creditkarma-mcp

MCP server for Credit Karma — syncs transactions into a local SQLite database and provides natural-language querying tools.

• npm: npmjs.com/package/creditkarma-mcp
• Source: github.com/chrischall/creditkarma-mcp

Setup

Option A — npx (recommended)

Add to .mcp.json in your project or ~/.claude/mcp.json:

{
  "mcpServers": {
    "creditkarma": {
      "command": "npx",
      "args": ["-y", "creditkarma-mcp"],
      "env": {
        "CK_COOKIES": "CKTRKID=...; CKAT=eyJ...%3BeyJ...; ..."
      }
    }
  }
}

Option B — from source

git clone https://github.com/chrischall/creditkarma-mcp
cd creditkarma-mcp
npm install && npm run build

Then add to .mcp.json:

{
  "mcpServers": {
    "creditkarma": {
      "command": "node",
      "args": ["/path/to/creditkarma-mcp/dist/index.js"],
      "env": {
        "CK_COOKIES": "CKTRKID=...; CKAT=eyJ...%3BeyJ...; ..."
      }
    }
  }
}

Or use a .env file in the project directory with CK_COOKIES=<value>.

Getting CK_COOKIES (optional)

Three onboarding paths, in priority order:

1. fetchproxy extension (easiest — no env vars): Install the fetchproxy 0.3.0 extension, sign into creditkarma.com once, and leave CK_COOKIES unset. The MCP reads HttpOnly CKAT + CKTRKID cookies on the first tool call via chrome.cookies.get, then operates direct-to-API from Node.

2. ck_set_session MCP tool: From within Claude, call ck_set_session with a Cookie header you copied from DevTools (see below). The tool persists it to .env.

3. Manual (DevTools):

1. Log in to creditkarma.com in Chrome
2. DevTools → Network → any creditkarma.com request → Request Headers
3. Right-click the cookie header → Copy value
4. Paste into CK_COOKIES in your Claude config
