Using Polydev with Cline

Get multi-model AI perspectives directly in Cline (VS Code/Cursor extension). When you need different viewpoints on a bug, architecture decision, or code review, Polydev queries multiple AI models in parallel.

Works across all IDEs: Polydev uses the universal Model Context Protocol (MCP) standard. The same MCP server powers Cline, Claude Code, Cursor, Windsurf, and Codex CLI. Just add it to your MCP config and mention "polydev" or "perspectives" in any prompt.

Install in 60 seconds

1 Install Polydev (requires Node.js):

npm install -g polydev-ai

2 Login from any terminal — opens your browser and saves your token automatically:

polydev-ai login

Or get your token manually from polydev.ai/dashboard/mcp-tokens

3 Open Cline settings: Click the gear icon → "MCP Servers" → "Configure"

4 Add Polydev to your Cline MCP config:

{
  "mcpServers": {
    "polydev": {
      "command": "npx",
      "args": ["-y", "polydev-ai@latest"],
      "timeout": 400
    }
  }
}

If you got your token manually instead of using polydev-ai login, add an env block: "env": { "POLYDEV_USER_TOKEN": "pd_xxx" }

5 Click "Done" and verify Polydev appears in the MCP Servers list with a green indicator

What Polydev adds

MCP Tool

get_perspectives — queries multiple AI models in parallel for diverse viewpoints

Response time

10-40 seconds (parallel queries to multiple providers)

Use cases

Debugging, architecture decisions, code reviews, security analysis

Example: useEffect debugging

In Cline chat, type: Use polydev to help answer: What are common causes of React useEffect infinite loops?

Cline processes the request and queries multiple AI models

How to use it

Just mention "polydev" or "perspectives" in your prompt. Cline's agent will call the get_perspectives MCP tool — the same tool that works in every MCP-compatible IDE:

Debugging

"Use polydev to debug this infinite loop"

Architecture

"Get perspectives on: Redis vs PostgreSQL for caching?"

Code review

"Use polydev to review this API for security issues"

Cline-specific tips

Auto-approve the tool

In MCP Servers settings, enable auto-approve for get_perspectives to skip confirmation prompts.

Works with @file mentions

Combine Polydev with Cline's @file mentions for context-aware multi-model consultation.

Increase timeout

Add "timeout": 400 to your MCP server config. Polydev queries multiple AI models which can take a few minutes for complex prompts.

Auto-Invocation with Custom Instructions

Make Cline automatically consult Polydev when you're stuck. Add this to Cline's Custom Instructions (Settings → Custom Instructions), or create a .clinerules file in your project root:

# Auto-Invoke Polydev for Multi-Model Perspectives

When the user encounters any of these situations, automatically
use the polydev MCP tool (get_perspectives) to consult multiple
AI models before responding:

1. User says "stuck", "confused", "not sure", or "can't figure out"
2. Comparison questions: "Should I use X or Y?"
3. Security or code review requests
4. After 2-3 failed debugging attempts
5. Architecture or design decisions
6. Performance optimization questions

Example: If user says "I'm stuck on this auth bug", call
get_perspectives with the problem context before answering.

Tip: The .clinerules file works per-project. For global rules across all projects, use Cline Settings → Custom Instructions.

Troubleshooting

MCP not showing up?

Check JSON syntax in your config file. Ensure proper commas and quotes. Try clicking "Restart Server" in the MCP Servers panel.

Token not found?

Verify your token starts with pd_ and is correctly set in the env section.

npx path issues?

Use the full path in your config. Find it with:

which npx

Slow responses?

Multi-model queries take 10-40 seconds since they call multiple APIs in parallel.
