@MCPlugStoreThe Definitive List of MCP Servers You Should Know in 2025
The Model Context Protocol (MCP) ecosystem has exploded in 2025. What began as a niche standard for connecting AI agents to external tools has become the backbone of the agentic web. Whether you are building autonomous coding assistants, data analysis pipelines, or customer-service bots, choosing the right MCP servers determines how capable your agent actually is.
We compiled this directory after reviewing hundreds of servers listed on MCPlug's marketplace. Each entry includes a short description, primary use-case, and a direct link so you can install or purchase the skill in seconds.
Whether you are assembling a coding copilot, an autonomous DevOps bot, or a multi-modal research assistant, this list will help you identify the servers that deserve a place in your agent's toolkit. We organized the list by category so you can jump straight to the section that matters most.
Coding and Development Tools
1. GitHub Agent Server
The GitHub Agent Server gives your AI agent full read-write access to repositories, pull requests, issues, and Actions workflows. It handles authentication, pagination, and rate-limiting behind the scenes so your agent can focus on shipping code. Popular among teams that want their coding assistant to open PRs, review diffs, and merge automatically.
2. GitLab CI/CD Connector
Similar to the GitHub server but purpose-built for GitLab. It exposes pipeline triggers, merge-request management, and container-registry operations. Ideal for enterprises that standardize on GitLab for their DevOps toolchain.
3. CodeSearch Pro
CodeSearch Pro indexes large monorepos and exposes semantic code search to your agent. Instead of grepping through millions of lines, your agent sends a natural-language query and gets back ranked, context-rich snippets. Supports TypeScript, Python, Go, Rust, and Java out of the box.
4. Docker Compose Manager
This server lets agents spin up, tear down, and inspect Docker Compose stacks programmatically. Useful for agents that need to run integration tests, preview deployments, or manage local development environments on behalf of engineers.
5. NPM Registry Bridge
Gives your agent the ability to search npm, inspect package metadata, compare versions, and even publish packages. A must-have for JavaScript-focused coding agents that need real-time dependency information.
Data and Analytics
6. PostgreSQL Query Agent
Connects your agent directly to a PostgreSQL database with configurable read/write permissions. It supports parameterized queries, schema introspection, and result streaming for large datasets. Security-first design ensures agents cannot drop tables or alter schemas unless explicitly permitted.
7. Snowflake Data Warehouse Connector
Enterprise-grade MCP server for Snowflake. Your agent can run analytical queries, manage warehouses, and pull data into downstream workflows. Built-in cost guardrails prevent runaway queries from burning through your Snowflake credits.
8. Google Sheets Sync
A lightweight server that lets agents read, write, and format Google Sheets. Perfect for business-automation agents that need to update dashboards, generate reports, or pull configuration from spreadsheets maintained by non-technical stakeholders.
9. CSV and Excel Parser
Handles local file parsing for CSV, TSV, XLSX, and ODS formats. The agent can filter, aggregate, and transform tabular data without loading everything into memory. Excellent for data-cleaning pipelines.
Web Browsing and Research
10. Headless Browser Pro
Gives your agent a full Chromium instance behind an MCP interface. It can navigate pages, fill forms, take screenshots, and extract structured data. Anti-bot detection handling is built in, making it reliable for scraping dynamic SPAs.
11. Web Search Aggregator
Aggregates results from multiple search engines — Google, Bing, and DuckDuckGo — and returns deduplicated, ranked results with snippets. Agents use this when they need to research a topic, fact-check claims, or gather competitive intelligence.
12. ArXiv and Papers Server
Searches academic papers on arXiv, Semantic Scholar, and PubMed. Returns abstracts, citation counts, and PDF download links. Research-focused agents rely on this to stay current with the latest publications.
Communication and Productivity
13. Slack Workspace Agent
Connects to Slack via OAuth and exposes channel messaging, thread replies, reactions, and file uploads. Useful for agents that triage support channels, summarize conversations, or post automated updates.
14. Email Outreach Server
Manages email sending and receiving through SMTP/IMAP or API providers like SendGrid and Postmark. Includes template rendering, scheduling, and bounce tracking. Sales and marketing agents use this to run outreach campaigns autonomously.
15. Notion Knowledge Base
Reads and writes Notion pages, databases, and blocks. Your agent can maintain a living knowledge base, update project trackers, or pull context from existing documentation without any human intervention.
16. Calendar Scheduler
Integrates with Google Calendar and Outlook to check availability, create events, send invites, and handle rescheduling. Executive-assistant agents pair this with email and Slack servers to manage calendars end-to-end.
DevOps and Infrastructure
17. AWS Cloud Manager
Wraps the AWS SDK behind a safe MCP interface. Agents can provision EC2 instances, manage S3 buckets, query CloudWatch metrics, and deploy Lambda functions. Role-based access control ensures agents only touch the resources you allow.
18. Kubernetes Operator Agent
Lets agents interact with Kubernetes clusters: deploy workloads, scale replicas, inspect pod logs, and roll back failed deployments. Built for SRE agents that monitor production and respond to incidents without waking up on-call engineers.
19. Terraform Plan Runner
Executes Terraform plans in a sandboxed environment, returning diffs and cost estimates before applying changes. Infrastructure-as-code agents use this to propose infra changes in pull requests with full visibility into what will change.
Design and Content
20. Figma Design Bridge
Reads Figma files, extracts components, and generates design tokens or code snippets. Front-end agents use this to translate mockups into React or HTML/CSS without manual handoff from designers.
21. Image Generation Hub
Unified interface to DALL-E, Stable Diffusion, and Midjourney APIs. Agents can generate, edit, and upscale images through a single MCP call. Content-creation agents pair this with text-generation to produce complete blog posts with illustrations.
22. Video Transcription Server
Transcribes audio and video files using Whisper and returns timestamped, speaker-diarized text. Media agents use this to generate show notes, subtitles, and searchable archives from podcast and meeting recordings.
Finance and Payments
23. Stripe Payments Agent
Manages Stripe customers, subscriptions, invoices, and payouts through MCP. Commerce agents use this to handle checkout flows, issue refunds, and generate financial reports without direct Stripe dashboard access.
24. Crypto Wallet Connector
Interacts with Ethereum, Solana, and Bitcoin wallets for balance checks, transaction history, and token transfers. Agents operating in Web3 use this to manage treasury or execute on-chain actions based on off-chain triggers.
Monitoring and Observability
25. Sentry Error Tracker
Connects agents to Sentry for real-time error monitoring. Agents can query recent exceptions, view stack traces, assign issues to team members, and mark errors as resolved. SRE and on-call agents use this to triage production errors autonomously.
26. Datadog Metrics Agent
Pulls metrics, dashboards, and alert statuses from Datadog. Agents can correlate metric spikes with recent deployments, auto-generate incident reports, and trigger runbooks when thresholds are breached. An essential server for any infrastructure-focused agent.
