On 2026-10-18 the server answered initialize and tools/list without a sign-in. First answer in 97 ms.

• Its tools do check whether a listed stock has an on-chain token; identify whose token a contract address belongs to, but not add the stock lookup to a website.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• search_stocks

  Find tokenized stocks by ticker or company name. Returns every match with its issuers and chains, alphabetical by ticker. If a ticker is a real stock but has not been tokenized, this reports that too, which is a correct answer rather than…

• get_stock

  Everything known about one stock: every instrument (one per issuer, with the mechanics union describing how it handles corporate actions), every listing under it (chain, contract address, supply, price), and the events recorded against…

• list_issuers

  Every issuer whose tokens are tracked, in registry order, with the legal wrapper it uses, the chains it issues on, and a link to where that issuer publishes its own rule on who may buy. The rule itself is deliberately not included: it can…

• list_chains

  Every chain carrying tokenized stocks, with its explorer, and the matrix of which issuer has listed what where. Registry order, which is not a ranking.

• list_events

  The corporate-action tape: splits, distributions and multiplier changes read from chain state, each with a transaction hash. Newest first by the time the event took effect, which is chronology and not a ranking.

• get_contract

  What this site holds about one address, in two independent halves. `listings` says what the token IS - the stock, its company, the issuer and the chain - and is present whenever the address is a listing we track. `matches` says what the…

• get_manifest

  What this service offers a machine reader: the free keyless endpoints, the bulk dataset and its price if the paid tier is live, and the licence. No human reader is ever charged or asked to connect a wallet.

• report_gap

  Tell us you wanted something and did not get it: a stock we do not track, a chain a stock is not on, a field no endpoint carries, a tool that does not exist, a figure you believe is wrong, or a path that failed. Call this when another…
