VerifiedSTDIODesktop only

Overview

PointMaxx's local MCP server; no sign-in required; STDIO; 3 tools.

No AI overview yet: these facts come from the registry entry and the server itself.

Installation

In SourceWeft

  1. Open PointMaxx 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.

Other MCP clients

Follow the launch instructions in the repository.

README

pointmaxx-mcp

Ask your AI assistant which credit card to use, and which cards would earn you the most, with the same math as pointmaxx.app. Compares 53 U.S. credit cards after annual fees, spending caps and the credits you'd actually use.

Set it up

Claude Desktop: open Settings, then Developer, then Edit Config, add this, and restart Claude:

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

Any other MCP app: run npx -y pointmaxx-mcp as a stdio server. Needs Node 18 or later.

What you can ask

ToolAsk your assistant something like
best_card"I have Amex Gold and Citi Double Cash. Which should I use on DoorDash?"
compare_cards"I spend about $500 a month on groceries, $300 on dining and $1,500 on everything else. Which two cards would earn the most? I have a Double Cash."
card_terms"What's the annual fee on the Sapphire Reserve, and what are its credits?"

Answers include each card's percent back, why it wins, any spending cap, the net value a year after fees, and how much more that is than the cards you already have.

Privacy

It runs on your own computer and makes no network requests. It only needs card names and rough monthly spending by category: never statements, card numbers or a login. Nothing is saved.

Good to know

  • Estimates from each card's published terms, checked against issuer pages. Not financial advice; check the issuer before you apply.
  • Points are valued at a fixed cents-per-point for each card. Sign-up bonuses are left out.
  • Card terms are built into each release. Run with npx -y pointmaxx-mcp to always get the latest.

For a full backtest on a year of your own statements, read in your browser and never uploaded, try pointmaxx.app.

Source

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
