Turns CI failures into structured release verdicts by correlating error signatures, flakiness history, and code changes. Exposes six tools: aggregate_suite_failures groups errors by normalized signature, cross_reference_flakiness scores against historical data, correlate_code_changes maps failures to changed files, generate_release_recommendation outputs GO/CONDITIONAL_GO/NO_GO/INVESTIGATE with risk scores and domain severity (payment, auth, billing get blocked), detect_temporal_failure_patterns finds time-based artifacts like DST or hourly flakes, and analyze_rollback_readiness scans migration files for destructive operations. Outputs markdown ready for PR comments. Works standalone or composes with flakiness-knowledge-graph-mcp and ast-impact-mapper-mcp. Reach for this when you need an AI agent to triage broken CI runs without reading thousands of lines of logs.
Stop reading CI logs. Start getting verdicts.
MCP server that aggregates test failures, cross-references flakiness history, and outputs a GO / CONDITIONAL_GO / NO_GO / INVESTIGATE release decision — so your AI agent can triage a broken CI run in seconds instead of asking you to read 3000 lines of logs.
In any real codebase, CI always has something failing. The hard question isn't "are there failures?" — it's "are these failures real regressions, or just the usual noise?"
Answering that requires correlating three signals at once:
An AI agent can't do this without structured tools. Raw CI logs are thousands of lines. Flakiness databases are external. Code→test mapping requires AST analysis. Without this MCP, the agent just guesses.
aggregate_suite_failuresGroups failures by normalized error signature, deduplicates repeated errors, categorizes as assertion / timeout / network / crash. Pass customInfraPatterns for cloud-specific errors.
cross_reference_flakinessScores each failure against your flakiness history: KNOWN FLAKY, MILDLY FLAKY, or NO HISTORY.
correlate_code_changesMatches changed files against failing tests. Works standalone or with pre-computed affected test lists from ast-impact-mapper-mcp.
generate_release_recommendationThe final step. Outputs a risk-weighted verdict with confidence score and full breakdown. Supports format: "markdown" for GitHub PR comments and Slack.
Verdict levels:
NO_GO — regression in a critical domain (payment, auth, billing, checkout, security)CONDITIONAL_GO — regression in a low/medium-risk domain (analytics, docs, admin); review before releasingGO — all failures are known flaky or infrastructure noiseINVESTIGATE — too many unknowns to decideOutput includes:
aggregate_risk_score — 0.0–1.0, probability union across all regression risk contributionsfailing_tests_analysis[] — per-regression breakdown with domain, severity (HIGH/MEDIUM/LOW), risk_contribution, blast_radiusdetect_temporal_failure_patternsAnalyzes historical failures with timestamps to identify chronometric artifacts — failures that only appear at the same UTC hour, weekday, day of month, or during DST transitions. When a pattern is found, the failure is a time artifact, not a code regression.
Output includes:
temporal_pattern_detected — booleanclusters[] — per-test: pattern_type (hourly | daily | monthly | timezone_shift), cluster_times, confidence_scoreanalyze_rollback_readinessScans a repository for versioned migration files (Flyway V*.sql, Prisma migration.sql, Liquibase XML/YAML) and classifies each operation as additive (rollback safe) or destructive (forward-fix only).
Detected destructive operations: DROP TABLE, DROP COLUMN, ALTER COLUMN TYPE, MODIFY COLUMN, TRUNCATE
Output includes:
rollback_eligible — booleanblocking_migrations[] — each with file, line, operation, reasondeployment_strategy — standard | forward_fix_only5 failures in CI. What's real, what's noise?
failures:
- Auth Suite > login with expired token → "Expected status 200, got 401"
- API Suite > health check → "connect ECONNREFUSED 127.0.0.1:3000"
- Button Suite > renders button correctly → "Expected null, got <button>Submit</button>"
- Search Suite > debounce timing → "Expected 42, received 43"
- Storage Suite > upload avatar → "GCP quota exceeded for this project"

### Blockers (must fix before release)
**Button Suite > renders button correctly**
- Test is directly affected by code changes in this commit
- `Expected null, got <button>Submit</button>`
### Safe to ignore
- ~~Auth Suite > login with expired token~~ — Historically flaky: 73% failure rate in history
- ~~API Suite > health check~~ — Error pattern matches infrastructure issues (network)
- ~~Search Suite > debounce timing~~ — Mildly flaky: 22% historical failure rate
- ~~Storage Suite > upload avatar~~ — Error pattern matches infrastructure issues (network)
One tool call. One verdict. Go fix Button.tsx.

The agent calls generate_release_recommendation and returns a verdict with a full breakdown — ready to paste into a PR comment or Slack.
