🆕 Now with CLI-to-CLI Bridge

The new clink (CLI + Link) tool connects external AI CLIs directly into your workflow:

• Connect external CLIs like Gemini CLI, Codex CLI, and Claude Code directly into your workflow
• CLI Subagents - Launch isolated CLI instances from within your current CLI! Claude Code can spawn Codex subagents, Codex can spawn Gemini CLI subagents, etc. Offload heavy tasks (code reviews, bug hunting) to fresh contexts while your main session's context window remains unpolluted. Each subagent returns only final results.
• Context Isolation - Run separate investigations without polluting your primary workspace
• Role Specialization - Spawn planner, codereviewer, or custom role agents with specialized system prompts
• Full CLI Capabilities - Web search, file inspection, MCP tool access, latest documentation lookups
• Seamless Continuity - Sub-CLIs participate as first-class members with full conversation context between tools

# Codex spawns Codex subagent for isolated code review in fresh context
clink with codex codereviewer to audit auth module for security issues
# Subagent reviews in isolation, returns final report without cluttering your context as codex reads each file and walks the directory structure

# Consensus from different AI models → Implementation handoff with full context preservation between tools
Use consensus with gpt-5 and gemini-pro to decide: dark mode or offline support next
Continue with clink gemini - implement the recommended feature
# Gemini receives full debate context and starts coding immediately

Why PAL MCP?

Why rely on one AI model when you can orchestrate them all?

A Model Context Protocol server that supercharges tools like Claude Code, Codex CLI, and IDE clients such as Cursor or the Claude Dev VS Code extension. PAL MCP connects your favorite AI tool to multiple AI models for enhanced code analysis, problem-solving, and collaborative development.

True AI Collaboration with Conversation Continuity

PAL supports conversation threading so your CLI can discuss ideas with multiple AI models, exchange reasoning, get second opinions, and even run collaborative debates between models to help you reach deeper insights and better solutions.

Your CLI always stays in control but gets perspectives from the best AI for each subtask. Context carries forward seamlessly across tools and models, enabling complex workflows like: code reviews with multiple models → automated planning → implementation → pre-commit validation.

You're in control. Your CLI of choice orchestrates the AI team, but you decide the workflow. Craft powerful prompts that bring in Gemini Pro, GPT 5, Flash, or local offline models exactly when needed.

<details> <summary><b>Reasons to Use PAL MCP</b></summary>

A typical workflow with Claude Code as an example:

1. Multi-Model Orchestration - Claude coordinates with Gemini Pro, O3, GPT-5, and 50+ other models to get the best analysis for each task

2. Context Revival Magic - Even after Claude's context resets, continue conversations seamlessly by having other models "remind" Claude of the discussion

3. Guided Workflows - Enforces systematic investigation phases that prevent rushed analysis and ensure thorough code examination

4. Extended Context Windows - Break Claude's limits by delegating to Gemini (1M tokens) or O3 (200K tokens) for massive codebases

5. True Conversation Continuity - Full context flows across tools and models - Gemini remembers what O3 said 10 steps ago

6. Model-Specific Strengths - Extended thinking with Gemini Pro, blazing speed with Flash, strong reasoning with O3, privacy with local Ollama

7. Professional Code Reviews - Multi-pass analysis with severity levels, actionable feedback, and consensus from multiple AI experts

8. Smart Debugging Assistant - Systematic root cause analysis with hypothesis tracking and confidence levels

9. Automatic Model Selection - Claude intelligently picks the right model for each subtask (or you can specify)

10. Vision Capabilities - Analyze screenshots, diagrams, and visual content with vision-enabled models

11. Local Model Support - Run Llama, Mistral, or other models locally for complete privacy and zero API costs

12. Bypass MCP Token Limits - Automatically works around MCP's 25K limit for large prompts and responses

The Killer Feature: When Claude's context resets, just ask to "continue with O3" - the other model's response magically revives Claude's understanding without re-ingesting documents!

Example: Multi-Model Code Review Workflow

1. Perform a codereview using gemini pro and o3 and use planner to generate a detailed plan, implement the fixes and do a final precommit check by continuing from the previous codereview
2. This triggers a codereview workflow where Claude walks the code, looking for all kinds of issues
3. After multiple passes, collects relevant code and makes note of issues along the way
4. Maintains a confidence level between exploring, low, medium, high and certain to track how confidently it's been able to find and identify issues
5. Generates a detailed list of critical -> low issues
6. Shares the relevant files, findings, etc with Gemini Pro to perform a deep dive for a second codereview
7. Comes back with a response and next does the same with o3, adding to the prompt if a new discovery comes to light
8. When done, Claude takes in all the feedback and combines a single list of all critical -> low issues, including good patterns in your code. The final list includes new findings or revisions in case Claude misunderstood or missed something crucial and one of the other models pointed this out
9. It then uses the planner workflow to break the work down into simpler steps if a major refactor is required
10. Claude then performs the actual work of fixing highlighted issues
11. When done, Claude returns to Gemini Pro for a precommit review

All within a single conversation thread! Gemini Pro in step 11 knows what was recommended by O3 in step 7! Taking that context and review into consideration to aid with its final pre-commit review.

Think of it as Claude Code for Claude Code. This MCP isn't magic. It's just super-glue.

Remember: Claude stays in full control — but YOU call the shots. PAL is designed to have Claude engage other models only when needed — and to follow through with meaningful back-and-forth. You're the one who crafts the powerful prompt that makes Claude bring in Gemini, Flash, O3 — or fly solo. You're the guide. The prompter. The puppeteer.

You are the AI - Actually Intelligent.
