Overview

Description from the maker (original English)

Persistent memory for Claude Code and Cursor. Stop re-explaining your project every session.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Search & AI memory
  • You need to fill in: SUMA_API_KEY, Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: SUMA_API_KEY, Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "suma-memory": {
      "command": "npx",
      "args": [
        "-y",
        "suma-mcp-proxy"
      ],
      "env": {
        "SUMA_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http suma-memory https://sumapro.quadframe.work/mcp --header 'Authorization: your-value'

Or run it on your computer

claude mcp add suma-memory --env SUMA_API_KEY=your-value -- npx -y suma-mcp-proxy

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "suma-memory": {
      "url": "https://sumapro.quadframe.work/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "suma-memory": {
      "command": "npx",
      "args": [
        "-y",
        "suma-mcp-proxy"
      ],
      "env": {
        "SUMA_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "suma-memory": {
      "type": "http",
      "url": "https://sumapro.quadframe.work/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Or run it on your computer

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "suma-memory": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "suma-mcp-proxy"
      ],
      "env": {
        "SUMA_API_KEY": "your-value"
      }
    }
  }
}

Common questions

Is Suma Memory safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SUMA_API_KEY, Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.5.0) reached the registry 7 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

SUMA Memory MCP

Stop re-explaining your project to Claude every time you start a new chat.

Your repos now have permanent memory. SUMA gives any MCP-compatible AI client (Claude Code, Cursor, Devin) a persistent knowledge graph that remembers architectural decisions, bug root causes, and project rules — across sessions, across machines, across your entire team.


Install (30 seconds)

Get an API key at [sumapro.quadframe.work](https://sumapro.quadframe.work) — free tier available.

Add to your .mcp.json:

{

"mcpServers": { "suma-memory": { "url": "https://sumapro.quadframe.work/mcp", "headers": { "Authorization": "Bearer sk_live_your_key_here" } } } }

That's it. No local server. No Docker. No npm install. SUMA runs on Cloud Run — stateless, auto-scaled, always available.


Onboard Your Project (2 minutes)

After installing, run this once per repo to seed your permanent context:

suma_ingest(text="Project: [name]. Framework: [Next.js / Flask / etc].

Auth lives in: [path/to/auth.py]. Database: [PostgreSQL / SQLite / etc]. Rules never to break: [e.g. never store plaintext keys, all routes require org_id filter]. Deployment target: [Cloud Run / Vercel / etc].")

From this point forward, every new session inherits this context. You never explain it again.


How It Works

SUMA stores knowledge in a weighted graph. Every node has a gravity score across four dimensions:

  • Recency — newer facts surface first
  • Density — well-connected facts outrank isolated ones
  • Semantic similarity — vector distance to your query
  • Emotional weight — high-signal facts are reinforced over time

When you call suma_search, the K-WIL gravity algorithm traverses the graph and returns the highest-relevance context — not a flat list of chunks, not a raw embedding match, but the facts that actually matter for what you're doing right now.


Core Tools

ToolWhat it does
suma_pingHealth check — verify connection and API key
suma_ingestAdd knowledge to the graph (architecture decisions, bug fixes, rules)
suma_searchRetrieve relevant context by natural language query
suma_talkSearch + learn in one call — retrieves context and updates graph
suma_correctFix wrong information — supersedes original, queues replacement
suma_cleanRemove noise nodes that pollute search results

Three Use Cases

1. Persistent Architecture Memory
# After finalizing a decision:

suma_ingest(text="We chose REST over GraphQL. Root cause: GraphQL N+1 queries caused 3x latency on /search. Architect ruling Apr 10 2026.")

Next session, cold start — full context in one call:

suma_search(query="why did we switch to REST?")

→ Returns ruling with full context. No re-explaining.

2. Bug Root Cause Archive
# After fixing a hard bug:

suma_ingest(text="Cloud Run WebSocket bug: asyncio.run() in daemon thread killed by Cloud Run recycling. Fix: use asyncio.get_event_loop() instead. Never use asyncio.run() in long-lived Cloud Run services.")

Six months later, same error:

suma_search(query="asyncio cloud run daemon thread crash")

→ Root cause retrieved instantly. Hours saved.

3. Multi-Agent Knowledge Fusion

Architect, developer, and QA agents each write to SUMA using their own sessions. Their knowledge merges into one shared org graph. When QA asks "what did the architect decide about auth?", it retrieves the architect's ruling — zero explicit handoff required.


Enterprise Safety

Anti-flood protection: Each source machine is rate-limited to 5 ingests per 60 seconds. Runaway agent loops are broken gracefully — the 6th request returns {"status": "throttled"} without crashing or corrupting the graph.

Multi-tenant isolation: Every node is scoped to org_id at the database layer. Two organizations on the same Cloud Run instance cannot access each other's data — enforced by SQL, not application logic.

Immutable audit trail: suma_correct and suma_clean never delete data. Nodes are superseded and invisible to the API while preserved in storage for compliance.
