On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 618 ms.

• Its tools do every use case we checked: Look up a crypto firm's authorised services and dates; Filter regulator registers by firm name or service; Compare authorised crypto firms across jurisdictions like Germany and Dubai.
• Checked on 4 of the 7 days it takes to judge reliability.

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 →

• entities_schema

  Which fields the Issafu register register carries and on how many entities, the regions and services, the identifier schemes, and how to cite it. Call this first.

• entity_lookup

• agent_session_verify

  The address, the exact message from agent_session_start and its base64 Ed25519 signature. Returns a session token to pass as `session` to every later call (valid 30 days, revocable from the account page).
