Create a virtual MCP server
A named, tenant-scoped bundle composing a curated, namespaced subset of tools across several member MCP servers. A native client selects it with the `X-Dvara-Virtual-Server: <name>` header on `/mcp`; `tools/list` returns the allow-listed union and `tools/call` is allow-list-enforced.
Create a webhook
Every delivery carries a `X-Gateway-Signature: sha256=<hex>` header

Promote a shadow policy to active
Transitions a `SHADOW` policy to `ACTIVE`, runs conflict detection, and cleans up shadow event data.
Resolve a pending A2A approval
Approve or deny a paused hop. The decision is written to the durable `a2a_approvals` store and releases the paused hop on its a2a-proxy pod within one poll interval. Emits `A2A_APPROVAL_RESOLVED` on the A2A own-chain.
Revoke an API key
Marks the key as `REVOKED`. The cached entry is evicted on every
Revoke a credential
Marks the credential as `REVOKED`. Subsequent lookups skip it and fall through to the next step in the resolution chain.
Rollback a route
Restores the route to a previous version. Creates a new version with the restored configuration.
Rotate a credential
Replaces the stored API key with a new value, evicts the cached
