VERIFIEDPublisher claims: "MCP Server for LeetCode API (supports leetcode.com and leetcode.cn)" Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Server started and answered tools/list.- Tested
- MCP initialize and tools/list · every tool description, for hidden instructions · every file read, file written and host contacted by what ran
- Not tested
- what the tools do when called with real credentials
Before you give it your token
- It will ask for
- no credential variables read in the code
- Where it talks to
- no vendor host named in the codeAlso leetcode.cn, leetcode.com — not the publisher's domain; check what for before connecting.
- What the honeypot saw
- no credential files read · no network
- What we could not test
- what the tools do when called with real credentials
Connect it under the guard; read the third-party hosts first. The code names leetcode.cn, leetcode.com as well as its own vendor. The guard pins the network to the hosts the honeypot saw.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.
