Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

13d
search_13d_filings
Search recent SEC Schedule 13D / 13G filings from the past 72 hours. Args: activist: Filter to filings tagged with this activist filer name. Substring match, case-insensitive. Examples: 'Saba', 'Starboard', 'Icahn', 'Elliott', 'Pershing'. min_percent: Minimum percent of class disclosed. include_amendments: Include 13D/A and 13G/A amendments. Default True. include_passive_13g: Include passive Schedule 13G filings. Default False (only active 13D / 13D/A returned). limit: Max results (1-50, default 25). Returns: JSON list of filings with cusip, percent_of_class, aggregate_amount, activist_filers, and an Item 4 purpose excerpt.
atm
search_atm_offerings
Search recent SEC at-the-market (ATM) equity offerings from the past 72 hours. Pulls from S-3 / 424B5 family filings where our parser flagged ATM-offering indicators in the body language. Args: sales_agent: Filter by sales agent name (substring, case-insensitive). Examples: 'Cantor Fitzgerald', 'Jefferies', 'Roth Capital', 'H.C. Wainwright'. min_shelf_million_usd: Minimum shelf size in millions USD. limit: Max results (1-50, default 25). Returns: JSON list with shelf_size_usd, is_atm, sales_agents, use_of_proceeds_excerpt.
filing
get_filing
Fetch one filing by SEC accession number, regardless of recency. Useful when an agent has an accession number from a citation or earlier tool call and needs the parsed details. Args: accession_number: SEC accession in 'XXXXXXXXXX-YY-NNNNNN' format. Returns: JSON for the filing if found in our archive, or {"found": false}.
filings
search_8k_filings
Search recent SEC 8-K filings (current report) from the past 72 hours. Args: items: Comma-separated 8-K item codes to filter on. Examples: '1.05' (cybersecurity), '5.02' (officer departure), '8.01' (other events), '1.01' (material agreement). Leave None for all 8-Ks. suspected_buried_only: If True, return only filings where our body-text classifier flagged a suspected misclassification — i.e. cyber language under Item 8.01 that should have been 1.05, officer-departure language under 8.01 that should have been 5.02. limit: Max results (1-50, default 25). Returns: JSON-formatted list of filings. Each includes: accession_number, company_name, filed_at, filer_reported_items, detected_items, discrepancy_items (in body but not reported), and suspected_buried_events (map of reported→suspected).

FilingFirehose — questions

Answers built from our own checks of this server.

What can FilingFirehose do?
It exposes 4 tools, read directly from the server on our last check. Among them: get_filing, search_13d_filings, search_8k_filings, search_atm_offerings. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is FilingFirehose working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 427 ms. The bar chart above shows every period we have measured.
How do I connect FilingFirehose?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does FilingFirehose need an API key?
No. FilingFirehose completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is FilingFirehose?
It answers our handshake in 427 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is FilingFirehose open source?
Yes — it is published under the MIT licence, written in Python and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
