MCP becomes most useful when it is treated as an interface layer rather than a bag of plugins. Each connector should make a piece of context addressable, auditable, and reusable.
Working Thesis
A personal knowledge site needs three layers: source material, interpretation, and tool access. MCP sits between those layers and gives agents consistent handles for external systems.
Practical Rules
- Document the shape of each tool call.
- Connect tools to skills and reading trails.
- Keep public website entries descriptive; do not expose live private tool execution.
