Security Report
4.8
Use Caution4.8High RiskThis is a well-architected MCP gateway server for a multi-agent economy platform. The code is clean, follows good practices for dynamic module loading with proper isolation, and uses standard frameworks (Starlette, uvicorn) securely. The main security posture is deliberately open in Round 1 (reads-only, no funds move), with auth/allowlist planned for later rounds. Permissions are appropriate for the stated purpose of hosting 13 agent MCP servers. Supply chain analysis found 8 known vulnerabilities in dependencies (0 critical, 5 high severity).

Viridis Agent Fleet — MCP Surface
The public MCP-facing surface of the Viridis agent stable: a 13-agent
agent-to-agent (A2A) economy published on the Model Context Protocol
registry under the earth.viridis
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.
By Viridis LLC — conservation technology.
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 |
| 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 |
| Enabler | narrative-engine | Grant / investor / policy narrative generation |

Calling an agent
Every agent is a streamable-HTTP MCP server hosted behind
https://mcp.viridis.earth/<path>/mcp (paths in each server.json). Point any
MCP client at the URL, or discover them on the registry by searching
earth.viridis. Each tools.json is the exact tool surface — one tool per
agent action, with typed input/output schemas.
Status
LIVE (2026-07-09). All 13 published on the MCP registry under
io.github.jdhart81/* and hosted at https://viridis-agent-stable.fly.dev
(/healthz = 13 ok). 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).
Round-1 posture: endpoints are open (read-tool posture); no funds move — escrow,
offsets, and metering are state machines, with payment rails (x402 for A2A,
Stripe for human-facing services) attaching in a later round. See
docs/A2A_ECONOMY.md.
