Package Exports

pageindex-mcp
pageindex-mcp/build/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (pageindex-mcp) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

What is PageIndex?

PageIndex is a vectorless reasoning-based RAG system which uses multi-step reasoning and tree search to retrieve information like a human expert would. It has the following properties:

Higher Accuracy: Relevance beyond similarity
Better Transparency: Clear reasoning trajectory with traceable search paths
Like A Human: Retrieve information like a human expert navigates documents
No Vector DB: No extra infrastructure overhead
No Chunking: Preserve full document context and structure
No Top-K: Retrieve all relevant passages automatically

PageIndex MCP Setup

See PageIndex MCP for full video guidances.

1. For Claude Desktop (Recommended)

One-Click Installation with Desktop Extension (MCPB):

Download the latest .mcpb file from Releases
Double-click the .mcpb file to install automatically in Claude Desktop
The OAuth authentication will be handled automatically when you first use the extension

Note: Claude Desktop Extensions now use the .mcpb (MCP Bundle) file extension. Existing .dxt extensions will continue to work, but we recommend using .mcpb for new installations.

This is the easiest way to get started with PageIndex's reasoning-based RAG capabilities.

2. For Other MCP-Compatible Clients

Option 1: Local MCP Server (with local PDF upload)

Requirements: Node.js ≥18.0.0

Add to your MCP configuration:

{
  "mcpServers": {
    "pageindex": {
      "command": "npx",
      "args": ["-y", "pageindex-mcp"]
    }
  }
}

Note: This local server provides full PDF upload capabilities and handles all authentication automatically.

Option 2: Direct Connection to PageIndex

Connect directly to the PageIndex OAuth-enabled MCP server:

{
  "mcpServers": {
    "pageindex": {
      "type": "http",
      "url": "https://mcp.pageindex.ai/mcp"
    }
  }
}

For clients that don't support HTTP MCP servers:

If your MCP client doesn't support HTTP servers directly, you can use mcp-remote as a bridge:

{
  "mcpServers": {
    "pageindex": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.pageindex.ai/mcp"]
    }
  }
}

Note: Option 1 provides local PDF upload capabilities, while Option 2 only supports PDF processing via URLs (no local file uploads).
