Financial intelligence · Watch & notify

UK company intelligence,
built for your AI agents.

plaingraph turns UK Companies House and filed accounts into clean, agent-callable APIs. Pull the latest implied valuation, balance sheet, runway, outstanding charges, and governance signals for any UK company — over a hosted MCP server or a plain REST API. Subscribe agents to meaningful changes via HMAC-signed webhooks or poll via MCP. Every value links back to the filing it came from.

Every numeric field carries a coverage flag (ixbrl / pdf_heuristic / unavailable); derived valuations carry a confidence band and the source filing date. plaingraph surfaces evidence — your agent (or your analyst) makes the decision.

Financial intelligence

Balance sheet, P&L, cash flow, runway, headcount — and the latest implied valuation derived from filed share allotments. Parsed from iXBRL and e-filed PDF accounts.

Watch & notify

Subscribe agents to meaningful changes — accounts filed, priced rounds, charges, officer departures, status changes. HMAC-signed webhooks or MCP poll, with replayable history.

Provenance & coverage flags

Every value links to its source filing. Every parsed numeric carries a coverage flag, so an agent can't silently treat a missing field as a clean read.

Built on the same provenance-first graph as our KYB and sanctions-screening surface — composable when you need compliance context.

FAQ

What is plaingraph?

plaingraph is an agent-native data layer for UK company intelligence. Get the latest balance sheet, P&L, implied valuation, charges, and governance signals for any UK company that files with Companies House — over a hosted MCP server or a plain REST API.

How do AI agents access plaingraph?

Through a hosted MCP (Model Context Protocol) server so agents can call it directly, or over a plain REST API. The same endpoints power both — you can build your own MCP on them if you prefer.

What financial data is available?

Balance sheet (equity, total assets, current assets, cash, liabilities), profit & loss (turnover, gross / operating / net profit), cash flow, employee count, director remuneration, share capital, plus a derived implied valuation from the most recent priced share allotment (SH01). Outstanding charges (secured debt) and governance signals — late filings, auditor changes, officer churn, going-concern flag — are surfaced as separate tools.

How does Watch & Notify work?

Subscribe an API key to a company number and an event-type list — accounts filed, share allotment, charge created or satisfied, officer change, status change. Receive HMAC-signed webhooks, or poll via the MCP watch_events tool. Subscribe is idempotent; the event log is replayable.

Which companies have the best coverage?

Companies filing iXBRL accounts (currently ~40% of UK filings; mandatory from 2027) have the richest data — full balance sheet plus P&L. Companies filing e-PDF accounts get balance sheet basics via heuristic extraction. FRS-105 micro-entities file no P&L by law. Every numeric field carries a coverage flag (ixbrl / pdf_heuristic / unavailable) so the source is always visible.

Do you also do KYB and sanctions screening?

Yes. The same provenance-first graph powers a KYB surface — officers, persons with significant control, disqualified directors — and sanctions screening against the UK Sanctions List and the OFAC Specially Designated Nationals (SDN) list. Available on the same MCP server when you need compliance context.
