AI agents call search_sec_filings to retrieve information from MetricDuck — Financial Analysis without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though search_sec_filings only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Search the full text of every SEC filing since 2001 to find companies related to any concept — a product, technology, regulation, event, or company. Returns filing-level results with aggregated statistics (company count, form type breakdown, industry distribution). For 10-K/10-Q filings processed by MetricDuck, also shows WHICH SECTIONS contain the term with drill-in pointers. Searchable form types (all SEC forms since 2001): - 10-K, 10-Q — Annual/quarterly reports (section-level drill-down available) - 8-K — Material events, earnings announcements, leadership changes - DEF 14A, DEFM14A, PRE 14A — Proxy statements: executive compensation, board proposals, merger votes - S-1, F-1 — IPO registration statements (new market entrants, competitive landscape) - S-3, S-4 — Shelf registrations, M&A registration statements - 424B series — Prospectus supplements (debt/equity offerings) - N-CSR, N-CSRS — Fund annual/semi-annual reports (institutional positioning) - SD — Conflict minerals disclosure (physical supply chain mapping) - SC 13D, SC 13G — Beneficial ownership (activist investors, large holders) - 20-F, 40-F, 6-K — Foreign private issuer reports - Any other SEC form type — omit form_type to search all The FORM TYPE reveals the context: - 10-K risk factors → dependency, competition, or regulatory exposure - 10-K revenue footnote / business description → customer/supplier/partner - 8-K → material event reaction or announcement - S-1 → new market entrant (IPO in your space) - DEF 14A → executive compensation tied to a metric or initiative - SD → physical supply chain (minerals, manufacturing) - SC 13D → activist investor targeting a company Section-level enrichment (10-K/10-Q only): For MetricDuck-processed filings, results include which sections contain the term (risk factors, MD&A, revenue footnote, etc.) with chunk pointers for immediate drill-in via get_filing_section. Non-standard forms (S-1, DEF 14A, etc.) return filing metadata and accession numbers but no section-level detail. Use cases: - "Who supplies Apple?" → ticker_lookup="AAPL" → companies listing Apple in revenue footnotes - "Recent data breaches?" → query="cybersecurity incident", form_type="8-K" - "Tariff-exposed companies?" → query="tariff", form_type="10-K" → risk factor disclosures - "Activist campaigns?" → query="board representation", form_type="DEF 14A,SC 13D" When to use other tools instead: - You already know the company → get_filing_index (signal triage) or list_filings (filing inventory) - You want financial metrics → screen_companies (numeric filters) - You want earnings call cross-quarter view → compare_earnings_calls Key limitation: keyword matching only, not semantic. "No material weakness" matches "material weakness found." Verify hits with get_filing_section for context. Search tips: quoted exact phrases ("material weakness"); proximity NEAR(5); OR / NOT; trailing wildcards (restructur*). Historical event queries (M&A announcements, lawsuits, restructurings, leadership changes): the default 1-year date_from and rank_by="date" ordering bury historical anchors under mutual-fund NPORT-P holdings. For specific events, prefer form_type="8-K" + widen date_from to before the event + rank_by="relevance" — this surfaces the anchor 8-K in the top results instead of fund noise.. It is categorised as a Read tool in the MetricDuck — Financial Analysis MCP Server, which means it retrieves data without modifying state.
