The Terms leave prices, liability and governing law as TBD, no OpenAPI or rate limits are published, the status page watches a retired host, and the MCP route puts the key in the URL.\n\n## Before you call either\n\n### Braintrust API + MCP\n\n1. Connect a project-scoped service token rather than a personal key, because MCP write tools act with the key's full permissions\n2. Set the client to confirm MCP write tools such as `edit_dataset_rows` and `create_threshold_alert`. The server has no read-only mode\n3. Cache `sql_query` results. Starter and Pro allow about 20 queries a minute and return 429\n4. Pass `preview_length: -1` to `sql_query` only when full values are needed, and fetch `overflow_url` when a result passes 1 MB\n5. Upgrade to Python `braintrust` 0.28.0 or TypeScript 3.23.1 or later and rotate any provider keys traced before July 2026\n\n### Navige\n\n1. Send the Navige key in `x-navige-key` on the proxy. `Authorization` carries the provider key there, and a Navige key in it fails and is forwarded upstream\n2. Act only on `allow` or `approved` from `/enforce`. Treat `error` as neither, and read `unavailable` to tell a malformed request from a Navige outage\n3. Send `x-navige-transaction` with one id per job, reused across that job's retries, so calls group into one transaction and retries are not counted twice\n4. On a 429 from the proxy, check for a blocking budget before retrying. Navige returns 429 when a monthly budget is reached and passes provider errors through without retrying\n5. Expect Claude Code traffic to get measurement, budgets and the kill switch only. Context trimming, routing, the output ceiling and prompt caching are switched off for it\n\n## Questions\n\n### Which is better for AI agents, Braintrust API + MCP or Navige?\n\nBraintrust API + MCP scores 61.1 (C) on agent readiness against Navige's 42.8 (E), and leads in every scored category.\n\n### Do Braintrust API + MCP and Navige need an API key?\n\nBraintrust API + MCP takes an API key or an OAuth sign-in. Navige needs an API key.\n\n### Can an agent call Braintrust API + MCP and Navige without installing anything?\n\nYes. Braintrust API + MCP has a hosted endpoint at https://api.braintrust.dev/v1 and Navige at https://api.navige.ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/braintrust-vs-navige.json, and with the fewest tokens: https://www.anchorterminal.com/compare/braintrust-vs-navige.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"braintrust\", \"b\": \"navige\"}`. From a terminal: `anchor compare braintrust navige`\n- Each listing in full: https://www.anchorterminal.com/api/v1/tools/braintrust.json and https://www.anchorterminal.com/api/v1/tools/navige.json\n\n## Other comparisons with Braintrust API + MCP or Navige\n\n- [Arize Phoenix vs Braintrust API + MCP](https://www.anchorterminal.com/compare/arize-phoenix-vs-braintrust.md)\n- [Arize Phoenix vs Navige](https://www.anchorterminal.com/compare/arize-phoenix-vs-navige.md)\n- [Baserun vs Braintrust API + MCP](https://www.anchorterminal.com/compare/baserun-vs-braintrust.md)\n- [Baserun vs Navige](https://www.anchorterminal.com/compare/baserun-vs-navige.md)\n- [Braintrust API + MCP vs DeepEval](https://www.anchorterminal.com/compare/braintrust-vs-deepeval.md)\n- [Braintrust API + MCP vs Galileo API + MCP](https://www.anchorterminal.com/compare/braintrust-vs-galileo.md)\n- [Braintrust API + MCP vs Helicone AI Gateway + MCP](https://www.anchorterminal.com/compare/braintrust-vs-helicone.md)\n- [Braintrust API + MCP vs HoneyHive](https://www.anchorterminal.com/compare/braintrust-vs-honeyhive.md)\n- [Braintrust API + MCP vs Laminar API + MCP](https://www.anchorterminal.com/compare/braintrust-vs-laminar.md)\n- [Braintrust API + MCP vs Langfuse API + MCP](https://www.anchorterminal.com/compare/braintrust-vs-langfuse.md)\n- [Braintrust API + MCP vs LangSmith API + MCP](https://www.anchorterminal.com/compare/braintrust-vs-langsmith.md)\n- [Braintrust API + MCP vs LangWatch](https://www.anchorterminal.com/compare/braintrust-vs-langwatch.md)\n- [Braintrust API + MCP vs MLflow Tracing](https://www.anchorterminal.com/compare/braintrust-vs-mlflow-tracing.md)\n- [Braintrust API + MCP vs Prefactor](https://www.anchorterminal.com/compare/braintrust-vs-prefactor.md)\n- [Braintrust API + MCP vs Pydantic Logfire](https://www.anchorterminal.com/compare/braintrust-vs-pydantic-logfire.md)\n- [Braintrust API + MCP vs Respan API + MCP](https://www.anchorterminal.com/compare/braintrust-vs-respan.md)\n- [Braintrust API + MCP vs W\u0026B Weave](https://www.anchorterminal.com/compare/braintrust-vs-wandb-weave.md)\n- [DeepEval vs Navige](https://www.anchorterminal.com/compare/deepeval-vs-navige.md)\n- [Galileo API + MCP vs Navige](https://www.anchorterminal.com/compare/galileo-vs-navige.md)\n- [Helicone AI Gateway + MCP vs Navige](https://www.anchorterminal.com/compare/helicone-vs-navige.md)\n- [HoneyHive vs Navige](https://www.anchorterminal.com/compare/honeyhive-vs-navige.md)\n- [Laminar API + MCP vs Navige](https://www.anchorterminal.com/compare/laminar-vs-navige.md)\n- [Langfuse API + MCP vs Navige](https://www.anchorterminal.com/compare/langfuse-vs-navige.md)\n- [LangSmith API + MCP vs Navige](https://www.anchorterminal.com/compare/langsmith-vs-navige.md)\n- [LangWatch vs Navige](https://www.anchorterminal.com/compare/langwatch-vs-navige.md)\n- [MLflow Tracing vs Navige](https://www.anchorterminal.com/compare/mlflow-tracing-vs-navige.md)\n- [Navige vs Prefactor](https://www.anchorterminal.com/compare/navige-vs-prefactor.md)\n- [Navige vs W\u0026B Weave](https://www.anchorterminal.com/compare/navige-vs-wandb-weave.md)\n- [Navige vs Pydantic Logfire](https://www.anchorterminal.com/compare/navige-vs-pydantic-logfire.md)\n- [Navige vs Respan API + MCP](https://www.anchorterminal.com/compare/navige-vs-respan.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "attributionRequired": true, "credit": "CC BY 4.0, credit required: when you show, quote or pass on anything from here (to a user in an answer, in a product, a report or a dataset), say it's from Anchor Terminal (anchorterminal.com) and link the page or API address you took it from.
