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.

Runs an external command src/clients.js:19
export const has = (bin) => spawnSync(process.platform === 'win32' ? 'where' : 'which', [bin]).status === 0
Builds a file path from a variable src/mcp/create.js:107
  for (const [f, s] of Object.entries(files)) fs.writeFileSync(path.join(dir, f), s)
Page executes code built at runtime site/index.html:584
  $('o-header').innerHTML = `<span class="k">x-jev-route:</span> ${model}; task=${task}; tier=${tier}`
  $('o-saving').textContent = tier === 1 ? 'A small task goes to the fast tier, which typically costs 5 to 20 times less than a frontier model.' : c.note
Reads files and sends them to the network src/mcp/check.js:121, src/mcp/create.js:91
    for (const f of fs.readdirSync(dir).filter(f => /\.(m?[jt]s|json|toml)$/.test(f)))

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.

client
get_client_setup
Returns the exact configuration that points Claude Code, Codex or Cursor at a JEV gateway. Use when a user asks how to connect a coding agent to JEV.
mcp
get_mcp_install_commands
Returns the commands that install a remote MCP server into Claude Code, Codex and Cursor, plus a one-click Cursor install link. Use when a user wants to add an MCP server URL to their agents.
model
list_model_aliases
Lists the JEV model names (jev-auto, jev-fast, …) and what each one does. Use when choosing which model name to configure.
route
route_prompt
Shows which task class and model tier JEV's jev-auto router would pick for a coding prompt. Use to explain or predict routing decisions.

Jev Guide — questions

Answers built from our own checks of this server.

What can Jev Guide do?
It exposes 4 tools, read directly from the server on our last check. Among them: get_client_setup, get_mcp_install_commands, list_model_aliases, route_prompt. 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 Jev Guide 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 121 ms. The bar chart above shows every period we have measured.
How do I connect Jev Guide?
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 Jev Guide need an API key?
No. Jev Guide 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 Jev Guide?
It answers our handshake in 121 ms on average, which is faster than 94% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Jev Guide open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at jev-guide.jevrouter.workers.dev, which runs on its operator's own terms.
