tellermcp-mcp

What This Skill Does

The tellermcp-mcp skill provides an interface to the Teller Finance protocol, allowing OpenClaw agents to interact directly with delta-neutral arbitrage opportunities, lending pools, and on-chain transaction builders. By implementing the Model Context Protocol (MCP), this skill bridges the gap between natural language agent requests and the technical REST endpoints of Teller’s infrastructure. It acts as a standardized translation layer, converting complex DeFi data—such as borrow rates, collateral requirements, and repayment schedules—into actionable tool outputs for the agent.

Installation

To install, ensure you are within the OpenClaw environment and the scripts directory for the skill exists.

1. Navigate to the project root: cd scripts/tellermcp-server
2. Install dependencies: npm install
3. Build the server: npm run build
4. Update your mcporter or OpenClaw configuration file to include the tellermcp server. Ensure the cwd field points to the absolute path of the tellermcp-server directory.
5. Restart your agent or mcporter process to register the new tools.

Use Cases

• DeFi Yield Optimization: Agents can query delta-neutral opportunities to identify arbitrage strategies with minimal market exposure.
• Lending Automation: Automatically fetch borrow pools and terms to facilitate faster decision-making for loans.
• Transaction Construction: Generate raw transaction payloads for borrowing or repayment, which can then be signed and broadcasted by a connected wallet.
• Portfolio Management: Track existing loans and health ratios by querying wallet-specific loan data via the MCP tools.

Example Prompts

1. "Find the best delta-neutral opportunities for ETH and tell me the borrow APY for each pool."
2. "Build a transaction to borrow 500 USDC against my current collateral and list the expected gas fees."
3. "What is the current repayment amount for my open loan on the Teller protocol?"

Tips & Limitations

Always verify transaction payloads before signing. The tool provides raw JSON responses; ensure your agent environment has sufficient parsing logic to handle the structured data. The skill relies on the TELLER_API_BASE_URL; if you experience connectivity issues, check your network environment and verify the API status at the provided endpoint. The server currently defaults to stdio transport, so ensure the parent agent process has standard I/O communication enabled with the server.
