Whose server it is
  • Registry namecom.howitspread/howitspreadverified in the MCP registry

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

Should an agent connect itConnect it
  • Its tools do every use case we checked: trace how a film or product went viral; review sourced timelines of past viral campaigns.

Once connected

  • For "trace how a film or product went viral", the likely first call is search_cases.
  • For "review sourced timelines of past viral campaigns", the likely first call is search_cases.
  • Parameters are untyped or undescribed in 1 of 3 tools: check arguments before calling.

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 (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). 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 →

  • get_case

  • list_mechanics

    The closed vocabulary of spread mechanics, each defined, with how many cases use it.

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.
