MCP control plane

A narrow, typed tool catalog for agents that must propose rather than execute money. The normative catalog contains 53 tools; the listing never implies a permission the caller lacks.

Transport and revision

Modern MCP 2026-07-28 over streamable HTTP is the target, with stdio for local development. The current private implementation still returns an older protocol revision from initialize; treat modern transport as a negotiated capability, not a default.

Rules

Tool annotations are hints; the server enforces.
Destructive tools return a preview or an approval request.
Resources use adbid:// URIs; a URI is a locator, not a credential.
Tasks are durable and re-authorized on cancel or resume.
