          "-3: 2025-11-24. Malicious versions of posthog-node, posthog-js and six other npm packages were published with a stolen token after an attacker took CI secrets through a pull request workflow. PostHog removed them in about five hours and published a post-mortem on 26 November 2025, so the deduction is reduced (https://posthog.com/blog/nov-24-shai-hulud-attack-post-mortem).",

PostHog says no customer data was accessed and the credentials were rotated. Fixed and documented (https://posthog.com/handbook/company/security-advisories).",

The free plan needs no card. The API tools pass paths and JSON bodies through without validation, every key is limited to 60 requests a minute, and audit logs are Enterprise only.\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### GrowthBook\n\n1. Connect to https://mcp.growthbook.io/mcp and complete OAuth in a browser. Use https://mcp.growthbook.io/mcp/api for the two API tools alone\n2. Call `growthbook_list_skills` and `growthbook_read_skill` before writing. The API tools don't validate payloads, so use the paths the skill names\n3. Stay under 60 requests a minute per key. On 429 wait for the `RateLimit-Reset` seconds before retrying\n4. List calls return 10 items by default. Pass `limit` up to 100 and `offset` to page\n5. A 422 is a soft warning. Resubmit with `?ignoreWarnings=true` only after reading the message\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, GrowthBook or PostHog?\n\nGrowthBook scores 70.1 (BB) on agent readiness against PostHog's 68.4 (B), and leads in 1 of 7 scored categories. PostHog leads on schema \u0026 documentation, security \u0026 auth and transparency \u0026 trust.\n\n### Do GrowthBook and PostHog need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call GrowthBook and PostHog without installing anything?\n\nYes. GrowthBook has a hosted endpoint at https://mcp.growthbook.io/mcp and PostHog at https://us.posthog.com.\n\n### Are GrowthBook and PostHog open source?\n\nYes. GrowthBook is open source (MIT for the core and for the MCP server. Three enterprise directories in the main repository are under GrowthBook's enterprise licence. GrowthBook Cloud is a hosted service under the Customer Agreement). PostHog is open source (MIT for the repository outside the `ee` directory, which has its own licence.
