Use SynthForge from your AI agent
Hosted MCP connects Claude, Cursor, or any Streamable HTTP client. Describe the dataset you need and download multi-table synthetic data with foreign keys intact.
Endpoint: https://mcp.synthforge.io/mcp
Describe, then download
One tool takes a plain-English description and returns a downloadable multi-table dataset.
Real relational data
Multi-table schemas with foreign-key integrity, cardinality ratios, and exports for Postgres, MySQL, SQL Server, SQLite, and more.
Credits while you try it
Your first API key includes 250 credits. The web app and browser-approved MCP get a free row allowance on every dataset, and you can buy more credits any time from Settings.
Get started in four steps
- 1
Create a free account
Sign in at the web app. The first 20,000 rows of a dataset generated in the browser are free; larger runs use credits, the same as the API.
Launch App → - 2
Mint an API key (250 free credits)
In Settings → API keys, create a key (sfk_live_…). Your first key automatically receives 250 free product credits so agents can generate schemas and datasets immediately. Copy the secret once.
Open Settings → - 3
Need more credits?
Personal API-key jobs use product credits from the first row. AI schema design costs API keys 8 credits per table, up to 80; it is free in the web app and for browser-approved MCP connections. Generating a dataset with an API key costs 2 credits plus 1 per 25,000 rows. Failed and cancelled jobs cost nothing. Credits are a cent each: $5 buys 500. Bigger packs add bonus credits, so $50 buys 6,000 and $100 buys 13,000. Buy a pack any time from Settings, or have your agent call the buy_credits tool for a checkout link.

FAQ
What is Hosted MCP?
You can call SynthForge from an MCP-compatible agent at mcp.synthforge.io. Describe the data you need, get multi-table synthetic data with foreign keys intact, and download the result without learning every REST endpoint.
Do I get credits automatically?
Yes. Creating your first API key grants 250 free product credits. That is enough for several rounds of generating a schema and a dataset from it. See below for how to buy more when you need them.
Is the web app free?
Yes, up to a generous point. The first 20,000 rows of a dataset generated in the browser are free, and larger runs use credits. Personal API keys and CLI/SDK access use credits from the first row. Hosted MCP connected the way claude.ai connects, by approving access in a browser, gets the same free allowance a web session does.
How do I get more credits?
Buy a credit pack any time from Settings → Credits in the app; credits are a cent each and $5 buys 500. If your agent hits a 402, it can call the buy_credits MCP tool for a checkout link instead of stopping to ask you.
What can my agent do?
The primary tool is description_to_dataset: describe the data you need, get a schema, generate rows, and receive a download URL (and often an embedded ZIP for hosts that support attachments). You can also generate a schema on its own, generate from an existing schema, list assets, and poll job status.
