Everything MCP Server

The protocol reference server — exercises every MCP feature in one place.

Software Development Testing & QA @katateam

10 tools, all read-onlyecho, get-sum, get-structured-content, get-resource-links and 6 more

What it does

The MCP reference test server: one server that exercises the whole protocol surface — tools, prompts, resources, resource links, structured content, progress notifications, logging, sampling, elicitation, and roots. Built for developers implementing or debugging an MCP client rather than for end-user work; if a client handles this server correctly it handles the protocol. Runs locally over stdio.

Example prompts

Call the echo tool and show me exactly what comes back.
Run the long-running operation tool so I can watch progress notifications arrive.
