• src/server/McpServer.ts:99-124 (handler)

  Handler function for the 'server_info' tool. It iterates over registered database adapters, collects their info, and returns a JSON string containing server name, version, transport type, list of adapters, and tool filter summary.

      () => {
          const adapterInfo = [];
          for (const [id, adapter] of this.adapters) {
              adapterInfo.push({
                  id,
                  ...adapter.getInfo()
              });
          }
  
          return {
              content: [{
                  type: 'text' as const,
                  text: JSON.stringify({
                      name: this.config.name,
                      version: this.config.version,
                      transport: this.config.transport,
                      adapters: adapterInfo,
                      toolFilter: {
                          raw: this.toolFilter.raw,
                          enabledCount: this.toolFilter.enabledTools.size
                      }
                  }, null, 2)
              }]
          };
      }
  );

• src/server/McpServer.ts:95-124 (registration)

  Registration of the 'server_info' tool on the MCP server using the deprecated server.tool method. Includes name, description, empty input schema, and inline handler function.

  this.server.tool(
      'server_info',
      'Get information about the db-mcp server and registered adapters',
      {},
      () => {
          const adapterInfo = [];
          for (const [id, adapter] of this.adapters) {
              adapterInfo.push({
                  id,
                  ...adapter.getInfo()
              });
          }
  
          return {
              content: [{
                  type: 'text' as const,
                  text: JSON.stringify({
                      name: this.config.name,
                      version: this.config.version,
                      transport: this.config.transport,
                      adapters: adapterInfo,
                      toolFilter: {
                          raw: this.toolFilter.raw,
                          enabledCount: this.toolFilter.enabledTools.size
                      }
                  }, null, 2)
              }]
          };
      }
