Sefaria Jewish Library MCP Server: Integrating Jewish Texts into AI Applications

Overview: What is Sefaria Jewish Library MCP Server?

The Sefaria Jewish Library MCP Server provides a standardized interface for Large Language Models (LLMs) and other AI applications to access and reference a vast collection of Jewish texts. This server leverages the Model Context Protocol (MCP) to facilitate seamless integration between AI tools and rich, annotated text data from the Sefaria library.

🔧 Core Features & MCP Capabilities

The Sefaria MCP Server boasts two core capabilities that are crucial for AI integration:

1. Retrieve Jewish Texts by Reference: Users can fetch specific Jewish texts based on their reference, such as "Genesis 1:1" or "משנה ברכות פרק א משנה א". This ability ensures that LLMs and other applications can easily query the server to retrieve relevant content.

2. Retrieve Commentaries on a Given Text: The server supports fetching commentaries on specific textual references, allowing users to gain deeper insights into texts through historical and scholarly perspectives.

AI Workflow Use Case: Summarization of a Biblical Passage

Imagine an LLM that needs to summarize Genesis 1:1 in a way that is both accurate and contextually rich. With the Sefaria MCP Server enabled, the LLM can issue a command like this:

reference: "Genesis 1:1"

Upon receiving the reference, the server retrieves the text along with its associated commentaries from the Sefaria database. The AI application can then process this data to generate a summary that includes both the literal translation and scholarly insights.

AI Workflow Use Case: Contextual Analysis for Historical Research

A researcher working on historical texts might need to analyze a specific passage in context, such as "Shmot Prak B pesuk G" (Exodus 2:3). By sending a request like this:

reference: "שמות פרק ב פסוק ג"

The Sefaria MCP Server will provide the full text and relevant commentaries, facilitating thorough historical research using modern AI tools.

⚙️ MCP Architecture & Protocol Implementation

Model Context Protocol (MCP) Integration

The Sefaria MCP Server is built on the principles of the Model Context Protocol (MCP), which defines a set of rules and actions for AI applications to interact with external data sources. By adhering to MCP, this server ensures compatibility with various AI clients and tools.

Running the Server Locally

To run the server locally, follow these steps:

1. Clone the repository:

   git clone https://github.com/sivan22/mcp-sefaria-server.git
   cd mcp-sefaria-server
   

2. Run the server directly using:

   uv --directory path/to/directory run sefaria_jewish_library
   

3. Alternatively, configure the server to be used by MCP clients through a configuration file:

{
  "mcpServers": {
      "sefaria_jewish_library": {
          "command": "uv",
          "args": [
              "--directory",
              "C:/dev/mcp-sefaria-server",
              "run",
              "sefaria_jewish_library"
          ],
          "env": {
            "PYTHONIOENCODING": "utf-8" 
          }
      }
  }
}
