PopNx MCP’s three pillars

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • search_company

    Search authoritative company registries by company name to resolve candidate legal entities and registration identifiers. Currently supports the United Kingdom (GB) and Norway (NO), with expanding jurisdiction coverage. Results are public-register evidence, not a KYC or KYB compl

  • get_entity_owners

  • get_historical_fx_rate

  • lookup_lei

    Retrieve normalized public legal-entity reference data from GLEIF for an exact 20-character LEI. Use to resolve a known identifier to its legal name, status, jurisdiction, and public addresses; records reflect LEI submissions and are not independent verification. Price: $0.0052 p

  • get_lei_relationships

    Retrieve normalized direct and ultimate accounting-consolidation parent identifiers reported to GLEIF for an exact LEI. Use for public corporate-hierarchy research; reporting exceptions are returned as warnings and absence is not proof that no ownership relationship exists. Price

  • search_sec_company

    Search the official SEC company ticker reference data by issuer name, ticker, or CIK and return bounded normalized candidates. When a CIK is unknown, select a matching candidate and pass its cik to get_sec_filings in a separate paid request. This reference list is not a complete

  • get_timezone

    Resolve an IANA time-zone identifier and convert an optional ISO timestamp using the Worker runtime time-zone database. Use for deterministic local-time and UTC-offset calculations; government rules can change and the exact embedded tzdb release is runtime-controlled. Price: $0.0

  • screen_wallet

    Checks whether an exact digital-currency address appears in the authoritative sanctions datasets currently supported by CelerAPI. This is exact sanctions-list membership lookup, not blockchain-risk analysis or a compliance determination. Price: $0.0060 production USDC via x402 on

Common questions

Is CelerAPI safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.7.0-rc.1) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
