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.

    child = subprocess.Popen(cmd, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
Page executes code built at runtime products/signed-cliff-check/verify.html:177
  $("cta").innerHTML = renderCta(PAYMENT_LINK_URL);

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 4

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

build
build_brain
Compile an agent file into a deterministic, content-addressed brain. content = the file as a string; format = verdigraph_genome | claude_project_export | openai_assistant | prompt_list | auto. Returns brain_id, content_hash, node/edge counts, the 9-invariant firing report, and provenance. Identical bytes always produce the identical brain_id (VB1). include_document=true returns the full graph.
describe
describe_agent
Return capabilities and input contract.
detect
detect_format
Detect which supported agent-file format the content is (verdigraph_genome, claude_project_export, openai_assistant, prompt_list) before building.
verify
verify_brain
Machine-check a cognition claim: recompute the brain from the submitted content and compare against the claimed brain_id and/or content_hash. valid=true iff every claimed identifier matches the deterministic recomputation (VB3).

Verdigraph — questions

Answers built from our own checks of this server.

What can Verdigraph do?
It exposes 4 tools, read directly from the server on our last check. Among them: build_brain, describe_agent, detect_format, verify_brain. 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 Verdigraph 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 365 ms. The bar chart above shows every period we have measured.
How do I connect Verdigraph?
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 Verdigraph need an API key?
No. Verdigraph completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Verdigraph?
It answers our handshake in 365 ms on average, which is faster than 37% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Verdigraph 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.
