Today is the operative word: we check FeeFighter every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

annual

annual_cost

Project the cumulative cost of a fee list over 1-30 years by straight multiplication of each recurring fee's annualized amount, with one-time fees counted once (no compounding or inflation), with a per-fee breakdown. Use for 'what will these cost me over N years'. It does not flag fees: use audit_fees to find problem charges, benchmark_fees for typical ranges.

audit

audit_fees

Audit a list of fees: annualize each one (monthly x12), total the yearly cost and monthly average, and flag charges above the typical US range for their category, duplicate names and one-time fees of $30+ worth disputing. Use when the user lists fees to review. For a multi-year projection use annual_cost; for typical ranges alone use benchmark_fees.

benchmark

benchmark_fees

Look up typical US consumer fee ranges (min/max per charge, USD) for one category such as bank_overdraft, or the full 14-category table when category is omitted. Use to answer 'is this fee normal?' questions. To check a user's own list of fees against these ranges, use audit_fees.

dispute

dispute_letter

Draft (text only; nothing is sent) a firm, polite letter asking a company to reverse or refund one specific fee, with grounds, a 14-day written-response request, an escalation path and sending tips. Use once the user has picked a fee to contest. To find which fees are worth disputing first, use audit_fees.

FeeFighter — questions

Answers built from our own checks of this server.

What can FeeFighter do?

It exposes 4 tools, read directly from the server on our last check. Among them: annual_cost, audit_fees, benchmark_fees, dispute_letter. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is FeeFighter working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 120 ms. The bar chart above shows every period we have measured.

How do I connect FeeFighter?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does FeeFighter need an API key?

No. FeeFighter completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is FeeFighter?

It answers our handshake in 120 ms on average, which is faster than 78% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is FeeFighter open source?

Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
