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 Security60
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 7 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- 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 is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability80
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 861 tokens (~123/item across 7 items; 7 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 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 Stocks On Chain MCP server?
Stocks On Chain is a hosted endpoint at https://stocksonchain.io/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 →
get_contract Look up a contract address ~197
What this site holds about one address: the name and category our registry records and who told us, plus what the code at that address actually is - its runtime bytecode hash, the implementation behind it if it is a proxy, and how many other addresses we track run byte-identical code. The code half is reproducible: fetch eth_getCode and take its keccak256 and you get the same hash. An address that is a token listing but not in the contract registry returns the listing (stock, issuer, chain) with no code record. This never says an address is safe, genuine or correct, and there is no field that could: check it against the issuer before you act on it.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The contract address, in any case. |
| chain | string | – | Chain slug, for example ethereum or robinhood-chain. Optional. Omit it to find the address on every chain we hold it. |
No output schema declared.
No examples provided.
get_manifest Get the agent tier terms ~52
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_stock Get one tokenized stock ~93
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 it. Report instruments as the options; listings are addresses. Read mechanics.kind before reaching for any field inside mechanics.
| Name | Type | Req | Description |
|---|---|---|---|
| ticker | string | yes | Ticker or slug, for example NVDA or nvda. |
No output schema declared.
No examples provided.
list_chains List chains ~40
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_events List corporate actions ~91
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | How many events to return. Default 50, maximum 500. |
| since | string | – | ISO 8601 date. Only return events effective on or after this date. |
No output schema declared.
No examples provided.
list_issuers List issuers ~85
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 change without this site noticing, so answer eligibility questions by sending the caller to eligibility.sourceUrl rather than by stating a rule.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_stocks Search tokenized stocks ~88
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 an empty result.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | A ticker (NVDA) or part of a company name (Nvidia). Case insensitive. |
No output schema declared.
No examples provided.
