## 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 58
- Schema & documentation, 82 against 63
- Agent ergonomics, 73 against 51
- Payments & pricing, 50 against 35
- Maintenance & community, 93 against 60

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

### Workato API + MCP (C)

Good for: Large companies that already run Workato and want agents inside its governance (roles, audit, per-user credentials).

Ahead on:
- Security & auth, 70 against 41

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Kestra loses 7 points for them

Watch for: No OpenAPI file and no official SDK on npm or PyPI

## 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.

**Workato API + MCP.** API client tokens scoped by role and project, with legacy full-access keys removed on 14 October 2025. No OpenAPI file and no official SDK on npm or PyPI.

## 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

### Workato API + MCP

1. Use the base URL for the workspace's data centre, and app.trial.workato.com for Free or Pro
2. Give the agent an API client whose role lists only the endpoints it needs. The MCP server exposes those as tools
3. Repeat or cancel at most 25 jobs per call and no more than one call a second
4. Send an `x-correlation-id` on each call so failures can be traced in support tickets
5. Every action step in a recipe is a task, so collapse loops before running at volume
