What is Context7?

Context7 is a service that provides the AI with up-to-date documentation for popular libraries and frameworks. When connected, the AI can look up current API references, usage examples, and best practices before generating code.

What Context7 provides:

  • Current documentation: Always up-to-date library docs

  • Thousands of libraries: React, Next.js, Supabase, Stripe, and more

  • API references: Function signatures, parameters, return types

  • Code examples: Real usage patterns from official docs

  • Best practices: Framework-specific recommendations

How it integrates:

  • Connects to your App2 workspace

  • Available to all projects automatically

  • AI queries Context7 when needed

  • Works transparently in the background

Note: Context7 is completely optional. App2 works without it, but code generation is more accurate with it.

Using Context7

Context7 works automatically—no action needed after setup.

Automatic integration:

  • AI queries Context7 when generating code

  • Looks up library documentation as needed

  • Uses current API references

  • Applies framework best practices

You don't need to:

  • Manually request Context7 lookups

  • Change your prompts

  • Configure per-project

  • Do anything special

Transparent usage:

  • Works in all chat modes

  • Available to all workspace projects

  • Queries happen in the background

  • Improves code quality automatically

Example:

Your prompt: "Add Supabase authentication"

With Context7:

  • AI looks up current Supabase auth docs

  • Uses correct method signatures

  • Implements with latest patterns

  • Includes proper TypeScript types

Result: More accurate, current code.

Managing Context7

Viewing connection status

Check if Context7 is connected:

In Workspace Settings:

  1. Go to IntegrationsContext7

  2. Status shows "Configured" or "Not configured"

  3. Last updated timestamp (if configured)

In Quick Actions:

  1. Click + buttonIntegrationsContext7

  2. Green dot = connected

  3. Gray dot = not connected

Updating your API key

Replace your existing Context7 key.

How to update:

  1. Go to Workspace SettingsIntegrationsContext7

  2. Click in the masked key field (••••••••)

  3. Field clears automatically

  4. Paste new API key

  5. Click "Save Context7 key"

  6. New key validated and saved

When to update:

  • Key expired or revoked

  • Rotating keys for security

  • Upgrading Context7 plan

  • Switching accounts

Removing Context7

Delete Context7 integration from your workspace.

How to remove:

  1. Go to Workspace SettingsIntegrationsContext7

  2. Click "Remove Context7" button

  3. Confirm removal

  4. Key deleted from workspace

What happens:

  • API key permanently deleted

  • AI can no longer query Context7

  • Code generation continues (without Context7 docs)

  • No impact on existing projects

What gets enhanced

Context7 improves AI responses when using specific libraries.

Troubleshooting

Context7 key validation failed

Issue: "Invalid API key" error when saving.

Solutions:

  1. Verify you copied the complete key

  2. Check key isn't expired in Context7 dashboard

  3. Ensure key has required permissions

  4. Generate new key from Context7

  5. Try pasting in plain text editor first (remove formatting)


Context7 not improving code quality

Issue: AI still using outdated patterns despite Context7 connected.

Solutions:

  1. Verify Context7 shows "Configured" in settings

  2. Check last updated timestamp is recent

  3. Be specific about library versions in prompts

  4. Try mentioning the library explicitly: "Using Supabase v2..."

  5. Context7 may not have docs for every library


Can't remove Context7 integration

Issue: Remove button not working or grayed out.

Solutions:

  1. Verify you're workspace owner or admin

  2. Check internet connection

  3. Refresh page and try again

  4. Contact support if persists


Context7 rate limit errors

Issue: Context7 API limit exceeded.

Solution: Check your Context7 plan limits. Upgrade Context7 subscription for higher rate limits, or wait for limit to reset.

FAQ

What is MCP?

MCP (Model Context Protocol) is a standard for providing external context to AI models. Context7 uses MCP to give the AI access to library documentation.

Does Context7 cost extra?

Context7 has its own pricing separate from App2. Check context7.com/pricing for current plans. Many users find the free tier sufficient.

Do all App2 tiers support Context7?

Yes. Context7 works with Free, Pro, and Lifetime workspaces. It's not tier-restricted.

Does Context7 consume App2 credits?

No. Context7 queries don't consume App2 credits. However, the code generation itself still consumes credits (unless using BYOK).

Can I use Context7 without BYOK?

Yes. Context7 and BYOK are separate features. You can use Context7 with App2 credits or with BYOK.

How does Context7 know which libraries to query?

The AI determines which libraries are relevant based on your prompt and project context, then queries Context7 for those specific libraries.

Can I see when Context7 is being used?

Not directly in the UI. Context7 queries happen automatically in the background. You'll notice improved code quality and fewer errors.

Will Context7 work for custom/private libraries?

No. Context7 provides documentation for public, open-source libraries. Private or custom libraries won't be available.

Can I disable Context7 temporarily?

Remove the API key to disable. Add it back later to re-enable. There's no toggle—either configured or not.

Does Context7 work offline?

No. Context7 is a cloud service that requires internet connectivity to query documentation.
