The hosted MCP server has seven tools behind OAuth and carries the user's permissions, and the main REST API has a public Swagger spec. No price, free plan or trial is published, and no 429 or idempotency guidance was found.\n\n**PostHog.** PostHog suits agents that need to query product data and manage flags or experiments. Its hosted MCP server has OAuth scopes, a read-only mode and a one-tool CLI mode over 1,096 tools. The status page shows 31 incidents in 90 days, four on analytics queries, and three security incidents were disclosed in the last year.\n\n## Before you call either\n\n### Optimizely Experimentation\n\n1. Connect to https://exp.mcp.opal.optimizely.com/mcp and complete OAuth in a browser. The session is time-limited, so expect to sign in again\n2. Call `exp_get_schemas` before `exp_execute_query`, and `exp_get_entity_templates` before `exp_manage_entity_lifecycle`, to learn the fields each entity needs\n3. Confirm the project and environment with the user before any create or update. Changes go to live Optimizely data\n4. Use the Visual Editor for Web Experimentation variation code. The MCP server does not write custom HTML, CSS or JavaScript\n5. Over REST, stay under 2 requests a second on `/flags/v1`, 100 a minute on `/v2` and 20 a minute on the results endpoints\n\n### PostHog\n\n1. Add `?readonly=true` or the `x-posthog-read-only` header to the MCP URL unless the task needs writes\n2. Pin the session with `x-posthog-project-id`, which also removes the `switch-project` and `switch-organization` tools\n3. In CLI mode run `info \u003ctool\u003e` once before `call`, and send one `exec` command per request\n4. On a 429 with code `api_queries_budget_exceeded`, wait for `Retry-After` and read `X-PostHog-Query-Budget-Remaining-Bytes`\n5. Page SQL results by keyset on `timestamp`. `OFFSET` returns 400 for personal API keys, and results cap at 50,000 rows\n\n## Questions\n\n### Which is better for AI agents, Optimizely Experimentation or PostHog?\n\nPostHog scores 68.4 (B) on agent readiness against Optimizely Experimentation's 62.6 (B), and leads in every scored category.\n\n### Do Optimizely Experimentation and PostHog need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Optimizely Experimentation and PostHog without installing anything?\n\nYes. Optimizely Experimentation has a hosted endpoint at https://exp.mcp.opal.optimizely.com/mcp and PostHog at https://us.posthog.com.\n\n### Are Optimizely Experimentation and PostHog open source?\n\nNo open-source release is listed for Optimizely Experimentation. PostHog is open source (MIT for the repository outside the `ee` directory, which has its own licence. PostHog Cloud is a hosted service under PostHog's terms).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/optimizely-vs-posthog.json, and with the fewest tokens: https://www.anchorterminal.com/compare/optimizely-vs-posthog.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"optimizely\", \"b\": \"posthog\"}`.
