Its only credential is one basic-auth username and password with full access, and five critical advisories were published between March and September 2026, all fixed.\n\n**Paragon ActionKit + MCP.** Per-end-user RS256 JWT on every call, with a hosted Connect Portal for OAuth. No published prices and no self-serve paid plan.\n\n## Before you call either\n\n### Kestra\n\n1. Run 2.0.5 or 1.3.42 or later. Earlier builds carry unauthenticated remote code execution advisories fixed in 1.3.38 and 2.0.3\n2. Set `kestra.server.basic-auth` in the config file before first start. Without it the setup page is open to anyone who reaches the port\n3. Put the tenant in the path. Open-source instances use `main`, as in `/api/v1/main/executions/{namespace}/{id}`\n4. Send flow inputs as multipart form fields, and add `wait=true` to get the finished execution in the same call\n5. Keep port 8081 off any shared network. The management endpoints there skip the API's basic auth\n\n### Paragon ActionKit + MCP\n\n1. Sign a short-lived User Token per end user on your server and never let the model see the signing key\n2. Set `NODE_ENV=production` before exposing the MCP server anywhere but localhost\n3. Fetch the tool list once per session with `categories` set, and cache it\n4. Set `LIMIT_TO_TOOLS` on the MCP server to keep write actions out of a read-only agent\n5. Proxy API requests count as tasks, so prefer ActionKit tools for routine actions\n\n## Questions\n\n### Which is better for AI agents, Kestra or Paragon ActionKit + MCP?\n\nKestra scores 63.6 (B) on agent readiness against Paragon ActionKit + MCP's 47.5 (D), and leads in 6 of 7 scored categories. Paragon ActionKit + MCP leads on security \u0026 auth.\n\n### Do Kestra and Paragon ActionKit + MCP need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Kestra and Paragon ActionKit + MCP without installing anything?\n\nNo hosted endpoint is listed for Kestra. Paragon ActionKit + MCP has a hosted endpoint at https://actionkit.useparagon.com.\n\n### Are Kestra and Paragon ActionKit + MCP open source?\n\nKestra is open source (Apache-2.0 (open-source server and SDK repository). Enterprise Edition and Kestra Cloud are commercial). No open-source release is listed for Paragon ActionKit + MCP.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/kestra-vs-paragon.json, and with the fewest tokens: https://www.anchorterminal.com/compare/kestra-vs-paragon.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"kestra\", \"b\": \"paragon\"}`.
