How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability77
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 561 tokens (~93/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management7
- Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
decide_create_classifier Decide Create Classifier ~136
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.
| Name | Type | Req | Description |
|---|---|---|---|
| examples | array | yes | labelled examples: [{"text": "...", "label": "..."}, ...] |
| instructions | string | – | what the labels mean (used only by a general-model fallback) |
| name | string | yes | a name for the classifier |
| threshold | number | – | confidence under which a result is flagged unsure (default 0.5) |
No output schema declared.
No examples provided.
decide_predict Decide Predict ~110
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.
| Name | Type | Req | Description |
|---|---|---|---|
| classifier_id | string | yes | classifier id, e.g. dc_4c612ec44c794df5bd82 |
| text | string | – | a single text to label |
| texts | array | – | texts to label |
No output schema declared.
No examples provided.
get_decide_classifier Get Decide Classifier ~70
Tuatara Decide: one classifier's status (queued / training / ready / failed), labels and expected accuracy on held-out examples. Poll this after creating one.
| Name | Type | Req | Description |
|---|---|---|---|
| classifier_id | string | yes | classifier id, e.g. dc_4c612ec44c794df5bd82 |
No output schema declared.
No examples provided.
get_decide_info Get Decide Info ~46
Tuatara Decide: what it is, the NEXUS plan allowances (classifiers and decisions a week), limits and the public benchmark evidence. Read-only, no auth.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_decide_classifiers List Decide Classifiers ~29
Tuatara Decide: your classifiers, your plan and its classifier limit and weekly decisions.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
register_agent Register Agent ~170
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>"}.
| Name | Type | Req | Description |
|---|---|---|---|
| contact_email | string | yes | Your owner's email |
| intended_use | string | yes | What you plan to do, e.g. 'investment for my owner' |
| name | string | yes | Your agent's name |
| via | string | – | Optional: your client (chatgpt, claude, muse, …) |
No output schema declared.
No examples provided.
How do I install the Tuatara Decide MCP server?
Tuatara Decide is a hosted endpoint at https://cymetica.com/mcp/v1/decide, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Tuatara Decide MCP server?
Tuatara Decide is an MCP server listed in the public MCP registry as com.cymetica/tuatara-decide. Train a text classifier from your labelled examples in a minute; label texts with probabilities. This page covers its hosted endpoint (https://cymetica.com/mcp/v1/decide).
Is the Tuatara Decide MCP server safe to use?
Tuatara Decide scores 73 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Tuatara Decide MCP server expose?
Tuatara Decide exposes 6 tools: register_agent, get_decide_info, list_decide_classifiers, get_decide_classifier, decide_create_classifier, decide_predict. Their descriptions and schemas cost roughly 561 tokens of context every time the server is loaded.
Does the Tuatara Decide MCP server require authentication?
No. We connected to Tuatara Decide without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Tuatara Decide MCP server still maintained?
Tuatara Decide is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
