  live 401 responses from https://api.pulsemcp.com/v0.1/servers and

  The PulseMCP Registry API is protected by a single API-key scheme carried in a
  custom request header, plus a second custom header that selects the tenant.
  There is no OAuth, no OIDC, no mTLS, and no self-service key issuance: keys are
  granted only by emailing hello@pulsemcp.com, which makes this a sales-gated API
  with a fully public reference.

      "Your tenant identifier". Selects which curated sub-registry view the key
      reads. The MCP server validates it against /^[a-zA-Z0-9_-]*$/ with a 256
      character maximum, and can switch it at runtime via its switch_tenant_id
      admin tool.

    Email hello@pulsemcp.com. The /api page states PulseMCP is "working directly
    with partners to provide an enriched, curated, quality-controlled MCP server
    registry offering customized to the needs of the partner business" — there is
    no signup form, no developer dashboard, and no free tier documented.

    Several response fields (remotes[].isSelfHosted, remotes[].authOptions,
    remotes[].tools, packages[].authOptions, packages[].tools) are marked Premium
    and are activated per tenant by contacting hello@pulsemcp.com.
