The official MCP server filters its 209 tools by edition, plugin and permission and has per-category read-only settings. No status page, OpenAPI document or published API rate limit was found, and the Flex trial needs a credit card.\n\n**LaunchDarkly.** LaunchDarkly suits agents that manage feature flags, rollouts and experiments. The hosted MCP server uses OAuth with dynamic client registration and marks its tools read-only or destructive, and the Developer plan is free without a card. The server lists 141 tools, numeric rate limits are unpublished, and the web application was unavailable for over an hour on 10 July 2026.\n\n## Before you call either\n\n### Countly\n\n1. Create a dedicated token in the Token Manager, limited to the apps and endpoints the task needs, and send it in the `countly-token` header, not the URL\n2. Set `COUNTLY_TOOLS_ALL=R` unless the task needs writes. The token's own permissions still apply and the stricter of the two wins\n3. Call `apps_list` first. Most tools need `app_id` or an exact `app_name`\n4. Check `get_version` for the detected edition before planning funnel, retention or cohort queries, which need Enterprise plugins\n5. Set `ENABLE_ANALYTICS=false` to stop usage reports to stats.count.ly, and prefer the stdio server to mcp.count.ly so the server URL and token stay local\n\n### LaunchDarkly\n\n1. Connect to https://mcp.launchdarkly.com/mcp/launchdarkly over streamable HTTP with OAuth. On the EU or federal instance run the local `@launchdarkly/mcp-server` with `--server-url`\n2. Authorise with a Reader role or the `reader` scope unless the task writes. A 403 after consent means the member's role lacks access\n3. Send `LD-API-Version: 20240415` on every REST call, and `LD-API-Version: beta` for beta resources, which answer 403 without it\n4. Read `X-Ratelimit-Global-Remaining`, `X-Ratelimit-Route-Remaining` and `X-Ratelimit-Reset` on each response, and wait `Retry-After` seconds on an IP limit\n5. Send `Content-Type: application/json; domain-model=launchdarkly.semanticpatch` for semantic patches, or the body is read as JSON patch and answers 400\n\n## Questions\n\n### Which is better for AI agents, Countly or LaunchDarkly?\n\nLaunchDarkly scores 69.2 (B) on agent readiness against Countly's 54.8 (C), and leads in every scored category.\n\n### Do Countly and LaunchDarkly need an API key?\n\nCountly needs an API key. LaunchDarkly takes an API key or an OAuth sign-in.\n\n### Can an agent call Countly and LaunchDarkly without installing anything?\n\nYes. Countly has a hosted endpoint at https://mcp.count.ly/mcp and LaunchDarkly at https://mcp.launchdarkly.com/mcp/launchdarkly.\n\n### Are Countly and LaunchDarkly open source?\n\nCountly is open source (Countly Lite is AGPL-3.0 with added branding terms under Section 7. Enterprise plugins are proprietary. Flex is a hosted service under Countly's terms. The MCP server is MIT). No open-source release is listed for LaunchDarkly.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/countly-vs-launchdarkly.json, and with the fewest tokens: https://www.anchorterminal.com/compare/countly-vs-launchdarkly.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"countly\", \"b\": \"launchdarkly\"}`.
