Vahtian

Overview

Vahtian is a Model Context Protocol server that freezes a corpus, detects drift, and maintains a hash-chained audit ledger for research integrity. It operates entirely locally using only the Python standard library, enabling any MCP-compatible AI assistant to call its tools directly during conversations or agent runs.

The server runs locally via the Python package vahtian using uvx vahtian, communicating over stdio without requiring any credentials or external authentication. It ships as v0.2.0 under the Apache-2.0 license with source code available at heidihelena/vahtian on GitHub.

Vahtian is categorized under Finance on mcp.site and integrates with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim the listing to verify ownership and keep the information current.
