MCP tools · 41 exposed · ~11,424 tokens

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 →

Tool Tokens
search_filings ~675

Semantic search over MOPS filings and announcements — ⚠️ NOT YET AVAILABLE (語意檢索尚未提供/建置中). ★ STATUS, READ FIRST: the semantic index has not been built. Every call currently returns NO rows, with `corpus.index_is_empty: true` and `corpus.service_status: "not_yet_available"`. Tell the user this capability is not available yet. Do NOT present it as a working feature, and do NOT read the empty result as "the company disclosed nothing" — it is a service state, not a fact about any company. Once built, it matches on MEANING rather than keywords. The declared corpus is MOPS 重大訊息 subject lines plus a small MOPS full-text set; financial-statement notes do not exist in this database and company news is refused — `corpus` in every response says exactly what is indexed. ★ POINT-IN-TIME: pass `as_of` (YYYY-MM-DD). Chunks are filtered `published_at <= as_of` in SQL BEFORE ranking, so a backtest cannot retrieve a filing that did not exist yet. `meta.as_of_applied` echoes the cutoff that actually ran — check it. **Without `as_of` the results include the most recent filings and are look-ahead UNSAFE for backtesting**; the response says so in `meta.warnings`. ★ REFERENCE CONTEXT, NOT AUTHORITY. Every hit carries `source`, `source_tier` ("official" = MOPS/exchange, "third_party" = press) and a `url`. Read the chunk and judge it yourself; the ranking is similarity, not importance, and similarity is not evidence. **Nothing here is investment advice** (`not_investment_advice: true`). ★ A ticker you asked about that returns nothing appears in `coverage.missing` with a reason. That means NOTHING IS INDEXED for it under those filters — it does NOT mean the company disclosed nothing. Do not fill the gap. Args: query: what to look for, in Chinese or English (e.g. '匯率風險', 'CoWoS capacity'). tickers: restrict to these codes, e.g. ['2330','2317']. doc_type: 'mops_major_event' or 'mops_a…

set_price_alert ~255

Leave a standing instruction: tell me when this symbol crosses this price. The alert OUTLIVES this conversation. It is evaluated against official daily closes by a resident agent and delivered to your realtime stream and to any webhook endpoints you have registered — signed, retried, and de-duplicated so one crossing is one notification. This is a NOTIFICATION, not an order. Nothing in TWMD can place a trade. Args: rule_id: your name for this alert. Re-using one UPDATES it rather than adding a second. symbol: the Taiwan ticker, e.g. "2330". direction: "below" or "above". threshold: the price level, in TWD. label: optional human-readable note carried on the alert. edge_triggered: True (default) fires on the CROSSING only — one long slump does not notify you every day. False fires on every bar that is past the level.

supply_chain_read ~279

供應鏈與同業:產業鏈位置、同業分組、轉投資、外銷訂單 vs 營收。 ★ 事實整理,不是投資建議、不是預測。輸出帶 `does_not_prove`。 ★ ⚠️ `company_peer_groups` 無日期欄:指定過去的 `as_of` 時,回的是**現況**分組, `pit_notes` 會標「非當時分類」。 ★ ⚠️ 質化的客戶/供應商關係與分部營收在年報附註,那條來源**尚未建置** —— 固定列在 `cannot_see`(status=no_loader),不是這次查失敗。 ★ Args:`ticker`(例如 "2330")、`as_of`(選填)。 ★ Returns:誠實信封;外銷訂單與營收的背離會 listed in `concerns`。 ★ PRECONDITIONS:自己取數;requires 一個已識別的 session。 ★ SIDE EFFECTS:read-only,does not 寫入。

try_sample ~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.

Install

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.

Common questions

What is the com.twmarketdata/tw-market-data MCP server?

com.twmarketdata/tw-market-data is an MCP server listed in the public MCP registry as com.twmarketdata/tw-market-data. Taiwan stock market data (TWMD): official-source, point-in-time-safe datasets via read-only tools. This page covers its hosted endpoint (https://mcp.twmarketdata.com/mcp).

Is the com.twmarketdata/tw-market-data MCP server safe to use?

com.twmarketdata/tw-market-data scores 89 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 com.twmarketdata/tw-market-data MCP server expose?

com.twmarketdata/tw-market-data exposes 41 tools: list_datasets, describe_dataset, query_dataset, find_related, search_filings, and 36 more. Their descriptions and schemas cost roughly 11,424 tokens of context every time the server is loaded.

Does the com.twmarketdata/tw-market-data MCP server require authentication?

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.

Is the com.twmarketdata/tw-market-data MCP server still maintained?

com.twmarketdata/tw-market-data 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 com.twmarketdata/tw-market-data MCP server?

VerifyMCP ran 13 checks on com.twmarketdata/tw-market-data, 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.
