MisterMorph ACP Codex Adapter

This package exposes an ACP stdio adapter for Codex.

Current shape:

• transport: stdio
• ACP methods:
  • initialize
  • authenticate (no-op)
  • session/new
  • session/set_config_option
  • session/prompt
  • session/cancel
• backend: codex app-server

Current limits:

• no session persistence
• no MCP passthrough
• no interactive approval flow
• default approval_policy is never

Run it directly:

node ./packages/codex/src/index.mjs

Or from the repository root:

npm run run:codex

Example ACP profile:

acp:
  agents:
    - name: "codex"
      command: "node"
      args: ["./packages/codex/src/index.mjs"]
      env: {}
      cwd: "."
      read_roots: ["."]
      write_roots: ["."]
      session_options:
        approval_policy: "never"

Optional environment variables:

• MISTERMORPH_CODEX_COMMAND
  • override backend executable, default codex
• MISTERMORPH_CODEX_ARGS
  • extra backend args, whitespace-split, appended after app-server
• MISTERMORPH_CODEX_AUTO_APPROVE
  • when set to 1, auto-accept Codex command/file approval requests for the session

Test:

npm run test:codex
