• Registry nameai.decisionlog/mcpverified in the MCP registry

The registry name sits under decisionlog.ai. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-21 the server answered initialize and tools/list without a sign-in. First answer in 134 ms.

• Its tools do every use case we checked: Find the active decision and its replacement history; Trace the rationale and sources behind an earlier choice.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  Search decisions in the authenticated workspace.

• decision_log_get_decision

  Retrieve one decision by ID.

• decision_log_supersede_decision

  Create a replacement Decision and supersession relationship for an existing Decision.
