Give LLM services and MCP servers stable Mattermost-style 26-character IDs so later ABAC policies can attach to a resource that survives rename, reorder, and System Console edits.
Mint IDs on save, carry them through admin config updates (atomic UpdateConfig), and run a one-time store migration that rewrites legacy UUID service IDs and assigns IDs to MCP / embedded / plugin servers.
Reject stale or conflicting identity payloads instead of silently minting a new ID (that would detach any future policy).
This is layer 1 of the ABAC stack and can merge on its own — it does not need the Mattermost 11.10 ABAC platform APIs.
Reviewers: focus on ID reconciliation (config.ReconcileServiceIDs / MCP equivalents), the one-time store.MigrateABACIDs transaction, and that the webapp round-trips IDs on config save without minting extras.
Test Plan
Save a new LLM service and a new remote MCP server in System Console; confirm each gets a 26-character ID in GET /plugins/mattermost-ai/admin/config.
Edit name/URL of an existing service or MCP server without changing identity; confirm the ID is unchanged after save.
Upgrade (or activate against) a config that still has UUID service IDs; confirm they are rewritten once and fallbackServiceID references are remapped. Automation that hard-coded the old UUIDs must re-read admin config.
Submit a stale/corrupt payload that tries to swap an existing service's ID; confirm the save is rejected.
make check (or at least make test for ./config ./store ./api ./mcp plus webapp unit tests for services/MCP config).
Release Note
Added durable Mattermost-style 26-character IDs for LLM services and MCP servers. Existing UUID service IDs are rewritten once on upgrade; automation that hard-coded those UUIDs must re-read GET /plugins/mattermost-ai/admin/config.

📝 Walkthrough
Walkthrough
The change adds stable service and MCP server IDs, atomic configuration updates, ABAC identity migrations, targeted plugin administration patches, per-request MCP access checks, vector-index rebuild handling, channel auto-reply APIs, and server-assigned identifiers in the web console.
Changes
Stable identities and persistence
Layer / File(s)
Summary
Identity contracts and reconciliation config/mcp_config.go, config/service_ids.go, config/legacy_migrations.go
Service and MCP server IDs now use stable Mattermost-style identities. Configuration reconciliation preserves stored identities and rejects duplicate IDs.
Atomic storage and ABAC migration store/*, server/abac_id_migrations.go, server/main.go, server/legacy_bot_migration.go
Configuration writes now support atomic transformations. ABAC migrations update IDs and references with locking, markers, rollback handling, and activation integration.
MCP runtime and plugin administration mcp/*, api/api_admin.go, api/api_bridge_mcp.go
MCP access checks filter denied servers and tools. Plugin state distinguishes live registrations from persisted orphans. Plugin administration patches only administrator-owned fields.
Admin, index, and auto-reply APIs api/api.go, api/api_admin.go, server/main.go, webapp/src/client.tsx
The API registers vector-index rebuild and channel auto-reply routes. The server wires channel auto-reply storage and expands index compatibility checks.
Web console configuration handling webapp/src/components/system_console/*
The web console applies server-normalized save responses, preserves MCP IDs during edits, and supports unsaved services and servers without client-generated UUIDs.
This change introduces durable resource identities and updates runtime configuration handling, but the current implementation can leave nodes using stale settings, orphan policies by minting replacement MCP IDs, or expose MCP tools without required per-user access filtering. These correctness and security risks should be fixed before merging.

This file exercises the plugin registry thoroughly, but every NewClientManager call passes nil for accessChecker. The new denial logic in deniedExternalOrigins, dropToolsFromDeniedOrigins, and filterErrorsByDeniedOrigins is therefore untested. Add a table-driven test with a small in-package ServerAccessChecker implementation that denies one remote server, the embedded server, and one plugin server. Assert that denied tools disappear, that denied origin auth errors are stripped, and that servers with an empty ID stay allowed.

GetConfig returns m.getErr, but UpdateConfig ignores it and always runs the transform. Handlers that moved from GetConfig to UpdateConfig no longer exercise the read-failure path through this mock, so a test that sets getErr passes for the wrong reason.

The config object rebuilds MCPServerConfig key by key. This pattern caused the dropped id that this change repairs. Any field added to MCPServerConfig later is silently discarded again on every edit. Spread serverConfig first, then apply only the defaults.

PR has broad, high-quality test coverage for ID reconciliation, atomic config saves, and API handlers, but the ABAC filtering helpers in mcp/client_manager.go (deniedExternalOrigins, dropToolsFromDeniedOrigins, filterErrorsByDeniedOrigins) lack any unit tests with a non-nil ServerAccessChecker.
Add table-driven tests covering nil checker (no filtering), denial of remote/embedded/plugin servers, tool dropping, and auth-error suppression for the ABAC filtering code paths.
This PR introduces durable 26-character Mattermost-style IDs for LLM services and MCP servers (embedded, remote, plugin) as the foundation for ABAC policies. The production changes span config validation, atomic config updates, store migrations, API handlers, MCP client manager access control, and webapp UI round-trips.
Production changes and test coverage:
config/service_ids.go (new) — ValidateServiceIDUniqueness
Covered by config/service_ids_test.go: tests for unique IDs, empty IDs ignored, and duplicate IDs returning an error.
config/mcp_config.go — ReconcileMCPConfigIDs, ValidateMCPServerIDUniqueness, ReconcileEmbeddedMCPServerID, ServerIDByOrigin, OriginByServerID
Covered by config/mcp_config_test.go: exhaustive table-driven tests for all reconciliation and ID-map behaviors, including cross-kind ID conflicts, carried-forward plugin rows, and "stale next plugin" attack scenarios.
config/legacy_migrations.go — generateServiceID, MigrateServicesToBots now emit model.NewId()
Covered by config/legacy_migrations_test.go: new TestGenerateServiceID test and assertion that migrated IDs are valid 26-char Mattermost IDs.
api/api_config.go — mintEmptyAdminIDs, atomic handleSaveConfig via UpdateConfig, returns normalized config body, 409/400 error paths
Covered by api/api_config_ids_test.go (594 lines, new file): tests for mint-on-write, stable IDs on round-trip, 409 on duplicate incoming IDs, 400 on legacy UUID IDs post-migration, plugin server rows preserved, cross-kind conflict rejection. Also covered by api/api_config_test.go and api/audit_middleware_test.go which verify the behavior change when GetConfig fa
Suggestions
The overall test coverage is strong and comprehensive, especially for the ID reconciliation logic, atomic config saves, and API handler changes. The primary gap is:
ABAC filtering helpers in mcp/client_manager.go: Add unit tests for deniedExternalOrigins, dropToolsFromDeniedOrigins, and filterErrorsByDeniedOrigins using a stub ServerAccessChecker. Test cases should cover: a nil checker (no filtering), a checker that denies a remote server (tools dropped, auth errors suppressed), denying the embedded server, denying a plugin server, and a mix of allowed/denied servers. These functions are ready to use in the current PR and their correctness is not verified by any existing test.
store/id_migrations_test.go: Confirm migration tests cover the UUID-to-26-char rewrite for services and the assignment of IDs to previously ID-less MCP servers (embedded, remote, plugin), as well as idempotency (running migration twice produces no change).
To override, comment /test-analysis-override <reason> after verifying tests are adequate or not required.
Introduce stable ABAC policy identities for services and MCP servers, with
atomic UpdateConfig, ID migrations, and admin mint/carry so IDs survive edits.

The plugin-server ID is already persisted before PublishConfigUpdate; returning that error skipped RegisterPluginServer and left the local node unregistered.

Empty ids on PUT are creates, uniqueness is incoming-only, and IDs mint
on write rather than GET. One migration marker; UUID format stays 400.

A follower that waits on the migration lock sees Migrated=false and
must still read the winner's remapped service/MCP IDs before EnsureBots.

Summary
UpdateConfig), and run a one-time store migration that rewrites legacy UUID service IDs and assigns IDs to MCP / embedded / plugin servers.This is layer 1 of the ABAC stack and can merge on its own — it does not need the Mattermost 11.10 ABAC platform APIs.
Reviewers: focus on ID reconciliation (
config.ReconcileServiceIDs/ MCP equivalents), the one-timestore.MigrateABACIDstransaction, and that the webapp round-trips IDs on config save without minting extras.Test Plan
GET /plugins/mattermost-ai/admin/config.fallbackServiceIDreferences are remapped. Automation that hard-coded the old UUIDs must re-read admin config.make check(or at leastmake testfor./config ./store ./api ./mcpplus webapp unit tests for services/MCP config).Release Note
