SelectheBestTool — Agent Architecture for Tool Selection

An agent architecture (with a simple custom MCP server) where a main agent that knows nothing about tools declares its intent dynamically, and the system finds the appropriate tool. It has three core components: the Main Agent, a Tool Registry that stores tool schemas in JSON, and a Tool Selector that bridges the two.

Highlights

• An Intent Parser extracts keywords, category, action and target from the query.
• A Capability Scorer combines exact, partial, category, description and semantic matching (HyDE or standard semantic search).
• Parameter validation (types, enums, regex) plus a low-confidence fallback mechanism.
• Automatically discovers tools from the tools/ directory via a ToolAutoLoader.
• Compares standard semantic search against HyDE for tool retrieval.
