Um programa verifica o servidor uma vez por dia: initialize e tools/list, sem modelo. Os tokens são o tamanho das definições, a cerca de quatro caracteres por token. A nota é a média de seis verificações do nome, da descrição, do esquema e das anotações de cada ferramenta; diz se as ferramentas estão bem descritas, não se funcionam. A nota pesa só o que foi medido: se responde (25%), se faz o trabalho do produto (25%), definições (20%), contexto (10%), uso (10%) e a facilidade de conectar (10%). Uma parte não medida fica de fora, e uma instrução oculta limita a nota a 40. O estado dos servidores MCP dos fornecedores: método e números →

• get_key

  Get a FlexYield API key with no signup: public supply, 10,000 weighted units per UTC day, 5 requests/s, every tool. Use it once, when you have no key yet; then send the key as the bearer on every other call. Not for a key you already hold…

• bind_key_start

• bind_key_complete

  Step 2 of binding the API key you are calling with to a wallet: pass the wallet's signature over the message from bind_key_start. Use it right after bind_key_start, with the same key. Not for the first step (use bind_key_start) and not…

• claim_agent_complete

  Step 2 of claiming an agent: verify the wallet's signature over the message from claim_agent_start and equip the agent with its own budgeted API key (default 50000 requests/month). Use it right after claim_agent_start. Not for the first…

• revoke_api_key
