lerian

Lerian MCP Server provides a documentation-only gateway that connects AI assistants to Lerian documentation, learning resources, and guided code generation for all Lerian products (Midaz, Tracer, Flowker, Reporter, and more). It exposes a single, consistent tool named lerian that AI agents can invoke with parameters like product, operation, topic, language, and useCase to retrieve docs, learning paths, SDK code, or cross-product searches. Because this is a documentation-only mode, no live Lerian API calls are made; the goal is to help users discover and understand Lerian concepts, tutorials, and integration patterns through structured prompts and generated examples. To use it, configure your MCP with the provided lerian entry, restart your AI app, and start asking questions such as what Midaz transaction documentation looks like or how to implement a Tracer integration. The interface emphasizes a uniform, AI-friendly experience across all Lerian products, making it easy to compare features, learn workflows, and generate sample code without touching live services.

Prerequisites:

• Node.js 18+ and npm (or a compatible environment that can run npx)
• Internet access to fetch the MCP server package

Step 1: Install Node.js and npm if not already installed

• macOS/Linux:
  • curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
  • sudo apt-get install -y nodejs
• Windows: download and install from https://nodejs.org/

Step 2: Install the Lerian MCP server via npx (no permanent install required)

• Run in your terminal: npx -y @lerianstudio/lerian-mcp-server@latest

Step 3: Configure your MCP client

• Add the following configuration snippet to your MCP settings (or paste into Claude/ChatGPT/MCP config UI): { "mcpServers": { "lerian": { "command": "npx", "args": ["-y", "@lerianstudio/lerian-mcp-server@latest"] } } }

Step 4: Restart your AI app and begin using the lerian tool. For example, ask about Lerian Midaz documentation and follow prompts to generate code or learn paths.

Tips and considerations:

• This server operates in Documentation-Only mode; there is no API connectivity to Lerian backends.
• You can enable optional logging by extending the MCP config with env vars such as LOG_LEVEL, ERROR_LOGGING, and PERFORMANCE_TRACKING, for example: { "env": { "LOG_LEVEL": "info" } }. Logs default to a local ./logs/ directory when enabled.
• If you want to customize which documentation URL is loaded, you can set LERIAN_DOCS_URL in the MCP configuration under env.
• Ensure you are using Node.js 18+ as required by the server and MCP tooling.
• If the tool doesn’t respond after changes, restart your AI assistant and verify that the MCP is enabled in its settings.
