MCP is an open protocol that standardises how AI applications connect to tools and data sources, so a system exposed once can be used by many AI apps.

In plain words
Think of it as a common plug. You wrap a system — CRM, docs, database — in an MCP server that describes its tools and data; any compatible AI host (assistant, IDE, your own app) can then use it without custom glue code.
When it matters to you
- Several AI apps need the same internal systems
- Building agents with clean system boundaries
- Offering your product to customers’ AI tools
Common pitfalls
- Installing third-party servers without review
- Servers acting as super-users instead of the user
- No audit of tool calls
