Which one, for what

Kestra B

Good for Engineering and data teams that want declarative YAML flows with scripts in any language, run on their own infrastructure.

Ahead on

  • Reliability, 89 against 63
  • Schema & documentation, 82 against 66
  • Agent ergonomics, 73 against 63
  • Payments & pricing, 50 against 30
  • Maintenance & community, 93 against 36

Also in its favour

  • Open source

Watch for

The open-source edition has one basic-auth username and password. API tokens, service accounts, RBAC and audit logs need Enterprise or Cloud

Make API + MCP C

Good for Teams who build in a visual editor and want an agent to run those scenarios as tools, cloud only.

Ahead on

  • Security & auth, 68 against 41

Also in its favour

  • A hosted endpoint, with nothing to install
  • Free to start without a card
  • No incidents deducted, where Kestra loses 7 points for them

Watch for

No published OpenAPI file and no official SDK

Verdicts

Kestra

Kestra's open-source edition has a 216-operation OpenAPI spec, Markdown docs for agents and weekly patch releases on two long-term support lines. 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.

Make API + MCP

Hosted MCP server with OAuth, and scenario run tools on the free plan. No published OpenAPI file and no official SDK.

Before you call either

Kestra

  1. 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
  2. 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
  3. Put the tenant in the path. Open-source instances use main, as in /api/v1/main/executions/{namespace}/{id}
  4. Send flow inputs as multipart form fields, and add wait=true to get the finished execution in the same call
  5. Keep port 8081 off any shared network. The management endpoints there skip the API's basic auth

Make API + MCP

  1. Find the organisation's zone first. It may be on make.com or make.celonis.com
  2. Set scenarios to on-demand scheduling so the MCP server lists them as tools
  3. Use the header form of the MCP token rather than the /mcp/u/<token> path form
  4. On a 429, wait a full minute. The limit resets per minute and no Retry-After is sent
  5. Check the code field on errors. IM002 means the token lacks rights, not that the resource is missing
