Q:

MySQL: Can stored procedure information be extracted from the information schema? 

Is it possible to retrieve stored procedure information like name, parameter nane/position/type from the Information Schema in MySQL or possible in some other way? 

A:

You can get a lot of information, including the name, from INFORMATION_SCHEMA.ROUTINES.   See the MySQL Manual for details.  
The parameter information would be contained in the INFORMATION_SCHEMA.PARAMETERS table, but this table is not available in MySQL, so I'm not sure that you can get that information from INFORMATION_SCHEMA. 
If you just need the argument list, you can select the procedure names from INFORMATION_SCHEMA.ROUTINES then get the CREATE PROCEDURE statements for each of them using SHOW CREATE PROCEDURE.   If you just need the arguments and types, you should be able to parse them without too much trouble.
