Connecting MCP Servers

Scope MCP servers to the projects that need them instead of dumping every tool into one global runtime.

MCP configuration is most useful when it stays explicit and scoped.

​

Good defaults

Use shared defaults only for truly universal tools. Put project-specific MCP servers inside the project definition so the runtime remains predictable.

​

First things to verify

• command path
• environment variables
• project scope

Most MCP issues come from those three areas, not from the protocol itself.
