Install

Skills CLI

npx skills add monte-carlo-data/mc-agent-toolkit

Asks which skills and agents to install. Just one: npx skills add monte-carlo-data/mc-agent-toolkit --skill monte-carlo-analyze-root-cause — add -g for every project.

Claude Code

git clone https://github.com/monte-carlo-data/mc-agent-toolkitcp -r "mc-agent-toolkit/skills/analyze-root-cause" ~/.claude/skills/

Copies the monte-carlo-analyze-root-cause skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add monte-carlo-data/mc-agent-toolkit

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • monte-carlo-analyze-root-cause

    Investigate data incidents and find root causes using Monte Carlo's observability data. Guides the agent through systematic investigation: alert lookup, lineage tracing, ETL checks, query analysis, and data profiling. Activates when a user asks about data issues, incidents, alerts, or why data looks wrong.

    skills/analyze-root-cause/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-asset-health

    Check the health of a data table/asset using Monte Carlo. Activates on "how is table X", "check health of X", "is X healthy", "status of X", "check on X table", or any health/status question about a data asset.

    skills/asset-health/SKILL.md on GitHub (opens in a new tab)
  • automated-triage

    Triage Monte Carlo alerts interactively or build an automated workflow. Fetch, score, and troubleshoot alerts using MCP tools now, or design a reusable workflow that runs on a schedule.

    skills/automated-triage/SKILL.md on GitHub (opens in a new tab)
  • connection-auth-rules

    Build a Connection Auth Rules for a Monte Carlo connection type. Fetches live connector schemas and transform steps from the apollo-agent repo.

    skills/connection-auth-rules/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-context-detection

    Route data-related requests to the right Monte Carlo skill or workflow. USE WHEN alerts, incidents, data broken, stale, coverage gaps, data quality, or any ambiguous data observability request.

    skills/context-detection/SKILL.md on GitHub (opens in a new tab)
  • generate-validation-notebook

    Generate SQL validation notebooks for dbt changes. Pass a GitHub PR URL or local dbt repo path.

    skills/generate-validation-notebook/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-incident-response

    Orchestrate incident response — triage, root cause, remediate, prevent recurrence. USE WHEN active alerts, data broken, stale, pipeline failure, or investigate and fix a data incident.

    skills/incident-response/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-instrument-agent

    Instrument a new AI agent in a Python codebase for Monte Carlo Agent Observability. Detects AI libraries, installs the Monte Carlo OpenTelemetry SDK, and proposes tracing setup and decorator placements as diffs. Asks before editing any file.

    skills/instrument-agent/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-manage-mac

    Create, edit, validate, and import Monitors-as-Code YAML files. CLI-first; falls back to MC MCP tools, then manual validation.

    skills/manage-mac/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-monitoring-advisor

    Analyze data coverage, create monitors for warehouse tables and AI agents. Covers coverage gaps, use-case analysis, data monitor creation, and agent observability.

    skills/monitoring-advisor/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-onboarding

    Connect a warehouse to Monte Carlo using API v2 tools. Discover or provision deployments, reference credentials, reuse or create the connection, and validate it. Use when asked to connect a platform or onboard a warehouse, including generating the Terraform or a script for it.

    skills/onboarding/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-performance-diagnosis

    Diagnoses pipeline performance issues -- slow jobs, expensive queries, latency trends -- using Monte Carlo's cross-platform observability. Uses a tiered investigation approach: discover problems, bridge to affected tables, then drill into root causes. Activates when a user asks about slow pipelines, expensive queries, or performance regressions.

    skills/performance-diagnosis/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-prevent

    Shift-left safety net for dbt/SQL model edits. Runs change impact assessment before edits, generates SQL validation queries after, and executes them via `/mc-validate run`. Delegates health and monitor creation to peer skills.

    skills/prevent/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-proactive-monitoring

    Guide users from coverage analysis to monitor creation. USE WHEN user asks what should I monitor, where are my gaps, improve coverage, or wants a systematic approach to monitoring across their data estate.

    skills/proactive-monitoring/SKILL.md on GitHub (opens in a new tab)
  • push-ingestion

    Expert guide for Monte Carlo's push ingestion model. Use this skill whenever a customer or engineer mentions: pushing data to Monte Carlo, the IngestionService, pycarlo push APIs, build me a collection script, push metadata/lineage/query logs, invocation_id tracing, custom lineage nodes or edges, deleting push tables, or any question about why pushed data is not showing up. Also trigger when they…

  • monte-carlo-reinforce-agent

    Reinforces an AI agent by turning Monte Carlo's reinforcement loop diagnosis into code fixes. Reads the daily reinforcement loop report for an agent's workflows, ranks the diagnosed issues, proposes what to fix, and — with the user's approval at each step — opens a pull request. Activates on "fix my agent", "improve my agent's health", "reinforce my agent", "what should I fix in my agent". Not fo…

  • monte-carlo-remediation

    Investigate and remediate data quality alerts using Monte Carlo MCP tools. Runs root cause analysis, assesses blast radius, discovers available tools (MCP/CLI/API), proposes and executes fixes, or escalates with full context when uncertain.

    skills/remediation/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-storage-cost-analysis

    Analyze a warehouse for stale, unused, or redundant tables via the analyze_storage_costs MCP tool. Classifies waste patterns and table categories, computes safety tiers, and handles category drill-downs and lineage follow-ups.

    skills/storage-cost-analysis/SKILL.md on GitHub (opens in a new tab)
  • monte-carlo-troubleshoot-agent-traces

    Troubleshoots Monte Carlo AI agent alerts and traces — eval score drops, latency/token spikes, trajectory and validation breaches. Not for data incidents (monte-carlo-analyze-root-cause) or monitor creation (monte-carlo-monitoring-advisor).

    skills/troubleshoot-agent-traces/SKILL.md on GitHub (opens in a new tab)
  • tune-monitor

    Analyze a Monte Carlo monitor and recommend config changes to reduce alert noise. Supports metric, custom SQL, validation, table, and agent (metric, evaluation, trajectory, validation) monitors. Fetches the report, identifies patterns, and suggests tuning.

    skills/tune-monitor/SKILL.md on GitHub (opens in a new tab)
  • toolkit-skill-author

    Authors or extends a skill in mc-agent-toolkit. Gates for forbidden buckets and name collisions, applies CONTRIBUTING's extend-or-split rules, then edits a peer skill or hands off to Anthropic's skill-creator and walks the registration checklist.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
