The current status is shown at the top of this page. You can also see the 30-day uptime history in the chart above.\n\n## Implementation notes\n\n### When to use DeepWiki MCP\n\nDeepWiki MCP (by Cognition, the Devin team) answers architecture-level questions about any public GitHub repository: 'how does authentication flow through this codebase', 'where is rate limiting implemented', 'what's the plugin API surface'. It draws on DeepWiki's pre-generated AI wikis rather than raw file access, so answers synthesize across files instead of quoting one. Use it for dependency due-diligence, onboarding onto unfamiliar codebases, and 'should we adopt this library' research.\n\n### Common pitfalls\n\n- Index quality tracks repo popularity. Major repos (react, kubernetes, django) have excellent wikis; a 40-star niche library may have a thin or stale index. Cross-check critical claims against the actual source.\n- The index is generated periodically, not live. A repo that just landed a big refactor may be described in its pre-refactor shape for a while. For bleeding-edge accuracy, pair with GitMCP which reads the current default branch.\n- Private repositories are not accessible through the free public endpoint — that's a Devin product feature. Public repos only here.\n\n### Quick start (bash)\n\n```\nclaude mcp add deepwiki --transport http https://mcp.deepwiki.com/mcp\n```\n\n### From our monitoring\n\nInitialize handshakes run 400-700ms in our checks — slower than the docs servers, consistent with heavier backend work per session. Availability has been solid since we began monitoring.\n\n## Embed this badge\n\nAdd a live status badge to your README, docs, or website.\n\n### Markdown\n\n```\n[![DeepWiki MCP Status](https://freeapi-builder.a10ayassine.workers.dev/badge/mcp-deepwiki.svg)](https://freeapi.watch/mcp-deepwiki)\n```\n\n### HTML\n\n```\n<a href=\"https://freeapi.watch/mcp-deepwiki\"><img src=\"https://freeapi-builder.a10ayassine.workers.dev/badge/mcp-deepwiki.svg\" alt=\"DeepWiki MCP Status\"/></a>\n```\n\n", "url": "https://wpnews.pro/news/deepwiki-mcp-is-back-online", "canonical_source": "https://freeapi.watch/mcp-deepwiki", "published_at": "2026-07-23 12:40:16+00:00", "updated_at": "2026-07-23 16:05:46.016758+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools", "generative-ai"], "entities": ["Cognition", "DeepWiki MCP", "Devin", "GitHub"], "alternates": {"html": "https://wpnews.pro/news/deepwiki-mcp-is-back-online", "markdown": "https://wpnews.pro/news/deepwiki-mcp-is-back-online.md", "text": "https://wpnews.pro/news/deepwiki-mcp-is-back-online.txt", "jsonld": "https://wpnews.pro/news/deepwiki-mcp-is-back-online.jsonld"}}
