# Implementation Plan: DeepWriter MCP Server
## Overview
This plan outlines the steps to implement an MCP server that integrates with DeepWriter's API, following the provided schemas and best practices for security, error handling, and maintainability.
---
## 1. Memory Bank Initialization
- [x] Create all required core files in memory-bank/ to document project context, architecture, technology, and progress.
---
## 2. MCP Server Scaffolding
- Set up a new Node.js/TypeScript project for the MCP server.
- Implement stdio or SSE protocol for MCP tool communication.
- Configure environment variable management (dotenv).
---
## 3. Tool Implementation
Implement each MCP tool as a discrete module, following the provided schemas:
- listProjects
- getProjectDetails
- createProject
- updateProject
- deleteProject
- generateWork
Each tool:
- Validates input against schema.
- Calls the appropriate DeepWriter API endpoint.
- Handles and maps errors to MCP responses.
- Returns output in the specified schema.
---
## 4. API Integration
- Use fetch (node-fetch or native) for HTTP requests.
- Pass API key in x-api-key header.
- Use HTTPS for all requests.
- Implement retry logic for transient failures.
---
## 5. Error Handling & Security
- Centralized error handler for mapping API errors (401, 403, 404, 400, 500).
- Never log API keys or sensitive data.
- Input sanitization and validation.
- Enforce rate limiting and monitor for abuse.
---
## 6. Logging & Resources
- Log activity and errors (excluding sensitive data) for debugging and transparency.
- Expose resources for:
- API key validation status
- Current rate limits
- Usage statistics
- Error logs
- Request history
---
## 7. Testing
- Write unit and integration tests for all tools and error cases.
- Test rate limiting, retry logic, and input validation.
---
## 8. Documentation & Maintenance
- Document usage, endpoints, and maintenance procedures.
- Monitor for DeepWriter API changes and update as needed.
- Maintain up-to-date schemas and error handling.

## Next Steps
1. Review and approve this plan.
2. Switch to implementation mode and begin scaffolding the MCP server project.
