Plugins

Plugins add provider manifests, credentials, tools, runtime hooks, background work, and optional skills. Start with a packaged plugin when one exists; build a custom plugin only when the app needs a new provider or deterministic runtime behavior.

Choose a plugin

Plugin	Use it for
Agent Browser	Browser automation
Amplitude	Product analytics queries
Cloudflare	Cloudflare resources and APIs
Datadog	Logs, metrics, and incidents
GitHub	Repository, issue, and pull-request workflows
Hex	Hex projects and runs
Linear	Issues and projects
Maintenance	Repository maintenance workflows
Memory	Long-term scoped memory
Notion	Notion content
Scheduler	Durable scheduled tasks
Sentry	Sentry issues and telemetry
Vercel	Vercel projects and deployments

Install packaged plugins

Install only the packages the app needs:

pnpm add @sentry/junior @sentry/junior-github @sentry/junior-sentry

Create one plugin set for local development and production builds:

plugins.ts

import { defineJuniorPlugins } from "@sentry/junior";
import { githubPlugin } from "@sentry/junior-github";

export const plugins = defineJuniorPlugins([
  githubPlugin({
    botNameEnv: "GITHUB_APP_BOT_NAME",
    botEmailEnv: "GITHUB_APP_BOT_EMAIL",
  }),
  "@sentry/junior-sentry",
]);

Point Nitro at the plugin module:

nitro.config.ts

import { defineConfig } from "nitro";
import { juniorNitro } from "@sentry/junior/nitro";

export default defineConfig({
  preset: "vercel",
  modules: [juniorNitro({ plugins: "./plugins" })],
  routes: {
    "/**": { handler: "./server.ts" },
  },
});

Pass the same set to the app:

server.ts

import { createApp } from "@sentry/junior";
import { plugins } from "./plugins.ts";

export default await createApp({ plugins });

Manifest-only plugins may be registered by package name. Plugins with runtime hooks export a JavaScript factory. Each provider page documents its required registration and environment variables.

Add an app-local plugin

App-local declarative plugins live under the app content root:

app/plugins/<plugin-name>/
├── plugin.yaml
└── skills/
    └── <skill-name>/
        └── SKILL.md

Use this shape for app-specific provider configuration or workflows that do not need backend hooks. Runtime hooks and host tools require a code plugin; follow Build a Plugin.

Validate

Run validation before deploy:

pnpm exec junior check

If a plugin declares sandbox dependencies, also build its dependency snapshot:

pnpm exec junior snapshot create

Next step

Open the provider page for credential setup, or follow Build a Plugin for a custom integration.
