Direct access to your Arcate product discovery workspace
Arcate MCP Connect — Server
The official MCP server for Arcate. Gives AI agents like Claude direct access to your product discovery workspace — reading signals, browsing your roadmap, and writing new feedback back in.
This is a remote HTTP server — no installation required. Configure a URL in your MCP client and connect instantly.
Requires an active Evidence subscription (€129/mo). API keys are generated in
/settings/integrationsinside your Arcate workspace.
Quick Start
1. Generate an API Key
Log in → Settings → Integrations → Generate API Key. Copy the key — shown only once.
2. Configure your MCP client
Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json):

"mcpServers": {
"arcate": {
"serverUrl": "https://eshuikffwhaxcvkzaewj.supabase.co/functions/v1/mcp-server",
"headers": {
"Authorization": "Bearer [YOUR API KEY]"
}
}
}
}
Cursor → Settings → MCP → Add Server → Type: HTTP → URL:
https://mcp.arcate.io
Header: Authorization: Bearer arc_YOUR_KEY_HERE
3. Restart your AI client and test

Batch ingest:
"Here are notes from 3 customer calls this week. Create signals for each and link them to relevant initiatives."
Security
- Keys are stored as SHA-256 hashes. The plaintext is shown only once and never stored.
- Every request is re-validated against
billing_statusanduse_mcpcapability. - All queries are hard-scoped to your
organization_id. Cross-tenant access is impossible. - MCP-created signals are tagged with
ingestion_source: mcpfor audit filtering in the UI.
Architecture
The server is deployed as a Supabase Edge Function implementing JSON-RPC 2.0 over HTTP (the MCP Streamable HTTP transport). A GET request to the server URL returns a human-readable info card — no MCP client needed to inspect it.
Source: src/ — TypeScript reference implementation
Deployment: Supabase Edge Functions (Deno)
