MCP Resource Patterns

Resources are read-only, URI-addressable data. Get them right and your server feels like a filesystem the agent can browse.

When to Use

• Deciding whether a read operation should be a tool or a resource
• Exposing hierarchical data (files, tickets, logs) to an agent
• Implementing live-updating data via subscriptions
• Designing URI schemes for a new MCP server

Tool vs Resource vs Prompt
