Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`CK_COOKIES` Optional, secret	Optional. The full Cookie header from a signed-in creditkarma.com request. Leave unset to use the browser fallback — install ContextMint Bridge (https://github.com/nullnet-app/contextmint-bridge/releases), sign into creditkarma.com, and the MCP reads cookies automatically. Otherwise copy the header…
`CK_DISABLE_FETCHPROXY` Optional	Set to 1 to skip the ContextMint Bridge browser-extension fallback (missing creds become a hard error — useful in headless CI).
`CK_DEBUG` Optional	Set to 1 to trace auth to stderr: credential source, cookie names, token issue/expiry times, and the token-refresh exchange. Never logs token or cookie values.
`CK_DB_PATH` Optional	Path to SQLite database file (default ~/.creditkarma-mcp/transactions.db).
`CK_SESSION_PATH` Optional	Saved-session file that ck_set_session and token refreshes write (default ~/.creditkarma-mcp/session).
`CK_CREDIT_BUREAU` Optional	Credit report used for card and loan balances: transunion or equifax (default transunion).
`CK_SYNC_MAX_PAGES` Optional	Pages one ck_sync_transactions call may fetch before pausing. Unset (or unparseable) = unbounded, which is what a local stdio server wants. Set it on a hosted deployment, where the call has to answer inside the client's request timeout.
`FETCHPROXY_WS_PORT` Optional	Localhost port of the fetchproxy concentrator the ContextMint Bridge extension connects to (default 37149). Every MCP on one machine shares it, so move it for all of them or not at all.
`FETCHPROXY_WS_HOST` Optional	Bind interface for the fetchproxy concentrator, a literal IP only (default 127.0.0.1). Keep on loopback; it exists for hosted deployments that run each MCP in its own network namespace.
`FETCHPROXY_IDENTITY_DIR` Optional	Absolute path where the fetchproxy long-term identity keypair is stored (default ~/.fetchproxy/identity/).
