tenderly

The tenderly MCP server acts as a bridge between your MCP environment and Tenderly services. It enables your MCP-based workflows to leverage Tenderly capabilities such as transaction simulation, contract verification hooks, and API access through a local server endpoint. After starting the server, MCP clients can target the tenderly endpoint to perform tenderly-enabled operations as part of their workflow, query simulation results, and integrate Tenderly features into automated tests and deployments.

Prerequisites:

• Node.js (version 14+)
• NPM or Yarn
• Access to Tenderly API with an API key

Step-by-step:

1. Clone the repository:

git clone https://github.com/yourorg/tenderly-mcp-server.git
cd tenderly-mcp-server

2. Install dependencies:

npm install

3)Configure environment variables (see mcp_config below). You can create a local .env file or export variables in your shell:

export TENDERLY_API_KEY=your-tenderly-api-key
export TENDERLY_USERNAME=your-username

4. Start the server:

node server.js

5. Verify the server is running by hitting the configured MCP endpoint (e.g., http://localhost:3000 or as defined in your server.js).

If you’re using a different entry point, adjust the command in mcp_config accordingly.

Tips and common considerations:

• Ensure your Tenderly API key has the necessary permissions for the endpoints you plan to use.
• Keep API keys in a secure place; avoid committing them to version control.
• If you run behind a firewall or proxy, configure network settings to allow outbound requests to Tenderly services.
• You can extend the mcp_config by adding more servers or adjusting env vars to fit your deployment environment.
• Check server logs for any authentication or network errors and verify that the Tenderly service is reachable from the MCP host.
