What your AI can do with classifier.dev
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “classify_texts”: Sort up to 1,000 texts into exactly one of your own labels each, with confidence per answer. Use this when you have many items to triage, ro.”
“Use “classify_dimensions”: Classify each text by several named dimensions, such as team, urgency and kind, in one request. Returns a label, confidence, scores and mode.”
“Use “classify_multi_label”: Like classify_texts, but each text gets every label that applies (possibly none), with an independent 0-1 score per label. Use this for tagg.”
“Use “count_labels”: Classify up to 1,000 texts and return only a histogram: how many landed on each label, and how many the model was unsure about. Use this whe.”
How secure is the classifier.dev MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how classifier.dev holds up.
Official endpoint
Operated by classifier.dev (classifier.dev) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If classifier.dev adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick classifier.dev
Choose classifier.dev in the gate directory. No sign-in needed.
Use it anywhere
classifier.dev's tools are live in every AI client you've connected — with rules and logging built in.

The actual tools classifier.dev exposes
Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
classify_texts — Sort up to 1,000 texts into exactly one of your own labels each, with confidence per answer. Use this when you have many items to triage, ro
classify_dimensions — Classify each text by several named dimensions, such as team, urgency and kind, in one request. Returns a label, confidence, scores and mode
classify_multi_label — Like classify_texts, but each text gets every label that applies (possibly none), with an independent 0-1 score per label. Use this for tagg
count_labels — Classify up to 1,000 texts and return only a histogram: how many landed on each label, and how many the model was unsure about. Use this whe
review_uncertain — Classify up to 1,000 texts and return only the ones whose confidence fell under a threshold (default 0.7), each with its two most likely lab

https://classifier.dev/mcpQuestions, answered
Is there an official classifier.dev MCP server?
Yes — classifier.dev operates its own remote MCP server at classifier.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect classifier.dev to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick classifier.dev in the directory. No account or sign-in is needed. From then on, classifier.dev's tools are available in every client you've connected to gate.
Do I need to host anything?
No. classifier.dev runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the classifier.dev MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect classifier.dev in minutes. No credit card required.
Connect more than just classifier.dev
Every server below works through the same gateway URL — connect once, add tools anytime.
