majiayu000 MCP Server Catalog - The Arsenal
[!TIP] This catalog lists specialized MCP Servers that can be deployed to extend Agent capabilities. Source: "Top Open-Source MCP Servers" (Transcript).
1. HuggingFace MCP
Role: The Gateway to Models & Data.
- Capabilities: Access datasets, run models, and interact with Spaces dynamically.
- Why: Use for specialized inference or fetching data without leaving the agent context.
- Mode: Dynamic discovery of tools.
2. Octagon Deep Research
Role: Unlimited Parallel Researcher.
- Capabilities: 8-10x faster than traditional search. Runs parallel deep dives across broad domains.
- Why: For complex market research or academic queries requiring synthesis of 100+ sources.
3. AllVoice Lab (Damn Many Mercy)
Role: High-Fidelity Voice & Video.
- Capabilities: Text-to-Speech, Voice Cloning (seconds), Multilingual Dubbing, Subtitle Removal.
- Why: Generate multimedia assets or localize content programmatically.
4. Android MCP
Role: Mobile Device Control.
- Capabilities: Uses ADB to control Android phones/emulators. Launch apps, tap, screenshot, inspect UI tree.
- Why: E2E Mobile Testing or automating mobile-only workflows.
5. Deep View MCP
Role: Large-Scale Codebase Understanding.
- Capabilities: Feeds entire repositories (via
repomix) to Gemini Flash/Pro for "Global Context" answers. - Why: "Refactor class X" knowing how it affects the entire system, not just the open file.
6. Combine MCP
Role: The Server Aggregator.
- Capabilities: Merges multiple MCP servers into one endpoint. Handles namespace conflicts (e.g.,
serverA_searchvsserverB_search). - Why: Bypass client limits on connection count.
7. Google Admin MCP
Role: Workspace Automator.
- Capabilities: Manage Users, Groups, Suspensions, Password Resets via Google Admin Directory API.
- Why: Automate HR Onboarding/Offboarding flows.
8. JSON MCP
Role: Structured Data Handler.
- Capabilities: Split, Merge, Filter, and Validate massive JSON files without loading them entirely into context.
- Why: Manipulating large data exports efficiently.
9. Browser MCP
Role: Stealthy Local Automation.
- Capabilities: Uses existing Chrome profile. No login needed. Detects accessibility tree for precise clicking.
- Why: Automating web tasks that require auth (Logged-in sessions) without triggering bot detection.
10. Bright Data MCP
Role: Unblocked Web Access.
- Capabilities: Enterprise-grade proxying to bypass Captchas, Geo-blocks, and IP bans.
- Why: When "Fetch URL" fails due to 403 Forbidden or Cloudflare checks.
11. Notion MCP
Role: Knowledge Management & Task Sync.
- Capabilities: Read pages, manage databases (tasks), generate task lists from code analysis.
- Why: Keep project management (Notion) in sync with code status automatically.
12. GitHub MCP
Role: DevOps & Code Collaboration.
- Capabilities: Manage Repos, Pull Requests, Issues, Actions.
- Why: Create PRs directly from the Agent (e.g., "Refactor this and open a PR").
13. TestSprite MCP
Role: Autonomous Testing Agent.
- Capabilities: Scans code, generates test plans, executes tests (Playwright/Python), and reports issues.
- Why: "Unit Testing on Autopilot" - detects regressions without human intervention.
14. Linear MCP
Role: Agile Project Management.
- Capabilities: Manage tickets/issues for teams (similar to Notion but for Agile/Scrum).
- Why: Team-based task tracking integration.
15. Context7 MCP
Role: Live Documentation Context.
- Capabilities: Fetches latest documentation (e.g., Next.js 15 breaking changes) to prevent hallucinations.
- Why: Ensures code generation uses up-to-date syntax (avoiding deprecated APIs).
16. Ref MCP
Role: Context-Efficient Documentation.
- Capabilities: Alternative to Context7. combination of web search, scraping, and code search. Uses semantic search to expose only relevant snippets, saving tokens.
- Why: When Context7 is too heavy on context/tokens.
17. Docker MCP
Role: The Sandbox & Context Optimizer.
- Capabilities: Runs verified MCPs in a sandbox. Reduces context bloat by loading only required tools for a specific query ("Code Mode").
- Why: Security (sandbox) and Efficiency (prevent context limit errors with many tools).
18. Shadcn Registry MCP
Role: UI Component Installer.
- Capabilities: Install shadcn/ui components directly. Supports custom registries (Aceternity, Magic UI).
- Why: "Add a pricing table" -> Installs the actual component code + dependencies automatically.
19. Google Cloud MCP Suite
Role: Cloud Infrastructure Control.
- Capabilities:
- Maps: Location-based grounding.
- BigQuery: Query enterprise data without exposing sensitive rows to context.
- Compute/Kubernetes: Manage VMs and containers.
- Why: Full stack cloud management from the agent.
20. Obsidian MCP
Role: Local Knowledge Base.
- Capabilities: Manage Obsidian pages/tasks (Search, Read, Write).
- Why: For users who prefer local-first notes over Notion.
