Connect Allivista

Four tools. Three of them only read; remember writes to your private, passphrase-encrypted store that we cannot read.

1. Download the extension: ⬇ allivista.mcpbone-click Desktop extension
2. Open Claude Desktop → Settings → Extensions and drag allivista.mcpb in (or double-click it).
3. Paste your Pro API key and memory passphrase into the fields.
4. Done — discover, verify, recall, remember appear in Claude.

No Python or JSON needed — everything (server + dependencies) is bundled and runs locally on your machine.

Comfortable with a terminal and a config file? Read on. Otherwise use Claude Desktop above — same connector, zero setup.

Prerequisites

• Python 3.10+ on your PATH.
• Install the runtime deps: pip install mcp httpx cryptography
• Download the server: ⬇ allivista-mcp.zipstdio server source (~30 KB) and unzip it somewhere stable.

Add it to .mcp.json (project root) or ~/.claude.json

{
  "mcpServers": {
    "allivista": {
      "command": "python",
      "args": ["/path/to/allivista-mcp/api/mcp_server.py"],
      "env": {
        "ALLIVISTA_API_KEY": "alv_your_pro_key",
        "ALLIVISTA_MEMORY_PASSPHRASE": "your-memory-passphrase",
        "ALLIVISTA_BASE_URL": "https://api.allivista.com"
      }
    }
  }
}

Restart Claude Code so it launches the server. On macOS/Linux use python3 and a full path like /Users/you/allivista-mcp/api/mcp_server.py.

Same prerequisites as Claude Code (Python 3.10+, pip install mcp httpx cryptography, the unzipped server). Add Allivista in Cursor → Settings → MCP → Add new server, or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "allivista": {
      "command": "python",
      "args": ["/path/to/allivista-mcp/api/mcp_server.py"],
      "env": {
        "ALLIVISTA_API_KEY": "alv_your_pro_key",
        "ALLIVISTA_MEMORY_PASSPHRASE": "your-memory-passphrase",
        "ALLIVISTA_BASE_URL": "https://api.allivista.com"
      }
    }
  }
}

Reload Cursor; the green dot next to allivista means it connected.

Allivista is a standard stdio MCP server. Point any client at:

# command + args
python /path/to/allivista-mcp/api/mcp_server.py

# environment
ALLIVISTA_API_KEY=alv_your_pro_key
ALLIVISTA_MEMORY_PASSPHRASE=your-memory-passphrase   # optional (memory)
ALLIVISTA_BASE_URL=https://api.allivista.com

The server speaks MCP over stdin/stdout and proxies to api.allivista.com over TLS using your key.

Discover hidden links — "Use Allivista to discover hidden bridges for Parkinson's disease."
→ concepts the literature connects only indirectly, plus a narration. Tip: pass comma-separated variants, e.g. alzheimer,alzheimers,dementia.

Fact-check a relationship — "With Allivista, verify whether amyloid-beta drives Alzheimer's."
→ a verdict (supported_direct … unsupported) + the bridging concepts — a hallucination check before you cite a link.

Remember something — "Remember this in Allivista: <your note>."
→ stored verbatim, encrypted on your device. Give it a title so you can overwrite it later.

Recall it later — "Recall from my Allivista memory: Project Halcyon vendor quote."
→ the exact passage + which note it came from. Search a distinctive literal phrase — recall is exact, not fuzzy.

Allivista runs on GeoLang — a language that encodes meaning as geometry: concepts as points in a structured space, related by their typed faces and co-occurrence bonds. The cortex (discover/verify) reads that structure directly — no embeddings. Your memory is a per-user keyed GeoLang dialect: words become opaque structural ids your machine can search but our servers can't read — verbatim and zero-knowledge at once. The cortex and memory are just two dialects; there's more. What is GeoLang? →
