# MCP Hangar

An open-source policy enforcement plane that proxies every MCP tool call through deterministic admission policies, per-server egress rules, and identity-attributed audit trails in Kubernetes.

**Route:** surfaced by the AI Development and Deployment Infrastructure lane's de-branded queries → competitor to vercel.com.

**Why it's on the map:** Sells the same MCP-governance capability to the same platform engineers and AI-agent teams that would shortlist Vercel's AI SDK or AI Gateway for controlling agent-to-tool access.

**Receipts** (verbatim from its page this run):

> The policy enforcement plane for MCP.

> Hangar runs every MCP tool call through one deterministic policy path in Kubernetes: admission policy on each server, per-server egress rules, and an audit trail with identity attribution for every call.

> One proxy between your agents and your MCP servers
