Configuration

All configuration is managed using environment variables. When running locally from source, you can define them in a .env file in the root directory. When running via npx, they are passed as environment variables in your client config JSON.

Tool Profiles

The active tool set is gated by the TOOL_PROFILE environment variable.

Profile	Level	Purpose
core (default)	L0 + L1	Standard read-only and inspection tools (schematic components, nets, stackup, layers, export Gerbers).
pro	L1+	Includes Gerber, Pick & Place, BOM, schematic/PCB PDF, and netlist export tools.
full	L0-L1	Adds the generic controlled documented easyeda_api_call tool, enabling custom interactions. Mutation calls require confirmation.
dev	Dev	Adds diagnostic component probes and WebSocket bridge diagnostics.

Configure this in your client environment configuration:

"env": {
  "TOOL_PROFILE": "pro"
}

Supplier Sourcing Configuration

Suppliers are optional and disabled by default. Set the following variables to enable integrations:

LCSC (Electronic Components)

• JLCSEARCH_ENABLED=true (Default is true, does not require API keys for basic inventory lookups).

Mouser Electronics

• MOUSER_ENABLED=true
• MOUSER_API_KEY=your-mouser-api-key

DigiKey Electronics

• DIGIKEY_ENABLED=true
• DIGIKEY_CLIENT_ID=your-client-id
• DIGIKEY_CLIENT_SECRET=your-client-secret

JLCPCB Fabrication

• JLCPCB_MODE=approved_api
• JLCPCB_CLIENT_ID=your-client-id
• JLCPCB_CLIENT_SECRET=your-client-secret

Transport Configuration

By default, the server uses standard I/O (stdio) transport. To run as an HTTP server:

TRANSPORT=http
HTTP_HOST=127.0.0.1
HTTP_PORT=3000
HTTP_RATE_LIMIT_MAX=100

Production Security for HTTP

For remote HTTP deployments, OAuth 2.0 validation can be enforced:

OAUTH_ENABLED=true
OAUTH_ISSUER=https://your-identity-provider.com
OAUTH_JWKS_URI=https://your-identity-provider.com/.well-known/jwks.json

Note: Non-loopback HTTP_HOST (e.g., 0.0.0.0) without OAuth enabled is rejected at startup for security.
