These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

search_by_isin

Search for financial instruments by ISIN (International Securities Identification Number). Returns FIGI identifiers and instrument details.

search_by_cusip

Search for financial instruments by CUSIP (Committee on Uniform Securities Identification Procedures). Returns FIGI identifiers and instrument details.

search_by_sedol

Search for financial instruments by SEDOL (Stock Exchange Daily Official List). Returns FIGI identifiers and instrument details.

search_by_ticker

Search for financial instruments by ticker symbol. Returns FIGI identifiers and instrument details. Automatically tries multiple security types (Common Stock, Preference, Depositary Receipt, ETP) if not specified.

search_by_bloomberg_id

Search for financial instruments by Bloomberg Global ID. Returns FIGI identifiers and instrument details.

batch_mapping

Map multiple financial identifiers to FIGIs in a single request. Supports up to 100 identifiers per request.

validate_identifier

Validate the format of a financial identifier (ISIN, CUSIP, SEDOL, or Bloomberg ID).

get_rate_limit_status

Get the current OpenFIGI API rate limit status.

parse_identifiers

Parse and auto-detect financial identifiers from CSV/text data. Supports tickers with exchange codes (e.g., "AAPL US", "ABLI SS"), ISINs, CUSIPs, SEDOLs, and Bloomberg IDs. Automatically detects the identifier type and extracts exchange codes when present.

search_auto_detect

Automatically detect the identifier type and search for a single financial instrument. Supports ISINs, CUSIPs, SEDOLs, Bloomberg IDs, and tickers with optional exchange codes (e.g., "AAPL US").

batch_search_auto_detect

Parse identifiers from text/CSV and search for all of them in a single batch operation. Automatically detects identifier types. Great for processing lists of tickers or identifiers from spreadsheets.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

22/22 tools missing one or more hints — search_by_isin (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_by_cusip (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_by_sedol (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +19 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Production dependencies are patched

0 critical, 6 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dev dependencies

1 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
