Stoky Matrix · MCP server
Company research your AI can cite.
The Matrix is Stoky's research graph of 2,600+ companies and the industries, themes and regions around them. Entries are updated as new SEC filings and financial news arrive, and every committed version is kept. Connect it to Claude, ChatGPT or your coding agent, then ask how two companies are linked, what changed on a name this week, or what the Matrix said on an earlier date. Entries carry filing and news citations where available.

Illustrative answer · October 14, 2026
How is Nvidia tied to TSMC, and has that changed recently?
Read 2 entries and the link between them
The Matrix records TSMC as a supplier to Nvidia: TSMC makes Nvidia's wafers and does its CoWoS packaging, so TSMC's capacity limits how fast Nvidia can grow. A September 12, 2026 report said Nvidia had overtaken Apple as TSMC's largest customer, and that an unnamed customer, believed to be Nvidia, grew from 11% of TSMC's revenue in 2023 to 17% in 2025.

The 15 tools
All 15 tools are read-only. Ask in plain language; your AI calls these tools for you.
Find
| Tool | What it does |
|---|---|
matrix_status | Reports how fresh the Matrix is, how many entries and links it holds, and whether semantic search is on. |
resolve_ticker | Matches a ticker or company name to its entry, and says how it matched and how sure it is. |
find_entities | Searches companies, industries, themes and regions by name, ticker or plain-language description. Up to 6 queries at once. |
Read
| Tool | What it does |
|---|---|
get_entity_tree | Lists the sections and topics in an entry, with sizes and last-updated dates, before anything is read. |
read_entity | Reads the full profile of an entry by default, or chosen sections and topics, with available citations. Up to 20 entries at once. |
get_citations | Pages through the citation records behind an entry, its links and retail discussion. Dated-fact citations cover the newest 200 facts in the window. |
get_facts | Returns dated facts for an entry, each with its source. |
Connections and sentiment
| Tool | What it does |
|---|---|
get_neighbors | Lists linked entries by strength and type. Typed links come with a stated reason; co-mention and similarity links are looser leads. Can go two steps out. |
find_path | Finds the strongest chain of links between two entries, up to 4 steps, with the reason at each step. |
get_sentiment | Returns retail discussion: stance, confidence, attention level, 7-day changes and the main threads. Says so when there is none. |
get_market_pulse | Lists entries updated in a recent window (1 hour to 30 days) and names with unusual retail attention. |
History
| Tool | What it does |
|---|---|
get_entity_changelog | Shows which sections of an entry changed, and when, over up to 90 days. |
get_matrix_snapshot | Reads entries exactly as the Matrix had them on an earlier date. |
diff_matrix | Lists what changed between two dates, or field-by-field changes for chosen entries, citing both versions. |
get_event_stream | Lists raw dated observations for entries in time order, before they are merged into the entry. |
What your AI app can and cannot see
It can
- Entries for 3,000+ companies, industries, themes and regions, with sections such as earnings, risk factors, capital allocation and competitive position
- Typed links between entries (supplier, competitor, partner, subsidiary, regulator and more), each with a one-line reason
- Retail discussion for 800+ names: overall stance, how confident that read is, how unusual the attention is, and the threads behind it
- Each entry's change history, and the Matrix as it stood on any date since May 21, 2026 (an entry appears from when it was added)
- Source records behind claims: filing type, article title, publisher, date and link
It cannot
- Your portfolio, watchlist, saved stories or listening history
- Your password or payment details. You sign in on Stoky's own page, never inside the AI app
- Live quotes or real-time market data. Entries only quote dated figures from filings and news
- Change anything. All 15 tools are read-only
To disconnect, remove Stoky Matrix in your AI app's connector or MCP settings. A sign-in that goes unused for 30 days expires on its own.
Included with Stoky Pro
No add-on and no separate API plan: your Stoky subscription covers the Matrix in the Stoky app and in your AI apps. On Stoky Basics, the sign-in page tells you so and nothing is connected. Some AI apps need their own paid plan before you can add a custom connector.
Questions
What is MCP?
MCP (Model Context Protocol) is an open standard that lets AI apps and agents use outside services. The Matrix runs an MCP server, which is why one address works in every app listed here.
Where does the information come from?
From SEC filings (10-K, 10-Q and 8-K) and major financial news outlets. An automated writer reads them, updates the affected entries and links, and keeps the available source records with each update. Retail discussion comes from public investing forums and is always labeled as retail discussion.
How current is it?
The Matrix updates affected entries every few hours as filings and news arrive, and busy names such as Nvidia are often revised several times a day. Freshness varies by entry; most entries show when they were last written, and your AI can check this before it answers.
Is it the same Matrix as in the Stoky app?
Yes. It is the same Matrix behind the Matrix Portal and Noah, read directly by your AI.
Can the answers be wrong?
Yes. The Matrix returns sourced entries, but your AI writes the answer and can misread them. A citation shows where a claim came from; it does not prove the claim. Links marked as co-mentions only mean two names often appear in the news together. Open the cited source for anything that matters.
Why am I asked to sign in again?
A connection stays active while you use it. After 30 days without use, or if your Stoky Pro plan ends, you are asked to sign in again.
What does Stoky see, and how is my data handled?
Stoky sees the lookups your AI app sends to the Matrix, not the rest of your conversation. Your connection is stored as a hashed token and you can remove it at any time. Section 8 of the Stoky Privacy Policy covers AI-app connections. Questions go to [email protected].
Sign-in didn't work. What now?
Sign in the way you usually sign in to Stoky (email and password, Google or Apple) and check that the account has Stoky Pro; on Stoky Basics the sign-in page offers an upgrade instead. If the window closed or timed out, remove Stoky Matrix in your AI app and add it again. Still stuck? Email [email protected].
The connection stopped working.
Your AI app renews access on its own while you use it. After 30 days without use, or if your Stoky Pro plan ends, remove Stoky Matrix in the app and add it again to sign in fresh.
Is this investment advice?
No. The Matrix describes what companies have reported, what the news says and how companies connect. It is for information and research only and is not investment advice.
