MANDATE Credential Broker is a remote MCP server that gives an AI agent 11 tools, among them broker.introspect-grant, broker.register-credential, broker.request-access. It answers at https://mandate.nanocorp.app/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 23 October 2026, succeeded.
MCP server for mandates, delegation, policy-gated execution, credential grants, and audit.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
broker.introspect-grant | Validates a grant token seal, reports active/revoked/expired state, and records introspection to the ledger. |
broker.register-credential | Registers an opaque vault handle/reference only; plaintext secret fields are rejected and never ledgered. Inputs: vault_handle, metadata |
broker.request-access | Asks the canonical Policy Engine for an ALLOW decision before issuing a short-lived HMAC-sealed grant bound to credential, mandate, agent, scope, and expiry. |
broker.revoke-grant | Revokes a broker grant by id and records the revocation to the ledger. |
broker.use | Redeems a sealed grant for the bound acting agent and executes the bound action through the Gateway and Policy Engine; does not expose plaintext secrets. |
mandate.authorize-action | Submits an action through the Gateway and canonical Policy Engine; returns ALLOW, DENY, or REQUIRE_APPROVAL with ledger proof. |
mandate.delegate | Creates a child mandate only when it is a no-escalation subset of the parent mandate. |
mandate.discover | Returns this self-describing tool manifest. |
mandate.mint | Creates an active human-granted mandate for an agent and records it to the hash-chained ledger. |
mandate.revoke | Revokes a mandate subtree and records the revocation to the hash-chained ledger. |
mandate.verify-proof | Records a proof payload hash and appends proof evidence to the hash-chained ledger. |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mandate.nanocorp.app/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
