The MCP self-test exists to answer a narrow but important question: can this provider surface see and call the AxiOwl MCP tools?
Messaging fails in confusing ways when MCP is not registered correctly. A provider may receive the visible message, understand the instruction, and still be unable to reply because the AxiOwl tool is missing. That is not a provider reasoning failure. It is an installation or configuration failure.
AxiOwl's MCP self-test gives support a direct way to check the registration boundary.
The test should initialize the MCP server in the same mode the provider expects and verify that the tool contract is available. It should fail loudly when the host, provider, or configuration is wrong. A quiet pass with missing tools is worse than an obvious failure.
This is useful after install, reinstall, provider updates, and rename refactors. MCP config can become stale. Old product names can remain in provider settings. A provider session can keep old state until restarted.
The self-test is not the whole provider test. A provider can pass MCP registration and still fail delivery. But it removes one major uncertainty. If the provider cannot see AxiOwl MCP tools, reply tests will not work.
Good provider validation should layer checks:
1. Install selected feature.
2. Confirm MCP registration.
3. Discover target session.
4. Send a message.
5. Receive a reply.
6. Verify sender identity.
MCP self-test is the second layer. It proves the reply channel exists before the user relies on it.
