Seedweaver Mcp
Generate realistic relational test datasets that respect foreign keys and schema constraints so agents can seed local DBs for integration and E2E tests.
Overview
SeedWeaver MCP is a Ship-phase MCP server that generates schema-aware relational test data with valid foreign keys for any MCP client.
What is this MCP server?
- Schema-aware relational data generation
- Working foreign keys across related tables
- Works with any MCP-compatible client
- stdio npm package seedweaver-mcp
- Reduces hand-written SQL seed scripts for agents
- Published as seedweaver-mcp npm package v0.2.0 with stdio transport
- Described as schema-aware with working foreign keys for relational tests
What problem does it solve?
Flaky tests and slow agent debugging often trace to broken hand-written seeds that violate foreign keys and schema rules.
Who is it for?
Solo backend builders who need fast, FK-safe database seeds while writing or fixing integration tests.
Skip if: Analytics-only pipelines, document stores without relational constraints, or production data masking requirements.
What do I get? / Deliverables
After you add seedweaver-mcp, your agent can propose coherent multi-table fixtures aligned to your schema for local and CI testing.
- Multi-table seed datasets with coherent foreign keys
- Reduced manual SQL fixture maintenance
- Faster agent-assisted test setup and staging resets
Recommended MCP Servers
Journey fit
SeedWeaver shines when you are preparing to ship reliable software—populating databases for tests and demos is a Ship-phase testing concern, not greenfield ideation. Schema-aware fixture generation is test data infrastructure, which maps directly to the testing subphase under Ship.
How it compares
Database fixture MCP generator, not a migration framework or ORM codegen skill.
Common Questions / FAQ
Who is SeedWeaver MCP for?
Developers shipping relational apps who want MCP agents to create consistent test rows without manually maintaining seed SQL.
When should I use SeedWeaver MCP?
Use it in Ship/testing when schemas exist and you need realistic datasets for integration tests, staging, or agent-driven QA setup.
How do I add SeedWeaver MCP to my agent?
Install the npm package seedweaver-mcp, configure stdio transport in your MCP client, and register io.github.FixtureForge/seedweaver-mcp per your editor’s MCP docs.
