What it can do

Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.

  • list_plans

    List the versioned monthly-seat catalog, exact prices/coverage, catalog SHA-256, readiness flags, and pending owner-confirmation notice.

  • get_plan

    Get one exact monthly plan and its versioned catalog lineage.

  • create_account

    Create a free account for bearer attribution. The full account key is returned once; only its SHA-256 and last four characters are retained.

  • create_checkout_link

    Prepare a Stripe-hosted subscription Checkout URL. It never charges a card. Draft plans, missing owner approval, unavailable covered agents, or missing recurring Price IDs fail closed without creating a session.

  • record_subscription

    Pull-verify a Stripe session/subscription and idempotently activate its exact subscription period. A newly created account receives its key once.

  • subscription_status

    Return bearer-owned subscription lifecycle and current-period quota. The account key is always masked in output.

  • customer_portal_link

    Return a bearer-owned Stripe-hosted billing-portal URL. The human manages or cancels there; this tool never moves money.

  • usage_summary

    Return bearer-owned, period-resolved included and overage usage with exact catalog lineage and conservation totals.

  • mrr_summary

    Return aggregate active live-mode subscription count, MRR minor units, and plan mix. No account or Stripe identifiers are exposed.

  • describe_agent

    Return the fleet-standard version, catalog digest, security posture, lifecycle policy, and capabilities.

Common questions

Is Subscriptions safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (0.1.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

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.

Registry servers with their own docs

Each registered MCP server has a README with its tools, inputs and outputs, an example, client config and pricing:

Registry nameRemote endpointDocs
io.github.jdhart81/security-preflighthttps://mcp.viridis-security.com/security-preflight/mcpsecurity-preflight-agent/README.md

Connecting any hosted server (Claude, ChatGPT, VS Code, APIs), payments and ownership: docs/HOSTED_MCP.md.

For agents

Agents and LLM tools can start from llms.txt, a generated index of every agent, and AGENTS.md, the rules for using and changing the fleet.

Part of the Viridis open-source commons

Building agents for conservation or energy work? VergeCommon and EnergyAI MCP also expose MCP tools, and ViridisOS serves its decision functions to agents over MCP.

This project is one of a connected set of open tools from Viridis. Each stands on its own; together they run from field evidence to checked decisions.

Conservation commons

Verifiable science

  • Viridis Canon: machine-checked Lean 4 mathematics for ecological decisions, with a DOI for every result
  • ViridisOS: open reference runtime for DOI-backed decision modules and recomputable results
  • Viridis Research: the nightly public research record, each claim labeled by what a verifier actually checked
  • ProofLens: see what a Lean statement means before reading the proof

Agent tools

  • Viridis Agent Fleet (this repository): open-source MCP agents with deterministic, auditable cores
  • EnergyAI MCP: energy-planning estimates and incentive sources for AI agents

Browse every project on the Viridis profile. If this one is useful to you, a star helps other people find it.

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.
