MCP Auto-Detection Implementation Status

Date: 2025-11-07 Session: MCP Server Auto-Detection and Guided Setup Status: ✅ Core Implementation Complete, Documentation Pending

Executive Summary

Successfully researched and implemented the foundation for MCP server auto-detection and guided setup. Key insight: Don’t auto-install - instead, auto-guide with user consent.

Key Achievement ⭐

Created setup-dossier-mcp.ds.md - a comprehensive, self-service dossier that guides users through MCP server configuration in 5-15 minutes.

What Was Completed ✅

1. Schema Extension ✅

File: dossier-schema.json

Added mcp_integration field:

{
  "mcp_integration": {
    "required": boolean,                    // Is MCP server required?
    "server_name": "@ai-dossier/mcp-server",  // npm package name
    "min_version": "1.0.0",                 // Minimum version
    "features_used": [                      // Tools/resources used
      "verify_dossier",
      "read_dossier",
      "list_dossiers",
      "dossier://protocol"
    ],
    "fallback": "manual_execution",         // What if MCP missing
    "benefits": [                            // Benefits of using MCP
      "Automatic security verification",
      "Streamlined execution"
    ]
  }
}

Purpose: Machine-readable metadata for LLMs to detect MCP requirements and fallback modes.

2. Setup Dossier ✅

File: examples/setup/setup-dossier-mcp.ds.md

Comprehensive 400+ line setup guide that:

Checks prerequisites (Node.js, npm, Claude Code)
Presents 3 installation options (npx, global, local dev)
Guides configuration file creation
Handles existing MCP configurations (merge logic)
Provides extensive troubleshooting
Validates successful setup
Works WITHOUT MCP server (solves catch-22)

Installation Options:

npx (recommended) - No install needed, always latest
Global install - Explicit control, fixed version
Local development - For contributors

Troubleshooting Covers:

“Tool not found” errors
Command not found issues
JSON syntax errors
Path problems (Windows)
First-run delays (npx)
Configuration file locations

Validation:

Test 1: List dossiers
Test 2: Read protocol resource
Test 3: Verify dossier security

3. Comprehensive Research ✅

File: Research agent findings (included in this session)

Deep analysis of:

MCP server auto-installation patterns
Security implications (why NOT to auto-install)
Industry best practices (VS Code, Docker, Python notebooks)
User experience patterns
Technical limitations

Key Findings:

❌ Auto-installation violates dossier’s security model
❌ MCP servers can’t modify their own configuration
❌ No API for self-installation or config updates
✅ Detection + guided setup is best approach
✅ npx provides lowest friction for users

What Still Needs to Be Done 📋

High Priority (Should Complete Soon)

1. Update PROTOCOL.md

Task: Add MCP Server Integration section

Content to add:

## 🔧 MCP Server Integration

### Prerequisites Check

Before executing dossiers, LLMs should check if MCP server is available:

1. **Attempt to call MCP tool** (e.g., `list_dossiers`)
2. **If tool available** → MCP server configured, proceed normally
3. **If tool unavailable** → MCP server not configured, check dossier metadata

### MCP Server Not Configured

**If dossier requires MCP** (`mcp_integration.required: true`):

1. **Inform user** about MCP server benefits
2. **Offer setup options**:
   - Run setup-dossier-mcp.ds.md (recommended)
   - Manual configuration instructions
   - Continue without MCP (if fallback allowed)
3. **Wait for user decision**
4. **Proceed based on choice**

### Fallback Modes

- **manual_execution**: LLM performs manual verification
- **degraded**: Reduced functionality, but continue
- **error**: Block execution, require MCP setup

2. Update SCHEMA.md

Task: Document mcp_integration field

Content to add:

Field description
Purpose and benefits
When to use each fallback mode
Examples for different risk levels
Best practices for dossier authors

3. Update SPECIFICATION.md

Task: Add mcp_integration examples

Examples needed:

High-risk dossier requiring MCP
Medium-risk dossier with optional MCP
Low-risk dossier without MCP
Setup/bootstrapping dossier (no MCP required)

4. Update README.md

Task: Add MCP server section

Content to add:

Benefits of MCP server
Link to setup dossier
Quick configuration example (npx)
“Why MCP?” explanation
Comparison: with vs without MCP

Medium Priority (Can Wait)

5-9. Update All Example Dossiers

Files to update:

examples/data-science/train-ml-model.ds.md
examples/database/migrate-schema.ds.md
examples/development/add-git-worktree-support.ds.md
examples/development/setup-react-library.ds.md
examples/devops/deploy-to-aws.ds.md

Changes for each:

Add mcp_integration metadata to frontmatter:

"mcp_integration": {
  "required": false,
  "server_name": "@ai-dossier/mcp-server",
  "min_version": "1.0.0",
  "features_used": ["verify_dossier"],
  "fallback": "manual_execution"
}

Add “Prerequisites” section mentioning MCP setup:

## Prerequisites

### MCP Server (Optional but Recommended)

**First time?** Set up the dossier MCP server:
- Run: `examples/setup/setup-dossier-mcp.ds.md`
- Or see: [MCP Server Setup](../../README.md#mcp-server)

**Already configured?** You're all set!

**No MCP server?** Manual verification available (see Troubleshooting).

Update checksums after changes:

node tools/sign-dossier.js <dossier-file> --dry-run
# Get checksum from output, update frontmatter

Low Priority (Nice to Have)

10. Enhance MCP Server

File: mcp-server/src/index.ts

Add tools:

check_server_health - Verify MCP server functioning
get_server_version - Return version and capabilities

Add resource:

dossier://setup - Link to setup dossier

11. Create Video Walkthrough

Record MCP setup process
Show dossier execution with/without MCP
Demonstrate automatic verification
Publish to documentation site

12. Integration Testing

Test setup dossier on clean system (no MCP configured)
Test on Windows, macOS, Linux
Test with existing MCP configurations
Verify merge logic works correctly

How the Detection + Guidance Flow Works

User Experience

User: "run deploy-to-aws.ds.md"

Claude: I notice the dossier MCP server isn't configured yet.

This dossier uses MCP server for automatic security verification.
Without it, I'll need to do manual verification which is slower.

Would you like to:
1. Set up MCP server now (5 minutes, one-time) ← runs setup dossier
2. Continue with manual verification (this session only)
3. See detailed setup instructions

Your choice?

[User chooses option 1]

Claude: Great! Let me guide you through the setup using the
setup-dossier-mcp.ds.md dossier...

[Executes setup dossier interactively]

Claude: Setup complete! ✅ MCP server is now configured.
Returning to deploy-to-aws.ds.md execution...

[Now uses verify_dossier tool automatically]

Technical Flow

1. LLM reads dossier frontmatter
   ↓
2. Sees mcp_integration.required or features_used
   ↓
3. Attempts: verify_dossier({ path: "dossier.ds.md" })
   ↓
4a. Success → MCP configured, continue
   ↓
4b. Error "tool not found" → MCP not configured
   ↓
5. Check mcp_integration.fallback:
   - "error" → Block execution, require setup
   - "degraded" → Continue with reduced functionality
   - "manual_execution" → Offer setup or manual mode
   ↓
6. If fallback allows, present options:
   - Run setup-dossier-mcp.ds.md
   - Manual configuration instructions
   - Continue without MCP
   ↓
7. User chooses → Execute accordingly

Technical Decisions Made

1. Why NOT Auto-Install?

Security Reasons:

Violates informed consent principle
Supply chain attack vector (npm dependencies)
Post-install script execution risk
Persistence without user awareness
Conflicts with dossier’s security-first model

Technical Reasons:

MCP servers can’t modify their own configuration
Configuration changes require Claude Code restart
No API for self-installation
Requires system-level operations

UX Reasons:

“Magic” setup leads to confusion
Users don’t understand what was installed
Harder to troubleshoot
No mental model of system state

2. Why Guided Setup?

Advantages:

✅ User maintains full control
✅ Explicit consent at every step
✅ Teaches users about the system
✅ Creates mental model for troubleshooting
✅ Transparent about what’s happening
✅ Respects security principles

One-Time Pain:

5-15 minute setup
But lifetime benefit
Users appreciate understanding

3. Why npx as Default?

Compared to global install:

✅ No installation step
✅ Always latest version
✅ Works across projects
✅ Familiar to developers

Tradeoffs:

⚠️ First run downloads package (1-2 sec delay)
⚠️ Requires internet connection initially
⚠️ Less explicit than global install

Decision: Best balance of convenience and control

4. Why Separate Setup Dossier?

Instead of inline setup:

✅ Reusable across all dossiers
✅ Can be run standalone
✅ Comprehensive troubleshooting
✅ Testable independently
✅ Versionable and updatable

Solves Catch-22:

Setup dossier doesn’t require MCP
Can guide MCP setup without MCP
Works in degraded mode initially
