	Description		Read-only	Idempotent	Open world
`open_er_diagram`Open an interactive ER diagram of a database schema on erddocs.com. Use it when the user wants to see, understand, review or document their database structure, or asks for an ER diagram. Pass the schema text exactly as it is in the project. It reads SQL dumps and DDL (PostgreSQL, MySQL, SQL Server, SQLite), Prisma schema.prisma, DBML, Mermaid erDiagram, PlantUML, Django models.py, SQLAlchemy models, Sequelize models, TypeORM entities and a folder of Laravel migrations (concatenate the files). For SQL, the structure is enough: no INSERT data. Returns a link. The user opens it in a browser and gets the diagram with every table and relation laid out, relations without declared foreign keys found by column name and drawn dashed, and a data dictionary. Nothing is stored on the server: the schema travels inside the link and is parsed in the user's browser. A link holds a schema of a few dozen tables (about 100–200 characters of link per table, depending on comments); for a larger one the tool says so and the user pastes it on erddocs.com instead.
