Schema-aware relational test data generator with working foreign keys, for any MCP client.
Schema-aware relational test data generator with working foreign keys, for any MCP client.
Paste your CREATE TABLE SQL (or a JSON schema) and SeedWeaver generates seed data where foreign keys actually resolve to real primary keys, unique constraints are respected, and values are realistic (names, emails, dates, decimals). Unlike generic mock-data tools that spit out statistically random junk, SeedWeaver understands the relationships in your schema.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
| Tool | What it does |
|---|---|
| analyze_schema | Parse a schema (SQL DDL or JSON) and report tables, columns, relationships, and generation order. Run this first to confirm SeedWeaver reads your schema correct |
| generate_seed_data | Generate coherent test data. Returns SQL INSERTs (default), JSON, or CSV. |
