This skill detects failure patterns, trips a circuit breaker to halt retries, proposes alternatives, and resets when the tool recovers.\n\n> **Scope distinction**\n> - Claude Code native retry: low-level transport retries (transparent, fast)\n> - mcp-circuit-breaker: **session-level guard** — detects repeated semantic failures, intervenes before token waste compounds\n\n---\n\n## Triggers\n\n- `/mcp-circuit-breaker`\n- \"MCP failing\", \"MCP keeps erroring\", \"tool isn't working\", \"circuit-breaker\"\n- \"same error keeps happening\", \"tool call looping\", \"MCP timeout\"\n- Automatic: when the same MCP tool name appears in 3+ consecutive failed calls within a session\n\n---\n\n## Circuit States\n\n```\nCLOSED   → Normal operation (tool calls pass through)\nOPEN     → Circuit tripped (calls blocked, alternatives proposed)\nHALF-OPEN → Recovery probe (1 test call allowed, resets if success)\n```\n\nDefault thresholds:\n- **Trip threshold**: 3 consecutive failures of the same tool\n- **Half-open probe**: after 60s cooldown (or explicit user command)\n- **Reset**: 1 successful call in HALF-OPEN state → back to CLOSED\n\n---\n\n## Execution Steps\n\n### Step 1. Detect Failure Pattern\n\nIdentify the failing tool and failure mode:\n\n```bash\n# MCP mounts live in SEVERAL scopes — check all that this shell can see. Project settings.json is\n# usually NOT one of them (it commonly holds hooks only), so a single-file read renders \"no config\"\n# on a session with live MCP servers — a wrong-location instrument, not a measurement.\nfor f in .mcp.json .claude/settings.json .claude/settings.local.json; do\n  [ -e \"$f\" ] && { echo \"== $f ==\"; grep -A5 '\"mcpServers\"' \"$f\" 2>/dev/null || echo \"(present, no mcpServers key)\"; }\ndone\n[ -e ~/.claude.json ] && grep -c '\"mcpServers\"' ~/.claude.json | xargs echo \"user-scope ~/.claude.json mcpServers blocks:\"\n```\n\nAn empty result above means **\"no project/user-scope config found\"** — never \"no MCP mounted\":\nplugin-provided and remotely-managed servers appear in no local file. The live mount evidence is the\nfailing tool call itself (`mcp__{server}__{tool}` in this session); classify from that name even when\nevery config read comes back empty.\n\nClassify failure type:\n\n| Type | Symptom | Likely Cause |\n|---|---|---|\n| `TIMEOUT` | Tool call hangs >30s | Server overload / network |\n| `AUTH` | 401 / 403 response | Credentials expired or missing |\n| `NOT_FOUND` | 404 / tool not available | Server down / tool removed |\n| `MALFORMED` | Parse error on response | Schema mismatch / API change |\n| `RATE_LIMIT` | 429 / quota exceeded | Too many calls |\n| `ADMIN_GATED` | \"instance admin approval required\" / server pending org enablement / tool unavailable until approved | Capability exists; the **MCP mount** is gated behind instance/admin permission — not a transport failure. Retrying never recovers it (an admin must act) |\n\nIf failure type cannot be determined: classify as `UNKNOWN`.\n\n> **`ADMIN_GATED` is not a retry case.** Distinguish *capability unavailable* from *MCP transport\n> unavailable*: when the block is an org/admin approval dependency, do not burn retries — route straight\n> to the lower-permission substitute in Step 4 (Priority 1b).\n\n---\n\n### Step 2. Trip Decision\n\nCount consecutive failures of the identified tool in the current session context.\n\n| Count | Action |\n|---|---|\n| 1 | Log warning. Continue — *\"MCP tool {name} failed once. Monitoring.\"* |\n| 2 | Escalate warning. Suggest checking server status. |\n| 3+ | **TRIP CIRCUIT** → output circuit open notice, block further calls to this tool |\n\n> **Non-transient types trip at count 1, not 3.** `ADMIN_GATED`, `AUTH`, and `NOT_FOUND` do not recover\n> on retry (an admin must act / credentials must change / the tool is gone), so counting to 3 only wastes\n> calls. On the first failure of one of these types, trip immediately and go to Step 4. The 1→2→3 ramp is\n> for *transient* types (`TIMEOUT`, `RATE_LIMIT`) where a later call may succeed.\n\nCircuit open notice format:\n```\n⚡ CIRCUIT OPEN — {tool-name}\nFailure type: {TYPE}  |  Consecutive failures: {N}\nFurther calls to this tool are blocked until circuit resets.\n```\n\n(Blocking is **session-level discipline** — this skill's protocol, not a mechanical hook; no\nPreToolUse gate enforces it. State it that way if asked — a protocol honestly labeled beats a\nphantom enforcement claim.)\n\n---\n\n### Step 3. Log Circuit State\n\nWrite state to session-local file (in-memory is insufficient — logs survive /clear):\n\n```bash\nmkdir -p .claude/mcp_circuit/\ngrep -qxF '.claude/mcp_circuit/' .gitignore 2>/dev/null \\\n  || echo \"NOTE: add '.claude/mcp_circuit/' to .gitignore — session state must not become a tracked file (the ignored-but-committed class public-surface-audit Step 3c hunts)\"\ncat >> .claude/mcp_circuit/circuit_log.yaml << EOF\n- tool: {tool-name}\n  state: OPEN            # OPEN | HALF-OPEN | CLOSED — same enum as Done When\n  failure_type: {TYPE}\n  failure_count: {N}\n  tripped_at: {ISO-8601}\n  reset_at: null\nEOF\n```\n\n---\n\n### Step 4. Propose Alternatives\n\nPresent the relevant fallback options ranked by effort (at least 3):\n\n| Priority | Alternative | When to Use |\n|---|---|---|\n| **1 — Substitute tool** | Use a different MCP tool or built-in tool that covers the same task | Tool-specific failure (NOT_FOUND, AUTH) |\n| **1b — Lower-permission API / workflow substitute** | The MCP mount is gated, but the underlying capability is usually still reachable through a member-scoped path: a Personal-Access-Token REST API call, or a workflow-automation runner. Before relying on it, confirm **credential scope** (a member-level token suffices?), **audit parity** (logged where the MCP path would log?), and **behavior gap** (what the MCP path does that this does not — e.g. natural-language workflow creation vs hand-written JSON). | `ADMIN_GATED` |\n| **2 — Degrade gracefully** | Skip the MCP step, note the gap, continue with available information | TIMEOUT / RATE_LIMIT |\n| **3 — Pause and retry** | Wait for server recovery (HALF-OPEN probe after cooldown) | Transient failure (TIMEOUT, RATE_LIMIT) |\n\n> **Gating carries over to the substitute** (cross-ref the external-MCP tool-gating rule\n> `templates/.claude/rules/mcp_tool_gating.md` — template path; if installed live, your repo's\n> `.claude/rules/` copy). A REST/API or\n> workflow-automation tool adopted under Priority 1b is still an external-action surface: classify its\n> calls under the same ask/allow tiers — reads are `allow (untrusted-read)` only after behavior\n> confirmation; any write / send / delete / permission-change stays `ask`. Trading a gated MCP mount for\n> an ungated REST token does not lower the action's risk — only its permission barrier.\n\nOutput format:\n```\n## Fallback Options for {tool-name}\n\nOption 1 — Substitute: Use {alternative-tool} instead\n  → Command: [specific invocation]\n  → Gap: [what's different vs. original tool]\n\nOption 2 — Degrade: Skip this step, continue without {capability}\n  → Impact: [what is missing from the output]\n\nOption 3 — Retry after cooldown (60s)\n  → Run: /mcp-circuit-breaker reset {tool-name}\n```\n\n---\n\n### Step 5. Recovery Probe (HALF-OPEN)\n\nWhen user requests reset or after cooldown:\n\n```\nSending HALF-OPEN probe to {tool-name}...\n```\n\n- 1 minimal test call is allowed through\n- If success: circuit → CLOSED, log updated\n- If fail: circuit remains OPEN, cooldown resets\n\nReset log entry — **append as a NEW list item (`- tool:`), never as bare indented keys**:\n```yaml\n- tool: {tool-name}\n  state: CLOSED\n  reset_at: {ISO-8601}\n  reset_method: probe_success | user_forced\n```\n\n> **Why the leading `- tool:` is load-bearing.** The Step 3 log is a YAML *list*. Appending indented\n> keys with no `-` merges them into the **previous** item instead of adding one, and PyYAML resolves\n> duplicate keys silently by keeping the last value — so `state: OPEN` is overwritten by `CLOSED` and\n> the trip record disappears. Measured 2026-08-11: trip entry + bare-key reset entry parses to\n> **1 item** with `state: CLOSED` (the OPEN row is gone); the same pair written as two list items\n> parses to **2 items** with the trip history intact. The state history is what Step 6 reports on, so\n> a merged entry silently zeroes the failure record.\n\n---\n\n### Step 6. Report\n\nAt session end or on demand:\n\n```\n## MCP Circuit Breaker Report\n\n| Tool | State | Failures | Tripped | Reset |\n|---|---|---|---|---|\n| {tool} | OPEN | 4 | 14:23 | — |\n| {tool} | CLOSED | 1 | 14:10 | 14:15 (probe) |\n\nRecommendations:\n- {tool}: AUTH failure → refresh credentials in .claude/settings.json\n```\n\n---\n\n## Done When\n\n- Failure pattern classified (type + count) — *judged* (adversarial pairing: an `UNKNOWN`\n  classification must state which Step 1 config reads ran and came back empty — \"couldn't determine\"\n  without the read evidence is not a classification)\n- Circuit state logged to `.claude/mcp_circuit/circuit_log.yaml` (OPEN / HALF-OPEN / CLOSED) —\n  *mandatory-pass*\n- At least 3 fallback alternatives proposed when circuit is OPEN — *measured* (count ≥3)\n- Recovery probe offered with reset path — *mandatory-pass*\n\n---\n\n## Chains\n\n**Upstream** (can trigger this skill):\n- Automatically activates on 3+ consecutive MCP failures during any task\n\n**Downstream** (after circuit open):\n- No mandatory chain — fallback options are presented, user decides\n- Optional: `context-doctor` if MCP failure is due to large context degrading tool calls\n","tagline":"Detects MCP tool failure patterns and trips a circuit breaker to stop cascading retries.
