Existing Digital Public Goods expose callable functions that can act as AI Blocks within DPI Workflows. A growing ecosystem is becoming MCP-compatible — enabling AI agents to invoke them directly.
The DPG ecosystem creates a reinforcing cycle: existing DPGs provide callable infrastructure (identity verification, civil registration, health records, payments) that AI Blocks can invoke. New DPGs can be purpose-built as AI Blocks from the outset. And AI Blocks can themselves qualify as Digital Public Goods when they meet the DPGA standards.
Open-source civil registration and vital statistics system. Enables birth, death, and marriage registration with biometric identity linkage.
Open-source payment platform designed for interoperable, real-time, inclusive digital payments. Used for benefit disbursements, G2P payments, and merchant payments.
The world's largest health information management system. Aggregates health data from facility to national level, enabling evidence-based health policy and AI decision support.
Open-source insurance management information system for social health protection programs. Manages enrollment, eligibility, claims, and benefit payments.
Low-code framework for building electronic registries and issuing W3C Verifiable Credentials. Auto-generates CRUD REST APIs from schema configuration — no custom backend required. Powers national registries across health, education, and civil services. Issued 2B+ COVID certificates in India, Indonesia, Philippines, Sri Lanka, and Jamaica. Integrated with DigiLocker and DIGIT.
Open-source workflow automation platform designed for the social sector. Connects DPGs and enables DPI Workflow orchestration. Used by UN agencies, governments, and NGOs in 40+ countries. June 2025: Launched AI Assistant for plain-language workflow generation and a template library (DHIS2, FHIR, CommCare, KoboToolbox), alongside a new MCP server interface enabling AI agents to trigger and inspect OpenFn workflows directly.
Open-source consent management and data governance infrastructure. Enables citizens to manage data permissions, view consent records, and revoke access — a critical AI Block for any DPI Workflow involving personal data.
Open geospatial data infrastructure. Critical for crisis response workflows — identifying affected populations, routing aid, and mapping service coverage. Provides the data layer for area_classify() AI Blocks.
Modular Open Source Identity Platform — one of the most widely deployed open-source identity platforms globally. Used by countries across Africa and Asia to issue national IDs with biometric verification. Exposes robust identity APIs that are AI Block-ready for identity_verify() and enrollment workflows. Comprehensive OpenAPI/Swagger specs across all versions; eSignet provides OpenID Connect layer.
Inji is an open-source verifiable credentials wallet and issuance platform from the MOSIP Foundation. Enables citizens to hold and present tamper-proof digital credentials (ID, health records, education certificates) via mobile. Critical for AI workflows that need to verify credentials without querying a central registry on every interaction. Implements OpenID4VCI draft 13 — structured REST endpoints, predictable for MCP wrapping.
CREDEBL is an open-source Self-Sovereign Identity (SSI) platform that enables governments and institutions to issue, manage, and verify W3C Verifiable Credentials at scale. Now an LF Decentralized Trust project. Built for high-volume credential issuance with enterprise-grade governance. Microservices REST architecture (API Gateway); supports multiple ledgers and ledger-less issuance (did:web, did:key, did:peer).
walt.id provides open-source infrastructure for decentralised identity and verifiable credentials. Widely used by developers building identity-first applications. Supports W3C DID, W3C VCs, SD-JWT (selective disclosure), and OpenID4VC protocols — making it the most interoperable VC toolkit available. Excellent for wrapping as an AI Block in identity verification workflows.
Open-source secure data exchange layer developed by Estonia and Finland (NIIS). The backbone interoperability infrastructure for 20+ governments including Iceland, Faroe Islands, Ukraine, and others. Enables any-to-any secure API calls between government registries — critical DPI plumbing for AI workflows that need to query multiple registries without custom point-to-point integrations.
Ukraine's government digital services super-app, open-sourced for global adoption. First country in the world where digital passports are legal equivalents of physical documents. 14M+ citizens use Diia for 11 digital document types and 70+ government services. Available for other governments to adapt under a public license via Diia.Open Source.
Decentralised digital identity protocol developed by the Government of Buenos Aires. DPG certified. Empowers 3.6M citizens with self-sovereign digital identities (DID) anchored on zkSync Era (ZK-proofs), based on W3C DID standards and Trust Over IP. The first government-led blockchain-based SSI at city scale, using zero-knowledge cryptography for privacy-preserving verification.
The leading open-source electronic medical records platform for low- and middle-income countries, deployed in 44+ countries. OpenMRS v3 (2024) adds a modern interface, FHIR R4 support, and enhanced interoperability with OpenHIE, laboratory systems, and mHealth apps. Used by MSF, Ministries of Health, and global health programs for primary and specialized care data management.
End-to-end open-source platform for government-to-person (G2P) benefit delivery. Manages beneficiary social registries, program eligibility rules, and digital cash transfer delivery. Integrates natively with MOSIP (identity), Mojaloop (payments), and OpenCRVS (civil records). Supports offline registration, verifiable credentials, and self-service portals for beneficiary data updates. DPG certified and backed by UNDP Digital X.
Open-source social protection platform optimised for agricultural programs, farmer registries, and rural benefit delivery. Built on OpenG2P foundations with modules for input subsidies, crop insurance, and agri-program eligibility. Integrates OpenCRVS, MOSIP, and DHIS2 for end-to-end social protection workflows in farming communities.
The Model Context Protocol (MCP) enables AI agents to invoke DPGs as callable tools with governed context exchange. OpenFn launched native MCP server support in June 2025 — the first DPG to do so. All others can be wrapped as MCP tool servers via their REST APIs, and native integration is an emerging capability across the ecosystem.
Evaluated March 2026. No native MCP support found in any repository. All three expose REST APIs wrappable as MCP tool servers.
Most mature API surface of the three. Comprehensive OpenAPI/Swagger specs across all versions (1.1.5, 1.2.0+). eSignet exposes an OpenID Connect authentication layer. No native MCP; straightforward to wrap identity.verify() and authenticate() endpoints as MCP tools. High wrappability.
OpenID4VCI-compliant REST APIs (draft 13). Inji Certify exposes structured credential issuance endpoints; Inji Web adds a browser wallet layer. Standards compliance (W3C VC, OpenID4VCI) makes MCP wrapping predictable and interoperable. No native MCP. Moderate-to-high wrappability.
Microservices REST architecture (API Gateway port 5000/api). Built on Hyperledger Aries/Indy; supports W3C DIDs, AnonCreds, and ledger-less issuance (did:web, did:key). Now an LF Decentralized Trust project. API docs less publicly indexed than MOSIP/Inji — review GitHub directly. Moderate wrappability; no native MCP.
DPGs with well-documented REST APIs are MCP-ready in principle — they can be wrapped as MCP servers without code changes to the DPG itself. Native MCP support is emerging across the ecosystem.
First DPG with a native MCP server interface (June 2025 release). AI agents can now trigger workflows, inspect run logs, and query adaptor schemas directly via MCP. Also added AI Assistant for plain-language workflow generation. See release blog →

Any DPG with a REST API can be wrapped as an AI Block. The pattern is always the same: wrap the API call, declare the governance spec, and make it callable from a workflow engine.
→ This block can now be called from any DPI Workflow as ai.civil_registry_verify_v1() — with governance, audit logging, and replaceability built in.
