Unmeasured means there is not enough evidence to decide. How these checks work
Start using Calmido Phone Number Lookup
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.
Claude Code
claude mcp add --transport http calmido-phone-number-lookup https://www.calmido.com/api/mcpCapabilities
Retrieve who is behind a phone number from the Calmido directory: the community verdict, the number of reports, the most reported category and the registered business, with a link to the evidence. The id is the one `search` returned: the number in E.164 digits.
DiscoveredLook up who is behind a phone number in the Netherlands, Belgium or Luxembourg: community reports, spam and scam categories, a trust verdict, and the registered business if there is one, from the Calmido phone directory. Use it whenever someone asks who called them, whether a number is safe, spam or a scam, or which company a number belongs to. Accepts international (+31 20 123 4567) and national (020 123 4567) formats; pass `country` for a national number outside the Netherlands. The verdict is one of: business (no reports, a known registered business), empty (no reports and no known business: not a sign that the number is safe), neutral (reported, but not enough evidence to flag), safe (reported, and the community found nothing alarming), suspicious (flagged as a threat), restricted (the identity was erased on request; the reports remain) or unavailable (the lookup could not be read: it says nothing about the number). An invalid number returns an error. Calls are rate limited per address; over the limit the error says how many seconds to wait.
DiscoveredFind a phone number in the Calmido directory (Netherlands, Belgium, Luxembourg). The query is a phone number, international (+31 20 123 4567) or national (020 123 4567); it is not a name or free text. Returns the matching directory entry, if any. Pass its id to `fetch` for the verdict and reports.
