You need both the provider selection and its API key: ```bash # Choose ONE provider and set BOTH values # Option A: Anthropic OPENCODE_PROVIDER=anthropic ANTHROPIC_API_KEY=sk-ant-api03-... # Option B: OpenAI # OPENCODE_PROVIDER=openai # OPENAI_API_KEY=sk-... # Option C: Google # OPENCODE_PROVIDER=google # GOOGLE_GENERATIVE_AI_API_KEY=AIza... ``` ### Step 2: Configure MCP Server The MCP server authenticates requests using an Open Mercato API key: 1. Log into Open Mercato backend 2. Go to **Settings > API Keys** 3. Create a new API key with appropriate permissions 4. Copy the key (starts with `omk_`) and add it to `.env`: ```bash # .env MCP_SERVER_API_KEY=omk_your_api_key_here ``` ### Step 3: Create .mcp.json for Claude Code Integration (Optional) If you want to use Claude Code with your MCP server, create `.mcp.json` in the project root: ```json { "mcpServers": { "open-mercato": { "type": "http", "url": "http://localhost:3001/mcp", "headers": { "x-api-key": "omk_your_api_key_here" } } } } ``` The `x-api-key` should be an Open Mercato API key created in the backend admin (Settings > API Keys). ### Step 4: Start Services The default hybrid dev mode needs just two commands — `yarn infra:up` starts OpenCode plus the infrastructure containers, and `yarn dev` runs the app **and** the MCP server on the host (provisioning the MCP API key into `.mercato/mcp-shared/mcp-api-key` automatically): ```bash yarn infra:up yarn dev ``` To run the pieces individually instead: ```bash # Terminal 1: Start MCP development server yarn mcp:dev # Terminal 2: Start OpenCode container docker compose --project-directory . -f starters/docker/compose.infra.yml up -d opencode # Terminal 3: Start Next.js app yarn dev ``` ```` First 4,000 characters.
