These extensions connect your agent to cloud platforms, deployments, infrastructure-as-code, container and cluster operations, and production observability. The central trade-off is access: read-only guidance changes nothing, while live credentials let an agent alter production systems. Grant the narrowest permission the task needs.

Azure

by Microsoft
Inspecting and operating Azure at scale
740Kestimated installs
What it isA cross-host package that combines Azure MCP, Foundry MCP, and curated Azure skills. It pairs current decision guidance with more than 200 structured tools for inspecting resources, validating deployments, diagnosing infrastructure, and optimizing costs.
When to useReach for it when building, deploying, or operating Azure and Microsoft Foundry workloads and you want the agent grounded in current practice rather than guessing. Give it least-privileged identities, and note that sovereign clouds need explicit MCP configuration.
What you needAn Azure account; the tools work through your existing subscriptions and RBAC.

Vercel logo

​
Vercel

Next.js and Vercel-stack development
300Kestimated installs
What it isA broad bundle spanning Vercel, Next.js, React, the AI SDK, deployments, performance, and infrastructure. It ships product-specific skills, specialist agents, operational commands, project-aware hooks, an ecosystem map, and, on supported routes, live Vercel account access.
When to useIts value is highest in projects built on Vercel or its ecosystem. The skills help without any login, but deployments, logs, and environment changes need Vercel authentication. In unrelated projects the broad context is mostly noise, so a narrow route serves better.
What you needA Vercel account for the live deployment and project routes; the guidance skills work without one.

Cloudflare logo

​
Cloudflare

Workers and the Cloudflare platform
250Kestimated installs
What it isA developer package that combines Cloudflare’s API MCP with skills for Workers, Durable Objects, the Agents SDK, Wrangler, MCP servers, sandboxing, and web performance. The agent gets both current platform patterns and the ability to inspect or change live Cloudflare resources.
When to useUse it when building or operating applications on Cloudflare, from Workers and storage to databases, deployments, logs, and analytics. Be deliberate about tokens: OAuth or bearer-token access can permit production writes, including deployments and security changes, so scope it to what the task requires.
What you needA Cloudflare account for live inspection and changes.

Docker MCP Toolkit logo

​
Docker MCP Toolkit

Running many MCP servers in containers
200Kestimated installs
What it isDocker’s MCP Catalog and Toolkit: a gateway that runs MCP servers as isolated containers, a curated catalog of containerized servers, and Docker Desktop integration for connecting them to agent clients with unified configuration and secrets.
When to useUse it when you already run Docker and want one controlled local layer for many MCP servers rather than configuring each separately. It is not the simplest path to a single hosted connector, and every enabled server still carries its own permissions and supply-chain risk.
What you needDocker Desktop 4.43+ or the standalone gateway. Distributed through Docker Desktop, so no public install metric exists for the toolkit itself.
InstallMCPCLI
Firebase logo

​
Firebase

by Google
Project-aware Firebase development
150Kestimated installs
What it isAn agent stack that combines Firebase skills, a local MCP server built into firebase-tools, and the Firebase CLI. It gives the agent current guidance plus project-aware access to Firestore, Authentication, Functions, Hosting, Storage, Crashlytics, Messaging, Remote Config, and security rules.
When to useUse it to build, configure, diagnose, and deploy Firebase apps with live project context instead of generic advice. Because it can change real resources, review security rules and deployments before they apply, and expose only the feature groups a task actually needs.
What you needA Google account and Firebase project; the MCP rides inside firebase-tools.

Agent Toolkit for AWS logo

​
Agent Toolkit for AWS

Auditable agent access to AWS
150Kestimated installs
What it isA managed MCP paired with a family of installable plugins: a general AWS Core plus specialist packages for agents, analytics, and DevSecOps. It gives agents current AWS guidance and auditable access to AWS APIs, documentation, and sandboxed execution.
When to useStart with AWS Core for general work and add only the specialist package a project needs rather than loading the whole collection. Live operations require AWS credentials, so use least-privileged, agent-aware IAM policies. AWS now recommends this toolkit as the successor to its Labs MCP servers.
What you needAn AWS account; access stays inside your IAM and audit controls.

Sentry logo

​
Sentry

Debugging from production errors
150Kestimated installs
What it isA hosted MCP for production issues and traces, packaged with host-specific plugins for debugging, code review, and instrumentation. It lets an agent investigate real errors, inspect events and stack traces, quantify user impact, and connect findings back to the code.
When to useUse it for error triage, production debugging, and adding Sentry instrumentation, so the agent works from real events rather than symptoms alone. Hosted access uses OAuth and can be constrained to an organization or project; the self-hosted server needs explicit token scopes.
What you needA Sentry account with the projects you debug.

Kubernetes MCP Server logo

​
Kubernetes MCP Server

by containers
Inspecting and operating clusters
100Kestimated installs
What it isA server that speaks directly to the Kubernetes API - pods, deployments, services, logs, events, and apply operations - through typed tools rather than parsed kubectl output. It ships read-only and destructive-operation controls, and is the most active and widely adopted of the community Kubernetes routes.
When to useReach for it to troubleshoot and operate clusters with the agent working from real resource state instead of shell string-parsing. Cluster credentials are high impact and write operations hit live resources, so scope the kubeconfig context and prefer a read-only mode for exploration.
What you needA Kubernetes kubeconfig or in-cluster credentials. Community-built - no Kubernetes-project-official route exists.
InstallMCP
Terraform logo

​
Terraform

Registry-grounded Terraform work
90Kestimated installs
What it isThe surface centers on HashiCorp’s MCP server, which grounds the agent in current registry, module, provider, policy, and HCP Terraform context. Alongside it, portable skills cover Terraform style, testing, refactoring, stacks, and provider development.
When to useTogether the server and skills cut stale syntax, invented provider arguments, and poorly reviewed infrastructure changes. Infrastructure credentials are high impact, so prefer read-only tokens and narrow toolsets, and keep plan and apply authority separate from plain registry or documentation lookups.
What you needNothing for registry context; HCP Terraform features need an account.
InstallPluginMCP
Netlify logo

​
Netlify

Building and deploying on Netlify
70Kestimated installs
What it isA surface that spans platform skills, MCP account tools, and the Netlify CLI. The skills carry current guidance for Functions, Edge Functions, Blobs, Netlify DB, Forms, CDN, frameworks, Identity, and AI Gateway; authorized routes can create sites, deploy code, and manage variables.
When to useUse it for projects hosted on Netlify or when building against its primitives. Knowledge-only skills need no account access, but deployments and account changes do. Review any action that modifies secrets, access controls, production deployments, or form data before it runs.
What you needA Netlify account for site and deploy actions.

Grafana logo

​
Grafana

Dashboards, metrics, and incidents
45Kestimated installs
What it isAn MCP integration for dashboards, metrics, logs, alerts, incidents, and related observability data. It comes two ways: a hosted Grafana Cloud endpoint and an open-source server you run yourself. Either gives the agent structured tools instead of scraped dashboards or hand-built API calls.
When to usePick the hosted route for the simplest Grafana Cloud setup, or the open-source server for self-managed Grafana and tighter control. Permissions flow through Grafana’s user or service-account RBAC, so use read-only mode and the smallest practical tool set on production systems.
What you needA Grafana Cloud account, or your own self-hosted server.

Datadog logo

​
Datadog

Production telemetry and monitors
40Kestimated installs
What it isOfficial routes that let an agent query production logs, metrics, traces, dashboards, monitors, incidents, and CI health. It grounds debugging in live telemetry, so the agent can correlate symptoms across services, summarize likely causes, and draft or take selected actions.
When to useReach for it during production debugging, alert tuning, service-health checks, and evidence-backed incident work. It can see sensitive production telemetry and may support writes, so confirm consequential actions. Similarly named community Datadog servers are separate products and do not share this official route’s status.
What you needA Datadog account and API access.
InstallConnectorAppPlugin
Railway logo

​
Railway

Deploying and operating on Railway
40Kestimated installs
What it isAn operational skill paired with the Railway CLI and local or hosted MCP access. It gives the agent structured ways to create projects, deploy code, provision databases and storage, manage environments and networking, inspect logs and metrics, and troubleshoot failed services.
When to useThe skill also teaches the agent when to use the CLI, local MCP, hosted MCP, or Railway’s API. Local MCP fits when a logged-in machine and current project state matter; hosted MCP fits browser OAuth without a local CLI. Treat deployment, variable, and production-log access as sensitive.
What you needA Railway account; the CLI handles deploys.
InstallPluginPluginPluginMCP
PagerDuty logo

​
PagerDuty

Incident response and on-call context
35Kestimated installs
What it isPagerDuty’s official integration connects an agent to your incident-response platform - incidents, on-call schedules, services, and escalation policies - through a hosted MCP server, packaged as a plugin for Claude and Cursor and available as a generic MCP route elsewhere.
When to useDuring an incident the agent can pull who is on call, what changed, and which services are affected without leaving the terminal; outside incidents it turns schedule and service questions into one-line queries. Write operations reach real incidents and escalation policies, so scope API access deliberately.
What you needA PagerDuty account with Advanced Permissions; what the agent can touch follows your user’s permissions.

Pulumi logo

​
Pulumi

Infrastructure as code in real languages
25Kestimated installs
What it isPulumi’s official agent surface: a hosted MCP server for live stack, resource, registry, and policy context, paired with a collection of published skills for authoring, previewing, and deploying infrastructure-as-code programs in general-purpose languages.
When to useUse the MCP for live Pulumi Cloud work and the skills when the need is authoring guidance rather than cloud access. Previews are safe to run freely, but deployments follow your cloud credentials, so gate real deploys behind review and keep token and organization scope tight.
What you needA Pulumi Cloud account and token for the hosted MCP; the skills are open source.
