Use the Synthbrew MCP server in Claude Code to provision schemas, sources, API keys, and runtime docs from your terminal agent.

​
Prerequisites

  • Claude Code installed
  • A Synthbrew public API key

​
Add the MCP server

Run: 
claude mcp add --transport stdio --scope user \
  --env SYNTHBREW_API_KEY=sb_api_... \
  --env SYNTHBREW_API_URL=https://api.synthbrew.com/api \
  synthbrew -- npx -y @synthbrew/agent
Use --scope project instead if you want Claude Code to write a shared .mcp.json file in the current project.

​
Test the connection

Inside Claude Code, run: 
/mcp
Then ask: 
Use Synthbrew to generate a schema for a CRM with companies, contacts, deals, activities, and tasks. Validate it first, then create a populated source and return the connection details.
Claude Code should validate the schema before creating resources.

​
Project config alternative

You can also add Synthbrew manually to .mcp.json: 
{
  "mcpServers": {
    "synthbrew": {
      "command": "npx",
      "args": ["-y", "@synthbrew/agent"],
      "env": {
        "SYNTHBREW_API_KEY": "${SYNTHBREW_API_KEY}",
        "SYNTHBREW_API_URL": "https://api.synthbrew.com/api"
      }
    }
  }
}
