Carbon Arc — Claude Code MCP server: what it does, how to install
Remote MCP server connecting inference, autonomous agents, and decision primitives to your assistant. It links your editor directly to Carbon Arc infrastructure.
claude mcp add --transport http mcp https://mcp.carbonarc.aiWhat Carbon Arc does
The server provides access to Carbon Arc infrastructure over Streamable HTTP at https://mcp.carbonarc.ai. It connects your coding assistant to inference tools and agent decision primitives without local runtime setup.
Authentication uses OAuth 2.0 paired with Dynamic Client Registration. Requests fail without an API token generated in your user profile. You can register an account and retrieve this key at https://app.carbonarc.co/pricing.
What it helps with
- connect Carbon Arc infrastructure to a Claude Code session
- route inference tasks through an external HTTP endpoint
- authenticate assistant requests via OAuth 2.0
- access agent decision primitives without running a local server
Example prompts for the agent
- Check the connection to the Carbon Arc endpoint at
https://mcp.carbonarc.ai - Execute an inference task using the connected Carbon Arc server
- Verify the authorization status of the Carbon Arc token
