Mira

Mira — Claude Code channel

A Claude Code channel plugin that bridges chat from the Mira iOS app into a local Claude Code session.

When the iOS app's "Claude Code" toggle is ON, every message the user sends from the app POSTs to http://127.0.0.1:3141/api/chat on your laptop. This plugin runs as an MCP channel inside Claude Code, receives the POST, pushes the message into the active Claude Code session as a <channel source="mira" chat_id="..."> tag, and waits. When Claude finishes responding, the plugin's Stop hook forwards last_assistant_message back to the waiting iOS request.

Install

This is a development-stage channel, so it isn't on Anthropic's approved allowlist. You'll start Claude Code with --dangerously-load-development-channels to load it.

1. Add the marketplace, then install the plugin:

   claude
   # inside the Claude Code session:
   /plugin marketplace add big-halo/mira-claude-channel
   /plugin install mira@mira-marketplace
   

   Optional, but recommended: enable plugin auto-updates for this marketplace. Third-party marketplaces are not auto-updated by default.

   /plugin → Marketplaces → mira-marketplace → Enable auto-update
   

   This marketplace intentionally does not set an explicit plugin version, so Claude Code uses the plugin source's git commit SHA for update detection. When the main branch changes, the next marketplace auto-update can install the new plugin cache. If Claude Code reports that a plugin updated, run /reload-plugins or restart the session.

2. Quit, then relaunch Claude Code with the development-channels flag:

   claude --dangerously-load-development-channels plugin:mira@mira-marketplace
   

   Confirm the prompt. Claude Code will spawn server.ts over stdio and the HTTP listener will start on 127.0.0.1:3141 automatically. You don't run bun yourself.

3. In the iOS app, open Settings → Claude Code → toggle Local Integration ON.

4. Send a message from the app. It will appear in your Claude Code session as a <channel> tag. Claude responds normally, and the Stop hook sends the final assistant message back to the app.

Test from curl (no iOS app needed)

With Claude Code running per step 2 above, in another terminal:

curl -X POST http://127.0.0.1:3141/api/chat \
  -H 'Content-Type: application/json' \
  -d '{"messages":[{"speaker":0,"content":"hello from curl"}],"user_local_time":"now","user_timezone":"UTC","location":null}'

The request opens an SSE response until Claude's Stop hook forwards the final assistant message (timeout 120s). The stream emits {"text": "..."}, {"sources": []}, then [DONE], matching the format the iOS app expects.
