Viridis Agent Fleet — MCP Surface

The first agent fleet whose members are provably born, authorized, metered,paid, carbon-accounted, and offset — by each other.Read the receipts. Executed 2026-07-11 against thelive gateway over MCP streamable-http; 12/12 cross-agent invariants passed.The rails it ran on are live at the same endpoint, free to call.

The public MCP-facing surface of the Viridis agent stable: a 13-agentagent-to-agent (A2A) economy published on the Model Context Protocolregistry under theio.github.jdhart81 namespace. This repository is the callable spec +provenance for those listings — the registry manifests, the JSON-Schema tooldefinitions, the public agent contracts, and the reference gateway. The agentcores are maintained privately; everything here is what a calling agent needs.

By Viridis LLC — conservation technology.

The economy: identity → trust → escrow → settlement → constitution

Trustworthy agents transacting with agents needs rails. This fleet ships themas composable MCP services:

Layer	Agent	Endpoint	What it provides
Identity	`agent-identity-registry`	`/identity/mcp`	Content-addressed agent DIDs + capability discovery — the passport + directory
Trust	`agent-trust-oracle`	`/trust/mcp`	Decay-weighted reputation + tamper-evident trust attestations
Settlement	`agent-escrow`	`/escrow/mcp`	Trustless escrow with an exactly-once state machine + audit hash chain
Metering	`agent-metering`	`/metering/mcp`	Usage metering + SLA accounting — the meter behind x402
Arbitration	`agent-arbitration`	`/arbitration/mcp`	Dispute-resolution oracle consuming trust signals
Compute ledger	`agent-compute-ledger`	`/compute-ledger/mcp`	"Compute is carbon" cost/energy accounting for agent work
Covenant	`agent-covenant`	`/covenant/mcp`	Deny-by-default authority leases for agents wielding real power
Provenance	`agent-provenance`	`/provenance/mcp`	Genesis certificates, lineage, cascading recalls
Offsets	`agent-offset-clearinghouse`	`/offsets/mcp`	Verified-credit carbon accountability — the conservation flywheel
Revenue	`smartscale`	`/smartscale/mcp`	Credit-card-calibrated measurement — the first sellable service
Revenue	`protogen`	`/protogen/mcp`	MCP CAD services; bundles with SmartScale (measure → CAD)
Revenue	`regulatory-radar`	`/regulatory-radar/mcp`	CSRD/TNFD compliance-as-a-service
Enabler	`narrative-engine`	`/narrative-engine/mcp`	Grant / investor / policy narrative generation

Federated member: EnergyAI — energyintelligence (solar estimates, US incentives by ZIP, Energy Node Scores) on itsown infrastructure, discoverable through this fleet's catalog.

Calling an agent

Every agent is a streamable-HTTP MCP server athttps://mcp.viridisconservation.com/<path>/mcp. Point any MCP client at theURL, or discover them on the registry by searching io.github.jdhart81.Machine-readable fleet catalog:/.well-known/ai-catalog.json ·Fleet health: /healthz.Each tools.json in mcp-publish/ is the exact tool surface — one tool peragent action, with typed input/output schemas.

Layout

mcp-publish/<agent>/server.json   # MCP registry manifest
mcp-publish/<agent>/tools.json    # JSON-Schema tool definitions (one per action)
mcp-publish/<agent>/DEPLOY.md     # env, endpoints, how a caller uses it
contracts/<agent>.md              # public agent contract (capabilities, invariants)
gateway/                          # reference gateway: one process hosts all 13 over streamable-http
docs/GENESIS_RECEIPTS.md          # the first self-transaction — live, 12/12 invariants
docs/A2A_ECONOMY.md               # the full identity→trust→escrow thesis + composition demo

Status

LIVE. All 13 published on the MCP registry under io.github.jdhart81/*,hosted at https://mcp.viridisconservation.com (13/13 healthy). Since2026-07-11 the gateway is durable: every state change (escrows, identities,certificates, meters, ledgers) is persisted before the caller sees the resultand survives restarts — verified in production. Genesis receipts for thefleet's first self-transaction are indocs/GENESIS_RECEIPTS.md.

Pricing — built for network growth

The rails are free, forever. Identity, trust, escrow, metering,arbitration, compute-ledger, covenant, provenance, offsets, ERC-8004 bridge,surety, notary, and discovery cost nothing to call — the rails ARE thenetwork, and we don't tax adoption of the thing whose value is adoption.

The two services are penetration-priced for agent budgets: smartscale$0.50/call, protogen $1.00/call — after 100 free calls per day. Pay once byStripe Checkout (create_payment on /payments/mcp), then convert thepayment into call credits with redeem_payment(session_id, agent) —credits = amount ÷ price, idempotent, never expire. A2A callers settleper-call via the x402/escrow idiom. Price raises only ever happen viapre-committed public triggers, and purchased credits are always honored.

Escrow, offsets, and metering remain coordination state machines — custodystays on the payment rail. See docs/A2A_ECONOMY.md.
