Verdicts

guilds.run

A self-hosted multi-agent system that records each run's prompt, tool calls and memory changes, with per-agent models and tools and no telemetry by default. Public since 9 October 2026, it has no tagged release or published package, its own security register lists 13 open issues, and the site's terms and privacy links return 404.

OpenAI Agents SDK

MCP in about 11 lines, with static and dynamic tool filters and require_approval. Tracing on by default, with model and tool content, sent to OpenAI.

Before you call either

guilds.run

  1. Keep the box on loopback or behind an authenticating proxy with AUTH_MODE=trusted-header. The default mode does not authenticate
  2. Put agents that hold different secrets or GitHub tokens on different machines. Agents on one machine can read each other's homes and tokens
  3. Back up the .env file written by ./setup.sh. It holds the only copy of the key that encrypts stored credentials
  4. Set a spend limit at your model provider. guilds.run sets no spend cap, and max_tool_calls defaults to 50 per run
  5. Pin a commit of main when you deploy. There are no tagged releases or versioned images yet

OpenAI Agents SDK

  1. Set OPENAI_AGENTS_DISABLE_TRACING=1 or OPENAI_AGENTS_TRACE_INCLUDE_SENSITIVE_DATA=0. Through 0.23.1, RunConfig(tracing_disabled=True) doesn't stop spans inside your own trace() block
  2. Pin to a minor version. Each 0.Y can break
  3. Set require_approval on MCP servers that write
  4. Name the model explicitly. The default changed in 0.20.0
  5. Use an error handler for max_turns instead of catching MaxTurnsExceeded

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.
