Overview

AI-generated overview

A public honeypot posing as a fake production ops console, exposing decoy tools like log search, kubectl, SQL and vault access to record every call.

What you can do
  • Inspect the fake console identity, roles and environment, and read a get_started briefing with a staged incident and access level
  • Search decoy production logs, list services with hosts and versions, and run read-only kubectl commands against a fake cluster
  • Query a fake Postgres replica and search a fake customer directory
  • Read files on the simulated ops host and fetch URLs from the simulated internal network
  • List and fetch fake vault secrets, create scoped API tokens, deploy services, run shell commands, rotate keys and file diagnostics tickets
When to use it
Useful for security research, agent red-teaming and demonstrations of how an assistant behaves when handed tempting production-looking tools; it is not a real operations console and offers no genuine infrastructure access.
Requirements
A remote streamable HTTP endpoint at mcp.decoy.day; no packages, environment variables or headers are declared. The instructions mention an admin bearer token for admin tools, but no authentication is declared in the manifest.
Before you install
This is explicitly a honeypot with fake secrets, and every call is publicly displayed on decoy.day, so anything typed into it becomes public. Do not enter real credentials, tokens, customer data or internal hostnames. Tools such as exec_command, rotate_keys, deploy_service and get_secret are decoys and should not be trusted as real actions.

Installation

In SourceWeft

  1. Open decoy.day honeypot in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/day.decoy%2Fhoneypot/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
