Available tools 21

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

company

uk_company_profile

Full Companies House profile for a company number: status, SIC codes, registered office, accounts and confirmation statement dates, plus the first page of officers (up to 35), with explicit total/coverage metadata. Primary source, cached for up to 24 hours, provenance attached.

uk_company_search

Search the UK Companies House register by name or number. Returns candidate companies with number, status, type, incorporation date and registered address, with provenance. Primary source with retrieval timestamp; cached for up to 24 hours.

adverse

adverse_media

Roadmap probe, not yet served: adverse media screening with citations. Calling records the requirement and returns not-covered.

capability

find_capability

Search live and honestly planned data capabilities. Searches inform build priority.

charge

charge_register

Roadmap probe, not yet served: outstanding charges and security for a UK company. Calling records the requirement.

counterparty

counterparty_evidence

In one call, assemble a Companies House candidate and profile with optional GLEIF and sanctions evidence. Supply a company number for a direct lookup, or a name and optional registered postcode for candidate resolution. Exact title matches are preferred; ambiguous or fuzzy-only matches are flagged for review. This is evidence assembly, not identity verification, a KYB decision, or sanctions clearance.

cross

cross_registry_resolve

Roadmap probe, not yet served: resolve a company across Companies House, GLEIF, OpenOwnership and sanctions lists into one entity record with per-assertion provenance. Calling records the ask and returns not-covered.

director

uk_director_changes

Roadmap probe, not yet served: per-entity change feed for officer appointments and resignations, priced per delta. Calling records the requirement and returns not-covered.

entity

entity_match

Compare two company references using supplied company-number/LEI equality and normalised name similarity. When one reference has a UK company number and the other only a name, optionally corroborates against Companies House. LEIs are compared as supplied, not validated against GLEIF by this tool. Returns a verdict, heuristic confidence and signal provenance.

fca

fca_register_check

Roadmap probe, not yet served: authorisation status of a firm or individual on the FCA register. Calling records the requirement.

lei

lei_lookup

Resolve a legal entity to its Legal Entity Identifier via the GLEIF API. Supply identifier_type as lei or name, and identifier_value accordingly. Returns LEI, legal name, jurisdiction, status and registration dates. CC0 source data, provenance attached.

psc

uk_psc_ubo

CompanyVerify — questions

Answers built from our own checks of this server.

What can CompanyVerify do?

It exposes 21 tools, read directly from the server on our last check. Among them: adverse_media, charge_register, counterparty_evidence, cross_registry_resolve, entity_match, eu_vat_check and 15 more. 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 CompanyVerify working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 197 ms. The bar chart above shows every period we have measured.

How do I connect CompanyVerify?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does CompanyVerify need an API key?

No. CompanyVerify completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is CompanyVerify?

It answers our handshake in 197 ms on average, which is faster than 68% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
