The contract check ran as an Ansible task in the middle of every provider deploy, and the two client checks ran the same way. A test that is part of the deploy cannot be run without deploying, cannot be re-run on its own, and reports its verdict as a deploy failure. Twenty-seven task files lose 491 lines to this.
It is now what it always was. Each provider ships files/test/test.sh, templates/test.env.j2 and meta/tests.yml, and test-e2e-cli stages one shared harness beside it: run.sh drives contract.sh in a throwaway container on the provider's own network, then isolation.sh for adapter-fronted providers. The read probe each provider offers moved from the calling task into meta/mcp.yml next to the allowlist it must satisfy, and the schema now rejects a read probe naming a tool outside that allowlist.
The bearer the test presents is the one a client resolves through mcp.credential, via the new mcp_client_bearer lookup over resolve_credential, which moved to utils.roles.applications.mcp so it is the same function mcp_servers renders every client connection with. The probe presented whatever the calling role passed, which for the fifteen adapter-fronted providers is a different secret than any client holds.
Sidecar isolation is read from the engine rather than measured inside the container, so it no longer needs a delegation to the node holding the task: attachment is compared by network name, which drops the gwbridge special case, and a swarm worker says it cannot measure instead of skipping silently.
Retrying is bounded by wall clock against MCP_DEADLINE_SECONDS, which scales through the same lookup('timeout') as the harness budget it has to stay under. A flag that is neither true nor false aborts rather than reading as off.
mcp-provider-probe becomes mcp-provider-cli-test: an enabled provider must ship the test rather than include the task. mcp-probe-bearer becomes mcp-adapter-bearer, tying ADAPTER_BEARER to the declared credential key now that no probe include carries it. A new integration test renders the shared env template for every provider through Ansible's own templar, so a later change to it breaks visibly instead of poisoning twenty deploys quietly.
Hermes and OpenClaw keep their client-side proof as CLI tests of their own.

"""Lookup ``mcp_client_bearer``: the secret a client presents to a provider.
|
|
|
|
"{{ lookup('mcp_client_bearer', 'web-app-gitea') }}"
|
|
-> the bearer an admitted client sends, or "" when none is minted yet
|
|
|
|
Which secret that is depends on ``mcp.credential.source``: an adapter fronts
|
|
its upstream and issues its own bearer under the role's ``secrets.credentials``,
|
|
while a native or plugin provider hands out the token its principal holds in
|
|
the store. Reading the wrong one yields a secret that exists, authenticates
|
|
something, and is rejected by the endpoint under test.
|
|
|
|
The choice is not repeated here: it is ``resolve_credential``, the same
|
|
function ``mcp_servers`` renders every client's connection with, so a test
|
|
built on this lookup measures the credential the deployment actually ships.
