No copy-paste install info for "mcp-everything" yet — see the docs or source repo.
Connect to mcp-everything and verify that tools, resources, prompts, and sampling can all be discovered and invoked correctly. Then give me a compatibility test report.
A compatibility report grouped by protocol feature, showing what works and what fails.
I just updated my MCP client. Use mcp-everything to rerun protocol feature tests and list any parts that may have regressed compared with the previous version.
A regression test summary indicating whether each protocol capability still works after the update.
Use mcp-everything to specifically test my client's support for prompts and sampling, and summarize any issues found.
A focused test result and issue list for prompts and sampling support.
Developers can use this test server to verify whether protocol features such as tools, resources, prompts, and sampling work as expected after implementing an MCP client. It helps catch implementation gaps early during integration.
After upgrading the protocol layer, SDK, or message handling logic, teams can rerun feature-wide tests with this server to confirm no compatibility regressions were introduced. This makes it easier to pinpoint which protocol area is failing.
When establishing a testing baseline for an MCP client, this server can act as a standard target covering multiple protocol capabilities. Product and engineering teams can also use it to reproduce issues and debug against expected behavior.
It is a test MCP server designed to exercise multiple protocol features, including tools, resources, prompts, and sampling, so developers can validate client implementations.
It is best suited for developers and testers building or maintaining MCP clients. It is also useful for teams doing compatibility checks, integration testing, or regression testing.
