Integrating ChatStack with AI Coding Tools
Optimize Your “Vibe Coding” Workflow with Structured PRDs and Persistent Context
The biggest challenge in AI-driven development is Context Drift. Without a structured plan, AI coding assistants (Cursor, Claude Code, Windsurf) eventually lose track of the project architecture, leading to technical debt and “spaghetti code”.
ChatStack solves this by providing a machine-readable “Single Source of Truth” that you can inject directly into your development environment.
For positioning beyond IDE setup, read how ChatStack compares to generic AI chat for software planning and a requirements-first workflow for vibe coding and AI IDEs.
1. The .cursorrules File: Your Project’s Constitution
When you generate a PRD with ChatStack, we also provide the logic for your .cursorrules file. This file acts as a permanent instruction set for Cursor, ensuring it follows your specific standards every time you prompt.
ChatStack-injected rules include:
- Observability: Automated instructions for logging, error handling, and performance monitoring.
- Security-First Coding: Hardcoded constraints to prevent common vulnerabilities (e.g., SQL injection, improper auth patterns).
- Testing Protocols: Specific requirements for unit and integration tests for every new feature generated.
- Architecture Guardrails: Ensuring the AI adheres to your chosen stack (e.g., Flutter, React, Next.js, Supabase etc.).
2. How to Connect ChatStack to Your IDE
Recommended journey when starting from nothing: interview MCP (no PAT) → submit_prd → open the portal → mint a PAT → portal MCP (CRM). Machine-readable URLs and JSON configs: Markdown twin.
- Portal MCP (production):
https://mcp.chatstack.app/mcp - Interview MCP (production):
https://interview-mcp.chatstack.app/mcp - Interview MCP (staging):
https://interview-mcp-staging.chatstack.app/mcp
Option A: Portal MCP (stdio or hosted)
After a PRD exists in the portal, mint a personal access token (Settings → API access) and register @chatstack/mcp with CHATSTACK_API_URL, CHATSTACK_TOKEN, and CHATSTACK_MCP_TOOLSET=crm — or use the hosted portal MCP URL above with the same Bearer token (no local Node). Tools cover packs, artifact writes, and Improve/Build generate. Do not use the marketing-site submit API key here. REST discovery: portal /api/agent.
Option A2: Public interview MCP (no PAT)
Connect to the hosted interview MCP URL (no Authorization header). Call start_session first, then turns / actions / submit_prd. Daily per-network limits apply. Then mint a portal PAT and switch to portal MCP for CRM tools.
Option B: Markdown (.md), CSV & JSON Export (Portable Context)
If you prefer a manual setup or are using a platform that doesn’t yet support MCP:
- Download your comprehensive PRD as a structured JSON or CSV file.
- Drop this file into your project’s root directory.
- Reference it in your system prompt: “Always refer to @prd.json for technical specifications and architecture logic.”
3. Creating the Execution Plan
A PRD tells the AI what to build; an Execution Plan tells it how to build it step-by-step.
ChatStack provides optimized prompt templates that transform your PRD into a “Master Execution Plan.” This prevents the AI from trying to build the whole app at once—which usually fails—and instead guides it through a logical, modular build order (Database → Auth → API → Frontend).
4. Expert Guidance & Workshops
Setting up an “Agentic Workflow” can be complex. Our team offers specialized consulting and workshops to help your developers:
- Custom .cursorrules Design: We help you write the perfect rules for your specific industry (e.g., HIPAA compliance for HealthTech).
- Execution Plan Audits: We join your team for a workshop to map out the most efficient build sequence based on your ChatStack cost estimate.
- Jira/DevOps Integration: We show you how to sync your structured PRD with your existing project management tools.
Comparison of Workflows
| Feature | Standard “Vibe Coding” | ChatStack + IDE |
|---|---|---|
| Context Source | Random Chat History | Structured JSON PRD |
| Code Consistency | Low (Varies by prompt) | High (Fixed .cursorrules) |
| Integration | Copy/Paste | @chatstack/mcp or file export |
| Security/Testing | Often forgotten | Built-in Guardrails |
