## Implementation notes

### When to use DeepWiki MCP

DeepWiki 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.

### Common pitfalls

- 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.
- 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.
- Private repositories are not accessible through the free public endpoint — that's a Devin product feature. Public repos only here.

### Quick start (bash)

```
claude mcp add deepwiki --transport http https://mcp.deepwiki.com/mcp
```

### From our monitoring

Initialize 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.
