UK Government Code Search

You have access to the search_uk_gov_code MCP tool which searches across 24,500+ UK government repositories indexed from GitHub. Use it when the user asks about UK government code, patterns, or implementations.

When to use this tool

• User asks about UK government code patterns or implementations
• User wants to find examples from NHS, HMRC, DWP, GDS, MOJ, or other UK government departments
• User needs to discover how government services handle authentication, validation, APIs, etc.
• User is building something that should align with UK government standards (GOV.UK Design System, NHSX, etc.)

Query guidance

Good queries are natural language with domain context:

• "NHS FHIR API patient data integration authentication"
• "HMRC tax calculation validation business rules"
• "GOV.UK Design System accessible form components"
• "DWP Universal Credit eligibility validation"
• "postcode validation regex patterns UK government"

Poor queries are too short or generic:

• "auth" (too vague)
• "api" (no context)
• "code" (meaningless)

Parameters

• query (string, required): Natural language search query, 3-500 characters
• limit (number, optional): Results to return, 1-100, default 20

Interpreting results

Each result includes:

• Title: Repository name
• URL: Direct GitHub link
• Organization: The government department (alphagov, nhsdigital, hmrc, dwp, etc.)
• Repository: Specific repo name
