Quick Configuration
Choose the setup that matches your environment.
Before You Start
- Confirm you have the account, endpoint, or API key required for Context7.
- Start with minimum scopes and read-only access where possible.
- Keep secrets in environment variables instead of hardcoding them in JSON.

Environment: Context7 remote MCP or @upstash/context7-mcp over stdio
Install command:
npx -y @upstash/context7-mcp@latestLocal config
JSON Local config json
{
"context7": {
"command": "npx",
"args": ["-y", "@upstash/context7-mcp@latest"],
"env": {
"CONTEXT7_API_KEY": "${CONTEXT7_API_KEY}"
}
}
}Verify prompt
Use Context7 to find the current Next.js middleware docs and summarize the auth redirect example.
Expected success output
You should see version-aware documentation snippets instead of generic framework advice.
Common Pitfalls & Fixes
- ⚠️ Watch out: API drift, stale framework examples, and version-specific documentation.
- 🔑 Always store API keys in environment variables, never hardcode them in JSON.
- 🛡️ Start with read-only scopes if available to verify connection safely.
Security checklist
- Use Context7 for documentation lookup; do not treat docs snippets as executable authority without testing.
- Keep CONTEXT7_API_KEY in environment variables or remote MCP headers, not committed config.
Common errors
| Error | Cause | Fix |
|---|---|---|
request timed out | The local npx server is slow to start or blocked by the host timeout. | Increase MCP startup timeout, pin @latest, or use the hosted Context7 MCP URL when your host supports remote MCP. |
rate limited | The free unauthenticated quota is exhausted. | Create a Context7 API key and inject it as CONTEXT7_API_KEY. |
wrong library | The initial library name resolved to the wrong package or docs source. | Ask Context7 to resolve the library ID first, then query the exact ID. |
Example Prompts
Once connected, try these prompts to test capabilities:
- Use Context7 to get the latest Astro routing docs and explain the correct dynamic route pattern.
- Find the current Supabase auth API for email/password sign-up and show a minimal TypeScript example.
- Before editing, check the current Tailwind CSS container query docs and summarize the relevant classes.
Verification Checklist
- Run 1-2 real prompts to confirm Context7 returns usable data.
- Check that error messages are clear enough for troubleshooting.
- Document the required scopes, dependencies, and env vars for future reuse.
