DEVELOPER DOCUMENTATION / Upstash
Context7 MCP
Resolves a library identity and retrieves documentation relevant to a specific coding question through Context7's hosted index.
“Up-to-date Code Docs For Any Prompt”
01 / THE REASONING
Why this made the selection.
- Separates library identification from documentation retrieval, making the selected upstream library visible before an answer is assembled.
- Accepts a task-specific query rather than returning an undifferentiated documentation dump.
02 / THE REVIEW RECORD
What we actually inspected.
Source review has boundaries.
A clear record is more useful than a “safe” badge.
Material inspected
- README.md: setup flow, hosted endpoint, tool arguments and content disclaimer.
- package.json: TypeScript monorepo and published MCP package identity.
- LICENSE: MIT terms for the adapter repository.
- packages/mcp/src/index.ts
- packages/mcp/package.json
Our findings
- The two documented tools have different roles: resolve-library-id selects a library, while query-docs retrieves relevant material for a known ID.
- The current setup command can install either CLI/Skills or MCP mode; choosing the mode is part of setup.
- A local adapter is not an offline documentation index.
Not established by this review
- Server startup, authentication and tool execution were not tested.
The review applies to the material and revision named here. A newer upstream release can change its behavior.
03 / PUT IT TO WORK
Connect a server deliberately.
DOCUMENTED COMMAND
npx ctx7 setupCopying does not execute this command. It may retrieve a newer version than the reviewed source.
- Run the official setup command and select MCP mode, or configure the documented https://mcp.context7.com/mcp endpoint manually.
- Complete OAuth/API-key setup through the official dashboard and client instructions; do not put account credentials in a shared configuration.
Before you start
- A compatible MCP client.
- Node.js for the setup CLI; a Context7 account/API key is recommended for higher service limits.
04 / FOLLOW THE EVIDENCE
The source trail.
Our notes are separate from the original resource.
Check upstream before adopting a new version.
