Trigger Web3 SQL Queries in Claude Desktop

This MCP Server uses `execute_query` to spin up blockchain database runs directly from your chat window. You give your agent a query ID and parameters, and it fires off the database execution to start gathering live on-chain metrics. This tool returns an execution ID immediately. Your agent then monitors the run progress and fetches the final dataset once the query completes.

Monitor and Control Live Executions

This MCP Server uses `get_execution_status` to monitor active database runs from your desktop. Your agent checks if the database is still processing your request so you know exactly when the data is ready. If a query takes too long or uses too many API credits, you can stop it immediately. Your agent invokes `cancel_execution` to terminate the active run and prevent wasted API budget.

Pull Raw Blockchain Data Rows

This MCP Server uses `get_execution_results` to pull completed data rows directly into your chat. When the status check returns complete, the agent grabs the raw dataset. You get clean rows of on-chain metrics directly inside your chat window. From there, Claude Desktop can format the data, write scripts to parse it, or build tables.

Common questions about Dune Analytics (Web3 SQL Analytics API) MCP in Claude Desktop

This MCP server configures directly in your local `claude_desktop_config.json` file. You add the server configuration under the `mcpServers` block, provide your API key as an environment variable, and restart the application.

Yes, you can execute any query saved on your account by passing its query ID to the server. Your agent uses `execute_query` with your specific parameters to trigger the run.

Your agent can check the execution state and cancel it if it hangs. It calls `get_execution_status` to verify the state and then triggers `cancel_execution` to stop the run.

You need a valid Dune API key with sufficient execution credits. The MCP server uses your credentials to authenticate all calls directly with Dune's API.

Your API keys and SQL query parameters stay entirely on your local machine. The server runs inside a local sandbox and communicates directly with Dune over HTTPS, meaning no third-party server ever intercepts your database execution IDs or result rows.
