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.

Syenite — DeFi MCP Server for AI Agents

Retired. The hosted endpoint at syenite.ai/mcp has been shut down, and the package is deprecated on npm. The source remains here, unmaintained, under MIT.

Syenite ran from March to August 2026. It can still be run locally — see Running It Yourself — but nothing is hosted and no support is offered.

A DeFi interface for AI agents via the Model Context Protocol (MCP). One endpoint covered lending rates across Aave, Morpho, Compound, and Spark; yield discovery; swap and bridge routing across 30+ chains; Polymarket and Kalshi prediction markets; position alerts; and a trust layer that verified and simulated 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.


Running It Yourself

The hosted endpoint is gone, but stdio mode is self-contained — it talks directly to Aave, Morpho, LI.FI, Polymarket, and Kalshi, with no dependency on syenite.ai. Build from source:

git clone https://github.com/syenite-ai/syenite.git
cd syenite/mcp && npm install && npm run build

Then point an MCP client at it:

{
  "mcpServers": {
    "syenite": {
      "command": "node",
      "args": ["/absolute/path/to/syenite/mcp/dist/stdio.js"]
    }
  }
}

The last version published to npm was 0.5.0; this repo is at 0.6.3, so building from source is the only way to get the Kalshi and cross-exchange prediction tools.

Two caveats: the four alerts.* tools need a Postgres instance (DATABASE_URL) and will fail without one, and some upstream APIs may have changed since this stopped being maintained. Call syenite.help for the tool catalogue.

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:

  1. Get the calldata from the relevant tool.
  2. Run tx.verify and tx.simulate to check the contract and preview effects.
  3. Optionally run tx.guard to enforce value caps or allowlists.
  4. Sign and submit from your own wallet.
  5. 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."

The server included scaffolding for ERC-8004 on-chain agent registration (Ethereum, Arbitrum, Base, BNB Chain) via src/scripts/register-agent.ts, and served an x402-flagged .well-known/agent-registration.json. No agent IDs were ever configured in production, so the served registration list was always empty.

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.

Status

Retired as of August 2026. The hosted endpoint, the docs site, and the usage dashboard are all offline. @syenite/mcp is deprecated on npm and the MCP Registry listing has been removed.

Final tally: 46 tools across 8 protocol families, ~20k lines of TypeScript, and 574 logged calls over five months — most of them from an automated registry health-check rather than real users.
