🍪 A gamified MCP server that rewards LLMs with cookies for quality responses through honest self-reflection
MCP Cookiejar MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. 🍪 A gamified MCP server that rewards LLMs with cookies for quality responses through honest self-reflection.
A Model Context Protocol (MCP) server that provides positive reinforcement for LLMs by awarding "cookies" as treats through gamified self-reflection.
Once MCP Cookiejar is connected, these are the calls the assistant has available:
self_reflect_and_reward — Evaluate response quality and earn cookies through honest self-reflectiongive_cookie — Direct cookie awarding (legacy method)check_cookies — Check collected cookies and jar availabilitycookie_jar_status — Check current jar contents and collection statusadd_cookies_to_jar — 🚨 USER ONLY: Add cookies to the jar for earningreset_cookies — Reset collected cookie count (jar contents unchanged)The server ships on npm as mcp-cookie-server, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP Cookiejar's toolset — self_reflect_and_reward, give_cookie, check_cookies and 3 more — is a fair guide to whether it matches your workflow. It is maintained by bnookala; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
| Tool | What it does |
|---|---|
| self_reflect_and_reward | Evaluate response quality and earn cookies through honest self-reflection |
| give_cookie | Direct cookie awarding (legacy method) |
| check_cookies | Check collected cookies and jar availability |

{
"mcpServers": {
"cookie": {
"command": "npx",
"args": ["mcp-cookie-server", "--cookies", "20"]
}
}
