MealCP MCP

Official Model Context Protocol server for MealCP — the grocery & food data layer for AI agents.

Exposes two tools over the MealCP public API:

• search_products — search the grocery product catalog by keyword with faceted filtering (country, retailer, chain, brand, tag, category, city, price range, sort, pagination).
• get_price_history — aggregated price-history stats (min/max/avg/first/ last, net change) for one product over a date range.

Requirements

• Python 3.10+
• An API key from MealCP (each tool call consumes 1 credit)

Usage

Run directly with uv:

uvx mealcp-mcp

Or install:

pip install mealcp-mcp
mealcp-mcp

The server speaks MCP over stdio; any MCP host (Claude Desktop, opencode, Cursor, …) can spawn it.

Claude Desktop

{
  "mcpServers": {
    "mealcp": {
      "command": "uvx",
      "args": ["mealcp-mcp"],
      "env": {
        "MEALCP_API_URL": "https://api.mealcp.com",
        "MEALCP_API_KEY": "mcp_live_your_key_here"
      }
    }
  }
}

opencode

    "mealcp": {
      "type": "local",
      "command": ["uvx", "mealcp-mcp"],
      "enabled": true,
      "environment": {
        "MEALCP_API_URL": "https://api.mealcp.com",

}

Configuration

Variable	Default	Description
MEALCP_API_URL	http://localhost:8000	Base URL of the MealCP API
MEALCP_API_KEY	(none)	X-API-Key sent with every request

Errors

Tool errors surface the API's stable error tokens, formatted <code>: <message> (e.g. not_found: Product not found). Branch on the code, never the message.

Contract

Response models are generated from the API's OpenAPI spec (contract/openapi.json, currently version 0.1.0). Refresh with:

uvx --from datamodel-code-generator datamodel-codegen \
  --input contract/openapi.json \
  --output src/mealcp_mcp/models.py \
  --output-model-type pydantic_v2.BaseModel \
  --target-python-version 3.10 --disable-timestamp

Development

uv sync
uv run pytest
uv run ruff check .
