Configuration Notes¶

Volume Mounts¶

Git Server: Read-only workspace access, Git config, SSH keys
Filesystem Server: Full workspace access with security controls
Memory Server: Persistent data volume (mcp_memory_data)
PostgreSQL: Configuration directory mount

Network Configuration¶

All servers run on the ai-dev-mcp bridge network
Subnet: 172.20.0.0/16 (masked for security)
Internal communication on port 8000
External access via mapped ports (9001-9010, 9000 for gateway)

Health Checks¶

Core MCP Servers: Python module import tests
External Services: HTTP health endpoint checks (/health)
PostgreSQL: Database readiness checks (pg_isready)

Security Considerations¶

Filesystem Server: Directory access controls and read-only restrictions
GitHub/GitLab/SonarQube: Token-based authentication
Memory Server: Size limits (1GB default)
Fetch Server: Response size limits (10MB default)

Usage Examples¶

Git Operations¶

# Via MCP client
mcp-call git_status
mcp-call git_commit --message "Update documentation"

File Operations¶

# Via MCP client
mcp-call read_file --path "/workspace/README.md"
mcp-call list_directory --path "/workspace"

GitHub Integration¶

# Via MCP client
mcp-call create_issue --title "Bug Report" --body "Description"
mcp-call list_pull_requests --repository "owner/repo"

Knowledge Graph¶

# Via MCP client
