• src/index.ts:166-223 (handler)

  The "indic_ner" tool is dynamically registered and handled by this function, which fetches the registry and dispatches the request based on the tool name.

  server.setRequestHandler(CallToolRequestSchema, async (request) => {
    const { name, arguments: args } = request.params;
  
    let registry: Registry;
    try {
      registry = await fetchRegistry();
    } catch (error) {
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify({ error: "Failed to fetch tool registry", detail: String(error) }),
          },
        ],
      };
    }
  
    const tool = registry.tools.find((t) => t.name === name);
    if (!tool) {
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify({
              error: `Tool '${name}' not found`,
              available_tools: registry.tools.map((t) => t.name),
            }),
          },
        ],
      };
    }
  
    try {
      const result = await callTool(tool, args as Record<string, unknown>);
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(result, null, 2),
          },
        ],
      };
    } catch (error) {
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify({
              error: "Tool call failed",
              tool: name,
              service: tool.service,
              detail: String(error),
            }),
          },
        ],
      };
    }
