corporate-events-mcp

Cross-jurisdiction corporate events normalization via MCP. A single consistent schema covering earnings dates, dividend announcements, stock splits, and M&A announcements across US (SEC EDGAR), UK (GlobeNewswire/RNS), Canada (GlobeNewswire/CNW), and Australia (ASX Market Announcements).

Replaces Refinitiv Datastream ($10,000-22,000/yr), Bloomberg Terminal corporate actions module ($24,000/yr), and FactSet corporate events data ($8,000-15,000/yr) with a programmatic, agent-callable API.

What it is

No mobile device data. No scraping official registries. All sources are free and public.

Data Sources

MCP Tools

get_company_events

Events for a specific company by ticker, ISIN, or company name substring. On-demand enrichment fires all four sources in parallel if the company is not cached.

Input: { "query": "AAPL", "jurisdiction": ["US"], "event_type": ["earnings"], "days_back": 90, "limit": 20 }

search_events

Filter events by type, jurisdiction, and date range. Served from SQLite — sub-10ms warm.

Input: { "event_type": ["dividend","earnings"], "jurisdiction": ["AU","CA"], "from_date": "2026-01-01", "limit": 50 }

get_recent_events

Latest events across all jurisdictions ordered by ingestion time.

Input: { "hours": 24, "event_type": ["merger_acquisition"] }

get_pipeline_health

Last poll time per source, event counts, status (ok/error/never). Verify freshness before time-sensitive queries.

Input: {} (no parameters)

fetch_historical_events

Historical 8-K filings for a US company from SEC EDGAR back to the early 1990s. Walks filings.files[] pagination. US only.

Input: { "query": "JPM", "from_date": "2015-01-01", "to_date": "2016-12-31", "limit": 200 }

Normalized Event Schema

  "is_amendment": false,
  "amends_id": null
}

Amendment Flagging

is_amendment: true is set when form type is 8-K/A. After upsert, resolveAmendments() queries the DB for the most recent prior 8-K from the same company with matching item types and sets amends_id to link them.

Running Locally

Ticker cache loads ~10 seconds after startup (10,365 US tickers). EDGAR polling runs immediately.

Deployment (Railway)

Push to GitHub, connect repo in Railway. Set DB_PATH=/data/events.sqlite and add a volume mounted at /data to persist events across restarts.

Coverage Notes and Limitations

US (SEC EDGAR): Full coverage, hourly polling, historical depth to early 1990s.

Australia (ASX): ASX MarkitDigital API confirmed working at /companies/{code}/announcements. Background polling rotates 30 ASX200 codes in batches of 10 per cycle. On-demand fetch available for any ASX code.

Canada (GlobeNewswire): GlobeNewswire Canada RSS confirmed working with real TSX tickers and ISIN codes. SEDAR+ does not have a confirmed accessible public API endpoint.

UK (GlobeNewswire): GlobeNewswire UK country feed is sparse. FCA NSM returns HTTP 403. Investegate XML returns 404. UK coverage is best-effort — events_indexed may remain at 0 during quiet periods.

Not implemented: Exchange-validated settlement data (DTCC/CREST/CHESS are commercial), real-time intraday corrections, historical depth for non-US jurisdictions.
