What Fakechat is
Fakechat is a plugin published in the anthropics/claude-plugins-official repository on GitHub, which has about 37.1k stars. The repository describes itself as: “Official, Anthropic-managed directory of high quality Claude Code Plugins.”
A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.
Installing Fakechat adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.
How to install Fakechat
Claude Code
- Add the repository as a plugin marketplace: claude plugin marketplace add anthropics/claude-plugins-official
- Install the plugin: claude plugin install fakechat@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
- Restart the session if the new skills or commands don't appear straight away.
Claude Cowork
- Open Customize → Plugins and choose Add marketplace.
- Enter anthropics/claude-plugins-official (the owner/repo shorthand works for GitHub).
- Find Fakechat in the list, click Install, then connect any connectors it needs from its Connectors tab.

Inside the source file
An excerpt from external_plugins/fakechat/.claude-plugin/plugin.json, shared under the repository's Apache-2.0 license. Read the full file on GitHub.
Simple UI for testing the channel contract without an external service. Open a browser, type, messages go to your Claude Code session, replies come back.
Setup
These are Claude Code commands — run claude to start a session first.
Install the plugin:
/plugin install fakechat@claude-plugins-officialRelaunch with the channel flag — the server won't connect without this. Exit your session and start a new one:
claude --channels plugin:fakechat@claude-plugins-officialThe server prints the URL to stderr on startup:
fakechat: http://localhost:8787Open it. Type. The assistant replies in-thread.
Set FAKECHAT_PORT to change the port.
Tools
Inbound images/files save to ~/.claude/channels/fakechat/inbox/ and the path is included in the notification. Outbound files are copied to outbox/ and served over HTTP.
Not a real channel
There's no history, no search, no access.json, no skill. Single browser tab, fresh on every reload. This is a dev tool, not a messaging bridge.
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
