        "SUMMARY_STACK_API_KEY": "your-api-key-here",
        "SUMMARY_STACK_OBSIDIAN_LOCAL_VAULT_ROOT_PATH": "/Users/you/Obsidian/YourVault",
        "SUMMARY_STACK_TARGET_RELATIVE_FOLDER": "03_Resources/_parking_lot"
      }
    }
  }
}

Claude Code (settings.json):

{
  "mcpServers": {
    "summary-stack-obsidian": {
      "command": "uvx",
      "args": ["--from", "summary-stack-obsidian-mcp-server", "summary-stack-obsidian-mcp"],
      "env": {
        "SUMMARY_STACK_API_URL": "https://api.summarystack.ai",
        "SUMMARY_STACK_API_KEY": "your-api-key-here",

Development

# Run the server locally
pnpm nx serve summary_stack_obsidian_mcp_server

# Test with MCP Inspector (interactive debugging)
pnpm nx inspect summary_stack_obsidian_mcp_server

# Run tests
pnpm nx test summary_stack_obsidian_mcp_server

# Run linter
pnpm nx lint summary_stack_obsidian_mcp_server

# Type check
pnpm nx typecheck summary_stack_obsidian_mcp_server

Local Development Configuration

Create a .env.local file in the project directory:

# API Configuration
SUMMARY_STACK_API_URL=http://localhost:8019
SUMMARY_STACK_API_KEY=your-local-api-key

# Obsidian Vault Configuration
SUMMARY_STACK_OBSIDIAN_LOCAL_VAULT_ROOT_PATH=/path/to/your/vault
SUMMARY_STACK_TARGET_RELATIVE_FOLDER=03_Resources/_parking_lot

The inspect target will automatically load this file.
