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
DEVFLOW_SESSION_TOKENConfiguration, not credentials: CLAUDE_PLUGIN_ROOT, CLAUDE_PROJECT_DIR, DEVFLOW_ACTOR_ID, DEVFLOW_ACTOR_KIND, DEVFLOW_ACTOR_ROLE, DEVFLOW_DELIVERY_AUTOMATION, DEVFLOW_DELIVERY_EXECUTION, DEVFLOW_EVALUATION_BUNDLE_ID, DEVFLOW_EXECUTION_ID, DEVFLOW_MCP_TOOLS, DEVFLOW_MCP_VERSION, DEVFLOW_PROJECT_ROOT, DEVFLOW_RELEASE_RUN_ID, DEVFLOW_SESSION_ID
Where it talks to
no vendor host named in the code
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 with a scoped credential, under the guard. It asks for DEVFLOW_SESSION_TOKEN and talks to its vendor. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind.

$vet-skills run --net declared -- npx -y @devflow-tools/mcp-server

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

Is [email protected] safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-11 and scored it 87/100 (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.
