Track what you're seeing. Use it later.
Vantage is a personal signal store for AI-native work — a place to capture and query the things you notice across the web.
A post on X. A thread on LinkedIn. An insight from an article. A competitor move. Instead of losing it across tabs, screenshots, and notes, you save it — and use it later.
Your AI tools don't share memory.
Vantage fixes that.
Save signals once, and access them anywhere you have an MCP-compatible client — across Claude, Cursor, and other supported tools.
Example:
"Save this as a signal"
"What have I saved about pricing?"
"Show me signals from Lemkin"
Vantage is a simple way to keep track of what you're seeing — so your AI can actually use it later.
Sign up at vantage.cavendo.ai. Connect to Claude or another supported client. Start capturing.
Takes about 2 minutes. No install required.
npm install
npm run dev
# If 3020 is already in use, choose another port
PORT=YOUR_PORT npm run dev
# Generate your first API key
curl -X POST http://localhost:3020/api/auth/keys \
-H 'Content-Type: application/json' \
-d '{"name": "my-key"}'
The first API key can be created from localhost without auth. If you're bootstrapping a fresh remote deployment, set VANTAGE_BOOTSTRAP_TOKEN on the server and send the same value in the X-Vantage-Bootstrap-Token header on that first request.
The API key is returned as data.key in the JSON response.
Capture your first signal:
curl -X POST http://localhost:3020/api/signals \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer vtg_YOUR_KEY_HERE' \
-d '{
"signalType": "post",
"platform": "x",
"content": "Every SaaS company will need an agent layer within 18 months.",
"topics": ["AI Agents", "SaaS"],
"importance": "high"
}'
Vantage includes an MCP server with 13 tools for use with Claude, Claude Code, Cursor, or any MCP-compatible client.
If you want to use the bundled stdio MCP server directly, install its dependencies too:
cd mcp-server
npm install
cd ..
claude mcp add vantage --transport http "http://localhost:3020/mcp" --header "Authorization: Bearer vtg_YOUR_KEY"
For manual testing, note that /mcp is a streamable HTTP endpoint. MCP clients handle the response format automatically, but ad hoc curl calls need to be prepared for stream-oriented responses rather than a simple JSON-only request/response flow.
Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
