MCP server for safe AI agent runtime upgrades — version-aware regression catalog, pre/post snapshot diffing, step-by-step upgrade + rollback guides. Captures deployment state before upgrade, re-runs detection checks after, surfaces
new_failures(caused by the upgrade) separately fromunchanged_failures(pre-existing) andrecovered(fixed by the upgrade). Read-only by design — never executes the upgrade itself; the operator retains full agency. v1.0 ships with the OpenClaw regression catalog (8 entries grounded in real field reports); the same machinery accepts a custom catalog for any AI runtime via Custom MCP Build adapters. Keywords: AI runtime upgrade, regression detection, safe deployment, version-specific bug catalog, AI agent ops.
Production AI runtime upgrades — OpenClaw, Claude Code, agent harnesses, runtime servers — carry recurring regressions that you only find after upgrading. Recent examples:
on_message. 2026.4.30+ surfaced OOM under sustained 200k-token contexts. The pattern: upgrade on Friday, hit a new failure mode on Tuesday, spend Wednesday-Thursday excavating release notes + field reports.This MCP server moves the regression excavation upfront — before the upgrade, not after — and verifies the post-upgrade state by diffing against a snapshot you took beforehand. Read-only by design: never executes the upgrade itself; the operator retains full agency.

[MCP tools: current_version + available_upgrades]
Current: 2026.4.23
Recommended target: 2026.5.2 (no CRITICAL regressions in path)
Available upgrades:
2026.4.24-.26 HIGH R-73421 Discord-receive breakage
2026.4.27 — clean
2026.4.30 HIGH R-OOM-DURING-LARGE-CONTEXT (unfixed)
2026.5.1-.2 HIGH R-OOM + R-LOG-ROTATION-DROP (unfixed)
> claude: walk me through upgrading to 2026.4.27.
[MCP tool: upgrade_guide]
2026.4.23 → 2026.4.27 — proceed with mitigations applied.
Applicable known regressions:
R-41372 (HIGH) — Cron --session web-search silent fail.
Mitigation: silentwatch-mcp covers detection until upgrade.
R-73421 (HIGH) — Discord-receive callbacks not firing.
Mitigation: `openclaw skill reload discord` after upgrade.
Pre-upgrade steps:
1. Capture pre-upgrade snapshot (call pre_upgrade_snapshot)
2. Verify backups: cp -r ~/.openclaw ~/.openclaw.backup-$(date +%Y%m%d)
Upgrade steps:
1. openclaw gateway stop
2. openclaw upgrade --to 2026.4.27
3. openclaw gateway start
Post-upgrade steps:
1. Run post_upgrade_verify(snapshot_id=<your-pre-upgrade-id>)
2. openclaw skill reload discord (R-73421 mitigation)
Rollback steps: stop → openclaw upgrade --to 2026.4.23 → restore backup → start.
Confidence: Path includes 2 HIGH regressions but no CRITICAL.
> claude: I just upgraded. Verify it.
[MCP tool: post_upgrade_verify(pre_snapshot_id="snap-...")]
Upgrade 2026.4.23 → 2026.4.27: SUCCESS.
0 new failures, 1 recovered (skills.discord_receive_registered),
0 unchanged failures.
v1.2 — provider-side regression detection. The other half of the upgrade-safety story: when the hosted LLM provider silently changes their model behavior with no upgrade event on your side. Source: Anthropic April 23 2026 post-mortem — Anthropic admitted silently changing Claude Code's default reasoning effort for 5 weeks (Mar 4 → Apr 7) without notification. Verbatim from a Phoenix user asking for the feature in their own community discussions (#10442): "Does Phoenix have a way to detect this kind of silent drift where surface metrics look healthy but the model is actually failing?" And from Om Patel @om_patel5 on X (171K views, 1.3K likes, 195 RTs): "OPUS 4.6 JUST ADMITTED ITS REASONING EFFORT IS SET TO 25 OUT OF 100" — operator extracted the current setting directly from the model. v1.3 backlog idea: add an active-extraction tool that runs scheduled probes ("what is your current reasoning_effort?") + records the model's self-reported settings over time, complementing v1.2's passive latency/response-shape fingerprinting. This server now does the passive part.

openclaw-upgrade-orchestrator-mcpThree things existing tools (vendor changelogs, internal runbooks, generic CI/CD orchestrators) don't do:
Catalog-grounded regression awareness. A generic upgrade tool tells you the version exists. This server tells you which versions have known issues, which fix versions remediate them, and which mitigations apply if you have to use the affected version.
Pre/post snapshot diffing tied to the catalog. The same checks run before + after the upgrade. The diff highlights new_failures (caused by the upgrade) separately from unchanged_failures (pre-existing) and recovered (fixed by the upgrade). No more "did this break in 2026.4.27 or was it already broken?"
Read-only by design. Never runs openclaw upgrade --to ... for you. Never modifies state. Operators retain full agency over the actual upgrade — this server gives them the information to make the decision, then verifies it after they execute.
Built for the production-AI operator who owns OpenClaw deployments and has been through enough upgrade-day fire drills.
| Tool | What it returns |
|---|---|
current_version | Currently-installed version + detection method |
available_upgrades | Newer versions with regression-count flags + recommended target |
pre_upgrade_snapshot | Captures every check's pass/fail state, persists with snapshot_id |
upgrade_guide | Step-by-step plan: pre / upgrade / post / rollback steps + applicable regressions + confidence note |
post_upgrade_verify | Diff post-upgrade against a stored pre-upgrade snapshot — new_failures / recovered / unchanged |
rollback_guide | Recovery plan for a given snapshot — downgrade command + state-restore steps + risk note |
regression_catalog | Full known-regression catalog, optionally filtered to one version |
list_snapshots | All stored snapshots (id + version + summary) |
record_provider_call (v1.2) | Append a single provider API call observation to the fingerprint history |
get_provider_fingerprint (v1.2) | Aggregate fingerprint over a window — call count, latency p50/p95, response-length distribution, distinct models, most-common headers |
detect_provider_regression (v1.2) | Compare current vs baseline window; flag distribution shifts with severity |

After install, run the bundled demo to see the upgrade-orchestrator analyze a representative deployment:
openclaw-upgrade-orchestrator-mcp-demo
You'll see a 5-step walkthrough: current version 2026.4.23, recommended upgrade target 2026.5.2 (heuristically skips broken middle versions), 2 known regressions affecting 2026.4.23 (R-41372 web-search silent fail + R-73421 Discord receive breakage), full 11-step upgrade plan with rollback commands, and pre-upgrade snapshot showing 1 of 6 checks would fail. Read-only — never executes any upgrade. No external I/O, no API keys — safe to run anywhere.

Override via OPENCLAW_VERSION_FILE, OPENCLAW_GATEWAY_CONFIG, OPENCLAW_UPGRADE_SNAPSHOT_DIR. v1.2: also reads/writes provider-call records as JSONL in ~/.openclaw/upgrades/provider-calls.jsonl.

available_upgrades flags every version reachable from current and computes a recommended_target:
For each available version V > current:
applicable_regressions = regressions_in_path(current, V)
has_known_critical = any(r.severity == CRITICAL for r in applicable_regressions)
recommended_target = highest V with has_known_critical == False
regressions_in_path(current, target) includes a regression if:
OpenClaw upgrades atomically (no execution on intermediate versions), so a regression strictly between current and target without affecting either endpoint is NOT included. This avoids over-conservative recommendations.
| Version | Scope | Status |
|---|---|---|
| v1.0 | mock + openclaw-system backends, 8 tools / 3 resources / 2 prompts, 8-entry regression catalog, 6 detection checks, GitHub Actions CI matrix, PyPI Trusted Publishing | ✅ |
| v1.2 | Provider-side regression detection — ProviderCallRecord data model, 3 new tools (record_provider_call, get_provider_fingerprint, detect_provider_regression), upgrade://provider-fingerprint resource, diagnose-provider-regression prompt. Detects passive distribution shifts in latency/response-shape/model-version when the provider silently changes things on their end. Folded in from research-pass-3 P08 candidate after incumbent validation against Phoenix + Langfuse + Galileo | ✅ |
| v1.3 | Catalog auto-fetch from upstream changelog feed; richer detection checks tied to OpenClaw's /healthz endpoint; multi-step upgrade pathing | ⏳ |
| v1.4 | Custom catalog packs (operator can ship internal-only regression entries alongside the canonical catalog); rule-overrides | ⏳ |
| v1.x | Webhook emit on detected regression; integration with CI to gate merges of OpenClaw-version bumps | ⏳ |
If your AI deployment uses a different runtime (custom agent harness, internal fork of OpenClaw, vendor-locked deployment) and you want the same regression-aware upgrade discipline, that's a Custom MCP Build engagement.
| Tier | Scope | Investment | Timeline |
