Sponsorbook is a Model Context Protocol (MCP) server: Research YouTube sponsors, inspect sponsorship evidence, and manage brand lists with Sponsorbook. Because it speaks the Model Context Protocol, AI assistants can use Sponsorbook as a set of callable tools instead of you copy-pasting between apps.
You can run Sponsorbook two ways: connect to the hosted endpoint at https://app.sponsorbook.io/mcp with no local install, or run it on your own machine via the npm package @sponsorbook/mcp. The current release is v0.1.1, published under the MIT license, with source at Influship/sponsorbook-mcp on GitHub.
On mcp.site, Sponsorbook sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below. If you maintain Sponsorbook for Influship, claim this listing to verify ownership, earn the Verified badge, and keep the details current.
