MCP
also Model Context Protocol
A standard way to plug tools and data into the model: issue trackers, browsers, docs, databases.
What is MCP?
MCP is a protocol so an agent can call external tools through a shared shape instead of a one-off integration. Servers expose tools and resources; the client (your coding agent) calls them.
Why does MCP matter when vibe coding?
Without MCP you paste tickets and logs by hand. With it the model can read Linear, query a DB, or drive a browser — and also exfiltrate if you wired production. Treat MCP servers like shell access.
How do you do MCP?
Enable only the servers this repo needs. Prefer read-only. Never point an agent at production credentials through MCP “to be helpful.”
How do you ask a model for MCP?
You may use these MCP tools: (list). Read-only. Do not call anything that writes to production. If a tool is missing, ask; do not invent a call.
What goes wrong with MCP?
Installing every MCP server you saw on Twitter. Each one is another blast radius.
