  The getVersionHandler function implements the core logic for the 'helius_get_version' tool by calling the Solana RPC getVersion method via Helius client and formatting the response.

  export const getVersionHandler = async (input: GetVersionInput): Promise<ToolResultSchema> => {
    try {
      const version = await (helius as any as Helius).connection.getVersion();
      return createSuccessResponse(`Version: ${JSON.stringify(version, null, 2)}`);
    } catch (error) {
      return createErrorResponse(`Error getting version: ${error instanceof Error ? error.message : String(error)}`);
    }
  }

• src/tools.ts:265-273 (schema)

      required: []
    }
  },
