mcp-circuit-breaker SKILL.md skillA
mcp-circuit-breaker from chrono-meta/forge-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add chrono-meta/forge-harness/mcp-circuit-breaker@git:20260811.eede7adPins git:20260811.eede7ad in mdr.lock. Pin the fingerprint instead.

Detects MCP tool failure patterns and trips a circuit breaker to stop cascading retries. Proposes fallback alternatives and resets when the tool recovers. Triggers on "MCP failing", "tool keeps erroring", "circuit-breaker", repeated tool call failures.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# mcp-circuit-breaker — MCP Tool Failure Guard MCP tools can fail silently or return partial results, leading to cascading retry loops that waste tokens and degrade session quality. This skill detects failure patterns, trips a circuit breaker to halt retries, proposes alternatives, and resets when the tool recovers. > **Scope distinction** > - Claude Code native retry: low-level transport retries (transparent, fast) > - mcp-circuit-breaker: **session-level guard** — detects repeated semantic failures, intervenes before token waste compounds --- ## Triggers - `/mcp-circuit-breaker` - "MCP failing", "MCP keeps erroring", "tool isn't working", "circuit-breaker" - "same error keeps happening", "tool call looping", "MCP timeout" - Automatic: when the same MCP tool name appears in 3+ consecutive failed calls within a session --- ## Circuit States ``` CLOSED → Normal operation (tool calls pass through) OPEN → Circuit tripped (calls blocked, alternatives proposed) HALF-OPEN → Recovery probe (1 test call allowed, resets if success) ``` Default thresholds: - **Trip threshold**: 3 consecutive failures of the same tool …

How to install
mdr add chrono-meta/forge-harness/mcp-circuit-breaker@sha256:ec38ca2930ea4349The line at the top of this page pins the label git:20260811.eede7ad, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
