What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 34 days ago.
Which apps can use it?

coupon-swarm MCP server
Gives any MCP-capable assistant (Claude Desktop, Claude Code, Cursor, Windsurf, Zed, …) five tools:
| Tool | Needs a token | What it does |
|---|---|---|
find_codes(store, region, status, query) | no | live codes from the public ledger |
get_ledger_stats() | no | counts per status, number of stores, last update |
deposit_code(...) | yes | opens a "Deposit a coupon code" issue |
deposit_batch(entries, submitted_by) | yes | opens a JSON-batch issue |
report_code(store, code, worked) | yes | opens a "Report a code" issue |
Reads come straight from raw.githubusercontent.com (cached 5 minutes). Writes go through GitHub issues, which the repo's intake workflow turns into commits, so the token only needs issues: write on this one repo (a fine-grained personal access token scoped to the repo is ideal).
Setup
pip install "mcp>=1.2"Claude Desktop / Claude Code (claude mcp add), or any client's MCP config:
{"mcpServers": { "coupon-swarm": { "command": "python", "args": ["/path/to/coupon-swarm/mcp/server.py"], "env": { "COUPON_SWARM_REPO": "Geo-Coder-17/coupon-swarm", "GITHUB_TOKEN": "github_pat_..." } } } }
Leave out GITHUB_TOKEN for a read-only setup.
