HasMCP’s Dynamic Tool Discovery implements a “Wrapper Pattern.” Instead of exposing every tool directly, the server hides its entire toolset and exposes only three standard discovery tools:

searchTools: Allows the agent to search for relevant tools or toolkits using BM25 (relevance) or Regex (pattern) search.

getToolDefinition: Fetches the full JSON schema for a single specific tool only when the agent decides to use it.

useTool: Executes a tool by name and arguments.
