Anlyon alternative
3 of these tools change something. Run those as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Changes things 3Claude Code: ask
decide_create_classifierTuatara Decide: train a text classifier from labelled examples (at least 2 per label, up to 255 labels).No findings
Why it is in this group
- The name "decide_create_classifier" says "create": a word for a change.
Description, as the server wrote it 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.
Annotations the server declares
- title: Decide Create Classifier
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: false
decide_predictTuatara Decide: label up to 256 texts with a ready classifier.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it 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.
Annotations the server declares
- title: Decide Predict
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: false
register_agentRegister this agent and get its API key — the same as POST https://cymetica.com/mcp/v1/register, no key needed.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it 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>"}.

Why it is in this group
- The name "get_decide_classifier" says "get": a word for reading.
Description, as the server wrote it Tuatara Decide: one classifier's status (queued / training / ready / failed), labels and expected accuracy on held-out examples. Poll this after creating one.

Why it is in this group

Why it is in this group
- The name "list_decide_classifiers" says "list": a word for reading.
Description, as the server wrote it Tuatara Decide: your classifiers, your plan and its classifier limit and weekly decisions.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History
Changes to its tool definitions and to its remote endpoint, newest first.
No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

"permissions": {
"allow": [

}Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as tuatara-decide. Review it before you use it.
Pin
Keep the decision: fail CI when the tools change, follow every change, or show a badge.
Pin in CI
Fail a build when the tools you reviewed are not the tools the server serves today.
