Openclaw Upgrade Orchestrator

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 from unchanged_failures (pre-existing) and recovered (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.

What it does

Production AI runtime upgrades — OpenClaw, Claude Code, agent harnesses, runtime servers — carry recurring regressions that you only find after upgrading. Recent examples:

• The "claw tax." Anthropic announced standard Claude subscriptions would no longer cover usage through external "claw" harnesses like OpenClaw — forcing those workloads onto metered API billing — without a clean upgrade path. r/AI_Agents thread on the OpenClaw creator suspension (201 pts, April 12 2026) walks through the structural conflict.
• OpenClaw 2026.4.8 brought a CPU-spike bug. 2026.4.23-26 broke Discord 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.
• Claude Code itself has documented compaction failures at 48% context usage (GitHub Issue #23751) and the "1M context window does not work as marketed" complaint (GitHub Issue #35296) — recurring upgrade regressions in the underlying runtime, not just OpenClaw.
• HERMES.md detection (the billing routing bug) is itself an upgrade regression — Anthropic added detection logic that fires false positives, and operators only discover it when they're already $200 deep in unintended API charges.

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?" This server now does.

> claude: has Anthropic regressed something on their end in the last hour?
[MCP tool: detect_provider_regression(provider="anthropic")]

Severity: CRITICAL
provider: anthropic
current_window_hours: 1   sample_count: 50
baseline_window_hours: 168  sample_count: 1000

Alerts:
  [CRITICAL] latency_p95: 3,200ms vs 1,500ms baseline (+113%)
  [HIGH]     latency_median: 1,500ms vs 800ms baseline (+87%)
  [MEDIUM]   response_length_median: 350 vs 800 (-56%)

Summary: anthropic: 3 alerts — worst is CRITICAL on latency_p95:
latency_p95 is 113% higher than baseline (3200 vs 1500) — likely regression

> claude: capture the next 100 calls so I can see the fingerprint over time.
[MCP tool: record_provider_call (called by your LLM-client shim, once per response)]

After enough calls accumulate:
[MCP tool: get_provider_fingerprint(provider="anthropic", window_hours=24)]

Why openclaw-upgrade-orchestrator-mcp

Three things existing tools (vendor changelogs, internal runbooks, generic CI/CD orchestrators) don't do:

1. 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.

2. 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?"

3. 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.

Backends

Backend	Status	Description
mock	✅ v1.0	2026.4.23 deployment with active R-73421 Discord-receive breakage; in-memory snapshots; suitable for protocol verification + bundle demos. v1.2: also pre-populates a synthetic 7d-baseline + last-hour-regression-burst on Anthropic so detect_provider_regression returns CRITICAL out of the box
openclaw-system	✅ v1.0	Reads ~/.openclaw/version + ~/.openclaw/gateway.yaml; persists snapshots as JSON in ~/.openclaw/upgrades/snapshots/. 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. Override via OPENCLAW_PROVIDER_CALLS_FILE

Regression catalog (v1.0)

8 hand-curated entries covering documented OpenClaw regressions:

• R-41372-CRON-WEB-SEARCH-SILENT-FAIL (HIGH, 2026.4.20–2026.5.1)

Risk-aware recommendation logic

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:

• The target version is in the regression's range (post-upgrade deployment will be affected), OR
• The current version is in the regression's range (current deployment is already affected — the operator should know whether the upgrade fixes it)

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.

Roadmap

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	⏳
