MisterMorph ACP Claude Adapter

This package exposes an ACP stdio adapter for Claude Code.

Current shape:

• transport: stdio
• ACP methods:
  • initialize
  • authenticate (no-op)
  • session/new
  • session/set_config_option
  • session/prompt
  • session/cancel
• backend: claude -p --output-format stream-json

Current limits:

• no session persistence
• no MCP passthrough
• no interactive approval flow
• the adapter does not bridge Claude tool calls back into ACP file or terminal callbacks

Run it directly:

node ./packages/claude/src/index.mjs

Or from the repository root:

npm run run:claude

Example ACP profile:

acp:
  agents:
    - name: "claude"
      command: "node"
      args: ["./packages/claude/src/index.mjs"]
      env: {}
      cwd: "."
      read_roots: ["."]
      write_roots: ["."]
      session_options:
        permission_mode: "dontAsk"
        allowed_tools: ["Read", "Edit", "Write", "Bash", "Glob", "Grep"]

Notes:

• bare: true is optional, but it is not safe as a default when you rely on Claude.ai login.
• Claude Code bare mode skips OAuth and keychain reads, so Claude.ai login usually requires bare: false.

Optional environment variables:

• MISTERMORPH_CLAUDE_COMMAND
  • override backend executable, default claude
• MISTERMORPH_CLAUDE_ARGS
  • extra backend args, whitespace-split, inserted before print-mode flags

Test:

npm run test:claude
