get_pet_status reads local pet metadata
record_coding_event records language, line count, test count, file count, and status
list_quests shows progress
clear_pet_history removes local metadata history

Do not send source code to this server. It intentionally accepts metadata only.

Run

npm install
npm run build
node dist/index.js

The state file defaults to ~/.codepet/state.json. Set CODEPET_STATE_FILE to use another local path.

Privacy

No API key is required. The server makes no network requests. It never executes or stores source code.

Quick start

npm install
npm run build
node dist/index.js

The server uses stdio, so it can be connected to Claude Desktop, Cursor, VS Code, MCP Inspector, or another compatible MCP client.

Tools at a glance

get_pet_status: Read CodePet

Try it

After building, connect the server through your MCP client. The repository root also contains smoke-test.mjs for projects covered by the shared harness. A typical tool call starts with get_pet_status.

Premium tools

These tools need a license key:

pet_progress_report
language_breakdown

Buy a key at https://mcp-marketplace.io/server/io-github-mrfentmen-codepet-mcp and set it in your MCP client config:

"env": { "MCP_LICENSE_KEY": "mcp_live_..." }

The key is checked against MCP Marketplace, cached for 24 hours, and keeps working offline once one check has succeeded. Every other tool on this server stays free.
