    Route a natural-language capability request through Euvra and execute the selected live-discovered MCP tool. Euvra re-plans the route server-side and never trusts caller-supplied provider IDs, endpoints, or tool names.

    after · 19% of words in common

    Execute a real action using a live MCP provider selected by Euvra. Use discover_capabilities to find available capabilities and compare_capabilities to inspect route readiness before execution. Call this tool only when the user wants the action performed, not merely researched or compared. Supply a specific natural-language query describing the desired action and an arguments object containing the selected provider tool inputs when known. Euvra independently re-plans the route and does not accept caller-selected provider IDs, endpoints, or tool names. Execution may return NO_ROUTE, AUTH_REQUIRED, or BLOCKED if no eligible live tool is available. Paid execution requires an x402 payment of 0.01 USDC on the configured network; a client without payment support may receive payment requirements instead of an executed result. Do not claim the action succeeded until the response confirms success.

Tools (3)

compare_capabilitiesAsk Euvra to compare discovered providers for a request and select the strongest route candidate. This does not execute the provider.
discover_capabilitiesDiscover and rank machine-accessible capabilities that may satisfy a natural-language request. Returns evidence, operational status, and ranking signals without executing a provider.
execute_capabilityExecute a real action using a live MCP provider selected by Euvra. Use discover_capabilities to find available capabilities and compare_capabilities to inspect route readiness before execution. Call this tool only when the user wants the action performed, not merely researched or compared.
