Tools and demonstrations

Open source tools

In addition to bespoke, in-house support we develop free, easy-to-use AI tools to help people working in survey and statistics.

International Classifications MCP

An open-source MCP server that helps AI assistants discover, compare, validate, map, and export official statistical classifications and survey response codelists.

  • Covers 31 classification families and 24,598 searchable records from major international custodians, including ISIC, ISCO, ISCED, COICOP, CPC, ICCS, ICATUS, M49, and FAO classifications.
  • Returns all relevant alternatives as a deterministic ranked shortlist, with versions, provenance, roles, and warnings, rather than silently choosing one standard for the user.
  • Includes 30 independently selectable response codelists from MICS7, DHS-8, Washington Group, JMP WASH, WHO vaccination guidance, and FAO WCA, with safe simple and XLSForm exports.

Development Indicators MCP

An open-source MCP server that helps AI assistants discover, retrieve, and compare official international development indicators through one consistent interface.

  • Connects Codex, Claude, and other MCP-capable assistants to sources including the World Bank, FAOSTAT, ILOSTAT, WHO, UNICEF, IMF, UN SDG, UNESCO, OECD, and ADB.
  • Preserves definitions, units, citations, dimensions, provider codes, status flags, and comparability warnings alongside the figures.
  • Free hosted endpoint with no API key required, plus MIT-licensed source code for anyone who wants to inspect, fork, contribute, or self-host.

Survey Solutions MCP Server

An open-source Model Context Protocol server that gives AI agents a safer, more structured way to work with Survey Solutions Headquarters.

  • Connects Codex, Claude Desktop, and other MCP-capable agents to Survey Solutions through guarded tools rather than raw API calls alone.
  • Supports profile management, read-only inspection, exports, assignment and interview workflows, diagnostics, and controlled write actions.
  • Developed and tested against Survey Solutions Headquarters 26.07 with MIT-licensed source code on GitHub.

Simple BYOK

A lightweight bring-your-own-key chat application for teams that want more control over AI model choice, cost, governance, and data retention.

  • Uses OpenRouter so users can access a range of free and paid models through one interface.
  • Supports organisational control over which models are used, including models with stronger data-retention settings.
  • Built as a practical example of safer AI adoption for non-profits and development organisations.

Survey Solutions AI

A specialised assistant for Survey Solutions Designer that understands the constrained C# environment, validation rules, roster logic, and platform-specific patterns.

  • Designed for questionnaire programmers who need advice that works inside Survey Solutions rather than generic C# suggestions.
  • Supports screenshots and questionnaire exports as richer inputs for better guidance.
  • Includes an educational layer so users learn why suggested code or validation logic should work.

Survey Solutions Universal Dashboard

A prototype universal dashboard for connecting to Survey Solutions servers and presenting interim project results in a more stakeholder-friendly format.

  • Connects to Survey Solutions through the REST API and requests an export rather than modifying server data.
  • Aims to reduce the need for one-off dashboards on every data collection project.
  • Useful as a demonstration of how narrow data tools can sit around existing survey platforms.
