Context7 for databases
Context7 is the third of three picks for databases, and it is the one you pair with a database server rather than point at the database itself. It pulls version-accurate docs and code examples into context so the agent writes correct SQL and ORM code instead of hallucinating an outdated API.
The two servers ahead of it talk to the data directly: Supabase for a Supabase project, DBHub (Postgres) for a bare Postgres instance. Context7 does not query your database. It earns its place by making the queries the others run more likely to be valid against your ORM or SQL dialect.
How Context7 fits
The mechanism is the same two tools as everywhere else: resolve-library-id maps your ORM, driver, or database product to a Context7 library ID, and query-docs returns its current documentation and examples. When the agent drafts a Prisma migration or a Postgres-specific function call, it checks the present syntax rather than the version it half-remembers.
Its limit for this task is clear: no connection, no schema introspection, no query execution. For inspecting tables and running read-only queries you want Supabase or DBHub (Postgres), which sit ahead of Context7 precisely because they touch the data. Use Context7 next to whichever one matches your stack, so the SQL or ORM code the agent produces lines up with the current API instead of a stale one.
Tools you would use
| Tool | What it does |
|---|---|
| resolve-library-id | Resolves a package or product name into a Context7-compatible library ID, ranking matches by the user's query. |
| query-docs | Retrieves up-to-date documentation and code examples from Context7 for a resolved library ID, scoped to the user's question. |
FAQ
- Does Context7 connect to my database?
- No. It has no database connection and cannot run queries or read a schema. Pair it with Supabase or DBHub (Postgres) for that, and use Context7's query-docs to keep the generated SQL and ORM code current.
- How does Context7 help with database code specifically?
- By feeding the agent up-to-date docs for your ORM or SQL dialect. resolve-library-id finds the library, query-docs returns its current examples, so a function or migration the agent writes matches today's API rather than an outdated one.
