Openclaw Upgrade Orchestrator MCP Server

openclaw-upgrade-orchestrator-mcp

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?" 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.

> claude: has Anthropic regressed something on their end in the last hour?

Severity: CRITICAL
provider: anthropic
current_window_hours: 1   sample_count: 50

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.

Quickstart

Install

pip install openclaw-upgrade-orchestrator-mcp

Quick verify (~30 seconds, no config)

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.

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.
