Top 10 MCP Servers Worth Installing Now
We re-ranked the list around maintained projects, official support, current API drift, and real OpenClaw workflows. Stars are a signal, not the whole ranking.
Last reviewed: 2026-05-25. Verify against the latest OpenClaw and MCP server docs before production use.
Who this is for / not for
- You have OpenClaw running and need a sane first MCP stack
- You want to balance value, setup effort, and security
- You need a way to narrow config failures before adding more servers
Avoid this
- Installing every shiny MCP at once
- Opening data access before deciding what AI may read
- Bypassing OAuth, token scopes, or organization security controls
Context7
Pull current library docs into coding prompts before the model invents old APIs.
GitHub (Official)
Read repos, issues, and open PRs directly via openclaw.
Filesystem (Official)
Give openclaw safe, scoped read/write access to your files.
Playwright
Reliable browser automation for screenshots, flows, and scraping.
Firecrawl
Extract clean content from websites for RAG and research workflows.
Exa
Semantic web search for high-signal sources and citations.
Supabase
Work with Supabase Postgres, auth, and storage for app backends.
PostgreSQL
Query local or remote Postgres for dashboards and reports.
Browserbase
Hosted browser sessions for automation in restricted environments.
Notion
Search, read, and summarize pages in your Notion workspace.
When existing MCPs should not own your private workflow
If your workflow needs fixed rules, private APIs, narrow permissions, or stable output, the next step is not installing more MCPs. Design a small reliable custom MCP.

The Top 10 list is not a request to install all ten. Prove filesystem first, then add Context7, GitHub, search, browser, or database MCPs one at a time.

"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "./openclaw-workspace"]
}
}
}mkdir -p openclaw-workspace
openclaw statusExpected result: OpenClaw can see the filesystem server. If this fails, do not stack more MCPs yet.
Ask these 3 questions before installing
Current combinations for specific roles.
- Is it official or actively maintained, rather than just popular a few months ago?
- Does it need a token or OAuth, and can that be handled through env vars or hosted auth?
- Can it read or write local files, repos, or production data, and can that access be narrowed?

Common selection/config errors
Too many servers at once
Symptom: OpenClaw starts slowly or several servers fail together. Cause: a full stack was pasted before one server was verified. Fix: keep one server, then add the rest back one by one. Ask for review if you cannot isolate the failing block.
API key missing
Symptom: search, GitHub, or SaaS MCPs report missing credentials. Cause: placeholders were copied as real values or env vars were not injected. Fix: use environment variables; never send raw keys for review.
OAuth failed
Symptom: auth redirect fails or callback never completes. Cause: account, scopes, callback, or organization policy mismatch. Fix: verify with official docs, then send the sanitized error if still blocked.
