A side-by-side look at the DataSinking and E Arveldaja MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose DataSinking for finance & fintech work as a local process; choose E Arveldaja MCP for finance & fintech as a local process. You can also run both side by side in one mcpServers block.

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 verifies and projects the target and returns a plan_handle; call again with execute=true and that handle to persist. overwrite=false appends different credentials as another connection.list_stored_credentialsInspect credentials stored in local/global .env files.remove_stored_credentialsPreview and remove one stored credential block from a local/global .env file. 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. DESTRUCTIVE — cannot be undone.list_clientsList clients. Paginated. Brief view by default; use view='full' or get_client for detail.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
