MCP Resources
MCP resources are addressable read-only context — files, records, docs — that a client can pull into the model instead of calling a tool.
/ quick answer
Resources are identified by URI and fetched on demand, which keeps large context out of the prompt until it is needed. Use resources for material the model reads (documentation, a spec, a record) and tools for actions it performs. Mixing the two into one giant tool is the most common MCP design mistake.

Why does MCP Resources matter for AI and automation?
MCP resources are addressable read-only context — files, records, docs — that a client can pull into the model instead of calling a tool. It connects to the workflows, prompts and tool stacks linked on this page, so you can move from definition to execution without leaving Onexial.
