Sequesign

Overview

Sequesign is a Model Context Protocol server that generates cryptographically verifiable receipts of an agent's delegated work, verified offline. Any MCP-compatible AI assistant can call Sequesign's tools directly, letting the model decide when to use them during conversations or agent runs.

The server runs locally via the npm package @sequesign/mcp, which communicates over stdio on your machine. It requires an API Key for authentication. The current release is v0.4.1, published under the Apache-2.0 license with source code available at Sequesign/mcp on GitHub.

Sequesign is categorized as Finance on mcp.site and integrates with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Sequesign, claim this listing to verify ownership and keep details current.
