• get_cost_estimate

  mental-health-care

  [Step 1 of cost_check] Returns the cost-estimate tool URL pre-filled with the user's insurance + service if provided, plus the general copay range. The tool URL is a hand-off — the user verifies their plan there for an exact copay. Use when: The user asks "how much does therapy cost?" / "is X insurance covered?" / "what's my copay?" — return both the general range AND the deep-link. Don't use when: The user wants to find a provider — use find_provider (which already filters by accepted insurance). Example: get_cost_estimate({ insurance: 'Aetna', service: '354092' })

Args: project_key: The project key from CLAUDE.md (registered at sncro.net) git_user: The current git username (for guest access control).

Pass this on the second and subsequent create_session calls in the same conversation, once you already know how to use the tools. After calling this, tell the user to paste the enable_url in their browser. Then use the returned session_key and session_secret with all other sncro tools.

• list_profiles

  Unphurl

  List all custom scoring profiles on this account. Returns profile names and their custom weight overrides. Profiles are named weight sets that change how Unphurl scores URLs.

Profiles only override specific weights. Any signal not specified in a profile uses the default weight. Use show_defaults to see all 25 signals and their default weights.

This tool does not require an API key. The defaults are hardcoded and always available.
