What is Model Context Protocol (MCP)?
An open standard that lets AI assistants call external tools.
The Model Context Protocol (MCP) is an open standard for connecting AI assistants (like Claude or ChatGPT) to external tools and data sources. An MCP server exposes a set of tools; the assistant can list and call them to read data or take actions.
CiteTrack ships a built-in MCP server, so you can connect your own assistant and ask it about your AI visibility, or build automations on top, using the plugin as a connector. See Developer API & MCP.
Why — and when — does it matter?
MCP standardizes how an assistant discovers and calls external tools. It is relevant when AI needs controlled access to live data or actions beyond its model context.
How it works
A client connects to an MCP server.
The server advertises tools, resources or prompts.
The model selects a tool and supplies arguments.
The server enforces authorization and executes it.
Structured results return to the model for interpretation.
Worked example
An assistant calls a read-only “get citation trend” tool for the user’s WordPress site instead of asking the user to export a CSV.
How to track and report it
Reporting rule: State the engine, prompt set, market, time window and denominator. A number without scope cannot be reproduced or compared.
Practical playbook
- A client connects to an MCP server.
- The server advertises tools, resources or prompts.
- The model selects a tool and supplies arguments.
- The server enforces authorization and executes it.
- Structured results return to the model for interpretation.
Common mistakes
- Exposing write tools without safeguards
- Returning unstructured oversized results
- Confusing MCP with a model or database

How do you measure Model Context Protocol (MCP)?
Successful authorized tool-call rate. Latency, errors and user-confirmed task completion. Tool success rate = successful valid calls ÷ attempted valid calls × 100
What is a common mistake with Model Context Protocol (MCP)?
Exposing write tools without safeguards. The scope and methodology should be stated before interpreting the result.
