What the code does

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

green
green_route
FREE: 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.
list_green_certificates
FREE: the certificate ledger — counts, total grams retired, total clearinghouse cost (honest books, GR8).
certify
certify
PAID ($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).
describe
describe_agent
Return capabilities and input contract.
quote
quote_footprint
FREE: 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).
verify
verify_green_certificate
FREE 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.

Green Router — questions

Answers built from our own checks of this server.

What can Green Router do?
It exposes 6 tools, read directly from the server on our last check. Among them: certify, describe_agent, green_route, list_green_certificates, quote_footprint, verify_green_certificate. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Green Router working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 369 ms. The bar chart above shows every period we have measured.
How do I connect Green Router?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Green Router need an API key?
No. Green Router completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Green Router?
It answers our handshake in 369 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Green Router open source?
We cannot say either way: written in Python, 0 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
