xeer-mcp@0.2.40
VERIFIEDPublisher claims: "Model Context Protocol server for Xeer project context, diagnostics, scaffold, check, test, dev, build, and preview deployment." 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
- xeer.run (its own)
- What the honeypot saw
- no credential files read · no network
- What we could not test
- what the tools do when called with real credentials
Reasonable to connect. No credential asked for, no third-party host named, Server started and answered tools/list.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-14 and scored it 89/100 (Verified). It did what it claims and nothing else we could detect: no undeclared network egress, no credential reads, no persistent instruction writes. Summary: no network, touches nothing outside the project, writes no memory.

Tokens estimated at four characters each. The tool list is re-read by the agent on every turn, so it is the number to compare between servers that do the same job: ranked across the index.
