MCP Implementation Example: Door43 Repository Analysis
Practical MCP Implementation
This document provides a concrete example of how an MCP system would analyze Door43 repositories and generate/update guides using the Door43 API endpoints.
Scenario Setup
Situation: A new gateway language organization (es-419_gl) has created repositories that might represent new patterns or variations not covered in existing guides.
MCP Task: Analyze the organization's repositories, identify new patterns, and update guides accordingly.
MCP Action 1: Organization Repository Discovery
HTTP Request:
GET https://git.door43.org/api/v1/repos?org=es-419_gl
Expected Response:
[
{
"name": "es-419_glt",
"full_name": "es-419_gl/es-419_glt",
"description": "Spanish Gateway Language Translation",
"updated_at": "2024-01-15T10:30:00Z"
},
{
"name": "es-419_tn",
"full_name": "es-419_gl/es-419_tn",
"description": "Spanish Translation Notes",
"updated_at": "2024-01-10T14:20:00Z"
}
]
MCP Analysis:
- Identify repository naming patterns
- Note descriptions and update timestamps
- Compare against existing guide coverage
MCP Action 2: Repository Classification
For repository "es-419_glt":
HTTP Request:
GET https://git.door43.org/api/v1/repos/es-419_gl/es-419_glt/contents
Expected Response:
[
{"name": "manifest.yaml", "type": "file", "size": 2048},
{"name": "01-GEN.usfm", "type": "file", "size": 45000},
{"name": "02-EXO.usfm", "type": "file", "size": 52000},
{"name": "LICENSE.md", "type": "file", "size": 1500}
]
MCP Analysis:
- Detected: manifest.yaml (Resource Container indicator)
- Detected: Numbered USFM files (Bible text pattern)
- Classification: Likely Resource Container Bible text type
MCP Action 3: Specification Analysis
HTTP Request:
GET https://git.door43.org/api/v1/repos/es-419_gl/es-419_glt/contents/manifest.yaml
Expected Response:
{
"content": "ZHVibGluX2NvcmU6CiAgaWRlbnRpZmllcjogJ2dsdCcKICAuLi4=",
"encoding": "base64"
}
MCP Processing:
1. Decode base64 content
2. Parse YAML structure
3. Extract key fields:
- dublin_core.identifier: 'glt'
- dublin_core.subject: 'Aligned Bible'
- dublin_core.language.identifier: 'es-419'
- projects: [66 Bible books]
MCP Analysis:
- Repository Type: Resource Container
- Content Type: Gateway Language Bible
- Pattern: Similar to en_ult but different language
- Guide Coverage: Covered by existing Bible Text guide
MCP Action 4: Sample Content Analysis
HTTP Request:
GET https://git.door43.org/api/v1/repos/es-419_gl/es-419_glt/contents/01-GEN.usfm
MCP Content Analysis:
1. Decode and parse USFM content
2. Check for alignment markers (\zaln-s, \zaln-e, \w)
3. Count verses and chapters
4. Analyze USFM marker usage
5. Assess content complexity
Expected Findings:
- USFM 3.0 format with alignment markers
- Spanish text aligned to Hebrew/Greek sources
- Standard Bible book structure
- Compatible with existing Bible Text guide patterns
MCP Action 5: Cross-Repository Pattern Analysis
Compare "es-419_glt" with "en_ult":
Similarities:
- Same manifest structure (dublin_core, projects)
- Same file naming pattern (01-GEN.usfm, etc.)
- Same USFM format with alignment
- Same container type and subject
Differences:
- Language: es-419 vs en
- Text content: Spanish vs English
- Possible versification differences
MCP Conclusion:
- Repository follows established Resource Container Bible pattern
- No new guide needed
- Existing Bible Text guide covers this repository type
- Consider adding multi-language examples to existing guide
MCP Action 6: Guide Coverage Analysis
Check Existing Guide Coverage:
Bible Text Repositories Guide:
- Covers: UHB, UGNT, ULT, UST
- Language Examples: English (en), Hebrew (hbo), Greek (el-x-koine)
- Missing: Spanish (es-419) examples
MCP Recommendation:
- Update Bible Text guide with Spanish examples
- Add multi-language considerations section
- Include es-419_glt as additional example
MCP Action 7: Guide Update Generation
Update Bible Text Repositories Guide:
ADD to examples section:
- Spanish Gateway Language Translation (es-419_glt)
- Manifest example with Spanish language settings
- USFM content sample in Spanish
ADD to processing section:
- Multi-language repository handling
- Language-specific considerations
- Cross-language relationship patterns
ENHANCE best practices:
- Language code handling (BCP 47 compliance)
- Text direction considerations
- Multi-language ecosystem navigation
Scenario Setup
Situation: A new translation tool has created repositories with a different manifest format not covered by existing translationCore or translationStudio guides.
Discovery Phase
API_CALL: GET /api/v1/repos/search?q=translation+tool
Filter results for repositories with:
- manifest.json files
- Unknown generator patterns
- Non-standard manifest structures
Example Discovery:
Repository: user123/hi_ult_new_tool
Manifest contains: {"tool_version": 2, "generator": {"name": "new-translation-tool"}}
Analysis Phase
Download and analyze manifest.json:
- New generator pattern detected
- Different field structure from tC/tS
- Unique file organization approach
Content analysis:
- Similar USFM output to other tools
- Different metadata organization
- Novel project tracking system
Guide Decision
MCP Assessment:
- New tool pattern requires documentation
- Significant differences from existing tool guides
- Sufficient complexity to warrant separate guide
MCP Action:
- Create new guide: "New Translation Tool Format Guide"
- Use existing tool guide template
- Populate with analyzed repository data
- Add to tool-generated format section
Scenario Setup
Situation: Scripture Burrito repositories show new flavor types or ingredient patterns not documented in existing guides.
Pattern Analysis
API_CALL: GET /api/v1/repos?org=BurritoTruck
FOR each Scripture Burrito repository:
Download metadata.json
Extract flavor type and ingredient patterns
Compare with documented patterns
Discovery Example:
New flavor type: "audioBible"
New ingredient roles: "audio", "timing", "transcript"
New scope patterns: verse-level audio segmentation
Impact Assessment
MCP Analysis:
- New flavor type not covered in Scripture Burrito guide
- New ingredient patterns require documentation
- Audio-specific processing needs different handling
MCP Recommendation:
- Update Scripture Burrito guide with audio flavor section
- Add audio ingredient processing instructions
- Include audio-specific best practices
