Connect

Connect źlab to your AI assistant

One URL. Your assistant gains a governed screen for material decisions about physical assets.

The connector URL

https://mcp.zircular.io/mcp

źlab is a remote MCP server (streamable HTTP, OAuth sign-in), listed in the official MCP registry as io.zircular/zlab-stress-test. Works with any MCP-capable host. Sign-in is required on first use; every analysis run asks for your authorization before consulting public data sources.

Claude (web and desktop)

Settings → Connectors → Add custom connector.
Paste https://mcp.zircular.io/mcp, then complete the sign-in when prompted.
Available on Claude Pro and Max plans.

Claude Code

Run once in your terminal:

claude mcp add --transport http zlab https://mcp.zircular.io/mcp

Cursor

Add to ~/.cursor/mcp.json:

{ "mcpServers": { "zlab": { "url": "https://mcp.zircular.io/mcp" } } }

VS Code

Add to your MCP configuration (mcp.json):

{ "servers": { "zlab": { "type": "http", "url": "https://mcp.zircular.io/mcp" } } }

Codex (CLI)

Add źlab to ~/.codex/config.toml:

[mcp_servers.zlab]
url = "https://mcp.zircular.io/mcp"

Codex handles the OAuth sign-in for you; run /mcp inside a session to confirm źlab is connected.

What your assistant gets

A governed screen for decisions that are about to move capital on physical assets — facility retrofits, equipment replacement, energy projects, vendor savings claims. źlab reads the decision case your assistant assembles and returns what the evidence currently supports, what could change the next action, and the justified posture: advance, condition, compare, measure, defer, or stop.

It does not produce a yes/no verdict, and it withholds financial magnitudes until site-level evidence supports them. When it refuses, the refusal names what is missing and how to lift it — that answer is the product working, not failing. Your assistant can gather the named evidence and resubmit the same case to raise the ceiling.

What leaves your machine, what we store, and what we never log: privacy policy.
