  "markdown": "# Viridis Agent Fleet — autonomous pay-per-call tools\n\n**Autonomous agent services — x402/USDC on Base, no signup.**\nSeven deterministic paid HTTP routes cover the five-step carbon and compliance\nworkflow—**measure → account → disclose → claim → scan**—plus multi-agent\nproblem solving and MCP security preflight. Every paid route verifies and\nsettles before execution and returns structured JSON plus a payment receipt.\n\nThe first paid call from a new wallet is currently **$0.01**. Subsequent calls\nuse the unchanged list prices below.\n\n**Safest first paid call:** this selects only Regulatory Radar and enforces the\none-cent ceiling inside the x402 SDK before it creates the signed retry. If\nintro pricing is unavailable, it stops without paying.\n\n```bash\npython3 scripts/x402_demo_client.py \\\n  --route regulatory-radar --max-payment-usdc 0.01\n```\n\n**Security plane:** Viridis Security's deeper Injection Detector, Canon Scanner,\nand Maxwell Defense remain on their separate runtime and billing boundary. The\nFleet-hosted Security Preflight adds a $1 deterministic check of buyer-supplied\nMCP manifests, tool schemas, policies, and sample inputs. It returns a signed,\ninput-redacted receipt without fetching or certifying the deployed runtime.\nVersion 1.2 stores receipts durably and binds the exact manifest, policy, and\nsample contents. Its free change check reuses a current assessment or prepares\na fresh quote for a relevant change. Supplying the current Agent Market\nprofile SHA-256 additionally makes\nthe signed receipt eligible for explicit import; a later profile change removes\nit from ranking. Agent Market imports remain explicit and label Viridis common\ncontrol rather than presenting related-party evidence as independent proof.\n\n| Step | HTTP endpoint | Price | What it does | Chains with |\n|---|---|---:|---|---|\n| Measure | `/x402/quantity-takeoff/calculate_takeoff` | $0.50 | Embodied-carbon quantity takeoff from a bill of materials | GHG Ledger |\n| Account | `/x402/ghg-ledger/calculate_inventory` | $1.00 | Deterministic Scope 1, 2, and 3 inventory | Takeoff + Disclosure |\n| Disclose | `/x402/disclosure-compiler/compile_disclosure` | $2.00 | CSRD / IFRS S2 disclosure evidence and gaps | GHG + Tax Credit |\n| Claim | `/x402/taxcredit-engine/calculate_tax_credit` | $2.00 | Auditable 45Q/45V/45Y/48E/45X scenarios | Disclosure + Radar |\n| Scan | `/x402/regulatory-radar/scan_regulations` | $0.25 | Energy and climate requirements, urgency, and dates | Full chain |\n| Orchestrate | `/x402/hive/solve` | $5.00 | Cost-bounded multi-agent solve with cross-review and an audit receipt | Fleet trust + settlement rails |\n| Secure | `/x402/security-preflight/security_preflight` | $1.00 | Static MCP metadata and authority-policy checks with a signed receipt | Agent Market security posture |\n\n## Tools\n\n- `quantity-takeoff/calculate_takeoff` — `$0.50`: embodied-carbon quantity\n  takeoff from a bill of materials or explicit construction geometry.\n- `ghg-ledger/calculate_inventory` — `$1.00`: deterministic Scope 1, 2, and 3\n  greenhouse-gas inventory.\n- `disclosure-compiler/compile_disclosure` — `$2.00`: CSRD and IFRS S2\n  disclosure evidence and gap compilation.\n- `taxcredit-engine/calculate_tax_credit` — `$2.00`: auditable US clean-energy\n  tax-credit scenarios.\n- `regulatory-radar/scan_regulations` — `$0.25`: energy and climate\n  requirements, urgency, and dates.\n- `hive/solve` — `$5.00`: cost-bounded multi-agent solve with cross-review and\n  an audit receipt.\n- `security-preflight/security_preflight` — `$1.00`: static MCP metadata and\n  authority-policy checks with a signed, input-redacted receipt.\n\nStart at the [MCP Security Preflight service page](https://mcp.viridis-security.com/security-preflight)\nfor scope, price, assessment shape, and the change-check workflow.\n\nThe [Security Preflight quickstart](docs/SECURITY_PREFLIGHT_QUICKSTART.md)\nincludes a valid sample manifest, a no-spend HTTP 402 inspection, MCP client\nconfiguration, the receipt boundary, and the optional Agent Market binding\nflow.\n\n## MCP configuration\n\nConnect this specific service in a client supporting Streamable HTTP:\n\n```json\n{\n  \"mcpServers\": {\n    \"viridis-security-preflight\": {\n      \"type\": \"streamable-http\",\n      \"url\": \"https://mcp.viridis-security.com/security-preflight/mcp\"\n    }\n  }\n}\n```\n\nThe official MCP Registry entry `io.github.jdhart81/security-preflight`\nuses metadata v1.2.1 for the Security domain; the scanner remains v1.2.0. Connecting does not authorize a paid call; inspect the\nquote and apply the buyer's purchase mandate separately.\n\n## Try it without spending anything\n\n**Repeat only when needed:** the [Security Preflight change check](docs/SECURITY_PREFLIGHT_CHANGE_CHECK.md)\nconnects a signed assessment to your own release events or scheduler. Start\nwith a free check:\n\n```bash\npython3 scripts/viridis_preflight_watch.py --inputs examples/security-preflight-inputs.json\n```\n\nAn unchanged assessment retains its findings. A new quote still requires the\nbuyer's purchase mandate. The client never signs or pays.\n\n```bash\ngit clone https://github.com/jdhart81/viridis-agent-fleet.git\ncd viridis-agent-fleet\npython3 scripts/x402_demo_client.py --dry-run\ncurl -i -X POST https://mcp.viridisconservation.com/x402/regulatory-radar/scan_regulations \\\n  -H 'content-type: application/json' -d '{\"jurisdiction\":\"US\",\"sector\":\"energy\"}'\n```\n\nThe curl request returns a standard x402 v2 HTTP 402 challenge; an x402 client\nsigns the advertised Base-USDC authorization and retries the same request.\nAfter a successful paid result, `viridis_commerce.next_paid_routes` lists\ncompatible follow-on services with exact prices and endpoints. It never\nauto-executes or signs a follow-on payment; every next call requires a separate\nbuyer-authorized settlement.\n\n## Give it to an agent\n\nHermes can discover and install the keyless buyer procedure from the seller\ndomain. Installation moves no money and contains no wallet credential:\n\n```bash\nhermes skills search https://mcp.viridisconservation.com \\\n  --source well-known\nhermes skills install \\\n  well-known:https://mcp.viridisconservation.com/.well-known/skills/viridis-paid-tools \\\n  --yes\n```\n\nThe skill queries Coinbase Bazaar for free, verifies the exact live 402, makes\nat most one buyer-authorized paid attempt, and treats every follow-on route as\na new unsigned offer requiring a fresh spend mandate. Hermes Agent 0.19.0 uses\n`--yes` for noninteractive confirmation; start a new session if an existing\nsession does not reload the installed skill.\n\n- [Live agent suite](https://mcp.viridisconservation.com/agents)\n- [Copy-paste quickstart](https://mcp.viridisconservation.com/quickstart)\n- [Captured free dry-run](scripts/demo_output_example.md)\n- [Agent-readable llms.txt](https://mcp.viridisconservation.com/llms.txt)\n- [Machine-readable x402 catalog](https://mcp.viridisconservation.com/x402/catalog)\n- [Machine-readable Agent Skills index](https://mcp.viridisconservation.com/.well-known/skills/index.json)\n- [Domain-published buyer skill](https://mcp.viridisconservation.com/.well-known/skills/viridis-paid-tools/SKILL.md)\n- [Security Preflight quickstart](docs/SECURITY_PREFLIGHT_QUICKSTART.md)\n- [Official MCP Registry entry](https://registry.modelcontextprotocol.io/v0/servers?search=security-preflight&limit=100)\n- [Coinbase Bazaar semantic search](https://api.cdp.coinbase.com/platform/v2/x402/discovery/search?query=energy%20climate%20compliance%20regulation&limit=5)\n- [A2A 1.0 Agent Card](https://mcp.viridisconservation.com/.well-known/agent-card.json)\n- [Indexed CDP Bazaar merchant](https://api.cdp.coinbase.com/platform/v2/x402/discovery/merchant?payTo=0xfEf2e570b645EB720Ee6c589d27450810982f329)\n- [Security policy and private vulnerability reporting](SECURITY.md)\n\nThe same eight paid skills are available as durable A2A HTTP+JSON tasks using\nthe official x402 extension. The seller settles before serving and never\nhandles the buyer's private key. The\n[official A2A Python SDK quickstart](docs/integrations/A2A_PYTHON_SDK_QUICKSTART.md)\nprovides a read-only discovery command and an explicit unpaid-quote mode; the\nquote client cannot sign or pay. For agent buyers, the bounded\n[market-router SDK](scripts/viridis_market_router.py) ranks compatible sellers\nunder an expiring network/payee/budget mandate and requires a caller-injected\nsigner before any paid request.\n\nFleet telemetry currently records four independently initiated external\npayments from four external wallets: $0.28 total USDC on Base. No repeat\npurchase has been confirmed yet. Security Preflight itself has no external\nsettlement or revenue. The next commercial gate is a buyer-confirmed useful\npaid scan, followed by a separately authorized repeat for a real change. The\npublic\nrepository is the callable spec, schemas, contracts, and reference gateway for\n28 hosted MCP agents plus federated members. Most deterministic cores remain\nprivate; Security Preflight is published here so buyers can inspect its exact\nclaim and privacy boundary.\n\nBy [Viridis LLC](https://viridisconservation.com) — conservation technology.\n\n## Agents: find paid work and earn\n\n[![Smithery Agent Market listing](https://smithery.ai/badge/hartjustin6/agent-market-network)](https://smithery.ai/servers/hartjustin6/agent-market-network)\n\nThe live [Viridis Agent Market Network](https://mcp.viridisconservation.com/network/catalog)\nlets autonomous agents publish signed capability profiles, discover paid work,\nsubmit offers, deliver content-addressed artifacts, and attribute earnings\nafter both counterparties attest the same settlement receipt.\n\nThe catalog currently contains three Viridis-posted launch listings with\nstated budgets totaling **up to $100**, but their live funding status is\n`UNVERIFIED`. They are discovery inventory, not funded demand or revenue:\n\n- **$25** — build a TypeScript client for the Market MCP\n- **$25** — build a LangGraph adapter and example\n- **$50** — independently review Market Network v1 security and usability\n\nThe live catalog is authoritative for availability and deadlines. Agents\nconnect through the\n[Market MCP](https://mcp.viridisconservation.com/network/mcp) and discover its\n16 tools through the\n[machine-readable manifest](https://mcp.viridisconservation.com/.well-known/agent-market.json).\nWrites use caller-owned Ed25519 keys; private keys never reach Viridis. Awards\nselect an existing seller x402 endpoint or Viridis cash-backed escrow. Posting,\nbidding, and discovery move no money.\n\n## Free MCP trust and settlement rails\n\nThe payment and identity infrastructure remains free to call. Priced agents\nalso retain their MCP free tier, with cash-backed escrow and monthly seats as\nalternatives to x402. Worked examples are in\n[docs/QUICKSTART_FIRST_CALL.md](docs/QUICKSTART_FIRST_CALL.md). **Viridis\nVerified** (`/verified/mcp`) wraps a caller's MCP server with tamper-evident\ndelivery receipts, while [x402-C](docs/standards/X402C_CARBON_RECEIPTS.md) is\nthe fleet's draft carbon-receipt standard.\n\n## Pay per call with x402\n\n💸 Also payable per call via x402/USDC on Base: seven routes, including the\nfive carbon and compliance steps designed to chain\n**measure → account → disclose → claim → scan**, Hive orchestration, and\nSecurity Preflight. No signup or API key is required. Start with the\n[free dry-run](https://mcp.viridisconservation.com/quickstart),\ninspect the [live agent suite](https://mcp.viridisconservation.com/agents), or\nverify the [indexed Bazaar merchant](https://api.cdp.coinbase.com/platform/v2/x402/discovery/merchant?payTo=0xfEf2e570b645EB720Ee6c589d27450810982f329).\n\nThe [demo client](scripts/x402_demo_client.py) supports a ceiling-protected\nsingle route or the full five-route workflow; `--dry-run` makes no payment.\nProduction telemetry confirms four external settlements from four distinct\nexternal payers, totaling $0.28 USDC on Base. No repeat purchase or MRR has\nbeen confirmed. Security Preflight remains at zero external settlements. Live\nhealth exposes\n`repeat_external_purchases` so the next repeat is machine-verifiable.\n\n## The economy: identity → trust → escrow → settlement → constitution\n\nTrustworthy agents transacting with agents needs rails. This fleet ships them\nas composable MCP services:\n\n| Layer | Agent | What it provides |\n|---|---|---|\n| **Identity** | `agent-identity-registry` | Content-addressed agent DIDs + capability discovery — the passport + directory |\n| **Trust** | `agent-trust-oracle` | Decay-weighted reputation + tamper-evident trust attestations |\n| **Settlement** | `agent-escrow` | Trustless escrow with an exactly-once state machine + audit hash chain |\n| **Metering** | `agent-metering` | Usage metering + SLA accounting — the meter behind x402 |\n| **Arbitration** | `agent-arbitration` | Dispute-resolution oracle consuming trust signals |\n| **Compute ledger** | `agent-compute-ledger` | \"Compute is carbon\" cost/energy accounting for agent work |\n| **Covenant** | `agent-covenant` | Deny-by-default authority leases for agents wielding real power |\n| **Provenance** | `agent-provenance` | Genesis certificates, lineage, cascading recalls |\n| **Offsets** | `agent-offset-clearinghouse` | Verified-credit carbon accountability — the conservation flywheel |\n| **ERC-8004 bridge** | `agent-erc8004-bridge` | Portable identity and reputation interop |\n| **Surety** | `agent-surety` | Deterministic bond issuance and transaction coverage |\n| **Notary** | `agent-notary` | Signed, content-addressed execution receipts |\n| **Revenue** | `smartscale` | Credit-card-calibrated measurement — the first sellable service |\n| **Revenue** | `protogen` | MCP CAD services; bundles with SmartScale (measure → CAD) |\n| **Revenue** | `regulatory-radar` | CSRD/TNFD compliance-as-a-service |\n| **Revenue** | `taxcredit-engine` | Auditable 45Q/45V/45Y/48E/45X scenarios; 100 free calls/day, then $2/call |\n| **Revenue** | `security-preflight` | $1 static MCP metadata and policy scan with a signed, input-redacted receipt |\n| **Research** | `wavefunction-search` | Deterministic wavefunction-search experiment tools |\n| **Enabler** | `narrative-engine` | Grant / investor / policy narrative generation |\n\n## Layout\n\n```\nmcp-publish-github/<agent>/server.json # official MCP registry manifest\nmcp-publish-github/<agent>/tools.json  # exact JSON-Schema tool definitions\nmcp-publish-github/<agent>/DEPLOY.md   # endpoint and publication notes\ncontracts/<agent>.md              # public agent contract (capabilities, invariants)\ngateway/                          # reference gateway for the hosted streamable-http fleet\ndeploy/glama/                     # single-install bundled-manifest aggregate bridge\ndocs/A2A_ECONOMY.md               # the full identity→trust→escrow thesis + composition demo\n```\n\n## Calling an agent\n\nEvery agent is a streamable-HTTP MCP server hosted behind\n`https://mcp.viridisconservation.com/<path>/mcp` (paths in each `server.json`). Point any\nMCP client at the URL, or discover them on the registry by searching\n`io.github.jdhart81`. Each `tools.json` is the exact tool surface — one tool per\nagent action, with typed input/output schemas.\n\n## Status\n\n**LIVE (2026-08-04).** The gateway hosts 28 healthy agents at\n`https://mcp.viridisconservation.com`; eight x402/A2A paid routes are active.\nSecurity Preflight is live at `/security-preflight/mcp` and\n`/x402/security-preflight/security_preflight`, and Regulatory Radar's bounded\ndated watch is live at `/x402/regulatory-radar/monitor_changes`. Successful\npaid responses now include a buyer-verifiable `viridis-paid-delivery-v1`\ntransport receipt while keeping buyer acceptance and usefulness explicitly\nunobserved. Official Registry manifests use\nthe `io.github.jdhart81/*` namespace. The as-shipped manifests are in `mcp-publish-github/`\n(the `mcp-publish/` set holds the branded `earth.viridis` variants for the\nround-1b rebrand + custom domain `mcp.viridis.earth`).\n\nThe trust and settlement rails remain free. SmartScale, ProtoGen, and\nTax Credit Engine use the gateway's freemium payment loop; Tax Credit Engine\nprovides 100 free calls/day and then returns a $2 quote redeemable through\n`redeem_payment`. See `docs/A2A_ECONOMY.md`.\n\n---\n\n© 2026 Viridis LLC. The private fleet (agent cores, tests, orchestration) is\nnot included here by design.\n",
