At a glance: 15+ chaos engineering MCP servers across CNCF platforms, commercial tools, and cloud-native services. LitmusChaos has the strongest official MCP with 17 tools covering the full experiment lifecycle. Chaos Mesh offers the deepest fault injection (33 tools, 7 chaos types). Rating: 3.5/5.
CNCF Platforms
LitmusChaos — Official, 12 stars, 17 tools
The most complete chaos engineering MCP server. Official server for LitmusChaos 3.x (main repo: 8,700+ stars, CNCF-incubating). Covers the full lifecycle:
- Experiment management (4 tools) — list, get, run, stop experiments
- Execution monitoring (2 tools) — track runs with resiliency scoring
- Infrastructure management (3 tools) — monitor heartbeat, register infrastructure
- Environment organization (2 tools) — PROD/NON_PROD environments
- Resilience probes (2 tools) — HTTP, Command, K8s, Prometheus probes
- ChaosHub integration (2 tools) — browse faults and documentation
- Analytics (2 tools) — statistics and resiliency score distributions
Chaos Mesh MCP — 33 tools, 7 chaos types
Community server (1 star, Python, MIT) with the deepest fault injection coverage:
- NetworkChaos — delay, packet loss, partition, corruption
- StressChaos — CPU, memory, combined stress
- PodChaos — pod kill, pod failure, container kill
- IOChaos — latency, fault injection, attribute override, data corruption
- HTTPChaos — abort, delay, replace, patch
- DNSChaos — error injection, random IP responses
- PhysicalMachineChaos — CPU/memory stress, disk fill, process kill, clock skew
Most comprehensive fault injection MCP available, but minimal adoption (1 star).
Commercial Platforms
Gremlin — Official, 5 stars, 11 tools
Read-only by design — safely query reliability data without affecting systems. List services, get dependencies, generate reliability and pricing reports, view attack summaries. RBAC scoping via API keys. The read-only choice is deliberate: Gremlin runs real fault injection, so AI-triggered experiments without human review would be risky.
Steadybit — Official, 0 stars, 11 tools
Browse experiment designs, view execution history, discover actions, list schedules and templates. Smart safety: only write operation is creating experiments from pre-approved templates — the AI can't create arbitrary fault configurations. 60 commits, Docker deployment.
Harness — 30 stars, 6 chaos tools
Part of Harness's unified MCP server (21+ toolsets). List/describe/run experiments, get results with resilience scores, discover monitoring probes. Best for teams already using Harness platform.
Cloud-Native
AWS FIS MCP — 3 stars, 10 tools
Community server for AWS Fault Injection Service. 6 read-only tools (always on) + 4 write tools (require --allow-writes flag). List/inspect templates, start/stop experiments, create templates. Read-only default is the right safety choice for a fault injection service.
What's Missing
- No ChaosBlade MCP (Alibaba, 6,000+ stars)
- No Toxiproxy MCP (Shopify, most widely adopted)
- No Netflix Chaos Monkey MCP
- No Chaos Toolkit MCP
- No Azure Chaos Studio or GCP equivalent
- Limited safety controls — most lack approval workflows, blast radius limits, automatic rollback
- No cross-platform abstraction
Rating: 3.5/5 — Solid foundation with LitmusChaos leading on completeness and Chaos Mesh on depth. Commercial platforms wisely default to read-only. The biggest gap is safety-controlled direct fault injection — AI-guided chaos with human approval gates doesn't exist yet.
