Carbon vs Hindsight
A side-by-side look at the Carbon and Hindsight MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Carbon for industrial & iot work over a hosted endpoint; choose Hindsight for knowledge & memory as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Carbon when
- You need dedicated capabilities in the Industrial & IoT domain.
- You prefer a remote HTTP/SSE transport.
- You have the keys it needs:
CARBON_API_KEY.
Choose Hindsight when
- You need dedicated capabilities in the Knowledge & Memory domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
HINDSIGHT_API_LLM_API_KEY.

Frequently asked questions
Carbon is categorized under Industrial & IoT and uses a remote HTTP/SSE transport. Hindsight belongs to Knowledge & Memory and uses a local stdio subprocess. Pick Carbon for industrial & iot work and Hindsight for knowledge & memory.
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.
Carbon is listed as free. Hindsight is listed as free. Auth: api key required. 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 carbon-2 and vectorize-io-hindsight as separate keys in the same mcpServers object, and your assistant will call tools from either one.
