For developers
Give AI agents real access to your CRM
Kantos ships a Model Context Protocol (MCP) server with 60+ tools and a full REST API, so agents like Claude — and your own code — can query, create, and manage CRM data directly. API access is included on every paid plan.
MCP server (60+ tools)
A full Model Context Protocol server lets AI agents like Claude query, create, update, and manage your CRM via natural language — no custom integration code.
OAuth 2.0 + API keys
OAuth 2.1 with PKCE for agent authorization, plus hashed x-api-key credentials with prefixes, rate limits, and per-key audit events.
REST CRM API
Programmatic access to objects, fields, records, automations, and media — the same primitives the Kantos UI is built on.
Webhooks
Trigger outbound webhooks from automations with a retry queue and exponential backoff, or drive Kantos from inbound events.
REST API
# List records with your API key
curl https://kantos.ai/api/crm/record \
-H "x-api-key: $KANTOS_API_KEY"
# Create a record
curl -X POST https://kantos.ai/api/crm/record \
-H "x-api-key: $KANTOS_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "object": "lead", "data": { "name": "Acme Inc", "email": "hi@acme.com" } }'MCP server
// Point an MCP client (e.g. Claude Desktop) at the Kantos MCP server.
// Authorize once via OAuth; the agent then has 60+ CRM tools.
