Government technology serves hundreds of millions of people, but building for the public sector means navigating procurement requirements, accessibility standards, and legacy system integrations that would make most startup developers run. Claude Code with the CKAN Open Data MCP helps govtech developers build faster while meeting compliance requirements.
The Challenge
Govtech developers face:
- Legacy integration — government systems run on COBOL, mainframes, and decades-old databases. New software needs to interface with systems that predate the web
- Accessibility requirements — Section 508, WCAG 2.1 AA, and agency-specific standards are non-negotiable. Every interface must be accessible
- Open data mandates — many agencies are required to publish data in machine-readable formats. Building and maintaining data portals is a constant effort
- Security and compliance — FedRAMP, FISMA, and agency-specific security frameworks add layers of requirements to every deployment
CKAN Open Data MCP: Government Data at Your Fingertips
The CKAN Open Data MCP connects Claude Code to CKAN-powered open data portals (used by data.gov, dozens of city and state portals, and international governments), letting you search datasets, download resources, and explore metadata.

}Available Tools
- search_datasets — find datasets by keyword, organization, tag, or format
- get_dataset — fetch full dataset metadata including resources, update frequency, and license
- list_resources — get downloadable resources (CSV, JSON, API endpoints) for a dataset
- download_resource — download a specific resource file
- list_organizations — browse publishing organizations
- get_datastore — query CKAN DataStore tables directly with filters and pagination
Workflow: Building a Civic Data Dashboard
1. CKAN Open Data MCP — Claude searches for relevant datasets (crime stats, transit data, budget allocations), reads the metadata to understand update frequency and format, and generates a data ingestion pipeline.
2. PostgreSQL MCP — store and normalize data from multiple government sources into a unified schema. Claude writes the ETL logic and ensures proper indexing for dashboard queries.
3. GitHub MCP — all civic tech should be open source. Claude manages the repo, writes documentation, and creates issues for community contributors.
4. Filesystem MCP — process bulk data downloads (census data, geospatial files) that are too large for API-based ingestion.
Accessibility-First Development
Claude Code is particularly useful for govtech because it can:
- Generate WCAG 2.1 AA compliant components from the start
- Add proper ARIA labels, keyboard navigation, and screen reader support
- Audit existing code for accessibility issues
- Create accessibility testing scripts
When you tell Claude you're building for government, it defaults to accessible patterns rather than treating accessibility as an afterthought.
