Every team wiring its own MCP servers by hand ends up with credentials scattered across dotfiles and no list of what exists; MCP Gateway and Registry replaces that with one governed front door. Register an MCP server, an A2A agent, a reusable skill, or a custom entity type once, and the Discover page lists it with tags, ratings, and search by natural language. Coding assistants and agents connect to a single authenticated gateway backed by Keycloak, Entra ID, Okta, Auth0, or Cognito, with scopes that decide who may call which tool. Virtual servers bundle tools from several backends behind one endpoint. Connected Accounts brokers third-party logins for Slack, Atlassian, and GitHub so tokens stay off laptops. Every registration is security scanned, and an admission gate holds unsafe items for review. The settings area offers audit log filtering with JSONL and CSV export, federation with outside registries, per-group rate limits, and a searchable configuration viewer. OpenTelemetry metrics and health checks are built in. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.
