AgentOracle MCP Server

An MCP (Model Context Protocol) server that connects AI assistants like Claude, Cursor, and Windsurf to AgentOracle — a pay-per-query real-time research API for AI agents.

What It Does

This MCP server exposes AgentOracle's research capabilities as tools that any MCP-compatible AI assistant can call:

Tool	Description	Cost
research	Real-time research on any topic — returns structured JSON with summary, key facts, sources, and confidence score	$0.02 USDC
deep-research	Comprehensive deep analysis with expert-level findings, 10-15 detailed facts, and analysis paragraph	$0.10 USDC
check-health	Check if AgentOracle API is online with service status	Free
get-manifest	Get x402 payment manifest with pricing and endpoint details	Free

Payments are handled via the x402 protocol on Base mainnet using USDC.

Quick Start

Install from npm

npm install -g agentoracle-mcp

Or clone and build from source

git clone https://github.com/TKCollective/agentoracle-mcp.git
cd agentoracle-mcp
npm install
npm run build

Usage with Claude Desktop

Add this to your Claude Desktop MCP config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "agentoracle": {
      "command": "npx",
      "args": ["-y", "agentoracle-mcp"]
    }
  }
}

Or if installed globally:

{
  "mcpServers": {
    "agentoracle": {
      "command": "agentoracle-mcp"
    }
  }
}

Usage with Cursor

Add to your Cursor MCP settings:

{
  "mcpServers": {
    "agentoracle": {
      "command": "npx",
      "args": ["-y", "agentoracle-mcp"]
    }
  }
}

Example

Once connected, you can ask your AI assistant things like:

"Use AgentOracle to research the latest DeFi protocol TVL rankings on Base"

The assistant will call the research tool and return structured results:

{
  "query": "Latest DeFi protocol TVL rankings on Base",
  "tier": "standard",
  "result": {
    "summary": "As of March 2026, Base L2 DeFi TVL has reached...",
    "key_facts": [
      "Aerodrome leads Base DeFi with $3.2B TVL",
      "Aave v3 on Base holds $1.8B"
    ],
    "sources": ["https://defillama.com/..."],
    "confidence_score": 0.89
  },
  "confidence": {
    "score": 0.89,
    "level": "high",
    "sources_count": 6,
    "facts_count": 5
  },
  "freshness": "recent",
  "metadata": {
    "model": "sonar",
    "api_version": "1.3.0",
    "response_time_ms": 2100
  }
}

How Payment Works

AgentOracle uses the x402 protocol for payments:

1. The MCP tool sends your query to AgentOracle
2. If no payment header is present, the API returns HTTP 402 with payment requirements
3. Use an x402-compatible client to sign a USDC payment on Base
4. Resubmit the request with the payment header to get full results

The free check-health and get-manifest tools work without any payment.

Resources

The server also provides an embedded API documentation resource at docs://agentoracle/api that MCP clients can access for integration details.
