MCP Package System - Quick Start Guide

Get started in 5 minutes with packaging your codebase for ChatGPT Projects.


What is MCP Package System?

The MCP (Model Context Protocol) Package System lets you package any part of your codebase into a flat-structure archive optimized for ChatGPT Project uploads. Package by topic, capability, or custom file selection.


Prerequisites

  • Python 3.8+
  • Bash
  • jq (for validation)
  • zip utility

Quick Start: Create Your First Package

Step 1: List Available Topics

cd /path/to/_codex_
./scripts/mcp/mcp-package --list

Output: See all 9 predefined topics (zendesk, agents, quantum, docs, mcp, workflows, python_dev, testing, security)

Step 2: Preview a Package (Dry-Run)

./scripts/mcp/mcp-package --topic mcp --dry-run

Output: List of files that would be included (no package created)

Step 3: Create a Package

./scripts/mcp/mcp-package --topic mcp

Output: package_mcp_20251230.zip created and validated

Step 4: Validate the Package

# Check contents
unzip -l package_mcp_*.zip

# Inspect manifest
unzip -p package_mcp_*.zip manifest.json | jq .

# Verify file count
unzip -p package_mcp_*.zip manifest.json | jq '.files | length'

Expected: Valid JSON manifest with file metadata (SHA256, sizes, paths)

Step 5: Upload to ChatGPT Project

  1. Go to ChatGPT (chatgpt.com)
  2. Create or open a Project
  3. Click "Add files" or drag-and-drop the zip file
  4. ChatGPT extracts and indexes automatically

Step 6: Use the System Prompt

Copy the system prompt from docs/mcp/ChatGPT_Project_SYSTEM_PROMPT.md and paste into your ChatGPT Project instructions.

Test it:

User: "What files are in this dataset?"
User: "Where is the packaging guide?"
User: "Explain the MCP package system"


Common Use Cases

Use Case 1: Package MCP Documentation

./scripts/mcp/mcp-package --topic mcp --output mcp_docs.zip

Result: All MCP system documentation and tools (~24 files, ~0.1 MB)

Use Case 2: Package Agent Implementations

./scripts/mcp/mcp-package --topic agents --output agents_code.zip

Result: All agent code, tests, and docs (~61 files, ~0.2 MB)

Use Case 3: Package Specific Files (Custom)

./scripts/mcp/mcp-package \
  --custom "agents/workflow_navigator.py,agents/quantum_game_theory.py,tests/agents/test_*.py" \
  --output capability_workflow.zip

Result: Only the specified files and matching patterns

Use Case 4: Package Testing Methodology

./scripts/mcp/mcp-package --topic testing --output testing_guide.zip

Result: All tests, pytest config, and testing docs (~1,600+ files)


Via GitHub Actions (No CLI Required)

Step 1: Navigate to Actions

Go to your repository โ†’ Actions tab โ†’ Build ChatGPT Project Package

Step 2: Run Workflow

Click "Run workflow" and select: - Topic: Choose from dropdown (e.g., "agents") - Glob filters: (optional) Override topic with custom patterns - Output name: (optional) Custom filename

Step 3: Download Artifact

After workflow completes, download the artifact from the workflow run page.

Package Structure

Every package includes:

package_<topic>.zip
โ”œโ”€โ”€ manifest.json           # File metadata and mappings
โ”œโ”€โ”€ README_dataset.md       # Dataset overview
โ”œโ”€โ”€ index.md               # Quick reference table
โ””โ”€โ”€ <flat_files>           # src__module__file.py format

Manifest Fields

{
  "version": "1.0",
  "generated_at": "2025-12-30T17:00:00Z",
  "repository": "Aries-Serpent/_codex_",
  "files": [
    {
      "flat_name": "src__agents__workflow.py",
      "original_path": "src/agents/workflow.py",
      "sha256": "abc123...",
      "size_bytes": 12345,
      "language": "python",
      "tags": "agents,source",
      "chunked": false
    }
  ],
  "total_files": 24,
  "total_size_bytes": 123456
}

Troubleshooting

Issue: Package Too Large (>50 MB)

Solution: Use more specific topic or custom filters

# Instead of "testing" (1,600+ files)
./scripts/mcp/mcp-package --custom "tests/agents/**/*.py"

Issue: No Files Selected

Cause: Glob patterns didn't match any files

Solution: Test pattern first

find . -path "your/pattern/**"

Issue: Workflow Fails with "custom topic but no glob_filters"

Solution: Select a predefined topic OR provide glob_filters with custom

# Correct
topic: agents

# OR

topic: custom
glob_filters: "agents/**,tests/agents/**"

Issue: Invalid Manifest JSON

Solution: Check with jq

unzip -p package.zip manifest.json | jq .

If invalid, re-run packaging command.


Best Practices

1. Start with Predefined Topics

Use --list to see available topics. They're optimized for common use cases.

2. Use Dry-Run First

Always preview with --dry-run before creating large packages.

3. Keep Packages Small

Target <30 MB for optimal ChatGPT performance. Split large topics if needed.

4. Name Packages Descriptively

# Good
--output agents_workflow_2025-12-30.zip

# Avoid
--output package.zip

5. Validate Before Upload

Always check manifest and file count before uploading to ChatGPT.

๐Ÿง  Redundancy Patterns

Package Creation Failures: 1. Pre-creation state: No package exists 2. Detection: Command exits with error code 3. Response: Check glob patterns with find command 4. Recovery: Adjust filters or use --dry-run to debug 5. Validation: Successful package creation + manifest validation

Invalid Package Recovery: 1. Symptoms: Malformed manifest, missing files, corrupted archive 2. Detection: jq validation fails or unzip errors 3. Diagnosis: Check package creation logs with --verbose 4. Fix: Re-run packaging command with corrected parameters 5. Prevention: Always use --dry-run first for large packages

ChatGPT Upload Failures: 1. Symptoms: Upload rejected or files not indexed 2. Common causes: Package >50 MB, invalid manifest, malformed files 3. Recovery: Split package into smaller topics or use custom filters 4. Fallback: Manual file upload of critical files 5. Documentation: Update troubleshooting guide with new patterns
