A variant-aware MCP server that exposes different tool sets for different agent types, mirroring the GitHub MCP Server pattern described in SEP-2053's Prior Art section.
Pattern demonstrated: Different tool sets per variant with custom ranking.
| Variant | Tools | Description |
|---|---|---|
code-review |
list_pull_requests, get_diff, add_review_comment |
PR operations and code review |
project-management |
list_issues, create_issue, add_label |
Issue tracking and labels |
security-readonly |
list_security_alerts, get_advisory |
Security scanning (read-only) |
ci-automation |
list_workflow_runs, trigger_workflow |
CI/CD workflow management |
Clients send a "domain" hint during initialization. The ranking function boosts variants whose domain hint matches the client's requested domain, falling back to priority order.
go run ./examples/server/githubConnect any MCP client to http://localhost:8080.
