Spec-Driven Development MCP Server
Provides structured MCP prompts that guide AI agents through a three-stage spec-driven development workflow: generating EARS-format requirements, deriving design documents, and producing implementation code from those specs.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Spec-driven MCP development framework. Development tooling — no production security concerns for the framework itself. Generated servers require standard security review.
⚡ Reliability
Best When
You are starting a new feature or project and want the AI to produce auditable requirements and design artifacts before touching implementation code.
Avoid When
You need fast iteration or your team does not have a culture of maintaining spec documents; the structured overhead will slow you down.
Use Cases
- • Enforcing a requirements-first discipline when using AI for greenfield feature development
- • Generating traceable specs/requirements.md and specs/design.md artifacts before writing code
- • Teams wanting to reduce 'vibe coding' and maintain documentation that outlives a single AI session
Not For
- • Rapid prototyping or exploratory coding where upfront specs add friction
- • Existing codebases that do not benefit from EARS-formatted requirements
- • Workflows where the LLM client does not support MCP prompt invocation
Interface
Authentication
No authentication required; server runs locally and reads/writes files in the project directory.
Pricing
MIT licensed; free to use.
Agent Metadata
Known Gotchas
- ⚠ Exposes MCP prompts (not tools); requires an MCP client that supports prompt invocation.
- ⚠ Stage 2 (generate-design) reads specs/requirements.md; running out of order will fail or produce poor output.
- ⚠ Output files are overwritten on each run with no versioning or backup.
- ⚠ Node.js 20+ required; older environments will fail silently at install time.
