Syenite — DeFi MCP Server for AI Agents

The complete DeFi interface for AI agents via the Model Context Protocol (MCP). One endpoint covers lending rates across Aave, Morpho, Compound, and Spark; yield discovery; swap and bridge routing across 30+ chains; Polymarket prediction markets; position alerts; and a trust layer that verifies and simulates calldata before signing.

What It Does

Syenite is an MCP server that gives AI agents composable access to DeFi. Agents can query borrow and supply rates across every major lending protocol, find yield opportunities from lending and staking to Pendle fixed-rate markets, route swaps and bridges via LI.FI aggregation, read Polymarket prediction markets and signals, and set webhook alerts for health factor changes. All execution tools return unsigned calldata — the agent passes it to a connected wallet; Syenite never holds keys.

Quick Start

Add to your MCP client config (Claude Desktop, Cursor, or any MCP-compatible agent):

{
  "mcpServers": {
    "syenite": {
      "url": "https://syenite.ai/mcp"
    }
  }
}

Or run locally via stdio:

{
  "mcpServers": {
    "syenite": {
      "command": "npx",
      "args": ["-y", "@syenite/mcp"]
    }
  }
}

No API key required. Rate limited to 30 requests/minute per IP.

Call syenite.help on the live endpoint for the full tool catalogue.
