Discover, compare, route, and execute machine-accessible capabilities for AI agents.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (3)
⚪discover_capabilities(query, limit)
Discover and rank machine-accessible capabilities that may satisfy a natural-language request. Returns evidence, operational status, and ranking signals without executing a provider.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"minLength": 1,
"description": "Natural-language capability request."
},
"limit": {
"type": "integer",
"minimum": 1,
"maximum": 20,
"default": 10,
"description": "Maximum results to return."
}
},
"required": [
"query"
],
"additionalProperties": false
}Output Schema
{
"type": "object"
}🟢compare_capabilities(query, limit)
Ask Euvra to compare discovered providers for a request and select the strongest route candidate. This does not execute the provider.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"minLength": 1,
"description": "Natural-language capability request."
},
"limit": {
"type": "integer",
"minimum": 1,
"maximum": 5,
"default": 5,
"description": "Maximum alternative routes to return."
}
},
"required": [
"query"
],
"additionalProperties": false
}Output Schema
{
"type": "object"
}🟢execute_capability(query, arguments)
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.
