The Toolbox for AI Agents

Give Your AI Agent
a Calculator

Humans and LLMs can both do math—but give either one a calculator and they can do far more complicated math easily, quickly, and more reliably. ClineTools is a curated toolbox of safe, tested tools built and upgraded by enthusiasts to make Cline and other AI agents many times more capable, efficient, quick, reliable, and useful.

"I gave Cline the Code Complexity Analyzer and the Dead Code Detector. It went from making okay refactoring suggestions to catching architectural issues I'd missed for months."

Sarah K.
Senior Developer

"The best part? These tools run locally. No API keys, no usage limits, no data leaving my machine. My agent just has better eyes and hands now."

Marcus R.
Full Stack Engineer

"We plugged the Secret Scanner and Prompt Injection Detector into our CI pipeline. Our AI agents now catch security issues before any human reviewer even sees the PR."

Jamie L.
Engineering Lead

Why Tools Make AI Agents Dramatically Better

An LLM without tools is like a mathematician without a calculator—capable but limited. The right tools don't replace intelligence, they multiply it.

Local-First, Offline-Ready

Most of our tools run entirely on your machine. No API keys, no rate limits, no data leaving your environment. Your agent gets superpowers without the cloud dependency.

Instant Capability Boost

Install a tool and your agent can immediately do things it couldn't before—scan for vulnerabilities, analyze complexity, detect secrets, parse logs, and more.

Security Verified

Every tool undergoes our 4-phase security audit. MCP servers run with broad access—we make sure they earn that trust before you install them.

Works With Any Agent

Built on the MCP standard, these tools work with Cline, Claude Code, Cursor, Windsurf, Aider, and any agent that speaks the Model Context Protocol.

Tutorials for Every Tool

Each tool comes with a guide: how to install it, how your agent will naturally use it, and how you can intentionally direct its use for maximum impact.

Community Built & Upgraded

Built by enthusiasts, tested by the community, improved by everyone. Submit your own tools, suggest improvements, or fork and customize anything.

Local Tools vs. API-Dependent Tools

We prioritize tools that run locally and offline. For every API-dependent tool, we're building a local alternative so your agent never depends on an external service.

LOCAL / OFFLINE

Runs on Your Machine

No internet required. No API keys. No usage limits. No data leaves your environment. Fast, private, and always available.

  • ✓ Code analyzers & linters
  • ✓ Security scanners
  • ✓ File format converters
  • ✓ Git history tools
  • ✓ Documentation generators
  • ✓ Test scaffolding tools
API REQUIRED

Needs an External Service

Some capabilities require APIs today. We list them honestly and we're actively building local alternatives for every single one.

Tools That Reduce Risk at Every Step

Your AI agent has broad system access. These tools act as safety rails—catching vulnerabilities, leaked secrets, and injection attacks before they reach production.

Before the Agent Runs

Audit MCP servers, scan configs, verify permissions. Know exactly what your agent can access before you let it loose.

While the Agent Works

Real-time secret scanning, prompt injection detection, and output validation. Catch problems as they happen.

Before Code Ships

Automated security gates: dependency scans, credential checks, code complexity analysis. Your agent becomes your first reviewer.

Continuous Monitoring

Track tool behavior over time, flag anomalies, and get alerts when dependencies introduce new risks.
