GitHub Developer Platform
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.
Variants
| 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 |
Custom Ranking
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.
Run
go run ./examples/server/github
Connect any MCP client to http://localhost:8080.
Demo
See mcp-inspector-variants-demo.mp4 for a walkthrough using MCP Inspector.

Overview ¶
Example: GitHub MCP Server — a developer productivity platform that exposes different tool sets for different agent types using MCP server variants. This mirrors the GitHub MCP Server pattern described in SEP-2053's Prior Art section, where a single server exposes code review, project management, security, and CI/CD tools as separate variants with custom ranking.
Capability demonstrated: Different tool sets per variant, custom ranking.
Variants:
- code-review: PR operations, diffs, and review comments
- project-management: issue tracking, labels, and assignments
- security-readonly: security scanning alerts and advisories (read-only)
- ci-automation: CI/CD workflow management and dispatch
Run:
go run ./examples/server/github
Then connect any MCP client to http://localhost:8080.
