Context7 Documentation Lookup

Retrieve current documentation and code examples from Context7 using the resolve-library-id and query-docs tools that ship with this extension.

When to use

Reach for these tools whenever a question involves a specific library, framework, SDK, CLI tool, or cloud service. Examples:

"How do I configure caching in Next.js 16?"
"What's the syntax for Prisma's findMany with relations?"
"Show me a working Tailwind v4 install for a Vite app."
"How do I rate-limit with @upstash/ratelimit?"

Workflow

Resolve the library ID. Call resolve-library-id with the library name and what to look up in the library's documentation. The tool returns matching libraries with their Context7 IDs (/org/project format), descriptions, snippet counts, and quality scores. Pick the best match — prioritize official sources, name match, and high benchmark scores.
Query the docs. Call query-docs with the chosen library ID and what to look up in the library's documentation, scoped to a single concept — if the question spans multiple distinct concepts, make a separate call per concept with the same library ID, unless the question is about how the concepts interact. The tool returns documentation snippets and code examples.
Answer. Cite the library ID you used and quote code examples verbatim when relevant.

If the user supplies a library ID in /org/project or /org/project/version format directly, skip step 1 and call query-docs immediately.

Constraints

Do not call either tool more than 3 times per question.
Do not pass API keys, passwords, credentials, personal data, or proprietary code as the query argument — it is sent to the Context7 API.
Authentication uses the CONTEXT7_API_KEY environment variable. Get a key at https://context7.com/dashboard if requests fail with an auth error.

21
22	Retrieve current documentation and code examples from [Context7](https://context7.com) using the `resolve-library-id` and `query-docs` tools that ship with this extension.
23
24	## When to use
25
26	Reach for these tools whenever a question involves a specific library, framework, SDK, CLI tool, or cloud service. Examples:
27
28	- "How do I configure caching in Next.js 16?"
29	- "What's the syntax for Prisma's `findMany` with relations?"
30	- "Show me a working Tailwind v4 install for a Vite app."
31	- "How do I rate-limit with `@upstash/ratelimit`?"
32
33	## Workflow
34
35	1. Resolve the library ID. Call `resolve-library-id` with the library name and what to look up in the library's documentation. The tool returns matching libraries with their Context7 IDs (`/org/project` format), descriptions, snippet counts, and quality scores. Pick the best match — prioritize official sources, name match, and high benchmark scores.
36	2. Query the docs. Call `query-docs` with the chosen library ID and what to look up in the library's documentation, scoped to a single concept — if the question spans multiple distinct concepts, make a separate call per concept with the same library ID, unless the question is about how the concepts interact. The tool returns documentation snippets and code examples.
37	3. Answer. Cite the library ID you used and quote code examples verbatim when relevant.
38
39	If the user supplies a library ID in `/org/project` or `/org/project/version` format directly, skip step 1 and call `query-docs` immediately.

41	## Constraints
42
43	- Do not call either tool more than 3 times per question.
44	- Do not pass API keys, passwords, credentials, personal data, or proprietary code as the `query` argument — it is sent to the Context7 API.
45	- Authentication uses the `CONTEXT7_API_KEY` environment variable. Get a key at https://context7.com/dashboard if requests fail with an auth error.
