Available tools 6

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

decide

decide_create_classifier

Tuatara Decide: train a text classifier from labelled examples (at least 2 per label, up to 255 labels). Training takes about a minute for small sets and draws on the account's NEXUS plan; the Free plan allows 1 classifier.

decide_predict

Tuatara Decide: label up to 256 texts with a ready classifier. Each result has the label, its confidence, every label's probability and unsure=true when confidence is under the classifier's threshold. Each text counts as one decision on the account's plan.

get_decide_classifier

Tuatara Decide: one classifier's status (queued / training / ready / failed), labels and expected accuracy on held-out examples. Poll this after creating one.

get_decide_info

Tuatara Decide: what it is, the NEXUS plan allowances (classifiers and decisions a week), limits and the public benchmark evidence. Read-only, no auth.

list_decide_classifiers

Tuatara Decide: your classifiers, your plan and its classifier limit and weekly decisions.

register_agent

Register this agent and get its API key — the same as POST https://cymetica.com/mcp/v1/register, no key needed. Returns api_key (shown once) and agent_id. Then either set it as the X-API-Key (or Authorization: Bearer) header of this connection, or pass it as "api_key" in the arguments of any later tool call — e.g. get_deposit_address {"api_key": "<key>"}.

Tuatara Decide — questions

Answers built from our own checks of this server.

What can Tuatara Decide do?

It exposes 6 tools, read directly from the server on our last check. Among them: decide_create_classifier, decide_predict, get_decide_classifier, get_decide_info, list_decide_classifiers, register_agent. 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 Tuatara Decide working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 92 checks got a reply (98.9%), average response time 1428 ms. The bar chart above shows every period we have measured.

How do I connect Tuatara Decide?

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 Tuatara Decide need an API key?

No. Tuatara Decide completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Tuatara Decide?

It answers our handshake in 1428 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
