Which one, for what

Docker Agent BB

Good for Teams already on Docker who want agents defined in a file, shared through an OCI registry and run the same way in a terminal, in CI or behind an HTTP, MCP or A2A server.

Ahead on

  • Reliability, 88 against 83
  • Maintenance & community, 96 against 90

Also in its favour

  • Free to start without a card

Watch for

Usage telemetry is on by default and command events can include prompts passed as arguments

Pydantic AI A

Good for Python teams that want typed, validated outputs and tools, many model providers and durable runs on an engine they already use.

Ahead on

  • Schema & documentation, 100 against 90
  • Agent ergonomics, 95 against 81
  • Security & auth, 95 against 70
  • Transparency & trust, 85 against 80

Verdicts

Docker Agent

An agent with an MCP server is eight lines of YAML, and the same file runs in a terminal, headless, or as an HTTP, MCP or A2A server. Usage telemetry is on by default and can carry prompts passed as command arguments, and two high-severity approval bypasses were fixed in August and September 2026.

Pydantic AI

Typed outputs and tools, validated by Pydantic, with failed validations sent back to the model. Python only.

Before you call either

Docker Agent

  1. Set TELEMETRY_ENABLED=false before run or exec with a prompt on the command line. Telemetry is on by default and sends positional arguments
  2. For unattended runs pass --safety restricted with an allow-list, or --sandbox. Without a policy, --exec rejects every tool call that needs approval
  3. Set max_iterations and a budget block in the config. Both are unlimited by default
  4. Run 1.130.0 or later. Earlier versions ran shell commands embedded in local skills, and A2A sessions before 1.126.0 skipped tool approval
  5. Review runtime.safety in any config pulled from a registry or URL. An author default of autonomous runs every tool call unprompted

Pydantic AI

  1. Define the output type first. Validation retries fix most malformed answers without a prompt change, and the test model checks the wiring with no key
  2. Use streamable HTTP for MCP, since SSE is deprecated. Call .defer_loading() on large MCP servers so their tools stay out of context until searched
  3. Set usage limits on every run that calls paid models
  4. Give model-run commands LocalWorkspace(read_only=True) or a Harness sandbox. A plain LocalWorkspace runs them on your machine as you
  5. Stay on a current release. 2026 advisories hit URL downloads, the cloud-metadata blocklist and the local web chat UI (Agent.to_web(), clai web)

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
