Thunderduck
Exchange a few credentials in the console and Thunderduck makes S3, GCS, Azure, PostgreSQL, MySQL, MsSQL and BigQuery queryable in one place for your analysts, your AI agents via MCP and applications via Alchemy, JDBC and Rest Api. A self-learning engine sizes every query and checks its cost before it runs, so agents can explore freely without blowing your budget or touching production.

Get your MCP into directories
A working endpoint is step one. Directory coverage is the coordinated launch across ChatGPT, Claude, Cursor, the MCP Registry, and community indexes.

Use the remote MCP URL on this page in your MCP client (Claude, Cursor, VS Code, and more). Copy the endpoint if your client needs a manual entry, then complete provider sign-in when your client connects — tools appear after authentication.
This endpoint requires provider sign-in, so MCPBundles could not list tools anonymously during the last probe. After you connect and authenticate in your MCP client, your session should receive the live tool list from the provider.
Thunderduck may require signing in to the provider before tools can run. Connect through MCPBundles or your MCP client and complete any provider login when prompted.
Operate Thunderduck? Verify ownership to take over this directory entry.
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles is an independent platform built on the open Model Context Protocol standard. Not affiliated with Anthropic PBC or Claude.
