What the term really means
Model Context Protocol is an open standard for connecting AI applications with data, tools and reusable resources.
How it works in practice
MCP standardises how an AI application discovers tools and resources so every integration does not need a separate proprietary interface.
The decision to make before implementation
An MCP server should expose only required capabilities, describe parameters accurately and isolate user data.
How to verify that it works
Control the server registry, tool provenance, permissions, call logs, schema versions and behaviour after connection loss. Compare results with an agreed baseline and review routine cases, difficult exceptions and human hand-offs separately. A practical MCP test should have an owner, a review date and a recorded example of an outcome the team will not accept.
The PAR HOUSE Agency approach
We approach MCP from the workflow rather than a tool demonstration. An MCP server should expose only required capabilities, describe parameters accurately and isolate user data. We then build a small measurable scope, record assumptions and expand only after quality review.
