Overview

AI-generated overview

Lets an assistant analyze US stock and ETF portfolios, including risk, correlation, and ETF overlap, for over 4,700 securities.

What you can do
This local MCP server provides portfolio analysis tools covering more than 4,700 US stocks and ETFs. Based on its description, it can assess portfolio risk, compute correlations between holdings, and identify overlap between ETFs. It is distributed as the npm package pairbook-mcp and runs over stdio on the user's machine.
When to use it
Useful when an assistant needs to evaluate a US stock or ETF portfolio, check how holdings correlate, or see whether multiple ETFs duplicate the same exposure. It is aimed at portfolio review and diversification questions rather than trading or market data feeds.
Requirements
Runs as a local process, so a Node.js runtime is needed to run the npm package pairbook-mcp over stdio. The description states it is free and requires no API key, and the manifest declares no environment variables, headers, or authentication. Network access is likely needed to fetch market data, though this is not stated explicitly.
Before you install
The description says it is free and needs no key, and the manifest declares no credentials. It is desktop-only and not available as a web executable. The description does not state whether it only reads data or also writes anything, and it does not identify which third-party data source is used, so treat any data it returns as informational rather than investment advice.

Installation

In SourceWeft

  1. Open Pairbook Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
