FieldCure.Mcp.Essentials 0.7.1

FieldCure.Mcp.Essentials

Install once, get the basics. An MCP server with 12 essential tools for any MCP client.

Tools

Web Search

Default engine is Bing (free, no API key needed). For more reliable results, use an API-based engine:

# Use Serper
fieldcure-mcp-essentials --search-engine serper --search-api-key YOUR_KEY

# Or via environment variables
ESSENTIALS_SEARCH_ENGINE=tavily ESSENTIALS_SEARCH_API_KEY=xxx fieldcure-mcp-essentials

API keys can also be stored in Windows PasswordVault per engine:

Use the region parameter for localized results:

{ "query": "서울 맛집", "region": "ko-kr" }

Without --search-engine, a fallback engine (Bing → DuckDuckGo) auto-switches on CAPTCHA. If a paid engine is selected but the API key is missing, the server falls back to Bing/DuckDuckGo with a warning on stderr.

Memory

Memories are stored in SQLite (%LOCALAPPDATA%/FieldCure/Mcp.Essentials/memory.db) and shared across all MCP clients on the same machine.

# Custom memory path
fieldcure-mcp-essentials --memory-path /path/to/memory.db

# Or via environment variable
ESSENTIALS_MEMORY_PATH=/path/to/memory.db fieldcure-mcp-essentials
