Cursor uses the same mcpServers schema as Claude Desktop. Project config wins over global.

Continue uses an array of server objects rather than a map.

Add to context_servers. Zed hot-reloads on save.

claude mcp add symfony-hexagonal-skill -- git clone https://github.com/aligundogdu/symfony-hexagonal-skill ~/.claude/skills/symfony-hexagonal-skill

One-liner. Verify with claude mcp list. Remove with claude mcp remove.

Use Cases

Real-world ways to use symfony-hexagonal-skill

Scaffold a new bounded context with hexagonal layers

👤 Symfony devs building non-trivial domain logic ⏱ ~60 min advanced

When to use: You're starting a new feature and want the layering right from day one.

Prerequisites

Symfony 6.x+ project — composer create-project symfony/skeleton
Skill installed — git clone https://github.com/aligundogdu/symfony-hexagonal-skill ~/.claude/skills/symfony-hexagonal-skill

Flow

Name the context

Use symfony-hexagonal-skill. Scaffold a 'Billing' bounded context with Invoice aggregate, issue/void commands, and a query for open invoices.✓ Copied

→ src/Billing/Domain, Application, Infrastructure folders with proper separation
Wire the infrastructure

Add a Doctrine adapter for InvoiceRepository behind the domain port.✓ Copied

→ Interface in Domain, implementation in Infrastructure, services.yaml binding
Expose via controller

Add an HTTP adapter with a POST /invoices endpoint that dispatches the IssueInvoice command.✓ Copied

→ Controller calls bus, not repository directly

Outcome: A clean bounded context that won't turn into spaghetti in 6 months.

Pitfalls

Domain depending on Doctrine annotations — Use XML / attribute mapping in Infrastructure, not on domain entities

Combine with: filesystem

Review a PR for hexagonal layering violations

👤 Tech leads on Symfony teams ⏱ ~20 min intermediate

When to use: Reviewing a PR and you want an automated first-pass on layering.

Flow

Run the review agent

Use symfony-hexagonal-skill review agent on this diff. Flag any Doctrine / Symfony FW imports in Domain/, any controller->repository direct calls, any ORM leakage into responses.✓ Copied

→ Concrete findings with file+line
Suggest fixes

For each finding, propose the minimal refactor.✓ Copied

→ Diffs introducing a port or DTO

Outcome: A PR that doesn't silently degrade the architecture.

Combine with: github

Progressively refactor an existing Symfony app toward hexagonal

👤 Teams with a legacy Symfony project ⏱ ~120 min advanced

When to use: Big-bang rewrite is off the table; you want incremental cleanup.

Flow

Identify a seam

Use symfony-hexagonal-skill. Look at src/Module/Orders — what's the smallest slice I can lift into a clean domain?✓ Copied

→ Specific class identified with extraction plan
Extract incrementally

Walk me through the extraction in 3 PR-sized steps.✓ Copied

→ Staged plan with tests preserved at each step

Outcome: A legacy codebase getting better, one PR at a time.

Pitfalls

Extracting too much in one step — PR-sized slices only; the plugin's review agent helps gate each step

Combine with: git

Combinations

Pair with other MCPs for X10 leverage

symfony-hexagonal-skill + github

Gate PRs on layering review before merge

Run the hex review on the open PR in this repo and post findings as comments.✓ Copied

symfony-hexagonal-skill + filesystem

Apply scaffolds into the actual repo

Apply the context scaffold to my project under src/.✓ Copied

Tools

What this MCP exposes

Tool	Inputs	When to call
context_scaffold	context name, aggregates	New bounded context
port_adapter_pair	port interface name, adapter type	Adding infrastructure
layering_review	diff or directory	Pre-merge
refactor_plan	legacy module	Starting a cleanup

Cost & Limits

What this costs to run

API quota: None
Tokens per call: Moderate — reviews scan files
Monetary: Free
Tip: Scope reviews to the diff, not whole repos, to save tokens.

Security

Permissions, secrets, blast radius

Credential storage: None

Data egress: None from skill

Troubleshooting

Common errors and fixes

Review agent misses violations

Ensure the full diff is in context; very large diffs may need chunking

Scaffold produces old Symfony 5 style

Mention your Symfony version explicitly — 6 vs 7 conventions differ

Alternatives

symfony-hexagonal-skill vs others

Alternative	When to use it instead	Tradeoff
Deptrac static analysis	You want rule-based static enforcement of layering	No refactor help; purely gates violations
craftcms-claude-skill	You're on Craft CMS, not Symfony	Different framework
