InterfaceDelta

InterfaceDelta keeps an independent, versioned record of the services AI agents connect to, starting with MCP servers listed in the Official MCP Registry. It observes each service from the outside, the way an agent would before using it, and records what the service declares: its tools and their inputs, protocol details, and every change since. Each new observation is compared with the last, and breaking changes (a tool removed, an input made required) are flagged. With this connector, Claude can search the atlas, open any service's entry, and read its Passport: the tool inventory, change history, breaking changes, and AI readings of what each tool can do (for example "reads only", "sends messages", "moves money"), marked as AI with a confidence score. Everything is read-only. The connector never calls the services it describes and needs no account. InterfaceDelta publishes facts, not scores: no rankings, no "safe" verdicts, no paid placement.
