SuperLenz

Lenz — from Latin "lenticula" (lens). A super-powered lens that magnifies the truth. SuperLenz searches multiple sources, cross-verifies every claim through 10+ rounds, and delivers only credible, validated research.

High-credibility research automation with multi-source cross-verification (10+ rounds)

A Model Context Protocol (MCP) server that automates research tasks with a focus on credibility and accuracy. It performs automatic searching, collection, cross-verification (10+ rounds), and saves results to your preferred storage.

Features

• Multi-Source Search: Web search (Brave, Exa), academic papers (arXiv, Semantic Scholar), GitHub

• 10-Round Cross-Verification: Keyword overlap matching (rounds 1-4), conflict detection (5-8), optional LLM verification (9-10)

• Credibility Scoring: Authority assessment, temporal validation, source weighting

• Flexible Storage: Markdown (default), JSON

• Plugin Architecture: Extensible storage and search providers

Requirements

• Node.js >= 18.0.0

• Any MCP-compatible client

Environment Variables

SuperLenz reads these from the system environment. If a key is available, the corresponding feature is automatically enabled. No key is strictly required — arXiv search is always available.

Tip: If your MCP client supports an "env" field, you can pass keys there instead of setting them system-wide.

MCP Client Configuration

All examples below use npx — no prior installation required.

Claude Desktop

No CLI — edit the JSON config file directly.

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "superlenz": {
      "command": "npx",
      "args": ["-y", "superlenz"]
    }
  }
}

Claude Code (CLI)

Option A — CLI command:

claude mcp add superlenz -- npx -y superlenz

Management commands:

claude mcp list              # list registered servers
claude mcp remove superlenz  # remove a server

Option B — JSON config:

Edit ~/.claude/settings.json (or .claude/settings.json at the project root):

{
  "mcpServers": {
    "superlenz": {
      "command": "npx",
      "args": ["-y", "superlenz"]
    }
  }
}

Cursor

No CLI "add" command — edit the config file or use the Settings UI.

Open Settings > MCP Servers and add, or edit .cursor/mcp.json (project) / ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "superlenz": {
      "command": "npx",
      "args": ["-y", "superlenz"]
    }
  }
}

Management commands (in Cursor's terminal):

cursor agent mcp list                # list servers
cursor agent mcp enable <id>         # enable a server
cursor agent mcp disable <id>        # disable a server

VS Code (Copilot)

Option A — CLI command:

code --add-mcp '{
  "name": "superlenz",
  "command": "npx",
  "args": ["-y", "superlenz"]
}'

Option B — JSON config:

Edit .vscode/mcp.json in your workspace. Note: VS Code uses the "servers" key (not "mcpServers").

{
  "servers": {
    "superlenz": {
      "command": "npx",
      "args": ["-y", "superlenz"]
    }
  }
}

Or add to VS Code settings.json under "mcp.servers".

Gemini CLI

Option A — CLI command:

gemini mcp add superlenz npx -y superlenz

Management commands:

gemini mcp list              # list registered servers
gemini mcp remove superlenz  # remove a server

Option B — JSON config:

Edit ~/.gemini/settings.json:

{
  "mcpServers": {
    "superlenz": {
      "command": "npx",
      "args": ["-y", "superlenz"]
    }
  }
}
