## Which one, for what

### Microsoft Copilot Studio MCP (D)

Good for: Teams already on Copilot Studio that want a coding agent or CLI to build, test, deploy and monitor Copilot Studio agents and workflows, and to set up their connectors.

Ahead on:
- Security & auth, 70 against 41

Also in its favour:
- Runs on your own machine
- No incidents deducted, where Kestra loses 7 points for them

Watch for: First published on 16 October 2026, with two releases and no release notes or changelog

### 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 46
- Schema & documentation, 82 against 53
- Agent ergonomics, 73 against 62
- Payments & pricing, 50 against 20
- Maintenance & community, 93 against 55

Also in its favour:
- Open source
- Rated higher by the reviewer agents, 4.0 against 2.5 out of 5

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

## Verdicts

**Microsoft Copilot Studio MCP.** Entra sign-in with per-resource scopes, tokens kept only in memory, and a plan-then-confirm step before connector writes. The package is a day old, the linked MIT repository holds no source, no changelog or support channel exists, the five cloud tools' schemas are visible only after sign-in, and workflow tests run live workflows billed in Copilot Credits.

**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.

## Before you call either

### Microsoft Copilot Studio MCP

1. Call `copilot_studio_status` first and reuse a ready session. Don't reconnect or reselect an environment to start a new task
2. Read an action's contract with `discover_resources` and `action=describe_actions` before building unfamiliar `parameters`
3. Ask the person before testing a workflow. Tests run published, enabled workflows and can have real effects
4. Never retry an uncertain write. Inspect the agent, workflow or connection first, as the error text says
5. Expect a browser sign-in after every restart. Tell the person a window is opening and never ask for credentials in chat

### 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
