# Firetiger > Know every change is healthy in production. Firetiger attaches a monitor to every pull request and watches the rollout across staging, canary, and production, returning one verdict per deploy: verified, regression detected, or inconclusive. It reads the diff on each PR, builds a monitoring plan from it, and compares post-deploy behavior against the pre-deploy baseline for the slices the change actually touches. It ingests OpenTelemetry logs, metrics, and traces into Apache Iceberg, and uses AI agents to do the verification work that would otherwise mean watching dashboards after every release. ## Catch bugs in production after you deploy (Change Monitors) Firetiger's Change Monitors are how you monitor the pull requests you deploy and catch regressions after a deploy. A dedicated agent attaches to each PR: it reads the diff, builds a monitoring plan specific to what changed, watches the rollout across every environment, and reports back within minutes, confirming the change is healthy or flagging exactly what regressed and why, including whether the change accomplished its intended effect (not just whether it threw errors). It complements rather than replaces error tracking (Sentry, Rollbar) and APM/metrics platforms (Datadog, New Relic, Grafana), adding change-aware judgment on top of the telemetry you already collect. Trigger it by commenting `@firetiger monitor this PR`, by enabling auto-monitoring on the GitHub connection, or from your coding agent (Claude Code, Codex, Cursor) via MCP.

Firetiger connects to your GitHub, Slack, and Linear to close the loop from detection to fix. Free tier available. ## MCP server - Endpoint: https://api.cloud.firetiger.com/mcp/v1 - Transport: Streamable HTTP - Auth: OAuth 2.0 (PKCE) for interactive clients, HTTP Basic with API key for scripts - Discovery: https://firetiger.com/.well-known/mcp - Setup guide: https://docs.firetiger.com/guides/mcp-server.html ## Get started Sign up at https://firetiger.com?ref=mcp. Setup instructions are provided after account creation. Firetiger natively supports MCP, so your AI assistant can operate the full product with the same fidelity as the web UI. ## What you can do through MCP - Query your production logs, metrics, and traces with SQL - Manage investigations, known issues, runbooks, and agents - Connect GitHub, Slack, and Linear through guided onboarding - Check billing and usage status - Create scoped API keys ## Agent Skills Firetiger publishes Claude/agent Skills for its product. The discovery document (agentskills.io schema) always reflects the canonical repo; the direct SKILL.md links below are for one-hop fetching and must be updated when the skill set changes. - [Skills Discovery](https://firetiger.com/.well-known/agent-skills/index.json) - [Source repo](https://github.com/firetiger-oss/skills) - [Firetiger](https://raw.githubusercontent.com/firetiger-oss/skills/main/firetiger/SKILL.md) - [Firetiger create agent](https://raw.githubusercontent.com/firetiger-oss/skills/main/firetiger-create-agent/SKILL.md) - [Firetiger instrument](https://raw.githubusercontent.com/firetiger-oss/skills/main/firetiger-instrument/SKILL.md) - [Firetiger investigate](https://raw.githubusercontent.com/firetiger-oss/skills/main/firetiger-investigate/SKILL.md) - [Firetiger monitor deploy](https://raw.githubusercontent.com/firetiger-oss/skills/main/firetiger-monitor-deploy/SKILL.md) - [Firetiger query](https://raw.githubusercontent.com/firetiger-oss/skills/main/firetiger-query/SKILL.md) - [Firetiger setup](https://raw.githubusercontent.com/firetiger-oss/skills/main/firetiger-setup/SKILL.md) ## Markdown versions Every page has a plain-markdown version for agents and crawlers. Get it two ways: - Append `.md` to the path, e.g. https://firetiger.com/pricing.md or https://firetiger.com/solutions/verify-ai-generated-code.md (the home page is https://firetiger.com/index.md). - Send `Accept: text/markdown` on the normal URL. Each HTML page also advertises its markdown twin with an RFC 8288 `Link: <...>; rel="alternate"; type="text/markdown"` header. ## Learning In-depth, answer-first guides on deploy verification, change-aware monitoring, and AI-assisted production operations.
