{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What does Introspection build?","acceptedAnswer":{"@type":"Answer","text":"When the Forest back-end starts, it reads the schema of each database you connect: tables, fields, types and the relationships the database declares. Each table becomes a collection in Forest, with standard record operations and default list and detail views."}},{"@type":"Question","name":"Does it detect relationships between two databases?","acceptedAnswer":{"@type":"Answer","text":"A foreign key cannot point to another database, so Introspection has nothing to read there. Your engineers declare those links in the Forest back-end, one line per relationship. They then work like any introspected relationship."}},{"@type":"Question","name":"How does Introspection help us code actions?","acceptedAnswer":{"@type":"Answer","text":"Forest Actions are written against the collections Introspection builds. On Node.js, the Forest back-end also generates a typing file, so collection, field and relationship names autocomplete in your editor and in your AI coding agent."}},{"@type":"Question","name":"How do AI agents use Introspection?","acceptedAnswer":{"@type":"Answer","text":"Before an AI agent acts, it reads through the MCP server which collections exist and how they relate, inside each database and across the links your engineers declared. It finds a customer's accounts, cards and cases on its own."}},{"@type":"Question","name":"What happens when our schema changes?","acceptedAnswer":{"@type":"Answer","text":"Restart the Forest back-end after a migration and the new tables and fields appear in Forest. The schema snapshot, .forestadmin-schema.json, lives in your repository, so the change shows up in a diff before it reaches production."}},{"@type":"Question","name":"Does Forest see our data?","acceptedAnswer":{"@type":"Answer","text":"The Forest back-end runs in your infrastructure and reads your databases in place. For SQL databases and Snowflake, Introspection reads catalog metadata only. MongoDB has no declared schema, so the Forest back-end samples a set number of documents to infer one, still inside your infrastructure."}},{"@type":"Question","name":"Which databases does Introspection work with?","acceptedAnswer":{"@type":"Answer","text":"PostgreSQL, MySQL, MariaDB and SQL Server through the SQL datasource, along with MongoDB, Snowflake and ORM-based datasources such as Sequelize, Mongoose and ActiveRecord. See the full list in the docs."}}]}
