What it does

Did It Work? is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

  • list_leaderboards · Per-outcome-family leaderboards from data/ranking/leaderboards.json. Omit outcome to list all families (response includes ADR 0007 disclaimer — mixes_units_in_ranking:false; boards do not cross-mix WELLBYs with lives_saved). Pass outcome= t
  • get_review_queue · Human exception-review queue (read-only). Returns items from data/review/queue.json for Ho Hum (sole human operator). Default status=open; pass status=all for history. Approve/reject is offline file edit only — write_api is always false; th
  • compare_charities · Side-by-side claims, recommendation tiers, and trust for two or more org_* ids.
  • estimate_impact · Modeled expected outcomes from verified org claims scaled by gift_usd. Always modeled:true and guaranteed:false. Never invents CE; returns insufficient_data when no usable verified unit.
  • get_org · Fetch one organization / program / fund record by stable org_* id.
  • search_orgs · Heuristic search by cause, outcome family, or donor intent phrase. Prefer recommend_charity when the user wants ranked 'best for outcome' results.

  • get_tax · Sanitized trust/tax-status summary for an org with always-on not-tax-advice disclaimer. Prefer before asserting US deductibility. deductibility.assert_personal_deductibility is ALWAYS false — agents must never claim a gift is deductible for

  • create_giving_intent · NO-CHARGE deep-link giving handoff (Phase 3 MVP). Returns mode=deep_link, org donate_url, donation_proof=null, charge=false. Better World never processes payment, stores cards, or calls Stripe. Optional modeled_impact is modeled≠guaranteed.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
