Single-Tool MCP Server

Example Use Cases

• 1

  Expose a simple text-processing utility (e.g., word count) as an MCP tool without building a full server.

• 2

  Generate random strings or other small data outputs using a one-line or short JavaScript expression (top-level await supported).

• 3

  Rapidly prototype and share single-purpose commandable tools by specifying parameters and a script via command-line configuration.

Description

one-mcp provides a lightweight way to define and run single-tool MCP servers via simple command-line configuration (examples use npx). Users declare tool name, parameters, and a JavaScript expression (supports top-level await) to implement the tool logic, enabling rapid prototyping of small utilities without writing full server code. It is useful for creating tiny, focused endpoints for text processing, random data generation, and other quick computations.
