Negbit

Overview

Negbit is a Model Context Protocol server that lets you purchase curated, provenance-verified knowledge bundles using your own x402 wallet. The server operates in read-only mode, giving AI assistants direct access to Negbit's offerings as callable tools rather than requiring manual copy-paste workflows between applications.

It installs locally via npx -y negbit-mcp with no authentication required. The server runs over stdio on your machine, speaking MCP natively. The latest release is v0.1.0 under the CC-BY-SA-4.0 license, with source code available at ag3ntlab-ai/negbit on GitHub.

Negbit appears in the Finance category on mcp.site and works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim your listing to verify ownership and keep information up to date.
