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.

enabled and shared were hand-maintained in 24 roles and wrong in both
directions. Both now resolve from the mcp_consumer edges already declared
in meta/services.yml: a server takes the consumers it admits, a client
takes the servers that admit it, and the pair renders as "'peer' in
group_names or ...", or False when no peer is admitted at all. setdefault
keeps meta/mcp.yml and meta/variants.yml as the override channel, so
pinning either key still wins.
The resolved block replaces the mapping instead of being written into it.
_build_role_base_config parks the YAML cache's own object under mcp, so an
in-place setdefault injected the derived keys into every later raw read and
made test_mcp_schema pass alone but fail in a directory run.
The derivation keys on peer presence, never on a peer's own value: a
re-entrant read under _RENDER_GUARD returns the unrendered dict.
Four lints now ask the resolver instead of reading meta/mcp.yml, which they
could not do while the key was hand-written. That is what exposed the eleven
missing hostile-path specs the previous commit closed.
Carries one change that belongs to the WordPress probe but shares a file
with this one: the tool allowlist moves to the hyphenated names the adapter
actually serves.

allowed_consumers was twenty hand-kept lists of which fourteen were identical, so every new client meant an edit in every provider. A client now declares services.<own-entity>.mcp_consumer: true once and a provider refuses one with mcp_consumer: false, which is also what tells a deliberate exclusion apart from a forgotten entry.
The group_names-gated consumer entries give the inventory resolver the co-deploy edge meta/mcp.yml never had: one of sixty-nine matrix rounds carried an MCP client before, twenty-three role/round pairs do now. bond 0.5 keeps the clients out of round 0 so the host memory budget still holds.
BREAKING CHANGE: meta/mcp.yml no longer accepts allowed_consumers; declare services.<entity>.mcp_consumer on the client instead.

The move left every relative path pointing one level short. Most are
links, but the generator's REPO_ROOT is not: with parents[5] it resolves
to docs/contributing/, ROLES_DIR matches nothing, and the report is
written empty instead of the run failing.
The block sat under services but never behaved like a service. A service has
exactly one providing role, declared with provides, so the registry can map the
key to that role and consumers bind their flag to its presence. No role declares
provides: mcp. There are seventeen providers and the pairing is done by
allowed_consumers inside the block itself.
Every rule that enforces the service model therefore needed an exemption for it:
a shared-provider suppression in fourteen roles, a playwright-service-flag
suppression, and two freshly added exemptions in the dynamic-flag and
variants-static-override checks. Four independent rules, four escape hatches,
one cause. They are all gone now, together with a bond key that only the
resource budgeter reads and only for entries under services, and a wordpress
addon bridge that pointed at a service block that no longer exists.
The block moves to meta/mcp.yml. The applications loader maps meta/<name>.yml to
applications.<app>.<name> generically, so the move needs no wiring; the file
takes the same shape as meta/rbac.yml. Every config path follows, the variant
overrides are lifted out of their services map, and the vocabulary module leaves
the services package because it no longer describes one. roles_with_service
gains an explicit topic parameter rather than an implicit fallback, so nothing
silently resolves against the wrong container.
Files that are otherwise unrelated to this move are included where the committed
tree would otherwise keep pointing at a path that no longer resolves: thirteen
vars files, eleven playwright env templates and one task file.
Thirty-nine criteria are now ticked against thirteen new pieces of evidence,
strongest among them the five per-server tool counts hermes reported live and the
status-code check passing on every domain with MCP enabled.
Two criteria are reworded rather than ticked. 206 asked a client to restrict the
tool server to the role's group and closed on someone entitled to drive it not
needing to be an administrator; a user's roles list carries no application
context, so that is not what the platform can express today and the text now says
so. 208 allowed both readings of tools.mutating_tools_enabled, which is why two
roles carried opposite values for the same situation; it now states that the
field records intent and the README names the missing enforcement.
The design doc gains the public exposure section, including that the proxy ships
no rate limiting, and why stdio is not deployed.
Nine criteria stay open: two are PR artefacts, three are blocked upstream, and
four need deploys that have not run.

Add a blocker vocabulary so a role whose upstream MCP path this
deployment cannot use says why instead of reporting an absence. Without
it OpenProject reads as "upstream has no MCP", which is false: the server
ships, it is Enterprise-only. A blocker and a served surface are mutually
exclusive, so a role cannot claim both.
Add endpoint.key_credential and endpoint.suffix for servers that address
a session through the URL path. Baserow streams from
{base}/mcp/{key}/sse, and endpoint fields must stay literal, so the
composition belongs in the discovery layer. A server that declares a path
key without a resolvable value is dropped rather than handed to clients
half-built.
Carry the upstream provenance in the role block, so the audit derives it
instead of keeping a second copy.
Require an explicit mutating_tools_enabled: false for a privileged
auth_subject; the rule previously only fired when the key was present and
true, so omitting it slipped an administrator-scoped surface through.
Move the MCP filters into plugins/filter/mcp/ so they stop sharing a name
prefix with their siblings.

Add basic_auth to the MCP auth schema so Jenkins can declare its
HTTP-Basic endpoint through the contract instead of around it.
Introduce the client-side renderers: mcp_authorization builds the
Authorization header per scheme, mcp_tool_server_connections builds the
Open WebUI tool-server entries and drops servers whose scheme it cannot
present, and mcp_renderable_servers filters a server list, since Jinja
select() needs a test and the repo ships no test plugins.
Replace the inline MCP_DISCOVERED_SERVERS Jinja with a mcp_servers
lookup, and carry auth and username per entry so basic_auth consumers can
build their credential.

A role with a Model Context Protocol surface declares one mcp: entry in
meta/services.yml. The vocabulary module owns every allowed value, a hard
lint validates each declaration, and roles_with_service gains an opt-in
direction= kwarg so a client role resolves its servers at deploy time.
The lookup stays backwards compatible: without direction= the entries
keep their original four keys, so the existing dashboard, prometheus and
matomo callers are untouched. With it, each entry additionally carries
transport, auth, auth_subject and an endpoint dict whose port is
resolved from the referenced service's ports.local or ports.internal.
The lint rejects Jinja on MCP-specific fields (only enabled/shared may
carry it) because the static resolver cannot evaluate a templated block,
and it verifies that endpoint.service_key names a service in the same
file whose ports.* actually contain endpoint.port_key.
