Summary
If your agent needs to interact with DeFi protocols without holding keys, this is the integration. It surfaces lending rates across Aave, Morpho, Compound, and Spark, yield opportunities from Pendle to liquid staking, swap and bridge routing via LI.FI across 30+ chains, and Polymarket prediction markets. Every execution tool returns unsigned calldata that you verify with tx.simulate and tx.verify before signing with your own wallet. The position monitoring hooks let you watch health factors and set webhook alerts for liquidation risk. It's built for agents that compose primitives: query rates, screen for carry trades, route a swap, all in one workflow without managing protocol-specific SDKs.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

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.
Live at syenite.ai · Docs at syenite.ai/docs
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.

Supported Protocols

Supported Chains
Swap and bridge (via LI.FI): Ethereum, Arbitrum, Base, Optimism, Polygon, BNB Chain, Avalanche, zkSync, Linea, Scroll, Gnosis, Fantom, and 20+ more.
Lending rates, execution, and position monitoring: Ethereum, Arbitrum, Base (per protocol availability).
Wallet, gas, and trust simulation: Ethereum, Arbitrum, Base, BNB Chain.
How Execution Works
All execution tools (lending.supply, lending.borrow, lending.withdraw, lending.repay, swap.quote) return unsigned transactionRequest objects — calldata ready to sign. The recommended flow:
- Get the calldata from the relevant tool.
- Run
tx.verifyandtx.simulateto check the contract and preview effects. - Optionally run
tx.guardto enforce value caps or allowlists. - Sign and submit from your own wallet.
- Confirm with
tx.receipt.
Syenite never holds private keys or custody of funds.
Agent Integration
Syenite is designed for agent-native DeFi workflows. Every tool is an atomic primitive: agents compose them to achieve outcomes like "find the best lending rate for wBTC, supply collateral, and set a health factor alert."
Syenite is a registered on-chain agent via ERC-8004 on Ethereum, Arbitrum, Base, and BNB Chain, and supports x402 machine-to-machine payments.
The server.json manifest includes a systemPrompt field that MCP clients can inject to orient the agent on Syenite's capabilities automatically.
Call syenite.help for the full capability overview including all tool parameters.
