list_exchangesList the exchanges DataSinking covers. Returns exchange codes (nyse / nasdaq / cboe / sse / szse / bj / jpx / ksc / koe / knx / twse / tpex / lse) with the number of reports available per exchange. Call this first to discover coverage. Sources: US = SEC EDGAR, A-shares = cninfo.com.cn, Japan = EDINET, Korea = DART, Taiwan = MOPS, UK = FCA NSM.list_stocksList the stocks on one exchange, including the report count per company.list_reportsList a company's reports — metadata only (id, title, period), no body text. Each item carries a `source` field naming the official disclosure platform; keep that attribution when you cite it.get_reportFetch one report's full text (metadata + Markdown body). The `source` field names the official disclosure platform; keep that attribution when you cite it. Expensive in tokens — prefer get_section when you only need one chapter. Content is annotated with block markers (`<!-- ds:block:N -->`) so you can cite a specific paragraph or table.list_sectionsList every section of a report with its size, before you decide what to pull. Returns `sections` (titles, in order) plus `section_details` — same order, one entry per section with `title`, `has_tables`, `chars` and `estimated_tokens`. Use `estimated_tokens` to avoid pulling a chapter that would blow your context, and `has_tables` to know whether the chapter needs special handling (tables are the part RAG pipelines usually get wrong). Then call get_section with a heading keyword — the headings are in the report's own language.get_sectionFetch only one section of a report by keyword — much cheaper than get_report, best for RAG. Content is annotated with block markers (`<!-- ds:block:N -->`) so you can cite a specific paragraph or table.

get_setup_instructionsShow how to configure e-arveldaja API credentials when the server is running without connections.get_server_statusReport the running e-arveldaja MCP server version, the active tool profile, and any active point-of-use release notices. Read-only; needs no credentials.import_apikey_credentialsPreview and persist apikey*.txt credentials into local/global .env.

Preview-first: the default call projects the removal and returns a plan_handle; call again with execute=true and that handle to delete.list_connectionsList configured e-arveldaja connections and the active index.switch_connectionSwitch active e-arveldaja connection. Clears caches; interrupted in-flight tools are blocked from further API requests.clear_cacheClear cached e-arveldaja API and reference data. Use after changing data directly in the e-arveldaja web UI, or before reports that must reflect the latest upstream state.get_session_logRetrieve mutating-operation audit log Markdown for the current connection, another audit-log label, or connection:<raw name>.list_audit_logsList available human-readable audit log files.clear_session_logClear the audit log for the current connection.
