Green Router tools (6)
write = sends, deletes, buys or postscertifyFreePAID ($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_agentFreeReturn capabilities and input contract.
green_routeFreeFREE: 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_certificatesFreeFREE: the certificate ledger — counts, total grams retired, total clearinghouse cost (honest books, GR8).
quote_footprintFreeFREE: 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_green_certificateFreeFREE 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.

What the publisher says
From the Green Router repository's README, as published. We do not edit it. Read it on GitHub
Viridis Agent Fleet: open-source agents for the agent economy
Deterministic, auditable MCP agents: trust and settlement rails (identity, trust, escrow, metering, arbitration, notary, surety, provenance, covenant, offsets, compute-ledger) and priced-grade services (tax credits, GHG accounting, construction takeoff, measurement, compliance). Every core is pure Python with no LLM in the serving path, and every result is content-addressed so anyone can re-verify it.
Licensed Apache-2.0. Run any agent yourself, fork it, embed it.
Run an agent locally (free, forever)
pip install -r requirements-dev.txt
python3 agent-escrow-agent/adapters/mcp_server.py # stdio MCP
python3 run_fleet_tests.py # every agent's invariant testsOr use the hosted fleet
https://mcp.viridisconservation.com runs all agents as one managed MCP service:
Free tier: 10 calls/day per service; the rails (identity, escrow, metering…) are free forever. Verification is always free.
Boundary
This repo contains agent cores, MCP adapters, tests, standards and self-host tooling. The hosted service layer (gateway, payment and settlement, seats, signing authority, operations, telemetry and customer data) is proprietary and is not in this repo. Please don't open PRs that add it.
