Feature & Specification Comparison

Specification	AI Diagram Maker MCP erajasekar Architecture & Design	Tentra MCP rdanieli Architecture & Design
Summary	MCP server for AI Diagram Maker — generate flowcharts, sequence diagrams, ERDs, system/network architecture, UML, mindmap, and workflow from natural language, code, ASCII, images, or Mermaid. Inline rendering using MCP Apps UI and editable diagram URLs. Requires API key.	AI-native architecture platform for engineering teams. Describe a system in natural language (e.g. "payment service with Stripe, Kafka, PostgreSQL") → get an interactive typed diagram with 167 cloud components → export to 14 production frameworks (Java Spring Boot, Python FastAPI, Go chi, Rust Axum, .NET, Kotlin Ktor, Ruby Rails, Elixir Phoenix, Docker Compose, Terraform, Mermaid, ADR, and more). Drift detection (syncarchitecture) scores saved diagrams against live code 0–100 with a structured diff. 9 quality-lint rules catch orphans, SPOFs, god services. Also includes a secondary persistent code-graph layer for AI coding agents (free offline via npx tentra-mcp --local init). Agent-as-LLM pattern — zero LLM cost on our side, zero API key on yours. 35 MCP tools. Works in Cursor, Claude Code, Codex, Windsurf.
