Agentry is an agent-first error monitoring and product analytics platform. Instead of a SaaS dashboard, you install an MCP server in your AI coding agent (Claude Code, Cursor, Codex, etc.) — the agent investigates errors, queries analytics, attributes deploys, and writes fixes. No SDK to install; the agent is the SDK.

How is Agentry different from Sentry?

Sentry is built around a human-facing dashboard that engineers open to triage errors. Agentry is built around an AI coding agent that triages and fixes errors directly in your editor. Both capture errors; Agentry adds analytics and deploys, has no SDK, and lets the agent do the investigation work that humans normally do in a dashboard.

How is Agentry different from PostHog or Mixpanel?

PostHog and Mixpanel are product-analytics tools built for human analysts to explore data via UI. Agentry exposes the same HogQL query layer to your AI agent — you ask questions in plain English in your editor, the agent writes the SQL, returns the result, and optionally publishes a public dashboard. Errors and deploys are first-class signals alongside analytics, all in one product.

Does Agentry require installing an SDK in my app?

No. Agentry has no SDK by design. Your AI agent generates a ~25-line fetch helper at install time that POSTs errors, analytics events, and deploys to three HTTP endpoints. You can use plain curl from CI, fetch from your app, or any language with an HTTP client. Total install footprint is well under 50 lines of your own code.

Which AI coding agents does Agentry work with?

Any agent that supports the Model Context Protocol (MCP): Claude Code, Cursor, Codex, Cline, Windsurf, and others. Install once with `claude mcp add Agentry -- npx -y @agentrysh/mcp` (or the equivalent for your client). The MCP server runs locally; it never sends your code to Agentry's servers.

What does Agentry cost?

Free during the current beta. Plans (free / pro / scale) are wired in the schema but not metered yet. Aim to stay free for indie/hobbyist use forever; usage-based pricing for teams when limits are introduced.

How do I install Agentry?

Tell your AI agent: 'Install https://agentry.sh/agentry.md and set it up'. The agent fetches the canonical reference, starts a device-flow login (you sign in at agentry.sh/cli with GitHub, Google, or magic-link email), mints an API key, creates a project, generates the fetch helper for your stack, instruments errors + analytics + deploys, and runs verify-install — all in one pass.

Predict churn 30 days before it happens

> Find behaviors that predict churn. Compare users who churned last month vs users who renewed. Build a saved cohort of at-risk users I can email.▎

Got it — I'll build two cohorts (April churners + renewers), diff their pre-decision behavior, save a live at_risk_users cohort, then write a local /admin/churn-risk page with the chart + a draft save email.

⏺ agentry_create_cohort (churned_april)

★ insight

Collaboration goes to zero first — content events follow. Churn is predictable 30 days out from behavior, not from billing signals.

Why this exists

The interface changed.

Modern observability tools were designed for humans clicking dashboards. AI agents change the interface.

Agents can:

▸ build customized views
▸ automate operational workflows
▸ generate integrations
▸ analyze trends and suggest improvements
▸ investigate incidents and fix bugs

Agentry is designed from the ground up for agentic software development.

Features

What's in the box.

Built for AI agents as the primary user, not humans clicking dashboards.

ONE EVENT STORE

Logs, errors, analytics, and deploys land in the same project. One key, one dataset, one query surface.

NO SERVER-SIDE MAGIC

Agentry stores; the MCP transforms. Every transformation lives in your node_modules — reviewable in 30 seconds, reproducible offline.

CASES & SUPPRESSION

Duplicate errors collapse into one case by fingerprint. Your agent records suppression rules — noise teaches itself out.

DEPLOY-AWARE DEBUGGING

Automatically correlate regressions with releases and commits. One tool call answers "what shipped before this broke?".

AGENT-GENERATED OPS

Queries become conversations. Dashboards become customized artifacts. Ask, your agent runs the SQL and writes the page.

WEBHOOKS & AUTOMATIONS

Signed webhooks on any event. Cron jobs your agent writes. Automate fixes, reports, and alerts — your code runs, not ours.

FAQ

Questions you might have.

Compatible with Sentry?

Yes — drop-in. Point your existing Sentry SDK at Agentry's /v1/store/{project_id}/. The wire format is Sentry's literal event schema (event_id, exception.values, stacktrace.frames). Auth accepts X-Sentry-Auth and sentry_key.

Compatible with PostHog?

Yes — and PostHog is the analytics backend under the hood. Each Agentry user gets a provisioned PostHog project. PostHog-shaped clients drop in at /v1/track/. Your analytics keep working; you just get an agent-first interface on top.

Do I need to use Claude Code?

No. Agentry speaks MCP, so it works with any MCP client — Cursor, Windsurf, Cline, Codex, or your own. We optimize for Claude Code because that's what we use, but nothing's tied to it.

Do I even need to install the MCP?

No. Point any agent at https://agentry.sh/agentry.md — it's the canonical reference. The agent reads it, understands the full API surface (storage + retrieval + queries), and can drive everything via plain HTTP. The MCP is the accelerator: stateful auth, structured tool calls, local stack unmangling. Both paths reach the same outcome.

What languages does this support?

Anything that can POST JSON. There is no SDK to install — your agent generates a 25-line fetch helper at install time, tuned to your stack. Reviewable in 30 seconds, no vendor dependency to vet, no upgrade cycle.

Does the server transform my data?

No. Agentry's HTTP API is the data plane — storage, retrieval, queries. Transformations (stack unmangling, fingerprinting, formatting) run locally in your MCP, where the code sits in your node_modules. If a translation looks wrong, read it and reproduce it offline. No server-side magic.

What about humans who want a dashboard?

Your agent writes the dashboard as a real page in your repo. You can commit it, edit it, and ship it. No SaaS UI to learn — and no permanent dashboard config rotting over time.

Do you train AI on my data?

No. We never run LLMs server-side. The agent that reads your data is your Claude Code (or other MCP client) running on your machine. Your data stays in your Agentry project.

Agentry isn't trying to replace Sentry's source-map polish or PostHog's cohort-analysis depth. We sit on top of both worlds with a single ingest, an MCP-shaped output, and a workflow that ends in a PR instead of a notification.
