Available components
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 Security92
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 11252 tokens (~239/item across 47 items; 41 tools + 6 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 43 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the com.twmarketdata/tw-market-data MCP server?
com.twmarketdata/tw-market-data is a hosted endpoint at https://mcp.twmarketdata.com/mcp, 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.

No change was recorded against any check on this day. Stability & Change Management went from 90 to 93. That category is still filling its 30-day observation window: 27 days of observed history at the previous scan, 28 at this one. The score rises as the window fills, whether or not the server changes.

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 →
try_sample Try a free sample (no key) ~345
Hand an unregistered caller a short taste of an open dataset, plus where to unlock the rest. ★ WHAT AN ACCOUNTLESS CALLER GETS INSTEAD OF A BARE REFUSAL. Somebody arriving through a chat connector with no plan would otherwise meet a flat rejection, which the host model relays as "this service turned you down". ★ WHAT IS ACTUALLY FREE, STATED CONCRETELY. The reference resources read with no key at all, and the five sample tickers (2330, 2317, 2454, 0050, 2603) answer through `query_dataset` with no plan. Querying beyond those over MCP starts at the Pro plan. ★ OPEN DATASETS YIELD A FEW MARKED ROWS; PAID ONES YIELD NONE. For a paid dataset the row list is not even consulted, so no figure can escape through this path regardless of what the caller passes in. `rows_withheld` states how many were held back, because a taste that does not say it is a taste reads as the whole thing. ★ NOT `query_dataset`. That one serves entitled callers in full. This exists only for the moment somebody hits the edge of what they are entitled to. ⚠️ Withdrawn datasets stay refused here too — a licence ruling is not a tier, so no amount of signing up unlocks them. Args: dataset, keyless_eligible, rows.
| Name | Type | Req | Description |
|---|---|---|---|
| dataset | string | yes | – |
| keyless_eligible | boolean | – | – |
| rows | – | – | – |

Yes. com.twmarketdata/tw-market-data asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
