Security Report

3.2

Use Caution3.2High Risk

This MCP gateway server dynamically loads 13 agent modules from the filesystem and hosts them over HTTP with disabled DNS rebinding protection and permissive CORS. While the core gateway code is well-structured, critical security concerns include: (1) disabled transport security with wildcard allowed hosts/origins, (2) dynamic module loading with minimal isolation between agent cores, (3) no authentication or authorization on any endpoints, and (4) reliance on external agent code without sandboxing. The server appears to be in early deployment ("round 1") with acknowledged gaps in authentication and payment rails. Supply chain analysis found 8 known vulnerabilities in dependencies (0 critical, 5 high severity).

Viridis Agent Fleet: open-source agents for the agent economy

Deterministic, auditable MCP agents: trust and settlement rails (identity, trust, escrow, metering, arbitration, notary, surety, provenance, covenant, offsets, compute-ledger) and priced-grade services (tax credits, GHG accounting, construction takeoff, measurement, compliance). Every core is pure Python with no LLM in the serving path, and every result is content-addressed so anyone can re-verify it.

Licensed Apache-2.0. Run any agent yourself, fork it, embed it.

Run an agent locally (free, forever)

pip install -r requirements-dev.txt
python3 agent-escrow-agent/adapters/mcp_server.py          # stdio MCP
python3 run_fleet_tests.py                                 # every agent's invariant tests

Or use the hosted fleet

https://mcp.viridisconservation.com runs all agents as one managed MCP service:

	Self-hosted (this repo)	Hosted by Viridis
Agent logic & verification	✅ identical	✅ identical
Viridis-signed receipts & notary chain	–	✅
Shared trust/reputation network data	–	✅
Maintained rule packs (tax, GHG factors, regs)	snapshot	✅ kept current
Payments (x402, card), seats, SLA	–	✅

Free tier: 10 calls/day per service; the rails (identity, escrow, metering…) are free forever. Verification is always free.

Boundary

This repo contains agent cores, MCP adapters, tests, standards and self-host tooling. The hosted service layer (gateway, payment and settlement, seats, signing authority, operations, telemetry and customer data) is proprietary and is not in this repo. Please don't open PRs that add it.
