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 The server lists 141 tools, numeric rate limits are unpublished, and the web application was unavailable for over an hour on 10 July 2026.\n\n**Optimizely Experimentation.** Optimizely Experimentation suits agents working for an existing customer that manage flags and experiments and read results. 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## Before you call either\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### 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## Questions\n\n### Which is better for AI agents, LaunchDarkly or Optimizely Experimentation?\n\nLaunchDarkly scores 69.2 (B) on agent readiness against Optimizely Experimentation's 62.6 (B), and leads in 5 of 7 scored categories. Optimizely Experimentation leads on reliability.\n\n### Do LaunchDarkly and Optimizely Experimentation need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call LaunchDarkly and Optimizely Experimentation without installing anything?\n\nYes.
