Viridis Agent Fleet

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.

Priced agents include 10 free calls/day; the settlement rails are free forever. More worked examples (Python client included): docs/QUICKSTART_FIRST_CALL.md. New: 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.
