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. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. 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 Usability75
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 243 tokens (~243/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management20
- Stability observed for 6 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 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 1 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

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

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.

stock_vectors Stock Vectors ~243
Tuatara Embed Stocks: vector embeddings of listed stock symbols and of text in one space, built for the connections a sector label does not carry — which symbols an event, theme or headline moves, including companies it never names. Send sym:TICKER (e.g. sym:AAPL) for a symbol's own vector, or any text (a headline, a theme). With similarity_to_first=true the answer ranks inputs 2..n by cosine to input 1, so 'headline + candidate symbols in, ranked basket out' is one call. 4,096 dimensions, unit length. Up to 64 inputs per call; no account needed; nothing is stored.
| Name | Type | Req | Description |
|---|---|---|---|
| encoding_format | string | – | base64 (default, float32 little-endian) or float (4,096 numbers) |
| input | array | yes | list of texts to embed: sym:TICKER for a listed symbol's own vector, anything else is embedded as text; at most 64 |
| similarity_to_first | boolean | – | also return every other input's cosine to the first input, ranked (e.g. first = the headline, the rest = candidate symbols) |
No output schema declared.

How do I install the Tuatara Embed Stocks MCP server?
Tuatara Embed Stocks is a hosted endpoint at https://cymetica.com/mcp/v1/stock-vectors, 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.

Tuatara Embed Stocks is an MCP server listed in the public MCP registry as com.cymetica/tuatara-embed-stocks. Stock-symbol vectors: which listed symbols an event, theme or headline moves, ranked in one call. This page covers its hosted endpoint (https://cymetica.com/mcp/v1/stock-vectors).
Is the Tuatara Embed Stocks MCP server safe to use?
Tuatara Embed Stocks scores 75 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 Embed Stocks MCP server expose?
Tuatara Embed Stocks exposes 1 tool: stock_vectors. Their descriptions and schemas cost roughly 243 tokens of context every time the server is loaded.
Does the Tuatara Embed Stocks MCP server require authentication?
No. We connected to Tuatara Embed Stocks without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Tuatara Embed Stocks MCP server still maintained?
Tuatara Embed Stocks is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What did VerifyMCP test on the Tuatara Embed Stocks MCP server?
VerifyMCP ran 13 checks on Tuatara Embed Stocks, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
