Zekher Beta

Zekher's MCP Server

Zekher provides a Model Context Protocol (MCP) server that enables access to Yad Vashem's Holocaust Lexicon content through any MCP-compatible AI client, including Anthropic's Claude, OpenAI's ChatGPT, and custom applications. The server provides structured access to historical information with proper citations and usage guidelines. It now supports MCP Apps so compatible hosts can render an interactive Zekher Lexicon Explorer UI inline with tool calls.

Available Capabilities

Once connected, the MCP server provides access to these capabilities. For optimal setup and citation generation, it's important to use both the prompt and tool together:

Tools

yad_vashem_holocaust_lexicon

Search Yad Vashem's Holocaust Lexicon and return cited historical sources. In MCP Apps-capable hosts, this tool renders the interactive lexicon explorer UI.

Parameters: Search terms to query the Holocaust Lexicon (maximum 6 terms), plus confirmInstructionsRead: true

yad_vashem_lexicon_entry_detail

App-only tool used by the MCP App UI to fetch full entry details for a selected lexicon result.
