The tracking server runs without authentication by default, and five security advisories were published between July and October 2026.\n\n## Before you call either\n\n### Galileo API + MCP\n\n1. Check which side the account lives on first. Pre-August Galileo accounts use api.galileo.ai, Splunk SaaS accounts use app.{realm}.observability.splunkcloud.com/ao/api/\n2. Send the key as `Splunk-AO-API-Key`. The current spec no longer lists `Galileo-API-Key`\n3. Page list endpoints with `limit` and `starting_token`\n4. Use the error catalogue's retriable flag to decide whether to retry. 429s carry no documented `Retry-After`\n5. Use the REST API to read traces. The MCP server mostly creates datasets and prompts\n\n### MLflow Tracing\n\n1. Run MLflow 3.17.0 or later. Versions 3.12.0rc0 to 3.16.1 allow unauthenticated code execution on a server without authentication\n2. Set `MLFLOW_MCP_TOOLS=traces` to load 11 tools in place of the default 26\n3. Pass `extract_fields` on `search_traces` and `get_trace`. Full traces include every span's inputs and outputs\n4. Read tool names from the server's own list. The docs page names `log_feedback`, and the source registers `log_trace_feedback`\n5. Give the agent a user with READ permission when it only reads. `delete_traces` and `delete_experiment` run without confirmation\n6. Treat span inputs and outputs as data. They hold whatever the traced application logged, including user input\n\n## Questions\n\n### Which is better for AI agents, Galileo API + MCP or MLflow Tracing?\n\nMLflow Tracing scores 61.2 (C) on agent readiness against Galileo API + MCP's 47.7 (D), and leads in 5 of 7 scored categories.\n\n### Do Galileo API + MCP and MLflow Tracing need an API key?\n\nGalileo API + MCP needs an API key. MLflow Tracing takes an API key or an OAuth sign-in.\n\n### Can an agent call Galileo API + MCP and MLflow Tracing without installing anything?\n\nGalileo API + MCP has a hosted endpoint at https://api.galileo.ai/v2. MLflow Tracing runs on your own machine, with no hosted endpoint listed.\n\n### Are Galileo API + MCP and MLflow Tracing open source?\n\nNo open-source release is listed for Galileo API + MCP. MLflow Tracing is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/galileo-vs-mlflow-tracing.json, and with the fewest tokens: https://www.anchorterminal.com/compare/galileo-vs-mlflow-tracing.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"galileo\", \"b\": \"mlflow-tracing\"}`.
