Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account vj88-coder for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Local MCP server that gives an assistant portfolio risk analysis, correlation and ETF overlap data for 4,700+ US stocks and ETFs.

What you can do: Analyze portfolio risk for US stocks and ETFs
Compute correlations between holdings
Check ETF overlap across funds
Look up coverage spanning 4,700+ US stocks and ETFs
When to use it: Useful when you want an assistant to review a US stock or ETF portfolio, compare holdings for correlation, or check how much two ETFs overlap. It is a narrow, free data tool rather than a general market data feed.
Requirements: Runs as a local stdio process, installed from the npm package pairbook-mcp, so Node.js and npm are needed. No API key or environment variables are declared, and the provider describes it as free.

Before you install

The manifest lists no tools, so the exact operations and their inputs are not documented here; confirm them before relying on results. Analysis output is informational and should not be treated as investment advice. Desktop only; no web execution.
