Cursor generates. MegaLens reviews.
Cursor writes the code. MegaLens has AI models from other companies review it.
Why Cursor Users Need MegaLens
Cursor supports many models and parallel subagents. MegaLens adds a separate review from models at other companies, and shows where they disagree.
Writing code and reviewing it are different jobs. When the same model does both, it is checking its own work.
Separate reviews, compared. MegaLens selects up to four models for parallel review and reports where they disagree.
"Access Is Not a Pipeline"
Many models being available is not the same as several models checking the same code.
Having many engineers on call is not the same as having several of them read the same diff.
A review from outside your editor. MegaLens selects up to four models from other companies to review the same code.
How It Works
Write code in Cursor normally.
Trigger MegaLens review via MCP: megalens_debate.
MegaLens selects up to four models to look for security, logic and performance problems.
A final check filters the findings and returns a structured report. Each result names the models that actually took part.
Cursor applies fixes based on findings.
Setup
Quickest way: run the setup wizard. It needs Node.js 18 or later. It detects Cursor and writes the config for you. Pasting the config by hand needs nothing installed.
npx megalens-mcp setup
Detects Cursor, asks for your token, and writes the config below automatically. Or paste it yourself into .cursor/mcp.json:
{
"mcpServers": {
"megalens": {
"url": "https://megalens.ai/api/mcp?ide=cursor",
"headers": {
"Authorization": "Bearer ml_tok_your_token_here"
}
}
}
}Replace ml_tok_your_token_here with your own token — keep the word Bearerand the space after it. Pasting the token without "Bearer " in front is a common mistake. Get your token at megalens.ai/app/settings/mcp.
Nothing to install
MegaLens runs on our servers. Cursor talks to it over HTTPS, so there is nothing to install on your machine: no Node, no npx, no local binary. Paste the block above and you are done.
Cursor only reads this file at startup. After saving it, quit Cursor completely and open it again. Reloading the window is not enough. Setup wizard source: github.com/megalens/mcp.
Honest Limitations
- •
MegaLens runs as an MCP server but cannot control Cursor's behavior.
- •
A review takes a few minutes. It is not for autocomplete.
