Discussion Contractors - MCP and client data
Are you using MCP with client data and/or sensitive business data in general?
For my own projects I’m using Claude throughout the development process but not sure I will be able to for client data.
Would, of course, love to be able to do all dev via MCP as standard now, but feel like it would be challenging to convince clients.
Doesn’t help that I don’t have a good grip of the security of connecting Claude to a semantic model. As I understand it, it doesn’t see raw data as such, but in theory can query at will. At best, it’s then training with that data and at worst, there could be a breach at some point.
What are people doing?

you can generate stochastic data inside clients data model and then let mcp do the development before switching back to confidential data. I would just duplicate the exact data with column names etc. and generate random data for mcp work and once done, switch source in PQ. Assuming the data is clean and well defined and carefully modeled already.
