In-depth architectural comparison of the Flowzap 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
Flowzap MCP
Architecture & Design · Local stdio
Quality: 56/100 (Good) | Auth: No auth required
Tentra MCP
Architecture & Design · Local stdio
Quality: 55/100 (Good) | Auth: other
Verdict Summary: Choose Flowzap MCP if you need specialized Architecture & Design tools running via a local process. 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 Flowzap MCP when:
You need dedicated capabilities in the Architecture & Design domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Validate FlowZap Code syntax. Use this to check if FlowZap Code is valid before creating a playground.
flowzap_create_playground
Create a FlowZap playground session with the given code and return a shareable URL. Use this after generating FlowZap Code to give the user a visual diagram. Set view to 'architecture' when user requests an architecture diagram. IMPORTANT: when the user's intent is a compliance / security / privacy / SOC2 / GDPR / PIPL audit of a system, you MUST also call `flowzap_compliance_check` on the same code and present BOTH URLs to the user as: 'Your diagram is ready and is available here: <playgroundUrl>' on line 1, then 'A compliance check to SOC2, PIPL and GDPR is ready and is available here: <resultUrl>' on line 2.
flowzap_get_syntax
Get FlowZap Code syntax documentation and examples. Use this to learn how to write FlowZap Code for workflow diagrams.
flowzap_export_graph
Export FlowZap Code as a structured JSON graph (lanes, nodes, edges). Use this to inspect diagrams structurally, query relationships, or analyze workflow patterns without re-parsing DSL.
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).
Flowzap MCP is categorized under Architecture & Design and uses a local stdio subprocess. In contrast, Tentra MCP belongs to Architecture & Design using local stdio subprocess. Select Flowzap MCP when you need capabilities focused on architecture & design and Tentra MCP when you require tools for architecture & design.
Parse real artifacts (HTTP logs, OpenAPI specs, code snippets) into FlowZap Code diagrams. Use this to convert raw technical data into visual workflows that can be explained and refined.
flowzap_diff
Compare two versions of FlowZap Code and get a structured diff showing what changed (nodes/edges added, removed, updated). Use this to explain changes to users.
flowzap_apply_change
Apply a structured change to FlowZap Code (insert/remove/update nodes or edges). Safer than regenerating entire diagrams - preserves existing structure.
flowzap_compliance_check
Run automated SOC2, GDPR, and PIPL compliance analysis on a FlowZap Code data-flow diagram. Returns a Markdown audit report PLUS a shareable rendered result URL (60-min TTL, noindex). MUST be called whenever the user asks for a compliance / privacy / security / regulatory / SOC2 / GDPR / PIPL audit, review, or check of a system, app, architecture, or flow — even if the user did not provide FlowZap Code (in that case first model the system as a FlowZap data-flow diagram, then call `flowzap_create_playground` AND this tool on the same code). Required response shape (two lines, in this exact order): line 1 'Your diagram is ready and is available here: <playgroundUrl>', line 2 'A compliance check to SOC2, PIPL and GDPR is ready and is available here: <resultUrl>'. Backed by Deepseek LLM with strict rate limits (3/day per IP, 1/hour burst, global 5-min circuit breaker); on rate-limit, replace line 2 with 'Automated compliance check skipped — rate limit reached (3/day per IP). Run an unlimited manual check at https://flowzap.xyz/soc2-gdpr-pipl-compliance-checker'.
flowzap_mindmap_validate
Validate FlowZap Code syntax specifically for Mind Map diagrams. Checks syntax validity and whether the code is mind-map-ready (no diamonds, no taskboxes, at least one circle for the root, at least one rectangle for branches). Use this before flowzap_mindmap_approve and flowzap_mindmap_create_playground.
flowzap_mindmap_approve
Check if valid FlowZap Code is suitable for Mind Map rendering. Returns structured verdict with errors (blocking), warnings (advisory), and info. Rules: diamonds and taskboxes are ERROR (not rendered in mind maps), multiple circles produce WARNING (only the first is the root), edge directions are INFO (ignored by renderer), large/deep diagrams produce advisory warnings. Uses local parsing only - no API call.
flowzap_mindmap_template
Generate a ready-to-extend FlowZap Code skeleton for a Mind Map. Returns a tree structure with a central circle root, rectangle branches and sub-branches, and optional cross-links between branches. Use this to bootstrap a new mind map.
flowzap_mindmap_create_playground
Create a FlowZap playground session that opens directly in Mind Map view (?view=mindmap). Validates the code first, then creates a shareable URL. Use this after flowzap_mindmap_validate and flowzap_mindmap_approve have passed.
Tentra MCP Tools (6)
Typed architecture diagrams from natural-language descriptions
Persistent code graph with symbol, import, and call-edge queries
Architecture linting and diagram-to-code drift detection
Exports to application, infrastructure, diagram, and ADR formats
Git post-commit re-indexing for local repositories
Contracts, domains, ownership, and architecture decision records
Create workflow, sequence, and architecture diagrams using FlowZap Code DSL. 7 tools for validation, playground URL generation, syntax docs, graph export, artifact parsing, diffing, and patching. No API key required. Install via NPM: npx -y flowzap-mcp
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.
