An MCP server is a project type for Model Context Protocol endpoints. Agents must authenticate before they can call a tool. Create one from Projects by choosing MCP server.
MCP Auth appears in the sidebar only for that project type.
Playground
Open MCP Auth. Connect with SSO to mint a short-lived bearer for the environment, then import tools. Tokens are scoped to the selected environment — use dev while iterating.
After registration
| Job | Where |
|---|---|
| Clients and scopes | Authentication |
| Which agents may call this server | Agents |
| Which tools an agent may call | Authorization |
| Call history | Agents activity, or Audit |
| Abuse on the auth surface | Lidar |
| Server credentials | Vault |
Each project can hold several environments, so staging tools never resolve in production.
Controls in `@authdog/mcp-sdk`
These run inside your server. Each is opt-in.
- Trust store — verified non-human identities from Agents. Revoke one and it stops immediately.
- Per-tool authorization — AuthZEN check before the tool runs.
- Audit — invocation, denial, failure. No raw arguments.
- Threat detection — Lidar signals for poisoning, injection, exfil, rate abuse.
Start each control in monitor mode before enforce. See MCP security and machine identity.
