Signet MCP Tools

Overview

Signet MCP Tools is a Model Context Protocol server that exposes cryptographic signing, verification, and content hash capabilities over stdio. It lets AI assistants call Signet's security functions directly as tools, eliminating the need to switch between applications or manually pass data around.

The server runs locally on your machine via the npm package @signet-auth/mcp-tools and requires no authentication to get started. Version v0.4.1 is available now under the Apache-2.0 license, with full source code at Prismer-AI/signet on GitHub where the project has 38 stars.

Signet MCP Tools is listed 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.
