Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

viridis
viridis_agent_attestation
Issue a mark-stamped agent-attestation envelope under the shared trust root.
viridis_bind_did
Derive the canonical did:viridis identity for an agent (fleet R1 formula) under the shared root.
viridis_certify
Certify a subject (parcel/portfolio) with a module -> a certificate. Errors if the module's backing theorem is not gate-passed (BLOCKED).
viridis_certify_envelope
Certify then return a 'Certified by ViridisOS' mark envelope (profile conservation-claim).
viridis_compute_toll
Compute the unified Viridis protocol margin (the take) + pass-through card cost for a settlement.
viridis_list_modules
List ViridisOS modules and their LIVE/BLOCKED state (A-1 against the live canon).
viridis_verify_mark
Verify a 'Certified by ViridisOS' envelope against the shared trust root.

Viridisos — questions

Answers built from our own checks of this server.

What can Viridisos do?
It exposes 7 tools, read directly from the server on our last check. Among them: viridis_agent_attestation, viridis_bind_did, viridis_certify, viridis_certify_envelope, viridis_compute_toll, viridis_list_modules and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Viridisos working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 356 ms. The bar chart above shows every period we have measured.
How do I connect Viridisos?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Viridisos need an API key?
No. Viridisos completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Viridisos?
It answers our handshake in 356 ms on average, which is faster than 38% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Viridisos open source?
The code is open source: it is published under the Apache-2.0 licence, written in Python, 0 stars on GitHub and 4 open issues. The licence covers the code in the repository, not the hosted service at mcp.viridisconservation.com, which runs on its operator's own terms.
