Which servers in the official MCP registry are Toolcall's own, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry nameclick.toolcall/toolcallverified in the MCP registry

The registry name sits under toolcall.click. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-23 the server answered initialize and tools/list without a sign-in. First answer in 30 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: check a domain's registration age and mail setup; verify email deliverability without sending any mail; fetch chemical hazard data by CAS number.
  • Checked on 4 of the 7 days it takes to judge reliability.

Once connected

  • For "check a domain's registration age and mail setup", the likely first call is domain-check.
  • For "verify email deliverability without sending any mail", the likely first call is email-validate.
  • For "fetch chemical hazard data by CAS number", the likely first call is chem-safety.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
