## Which one, for what

### Amplitude (B)

Good for: A team already on Amplitude that wants an agent to query charts, funnels, retention and experiment results, edit dashboards and manage the tracking plan under its own permissions.

Ahead on:
- Security & auth, 74 against 66
- Payments & pricing, 30 against 0
- Maintenance & community, 83 against 78

Also in its favour:
- Free to start without a card

Watch for: No rate limit for the MCP server or the Developer API was found in the reviewed documentation

### Optimizely Experimentation (B)

Good for: An agent working for an existing Optimizely customer that lists and creates flags, experiments and audiences, reads experiment results and writes SDK integration code.

Ahead on:
- Reliability, 73 against 60

Watch for: No price is published. The plans page says every plan is individually packaged and leads to a demo request

## Verdicts

**Amplitude.** The remote MCP server covers queries, funnels, retention, experiments and flags under OAuth with PKCE, read and write scopes and per-project role actions, and the Free plan needs no card. No MCP rate limits or SLA were found, and status.amplitude.com records a critical outage of the UI, MCP and REST APIs on 13 July 2026.

**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.

## Before you call either

### Amplitude

1. Connect to https://mcp.amplitude.com/mcp, or https://mcp.eu.amplitude.com/mcp for EU projects. The client must support streaming HTTP and OAuth, since API keys aren't accepted
2. Append `?discovery=progressive` to load tool schemas on demand, then call `get_amplitude_context` first to pick the project and read its AI context
3. Ask an admin for a role with only Use MCP (read) on the projects you need. Tools stay listed and fail at call time when the role lacks the action
4. Send events through the HTTP V2 API with an `insert_id` on each one. On 429, pause that user or device for 30 seconds before retrying
5. Budget Dashboard REST queries by cost (days times conditions times chart cost), within 108,000 an hour and 5 concurrent requests per project

### Optimizely Experimentation

1. 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
2. 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
3. Confirm the project and environment with the user before any create or update. Changes go to live Optimizely data
4. Use the Visual Editor for Web Experimentation variation code. The MCP server does not write custom HTML, CSS or JavaScript
5. Over REST, stay under 2 requests a second on `/flags/v1`, 100 a minute on `/v2` and 20 a minute on the results endpoints
