Public Company Earnings Dates and Reporting Window Finder MCP Server

MCP server for the Mamba Labs Public Company Earnings Dates and Reporting Window Finder actor on Apify.

Give it a domain, ticker, ISIN, LEI or CIK and it tells you when that public company reports, and when to reach out around it: fiscal year end, reporting cadence, the next reporting date, days to event, and the open and close of an outreach window you define.

Timing rows cover US companies only. Identity, venue and classification resolve worldwide across the publishable universe. Reporting dates come from US SEC filing history and exist for US companies alone. A non US company resolves fully and returns a stated timing_unavailable_reason rather than a guessed date, and is still charged as a timing row because the lookup ran.

Five tools, one per actor mode

Tool	Takes	Returns
`resolve_company`	identifiers	identity and venue, 44 fields
`qualify_company`	identifiers	a listed status verdict
`get_reporting_timing`	identifiers	fiscal year end, cadence, next event, the outreach window, 75 fields
`build_company_universe`	filters	a company list
`get_reporting_season`	filters	reporting load per week or month

You never pass mode. Each tool sets it, and each tool exposes only the inputs its mode actually uses.

build_company_universe and get_reporting_season build a list from filters and do not accept company identifiers. Set limit explicitly on both: it defaults to 1000 and you are charged per row returned.

Parameters

Every parameter is optional unless a tool says otherwise. The Tools column names the tools that accept it.

Parameter	Type	Tools	Description
`company_domain`	string	`resolve_company`, `qualify_company`, `get_reporting_timing`	A single bare domain, e.g. stripe.com. The Clay column shape. Used by resolve, qualify and timing.
`company_domains`	string[]	`resolve_company`, `qualify_company`, `get_reporting_timing`	Many domains at once. Used by resolve, qualify and timing.
`tickers`	string[]	`resolve_company`, `qualify_company`, `get_reporting_timing`	Exchange tickers, e.g. NWLG. Matched against the primary ticker and every venue listing.
`isins`	string[]	`resolve_company`, `qualify_company`, `get_reporting_timing`	12 character ISINs.
`leis`	string[]	`resolve_company`, `qualify_company`, `get_reporting_timing`	20 character Legal Entity Identifiers.
`ciks`	string[]	`resolve_company`, `qualify_company`, `get_reporting_timing`	SEC Central Index Keys, with or without leading zeros.
`company_names`	string[]	`resolve_company`, `qualify_company`, `get_reporting_timing`	Legal or trading names. Matched on a normalized name. Former names are not available: the alias table carries tickers and ISINs only.
`exchange_codes`	string[]	all five	ISO 10383 MICs. 18 venues are covered.
`country_codes`	string[]	all five	ISO 3166-1 alpha-2, e.g. US, GB, FR.
`regions`	string[]	all five	Shorthand for a set of venues and countries: us, uk, eu. Widens an explicit exchange or country filter rather than replacing it.
`sectors`	string[]	all five	SEC SIC descriptions, e.g. Pharmaceutical Preparations. Populated on roughly 65 percent of the publishable universe.
`security_types`	string[]	all five	ordinary_shares, depositary_receipt, preferred_shares.
`public_float_bands`	string[]	all five	micro, small, mid, large, mega, unknown. Size runs on public float because market capitalization is not populated anywhere in this dataset.
`fiscal_year_end_months`	string[]	all five	Integers 1 to 12. Fiscal year end is effectively a United States field in this dataset.
`exclude_december_fiscal_year_end`	string (`false`, `true`)	all five	Keep only companies whose fiscal year ends in a month other than December, the accounts whose budget cycle is out of phase with a calendar quarter.
`cadences`	string[]	all five	quarterly, semiannual, annual, unknown.
`operating_companies_only`	string (`false`, `true`)	all five	Drop funds, trusts and other non operating entities.
`exclude_blank_checks`	string (`false`, `true`)	all five	Drop pre deal SPACs. Separate from the operating company filter: a blank check shell is flagged as an operating company and passes every ordinary firmographic filter.
`foreign_private_issuer`	string (`any`, `only`, `exclude`)	all five	Filter on foreign private issuer status.
`us_registrant_only`	string (`false`, `true`)	all five	Keep only companies carrying an SEC CIK.
`min_provenance_confidence`	string (`any`, `high`)	all five	Set to high to exclude rows whose source terms were never read.
`exclude_name_only_matches`	string (`false`, `true`)	all five	Drop rows whose identity link rests on a name and country agreeing rather than on an identifier. Use this wherever a wrong identity link matters.
`exclude_share_alike`	string (`false`, `true`)	all five	Drop rows derived from CC BY-SA sources, whose share alike condition may not suit a closed product.
`listed_only`	string (`false`, `true`)	`qualify_company`	qualify mode. Keep only rows proven to be publicly listed.
`suppress_listed`	string (`false`, `true`)	`qualify_company`	qualify mode. Remove companies proven to be publicly listed, for anyone selling only into private companies. It removes what we can prove is listed; it does not warrant that the remainder is private.
`assume_unmatched_is_private`	string (`false`, `true`)	`qualify_company`	qualify mode. By default an unmatched company returns is_listed null, because a non match may mean the company is private OR that we do not hold its domain. Set true to opt into reading a non match as private, which sets is_listed false.
`event_types`	string[]	`get_reporting_timing`, `get_reporting_season`	full_year_results, half_year_results, quarterly_results, trading_update, annual_report_publication, sustainability_report_publication, agm, proxy_filing, capital_markets_day.
`window_lead_days`	string	`get_reporting_timing`	How many days before the event the outreach window opens. Default 70.
`window_lag_days`	string	`get_reporting_timing`	How many days before the event the outreach window closes. Default 42. Must be less than the lead.
`window_statuses`	string[]	`get_reporting_timing`	Keep only rows in these window states: open, not_yet, closed_passed, no_event.
`max_days_to_event`	string	`get_reporting_timing`	Drop rows whose next event is further away than this. A cost control.
`min_cadence_confidence`	string	`get_reporting_timing`	0 to 1. Rows whose cadence confidence falls below this return a null timing block with a stated reason rather than a guess. Quarterly cadence averages 0.94, annual 0.40, semiannual 0.21.
`include_constrained_period`	string (`true`, `false`)	`get_reporting_timing`	Emit the period in which a listed company is constrained in what it can announce, derived from the same window numbers. Useful for campaign and announcement timing.
`limit`	string	`build_company_universe`, `get_reporting_season`	Maximum rows for universe and season. Truncation is always reported, never silent.
`season_group_by`	string (`week`, `month`)	`get_reporting_season`	season mode. Bucket size.
`season_split_by`	string (`none`, `sector`, `country`, `exchange_code`)	`get_reporting_season`	season mode. Optional second dimension.
`season_from`	string	`get_reporting_season`	season mode. ISO date. Defaults to today.
`season_to`	string	`get_reporting_season`	season mode. ISO date. Defaults to 180 days from today.

Reading the output

Dates are predicted, not announced. next_event_is_estimate is true for a date derived from filing history. confidence_band sits at 0.80 and 0.50, computed on the weakest link in the chain, so confidence_effective is the minimum of the event and cadence confidences rather than an average.

window_status is the field to filter on. It is open, not_yet, closed_passed or no_event against today. no_event is the state a company lands in when there is no reporting event to build a window from.

Unknown cadence is refused, not guessed. A company whose filing history is too short or irregular returns a null cadence with a reason instead of an invented date.

A row that resolves nothing is still billed. An identifier that matches no public company returns match_method of no_match with every other field null. That is a real answer and the lookup ran to produce it.

Cost

Pay per event on Apify, charged for rows returned rather than rows filtered out.

Event	Price
Company resolved	$0.006 per row
Timing row returned	$0.012 per row
Reporting season aggregate	$0.05 per row
Actor start	$0.00005 per run

Volume discounts of 5, 10 and 15 percent apply on the Apify Bronze, Silver and Gold plans. A timing row is never additionally charged as a resolved company.
