Viridis Agent Fleet — MCP Surface
The public MCP-facing surface of the Viridis agent stable: a 22-agent
agent-to-agent (A2A) economy plus a B2B subscriptions infrastructure surface,
published on the Model Context Protocol
registry under the io.github.jdhart81
namespace. This repository is the callable spec + provenance for those
listings — the registry manifests, the JSON-Schema tool definitions, the
public agent contracts, and the reference gateway. The agent cores are
maintained privately; everything here is what a calling agent needs.

Viridis Verified (/verified/mcp) wraps your MCP server with
tamper-evident delivery receipts, and
x402-C is our draft standard for
carbon receipts on machine-to-machine payments — comments welcome via issues.
The economy: identity → trust → escrow → settlement → constitution
Trustworthy agents transacting with agents needs rails. This fleet ships them
as composable MCP services:
| Layer | Agent | What it provides |
|---|
| Identity | agent-identity-registry | Content-addressed agent DIDs + capability discovery — the passport + directory |
| Trust | agent-trust-oracle | Decay-weighted reputation + tamper-evident trust attestations |
| Settlement | agent-escrow | Trustless escrow with an exactly-once state machine + audit hash chain |
| Metering | agent-metering | Usage metering + SLA accounting — the meter behind x402 |
| Arbitration | agent-arbitration | Dispute-resolution oracle consuming trust signals |
| Compute ledger | agent-compute-ledger | "Compute is carbon" cost/energy accounting for agent work |
| Covenant | agent-covenant | Deny-by-default authority leases for agents wielding real power |
| Provenance | agent-provenance | Genesis certificates, lineage, cascading recalls |
| Offsets | agent-offset-clearinghouse | Verified-credit carbon accountability — the conservation flywheel |
| ERC-8004 bridge | agent-erc8004-bridge | Portable identity and reputation interop |
| Surety | agent-surety | Deterministic bond issuance and transaction coverage |
| Notary | agent-notary | Signed, content-addressed execution receipts |
| Revenue | smartscale | Credit-card-calibrated measurement — the first sellable service |
| Revenue | protogen | MCP CAD services; bundles with SmartScale (measure → CAD) |
| Revenue | regulatory-radar | CSRD/TNFD compliance-as-a-service |
| Revenue | taxcredit-engine | Auditable 45Q/45V/45Y/48E/45X scenarios; 100 free calls/day, then $2/call |
| Research | wavefunction-search | Deterministic wavefunction-search experiment tools |
| Enabler | narrative-engine | Grant / investor / policy narrative generation |

Calling an agent
Every agent is a streamable-HTTP MCP server hosted behind
https://mcp.viridisconservation.com/<path>/mcp (paths in each server.json). Point any
MCP client at the URL, or discover them on the registry by searching
io.github.jdhart81. Each tools.json is the exact tool surface — one tool per
agent action, with typed input/output schemas.
Status
LIVE (2026-07-12). The gateway hosts 18 healthy agents at
https://mcp.viridisconservation.com (/healthz = 18 ok). Official Registry
manifests use the io.github.jdhart81/* namespace; the newest revenue service is
io.github.jdhart81/taxcredit-engine. The as-shipped manifests are in mcp-publish-github/
(the mcp-publish/ set holds the branded earth.viridis variants for the
round-1b rebrand + custom domain mcp.viridis.earth).
The trust and settlement rails remain free. SmartScale, ProtoGen, and
Tax Credit Engine use the gateway's freemium payment loop; Tax Credit Engine
provides 100 free calls/day and then returns a $2 quote redeemable through
redeem_payment. See docs/A2A_ECONOMY.md.
