Claude Agent Bridge

MCP bridge for using local Claude CLI as a bounded reviewer and analysis delegate for Codex.

Goals

• Let Codex delegate small, bounded tasks to Claude.
• Keep Codex responsible for final decisions, file edits, commits, deploys, and verification.
• Redact sensitive-looking lines before sending context.
• Save Claude outputs for audit and follow-up review.
• Avoid mixing bridge infrastructure experiments into work repos.

Tools

• claude_status: check delegation state.
• claude_set_enabled: enable or disable delegation.
• claude_ask: ask Claude for bounded analysis with optional files.
• claude_review_diff: ask Claude to review current git diff or selected paths.
• claude_read_result: read saved Claude output.

claude_status also reports whether the local claude executable can be found and queried for its version. Delegation runs Claude Code in non-interactive print mode (claude -p) so Codex can capture stdout, but it now injects the claude-reviewer custom agent with --agents and selects it with --agent. Use --no-agent only for troubleshooting.

Install Into Any Repo

Codex CLI Plugin Install

For Codex CLI, add this repository as a marketplace first, then install the plugin from that marketplace:

codex plugin marketplace add https://github.com/pinkpanther7929/claude-agent-bridge
codex plugin add claude-agent-bridge@claude-agent-bridge

codex plugin add claude-agent-bridge@https://github.com/... does not work because plugin add expects plugin@marketplace-name, not a Git URL.

The repository root is a marketplace. The plugin package lives under plugins/claude-agent-bridge.

After install, open a new Codex session. The plugin manifest contributes the Claude MCP server automatically; no separate setup script is required for normal plugin use.

Update later with:

codex plugin marketplace upgrade
codex plugin add claude-agent-bridge@claude-agent-bridge

Or from a local clone:

.\scripts\update-codex.ps1

Start a new Codex session after updating so changed MCP tools and skills are loaded.

Codex Config Fallback

Use this only when you want to register the MCP server directly in ~/.codex/config.toml without using the plugin system:

git clone https://github.com/pinkpanther7929/claude-agent-bridge D:\claude-agent-bridge
cd D:\claude-agent-bridge
.\scripts\install-codex.ps1

Restart Codex after registration. Codex will start the MCP server automatically.

VS Code UI

For VS Code Agent Plugin source install, point the UI at the plugin package folder:

1. Open the Command Palette.
2. Run Chat: Install Plugin From Source.
3. Enter or select plugins/claude-agent-bridge from a local clone.
4. Open a new chat/workspace session after the plugin installs.

The plugin contributes the claude_delegate MCP server and starts it with the current workspace as the default working directory.

For one-off local setup without installing a plugin, use the Command Palette flow MCP: Add Server, choose a stdio server, and point it at:

python -X utf8 <path-to-this-repo>/mcp/claude_mcp_server.py

Scripted Setup

Clone this bridge once, then install it into any repo/workspace with one command:

git clone https://github.com/pinkpanther7929/claude-agent-bridge D:\claude-agent-bridge
python D:\claude-agent-bridge\scripts\install_mcp_config.py D:\your-repo

git clone https://github.com/pinkpanther7929/claude-agent-bridge ~/claude-agent-bridge
python ~/claude-agent-bridge/scripts/install_mcp_config.py ~/your-repo

The installer creates or updates <your-repo>/.mcp.json and preserves existing MCP servers. If claude_delegate already exists with different settings, pass --force to replace only that server entry. The file is written as UTF-8 without a BOM so JSON parsers can read it reliably.

Open a new Codex session from D:\your-repo after installing. The Claude tools will use that repo as their default workspace, including diff review and saved outputs under .tmp/claude_delegate.

Dry-run and JSON output are available for automation:

python D:\claude-agent-bridge\scripts\install_mcp_config.py D:\your-repo --dry-run --json

Local Checks

python -m py_compile scripts\claude_delegate.py scripts\install_mcp_config.py mcp\claude_mcp_server.py
python -X utf8 -m json.tool .agents\plugins\marketplace.json
python -X utf8 -m json.tool plugins\claude-agent-bridge\.mcp.json
powershell.exe -NoProfile -File scripts\install-codex.ps1 -ConfigPath .tmp\codex-test.toml
python -m unittest discover -s tests
python scripts\claude_delegate.py status --json
python scripts\claude_delegate.py --prompt "Build prompt only." --dry-run --json

Plugin manifest validation uses the Codex plugin creator validator, which requires PyYAML in the active Python environment.

Actual Claude delegation may need to run outside the managed Codex sandbox:

python scripts\claude_delegate.py --task second-opinion --prompt "Reply with exactly: OK" --timeout-seconds 30 --json

Safety Rules

• Do not send secrets, tokens, webhooks, passwords, API keys, or tickets.
• Do not ask Claude to edit files, run live operations, commit, push, or deploy.
• Pass only the smallest useful diff, file excerpt, or log excerpt.
• Treat Claude output as review input, not authority.
