# MCP server governance — Use case > Register, authenticate, scope, and audit every MCP server an agent can reach. Apinizer turns the MCP plane into a governed surface — not a wild-west extension layer. *AI teams · MCP · For AI teams* ## Every MCP server registered. Every call authorized. Every action audited. Apinizer's AI Gateway treats the Model Context Protocol surface as a first-class plane. Agents discover only the servers they're scoped to; every invocation passes the same auth and audit as any other API call.

Agents reach for MCP servers the way services used to reach for internal APIs in 2014 — without auth, without scope, without an audit log. The moment an agent can call 'send email' or 'create ticket', the org needs the same governance the API plane took a decade to build. Apinizer's MCP governance applies that decade of work to the new plane on day one. --- ## Capabilities ### MCP server registry Every server registered with capabilities, owners, and scopes. Agents discover only the servers they have permission to use. ### Authenticated invocations Every MCP call carries an identity. OAuth2 / OIDC / JWT — same surface as API calls. No anonymous tool access. ### Scoped permissions An agent might call read_calendar but not write_calendar. Permissions are per tool, per agent, per consumer — and reviewed in the same UI as API permissions. ### Audit at the tool boundary Every MCP invocation captured at the framework boundary. Who, what, when, which tool, which arguments — immutable, queryable, exportable. ### Tool-level rate limits Calls per second, per minute, per day, per agent. A runaway agent can't drain a downstream system. ### Outbound credential vault MCP servers that need external credentials pull them from the platform's encrypted vault — never embedded, never logged, never shared. --- ## Real-world examples ### Banking **Scenario:** Istanbul bank governs 14 MCP servers across the SOC and ops teams **Outcome:** Each server registered with owner, scope, and auth requirement. Agents see only the tools they're scoped to; the SOC sees every invocation. ### Manufacturing **Scenario:** Munich OEM exposes MES tools to factory agents via MCP **Outcome:** MES servers registered with per-line scopes. Line 3 agents cannot read line 4 telemetry; auditors confirm in one query. ### Insurance **Scenario:** Paris insurer enforces PII boundaries on MCP-exposed claim tools **Outcome:** Tools that touch PII require a stricter identity claim. The gateway rejects under-scoped invocations; agents fall back to redacted variants. ### Government **Scenario:** Riyadh ministry rate-limits 'create ticket' to prevent agent storms **Outcome:** Per-agent throttle on ticket creation. A misbehaving prompt loop can't flood ITSM; severity-aware alarm catches the loop in 90 seconds. ### Telecom **Scenario:** Madrid carrier audits every MCP call across 230 agent flows **Outcome:** Audit query returns 'who used tool X in window Y' in seconds. The MCP plane has the same forensic surface as the API plane. ### Media **Scenario:** Milan publisher binds MCP credentials to short-lived JWTs **Outcome:** Agents never hold long-lived secrets. Each invocation carries a per-call token; rotation is automatic. ### Energy **Scenario:** Prague utility separates MCP planes for ops and finance agents **Outcome:** Operations agents discover only operations servers. Finance agents discover only finance servers. Same Manager; different scopes. ### Public sector **Scenario:** Baku ministry adds an MCP server to the existing API portal **Outcome:** The portal lists MCP servers alongside REST APIs. Partners request access to either via the same flow. --- ## Recommended modules - [AI Gateway](https://apinizer.com/products/ai-gateway) — MCP registry, authenticated invocations, scoped permissions, audit at the tool boundary. - [Identity Manager](https://apinizer.com/products/identity-manager) — Agent identities, short-lived tokens, OIDC / JWT — the auth surface MCP needs. - [API Portal](https://apinizer.com/products/api-portal) — Surface MCP servers in the same self-service portal as REST APIs. - [Analytics Engine](https://apinizer.com/products/analytics-engine) — Per-tool, per-agent, per-consumer telemetry — including MCP invocations. --- ## Resources - [MCP governance overview](https://docs.apinizer.com/en) — How Apinizer treats the Model Context Protocol as a governed surface. - [AI Gateway](https://apinizer.com/products/ai-gateway) — The lane MCP traffic runs on — same auth, audit, and scopes as API traffic. - [Registry pattern](https://apinizer.com/products/ai-gateway) — Discovery, scopes, ownership — how the MCP server registry composes. - [Observability & audit](https://apinizer.com/solutions/observability-audit) — How MCP invocations land in the same evidence plane as API calls. - [Agent-to-Agent](https://apinizer.com/solutions/agent-to-agent) — When agents call agents, not just tools — the next layer up. - [Architecture overview](https://docs.apinizer.com/en/concepts/architecture) — Where MCP fits in the AI lane and the broader topology. --- ## Related use cases - [Agent-to-Agent (A2A)](https://apinizer.com/solutions/agent-to-agent) — For AI teams - [Prompt firewalls](https://apinizer.com/solutions/prompt-firewalls) — For AI teams - [AI observability](https://apinizer.com/solutions/ai-observability) — For AI teams - [Three-tier permissions](https://apinizer.com/solutions/three-tier-permissions) — For platform teams --- ## Next step *MCP isn't shadow IT* **Govern the tool layer like you govern the API.** A 30-minute walkthrough — registry, auth, scopes, audit — on a Kubernetes of your choice.
