What data it sees

Do you need an account

No: the server works without sign-in

Pay your agent's entropy bill: free honest energy/carbon footprints (Landauer-grounded, assumptions stated), free carbon-ranked routing, and $0.50 certificates backed by REAL Verra-provenance offset retirement. x402-C verifiable.

Try it (copy-paste):

curl -s https://mcp.viridisconservation.com/green-router/mcp   -H 'content-type: application/json'   -H 'accept: application/json, text/event-stream'   -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"quote_footprint","arguments":{"workload":{"backend_id":"frontier_cloud","total_tokens":3000,"output_tokens":800,"calls":100}}}}'

Returns an honest energy/carbon footprint with assumptions stated. Certificates retire Verra-provenance offsets; no retirement means no certificate, and verification is free.

Pricing: $0.50/certificate after 10 free calls/day, no signup. Footprints, carbon-ranked routing, reads, and verification are free.

How to connect

How to connect green-router to Claude

The server address to paste into Claude settings:

https://green-router--hartjustin6.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect green-router to ChatGPT

The server address to paste into ChatGPT settings:

https://green-router--hartjustin6.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

How to connect green-router to Cursor

The server address to paste into Cursor settings:

https://green-router--hartjustin6.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

quote_footprintFREE: honest energy/carbon footprint for an agent workload — {backend_id? (frontier_cloud | efficient_cloud | local_small), total_tokens, output_tokens, calls?, success_score?, grid_gco2e_per_kwh?, pue?, custom_backend? {id, wh_per_1k_tokens}}. Returns joules, gCO2e, useful bits, the retirement mass a certificate would carry, every model assumption with its source, and the Landauer context (GR1/GR2).
green_routeFREE: rank compute backends by carbon for this workload — the greenest eligible path and the gCO2e saved per call. Carbon only (GR6); pair with /neurogenesis/mcp route_task for quality-floor routing.
certifyPAID ($0.50 after free tier): compute the workload footprint, then RETIRE the required verified offset mass through the fleet's own clearinghouse — Verra provenance rides into the certificate; no retirement, no certificate (GR3, fail-closed). Returns a machine-verifiable certificate anyone can check for free (GR4).
verify_green_certificateFREE forever (GR5): recompute a certificate's footprint from its stored workload, compare against the certified numbers, and surface the clearinghouse purchase_id for the independent x402-C verify_retirement check on /offsets/mcp.
list_green_certificatesFREE: the certificate ledger — counts, total grams retired, total clearinghouse cost (honest books, GR8).
