What your AI can do with Purple8 — AI-Native Application Backend
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “rag.query”: Flat Vector RAG — retrieves the most relevant graph nodes by pure vector similarity (HNSW + RRF fusion + keyword fallback), then calls the c.”
“Use “rag.hybrid_query”: Hybrid Graph-Vector RAG — fuses vector similarity AND graph structural signals at every stage: dual-seed fusion (Weighted RRF over vector ra.”
“Use “rag.profile_collection”: Analyse the graph topology and return recommended RAG retrieval settings. Profiles node count, edge density, degree distribution, edge-type.”
“Use “graph.query”: Execute a Cypher query against the Purple8 knowledge graph and return matching records. Use for nodes, edges, paths, or aggregated data.”
How secure is the Purple8 — AI-Native Application Backend MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Purple8 — AI-Native Application Backend holds up.
Official endpoint
Operated by Purple8 — AI-Native Application Backend (purple8.ai) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Purple8 — AI-Native Application Backend adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Purple8 — AI-Native Application Backend
Choose Purple8 — AI-Native Application Backend in the gate directory. No sign-in needed.
Use it anywhere
Purple8 — AI-Native Application Backend's tools are live in every AI client you've connected — with rules and logging built in.

The actual tools Purple8 — AI-Native Application Backend exposes
Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.
rag.query — Flat Vector RAG — retrieves the most relevant graph nodes by pure vector similarity (HNSW + RRF fusion + keyword fallback), then calls the c
rag.hybrid_query — Hybrid Graph-Vector RAG — fuses vector similarity AND graph structural signals at every stage: dual-seed fusion (Weighted RRF over vector ra
rag.profile_collection — Analyse the graph topology and return recommended RAG retrieval settings. Profiles node count, edge density, degree distribution, edge-type
graph.query — Execute a Cypher query against the Purple8 knowledge graph and return matching records. Use for nodes, edges, paths, or aggregated data.
graph.vector_search — Find the k nearest nodes to a natural-language query using the HNSW vector index.
graph.hybrid_search — Combine vector similarity with graph traversal for highest-recall retrieval. Best when graph structure matters.
graph.traverse — Walk the graph from a starting node following edges up to a given depth.
graph.add_node — Insert a new node into the graph (accepts `type`, `label`, or `node_type`). Requires editor role.

The Purple8 — AI-Native Application Backend MCP server at a glance
https://purple8-graph-sandbox.fly.dev/mcp?profile=starterQuestions, answered
Is there an official Purple8 — AI-Native Application Backend MCP server?
Yes — Purple8 — AI-Native Application Backend operates its own remote MCP server at purple8-graph-sandbox.fly.dev. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Purple8 — AI-Native Application Backend to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Purple8 — AI-Native Application Backend in the directory. No account or sign-in is needed. From then on, Purple8 — AI-Native Application Backend's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Purple8 — AI-Native Application Backend runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Purple8 — AI-Native Application Backend MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Purple8 — AI-Native Application Backend in minutes. No credit card required.
