Frequently asked
- What are the best JavaScript mcp servers?
- By recorded GitHub star count, firecrawl-mcp-server, browser-tools-mcp and Talk to Figma MCP (Grab) lead the JavaScript mcp servers in this index of 11. The full list is below; star count does not prove suitability or continued maintenance. Sponsorship does not affect its order.
- Are these JavaScript mcp servers open source and free?
- These records have recognized open-source software licenses recorded and are written primarily in JavaScript in this index. MIT is the most common licence here, on 9 of 11, across 2 licences in total. Check each license and deployment requirements. Hosting, model, API, and managed-service costs may apply.
- Why choose JavaScript mcp servers specifically?
- Staying in your team's primary language — JavaScript — can help your team inspect and modify code it understands. Repository language does not establish supported user languages, SDKs or an offline deployment. 7 of these 11 have a recorded push within 90 days. A quiet repository alone does not establish whether the project is complete, supported or abandoned.
