Context7
Documentation quality layer that fetches current, version-specific library documentation. Resolves library IDs and returns focused doc sections so your agent works with accurate API references.
“Solves the stale documentation problem. When your agent hallucinates an API that changed two versions ago, Context7 fetches the current docs. Simple, focused, and effective.”
INSTALL THIS SERVER
{
"mcpServers": {
"context7": {
"command": "npx",

2 TOOLS AVAILABLE
OUR ASSESSMENT
- Fetches current, version-specific documentation
- Covers major frameworks and libraries (React, Next.js, Prisma, etc.)
- Lightweight (2 tools, minimal overhead)
- No authentication required
- Coverage depends on the Context7 index (growing, with selective library coverage)
- Documentation quality varies by library
Read-only. Fetches public documentation from the Context7 cloud index. No credentials or sensitive data involved.
Keeping your agent current on library APIs and framework documentation

SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 2 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 2 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
| Source | Their rating | Their star count | Their downloads | Last synced |

// Counts are directory-reported; we don't adjust them. Discrepancies usually come from different snapshot times or star-caching.
