In-depth architectural comparison of the Mockit MCP and Tentra MCP MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Mockit MCP
Architecture & Design · Remote HTTP/SSE
Quality: 53/100 (Good) | Auth: other
Tentra MCP
Architecture & Design · Local stdio
Quality: 55/100 (Good) | Auth: other
Verdict Summary: Choose Mockit MCP if you need specialized Architecture & Design tools running via a hosted cloud SSE transport. Choose Tentra MCP if your workspace requires Architecture & Design integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Mockit MCP when:
You need dedicated capabilities in the Architecture & Design domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: other (BYOK (Pay Provider Direct)).
Generate premium iOS mobile UI mockups (PNG + HTML) from a single text prompt. Pairs Claude (Opus 4.7 by default) with a Playwright headless renderer. Two backends — claude CLI (uses your Claude Code subscription) or Anthropic API. Stdio + HTTP transports, MIT.
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.
Tools & Capabilities Breakdown
Mockit MCP Tools (4)
generate_screen
Text brief → PNG + HTML. Optional `design_system` and `project` fields.
iterate_screen
Take a previous `screen_id` + `feedback` string, produce a new version.
list_screens
List screens, optionally filtered by project.
get_screen
Fetch metadata (or full HTML) for a specific screen.
Tentra MCP Tools (6)
Typed architecture diagrams from natural-language descriptions
Persistent code graph with symbol, import, and call-edge queries
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Mockit MCP is categorized under Architecture & Design and uses a remote streaming HTTP/SSE transport. In contrast, Tentra MCP belongs to Architecture & Design using local stdio subprocess. Select Mockit MCP when you need capabilities focused on architecture & design and Tentra MCP when you require tools for architecture & design.
