Nothing serious here today

Today is the operative word: we check Frontier Reference 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 7

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

company
get_company
Profile of a frontier company: what they build, why it matters for frontier design, competitors and technologies from the knowledge graph.
compare
compare_formats
Compare two file formats (by slug, extension, or filename) — extensions, category, and a verdict on when to choose each. Use for 'X vs Y' / 'difference between X and Y'.
convert
convert_file
Find the in-browser converter (if any) that turns one format into another, e.g. from='fbx' to='glb'. Returns the tool URL and notes, all client-side (files never upload). Use for 'how do I convert X to Y'.
definition
get_definition
Get the definition and reference copy for a dictionary term, technology, sensor, or file format by slug (use `search` to find slugs).
design
list_design_jobs
Latest design/UX/HMI roles at frontier companies (defense, robotics, space, industrial, health), refreshed from company job boards.
identify
identify_format
Identify a file format from an extension, filename, or slug (e.g. 'step', 'scan.mcap', 'gltf') and get how to open or convert it: what it stores, its extensions/MIME/spec, whether a free in-browser viewer exists, and available client-side conversions. Use for 'what is this file' / 'how do I open X'.
search
search
Full-text search across Falcon's frontier design reference: terms, technologies, file formats, sensors, companies, tools, standards.

Frontier Reference — questions

Answers built from our own checks of this server.

What can Frontier Reference do?
It exposes 7 tools, read directly from the server on our last check. Among them: compare_formats, convert_file, get_company, get_definition, identify_format, list_design_jobs 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 Frontier Reference working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 89 checks got a reply (100.0%), average response time 368 ms. The bar chart above shows every period we have measured.
How do I connect Frontier Reference?
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 Frontier Reference need an API key?
No. Frontier Reference 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 Frontier Reference?
It answers our handshake in 368 ms on average, which is faster than 35% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
