How to Set Up and Use Waldzell
Waldzell is a monorepo of purpose-built MCP servers from Waldzell AI, covering structured reasoning, coding style guidance, and probabilistic thinking. The flagship server — Clear Thought — provides mental models (First Principles, Occam's Razor, Pareto Principle), design patterns, programming paradigm guidance, structured debugging approaches, and sequential thinking scaffolding. Developers use these servers to inject systematic problem-solving frameworks into Claude Desktop, Cline, Roo Code, or any MCP-compatible client.
Prerequisites
- Node.js 18 or higher
- npm (bundled with Node.js)
- An MCP-compatible client such as Claude Desktop, Cline, or Roo Code
- Git to clone the repository for local builds
Install Clear Thought via Smithery (recommended)
The easiest installation method uses the Smithery CLI to configure Claude Desktop automatically.
npx -y @smithery/cli install @waldzellai/clear-thought --client claudeOr install via npm
Install the Clear Thought package directly from npm for use with any MCP client.
npm install -g @waldzellai/clear-thought
# Or run directly with npx without installing:
npx @waldzellai/clear-thoughtOr build from source
Clone the monorepo and build all servers locally if you want to modify or inspect the source.
git clone https://github.com/waldzellai/waldzell-mcp.git
cd waldzell-mcp
npm install
npm run build --workspacesAdd the server to your MCP client config
Register the Clear Thought server in your Claude Desktop or other MCP client configuration.
Invoke a mental model or debugging approach
Ask Claude to use a specific mental model or debugging approach to get structured, framework-guided reasoning.

Example prompts that leverage Clear Thought's reasoning frameworks.
- "Use first principles thinking to analyze why our API response times are degrading under load"
- "Apply Occam's Razor to this bug: the login form submits but users are not being authenticated"
- "Use the binary search debugging approach to isolate which commit introduced this regression"
- "Walk me through a sequential thinking process to plan the architecture for our new microservice"
- "Apply the Pareto Principle to our backlog — which 20% of tasks will deliver 80% of user value?"Troubleshooting Waldzell
npx @waldzellai/clear-thought fails with package not found
Ensure you have Node.js 18+ installed. Run 'npm view @waldzellai/clear-thought' to confirm the package exists in the npm registry. If it is unavailable, build from source by cloning the repository and running 'npm install && npm run build --workspaces'.
Server starts but reasoning tools are not appearing in the MCP client
Restart your MCP client after updating the configuration. In Claude Desktop, quit and relaunch the app. Confirm the mcpServers block in claude_desktop_config.json is valid JSON with no trailing commas.
Smithery installation fails or times out
Try the manual npm installation instead: 'npm install -g @waldzellai/clear-thought'. Then add the configuration block to your MCP client's config file manually pointing to the globally installed command.
