Clarigrid vs Energy Charts
A side-by-side look at the Clarigrid and Energy Charts MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Clarigrid for environment & nature work as a local process; choose Energy Charts for environment & nature as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Clarigrid when
- You need dedicated capabilities in the Environment & Nature domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
CLARIGRID_API_KEY, ENTSOE_API_KEY, TENNET_API_KEY.
Choose Energy Charts when
- You need dedicated capabilities in the Environment & Nature domain.
- You prefer a local stdio subprocess transport.
- You want tools like
generation_mix, public_power, electricity_price.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Clarigrid has no declared pricing — check the project's own site. Energy Charts has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add clarigrid and energy-charts as separate keys in the same mcpServers object, and your assistant will call tools from either one.
