Side-by-Side Model Context Protocol Comparison
Carbon Interface vs Tldraw
In-depth architectural comparison of the Carbon Interface and Tldraw MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Carbon Interface
Developer Tools · Remote HTTP/SSE
Quality: 49/100 (Fair) | Auth: No auth required
Tldraw
Developer Tools · Local stdio
Quality: 52/100 (Good) | Auth: No auth required
Verdict Summary: Choose Carbon Interface if you need specialized Developer Tools tools running via a hosted cloud SSE transport. Choose Tldraw if your workspace requires Developer Tools integration with local subprocess execution. Both servers can be configured concurrently in your client's
mcpServers manifest.Which MCP Server Should You Choose?

Tools & Capabilities Breakdown
Carbon Interface Tools (3)
estimate_electricity
Estimate CO2 emissions from electricity usage. Returns carbon emissions in grams, kg, and metric tons. Example: estimate_electricity(500, "us", "kwh") for 500 kWh in the US.
estimate_flight
Estimate CO2 emissions from a flight. Provide number of passengers and flight legs (departure/arrival airport IATA codes). Returns per-passenger and total carbon emissions. Example: estimate_flight(2, [{"departure_airport": "SFO", "destination_airport": "JFK"}]).
estimate_vehicle
Estimate CO2 emissions from driving a vehicle. Provide distance and a vehicle model ID (from Carbon Interface). Returns carbon emissions in grams, kg, and metric tons. Example: estimate_vehicle(100, "7268a9b7-17e8-4c8d-acca-57059252afe9", "mi").
