Where a tool comes from — the registry-provenance half of classification.

Trust scoping is the security-load-bearing part: taint-immune classification (Capability::FixedConnectorRead) is earned only by operator registration (ToolOrigin::RegisteredConnector / ToolOrigin::FirstParty) — never by a connector’s self-declared annotation hints alone. This is what the MCP specification normatively requires: clients MUST treat tool annotations as untrusted unless the server is trusted.

Variants

LocalSandbox

A sandbox-confined built-in (the coding tools): runs inside the conversation’s execution unit, which has no outbound network.

Fetcher

A built-in fetcher (the web/paid fetchers): brokered on the trusted side to a model-controlled destination.

FirstParty

A built-in that reads or acts on the caller’s own first-party state via the control plane (the history and wallet families): a fixed, operator-owned destination.

AccessGrant

A built-in that grants a third party access to the system itself — the admin invite (#700). Classified apart from Self::FirstParty because it requires Capability::GrantAccess, the never-granted marker, so it always escalates to a human before anything is minted: the agent can only ever PROPOSE an invite, never grant access on its own.

AccessRevoke

A built-in that removes a third party’s access to the system itself — the admin de-admission (#713), the offboarding sibling of Self::AccessGrant. Requires Capability::RevokeAccess, the never-granted marker, so it always escalates to a human before anything is removed: the agent can only ever PROPOSE a removal, never de-admit anyone on its own.

AdminManage

A built-in that takes away a persona’s ADMIN ROLE — the demote tool (#715), the sibling that completes the admin-management set alongside Self::AccessGrant/Self::AccessRevoke. Requires Capability::ManageAdmin, the never-granted marker, so it always escalates to a human before anyone’s admin role changes: the agent can only ever PROPOSE a demote, never remove anyone’s admin role on its own.

RegisteredConnector

A connector tool whose server the operator registered (registry provenance, e.g. the ToolService registry). Its annotations are load-bearing inputs because the operator vouched for the server.

Unknown

Anything else: an unregistered server’s self-declared tool, an unknown name, an unannotated spec. Fails closed to the privileged set.
