Nothing serious here today

Today is the operative word: we check UND Assay every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 8

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

before
check_before_install
Evidence summary for an MCP server before you install or connect it: publisher identity level, provenance, known vulnerabilities, install scripts, maintenance, open warnings, checks that could not run, and recent changes. No warnings is NOT a safety guarantee.
changes
get_changes
Metadata changes between consecutive published versions: new network hosts, replaced or added artifact sources, newly requested credentials.
evidence
get_evidence
A single assertion of a tool (by field name) with the evidence records behind it: URL, fetch time, SHA-256.
publisher
get_publisher
How a publisher is identified across ecosystems (MCP namespace, domain, GitHub, packages) and the state of each link.
resolve
resolve_identifier
Resolve an MCP server name, catalog id or GitHub repository URL to the real registry entry. If there is no exact match, returns the closest real names so look-alikes and invented names can be caught. No account needed.
setup
get_setup
One stable answer (schema_version 1) for connecting an MCP server: its validated remote URL and transport, packages, copy-paste setup for Claude Code and JSON configs, warnings by severity, checks that could not run, and contradicted claims. auth is null until Assay has checked the sign-in metadata of the server. Never a safety rating.
tool
get_tool
Every assertion for a tool with its state (VERIFIED, CLAIMED, CONTRADICTED, STALE, UNKNOWN), reason, check and evidence records.
tools
search_tools
Search cataloged MCP servers by keywords. Returns classification (verified_publisher = the publisher proved control of a domain or verified GitHub org, NOT that a company named in the tool made it / community / not_analyzed), identity level and warning counts.

UND Assay — questions

Answers built from our own checks of this server.

What can UND Assay do?
It exposes 8 tools, read directly from the server on our last check. Among them: check_before_install, get_changes, get_evidence, get_publisher, get_setup, get_tool and 2 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 UND Assay working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 48 of 48 checks got a reply (100.0%), average response time 185 ms. The bar chart above shows every period we have measured.
How do I connect UND Assay?
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 UND Assay need an API key?
No. UND Assay completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is UND Assay?
It answers our handshake in 185 ms on average, which is faster than 74% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
