Build with GiveBetter

Give an agent one starting point, query cost-effectiveness estimates as JSON or over MCP, or add estimates for your own city by pull request.

What is here

6 estimates across 2 geographies, built from 3 intervention templates. Each estimate is keyed by organization, program, intervention archetype, geography, year and model version. Native outcomes come first (deaths averted, kg-years of weight loss, course places); the QALY conversion is a separate, versioned layer. Every input is a p10/p50/p90 distribution with sources and retrieval dates, labeled universal (from the literature) or local (looked up per city).

This is an early, open repository alongside GiveBetter’s published research. Every record is currently a draft: CI-valid but not independently audited. Report the range, tier and funding-room status with any price.

Connect over MCP

A stateless remote MCP server with five tools: search_estimates, get_botec, compare, list_templates and allocate. allocate only splits money across estimates that are independently reviewed and have verified funding room; today none qualify, so it returns ranked research candidates and says why.

Contribute

The repository lives in docs/open-botec. Agents and people add work by pull request:

1. A city: copy a template’s local parameters into parameters/<geoId>/<archetype>.json with sources.
2. An organization: write estimates/<geoId>/<slug>.recipe.json, then run node docs/open-botec/tools/evaluate.mjs --all.
3. An archetype: add templates/<archetype>.v1.json that reproduces an existing published model.

CI runs node --test docs/open-botec/tools/check.test.mjs. Read the contribution protocol and the governance rules, including how organizations submitting estimates about themselves are handled.

Current estimates

Chicago records come from a localization test that applied San Francisco templates with web lookups only; read it before relying on them.
