Note the resource-suffixed path — the bare path 404s. - Dynamic client registration at https://mcp.unified.com/register (RFC 7591), authorization_code and refresh_token grants, PKCE `S256` required, bearer token in the Authorization header. - Only one scope is advertised: `openid`. ## Company - [Website](https://www.unified.com/) - [Blog](https://www.unified.com/blog/) - [Customer login](https://get.unified.com/login) - [Terms of use](https://www.unified.com/docs/terms-of-use) - [Privacy policy](https://www.unified.com/docs/privacy-policy) - [GitHub organization](https://github.com/Unified) — nine public repositories, all forks of third-party open source; no first-party SDK. - Contact: hello@unified.com ## What Unified does not publish An agent should know these gaps before planning against Unified: - No public developer portal, quickstart or API reference. `docs.unified.com` returns 200 but redirects into a GitBook single sign-on at `iheartmedia.unified.com/login`. - No `llms.txt`, `security.txt`, `api-catalog`, `ai-plugin.json`, `openid-configuration`, or A2A agent card on any host. - No pricing or plans page; the commercial model is contact-sales. - No status page (the `unified.statuspage.io` subdomain redirects to `/inactive`), no changelog, no roadmap, no deprecation policy, no SLA. - No published rate limits and no rate-limit response headers. - No first-party SDK or CLI on any package registry. - No documented write surface, so idempotency, dry-run and reversibility are all not-applicable on the anonymous surface. ## Repository artifacts (API Evangelist, third-party) - openapi/unified-mcp-service-openapi.json — the provider's spec, saved verbatim - mcp/unified-mcp.yml — MCP server manifest (probed) - mcp/unified-tool-crosswalk.yml — REST/MCP crosswalk; zero mapped, and why - well-known/unified-well-known.yml — full probe matrix with negative controls - authentication/unified-authentication.yml, scopes/unified-scopes.yml - errors/unified-problem-types.yml, conventions/unified-conventions.yml - conformance/unified-conformance.yml, lifecycle/unified-lifecycle.yml - data-model/unified-data-model.yml, rate-limits/unified-rate-limits.yml - plans/unified-plans-pricing.yml, packages/unified-packages.yml - security/unified-domain-security.yml - skills/unified-connect-mcp.md
