via “tool schema registration and discovery via mcp listtoolsrequest”
AI-optimized web search and content extraction via Tavily MCP.
Unique: Implements MCP tool schema registration using setRequestHandler with JSON schemas for each tool's parameters, enabling clients to discover and validate tools without hardcoding tool metadata. Schemas are defined in src/index.ts and returned in ListToolsRequest responses.
vs others: Schema-based tool discovery enables dynamic client UIs and parameter validation, whereas hardcoded tool lists require client updates when tool parameters change.
