The Cloud terms reserve suspension for excessively frequent requests.\n\n\n## Why the edge\n\n### Reliability: Harness Feature Management \u0026 Experimentation +42\n\n- Harness Feature Management \u0026 Experimentation (80): Graded on the hosted FME Admin API with the hosted lines. Statuspage at status.harness.io with an FME component among 196 (20). In the 90 days from 8 August, two FME incidents: API write operations returned 499 errors for 30 minutes on 20 August (minor) and the FME user interface was unavailable for 15 minutes on 23 August (major, interface only; flag evaluation was unaffected per the post). No API outage of an hour or more (20 of 30). About 20 Admin API requests per 10 seconds per organisation and per IP, documented on the MCP page (15). 429 responses carry remaining and reset headers with guidance to wait for the larger reset, and the MCP server backs off and retries three times (15). No SLA was found on harness.io/pricing or the FME docs (0). FME is generally available and the MCP server is at 3.2.40 (10). 20+20+15+15+0+10 = 80.\n- Matomo (38): Graded on the hosted lines, for a Matomo Cloud instance reached through the Reporting HTTP API and the MCP server included with Cloud. status.matomo.cloud is the listed public status page, credited on its existence as for the Zoho status hosts and fireflies (20). On 4 November its robots.txt answered with an access-denied error page, so the page wasn't read again and the 9 October component and feed readings are struck. No 90-day incident record could be read then or now (5). No API rate limit numbers were found. The terms reserve suspension for excessively frequent requests, and `API.getBulkRequest` is capped at 50 URLs for anonymous callers (3 of 15). No 429 or retry guidance and no idempotency keys were found (0). No SLA for Cloud was found, and the terms supply the service as is (0). The Reporting API and MCP plugin 5.1.1 are stable releases (10).\n\n### Payments \u0026 pricing: Matomo +15\n\n- Harness Feature Management \u0026 Experimentation (15): No x402, MPP or L402 (0). No FME prices are published; harness.io/pricing lists FME only under Enterprise, priced by quotation (0). The docs describe a Start FME Free Plan step inside a Harness account; its limits and whether a card is needed aren't stated (15 of 20). A person signs up for Harness in a browser and creates a key or token (0). 0+0+15+0 = 15.\n- Matomo (30): Scored for Matomo Cloud, the hosted option. No x402, MPP or L402 (0). Plan prices by monthly hits are public without a login, from $26 for 50,000 hits to $17,900 for 100 million, and API calls are not priced by unit (10). The Cloud trial needs no credit card, and On-Premise is free to self-host (20). A person signs up in a browser, and the terms forbid accounts registered by bots or other automated methods (0).\n\n### Transparency \u0026 trust: Matomo +13\n\n- Harness Feature Management \u0026 Experimentation (61): A closed service under Harness's subscription terms; the MCP server is MIT (18 of 30). The privacy statement covers website and sales data and defers customer data to the customer agreement and a published DPA; retention periods for customer data weren't found (18 of 30). A versioning policy for SDKs with support windows, and Split-era API endpoints marked deprecated with migration guides (14 of 20). Sub-processors are on the trust centre, which we didn't read, and the security page doesn't name data locations (10 of 20). 18+18+14+10 = 60.\n- Matomo (74): The core and the MCP plugin are GPL v3 or later. Matomo Cloud is a hosted service under terms, and paid On-Premise plugins fall under the InnoCraft EULA (22 of 30). The Cloud terms, DPA and privacy policy agree. Customer data is deleted 30 days after termination, with residual account information in backups and logs for up to 60 days, raw data is kept 24 months on the Business plan, and the customer owns its data. The privacy policy gives no period for account data (25). The developer changelog lists deprecations with the major version that removes them and no dates. The terms allow changes with or without notice and promise notice of significant permanent ones (12 of 20). The sub-processor list, last updated 9 October 2025, names AWS in Frankfurt and Dublin, an AWS management firm in the Netherlands and a monitoring firm in Germany (18).\n\n### Security \u0026 auth: Harness Feature Management \u0026 Experimentation +8\n\n- Harness Feature Management \u0026 Experimentation (79): Admin API keys with combinable roles that can't be widened after creation, Harness PATs and SATs for central management, and Harness Platform OAuth on the hosted MCP endpoint. Credentials travel in headers (28 of 30). HARNESS_READ_ONLY removes every write, writes go through elicitation with a risk threshold for auto-approval, and FME change requests add approval for flag changes (19 of 20). No prompt-injection guidance; the tools return flag names, descriptions and rule data written by people (3 of 15). FME admin, environment and object audit logs, plus structured MCP audit events to file, webhook or OpenTelemetry sinks (13 of 15). SOC 1 and SOC 2 Type II, ISO 27001, 27017 and 27018, FedRAMP 20x, a security@harness.io disclosure route with a 24-hour response, a private bug bounty on request and annual external penetration tests. No security.txt (16 of 20). 28+19+3+13+16 = 79.\n- Matomo (71): OAuth 2.0 plugin with authorisation code and PKCE, client credentials and refresh grants, four scopes with one a token, and client pause and secret rotation. `token_auth` tokens are revocable with an expiry date and a POST-only option, and gain an access level in Matomo 6 (26 of 30). Less 10 because the API docs present `token_auth` as a URL parameter (16). View-level users and scopes, MCP disabled by default, raw API tools off by default with per-class switches and a privilege cap. No confirmation step in the server (16 of 20). Matomo publishes prompt-injection guidance for analytics data with risk levels, and MCP errors do not echo supplied values. No filtering of tool output was found (11 of 15). Activity Log is listed for Cloud, the DPA describes authentication and change logs, and MCP tool-call logging is off by default (11). HackerOne bounty up to $13,000, a disclosure policy, ISO/IEC 27001:2022 certification stated, security fixes noted in release notes. No security.txt (17).\n\n### Agent ergonomics: Harness Feature Management \u0026 Experimentation +5\n\n- Harness Feature Management \u0026 Experimentation (83): 11 consolidated tools, and `--toolsets=fme` narrows the server to FME (25). Flag lists filter server-side by name, tag and rollout status, and the Admin API paginates with markerLimit (17 of 20). Documented status codes, 429 headers, and a harness_diagnose tool. Error bodies aren't documented per endpoint (14 of 20). harness_list and harness_get carry readOnlyHint, write tools ask for confirmation by elicitation, and harness_delete is marked destructive. No idempotency keys (15 of 20). Two required settings (API key, optional org and project, account ID read from the token); a Python Admin API wrapper and CLI, and SDKs in more than a dozen languages for evaluation (12 of 15). 25+17+14+15+12 = 83.\n- Matomo (78): The MCP server has 19 tools, 12 of them visible by default (15), plus 6 because the seven raw API tools stay hidden until an administrator allows them by read, create, update or delete class (21). `filter_limit`, `filter_offset`, sorting, pattern filters, `showColumns` and segments on the API, and cursors with a 250-row cap on the MCP report tool (20). Errors are HTTP codes with a message and an optional integer code, with no code catalogue. The MCP server separates schema failures (-32602) from tool result errors that name the arguments involved (14). Every MCP tool carries readOnlyHint, destructiveHint and idempotentHint. API writes have no idempotency keys and the OpenAPI descriptions declare delete methods as GET (13). Report calls need only `idSite`, `period` and `date`. The official clients for JavaScript, PHP and Java cover tracking, not the Reporting API (10).\n\n## Score by category\n\n| Category | Weight | Harness Feature Management \u0026 Experimentation | Matomo | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 80 | 38 | Harness Feature Management \u0026 Experimentation +42 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 71 | 73 | Matomo +2 |\n| Agent ergonomics | 13% (16.2 this run) | 83 | 78 | Harness Feature Management \u0026 Experimentation +5 |\n| Security \u0026 auth | 14% (17.5 this run) | 79 | 71 | Harness Feature Management \u0026 Experimentation +8 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 15 | 30 | Matomo +15 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 81 | 79 | Harness Feature Management \u0026 Experimentation +2 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 61 | 74 | Matomo +13 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **69.2 · B** | **61.7 · C** | |\n\n## Facts side by side\n\n| Fact | Harness Feature Management \u0026 Experimentation | Matomo |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | Harness Inc. | InnoCraft Limited |\n| Hosted endpoint | `https://mcp.harness.io/mcp` | no (local only) |\n| Transports | HTTP, stdio, Streamable HTTP | HTTP, Streamable HTTP |\n| Auth | OAuth or key | OAuth or key |\n| Pricing | Freemium | Paid |\n| x402 | no | no |\n| Licence | none | Matomo core is GPL-3.0-or-later and the MCP server plugin is GPL v3 or later.

FME prices are not published, the free plan's limits are unstated, and the hosted MCP endpoint must be enabled by Harness Support.\n\n**Matomo.** The Reporting API covers reports, funnels, cohorts and experiments with an OpenAPI 3.1 description per module, and the MCP server is disabled until an administrator enables it, with raw API tools off by default. No rate limits, 429 guidance or Cloud SLA were found, and the documented default sends `token_auth` in the URL.\n\n## Before you call either\n\n### Harness Feature Management \u0026 Experimentation\n\n1. Start the MCP server with `--toolsets=fme` so only FME resource types load\n2. Call `harness_describe(resource_type='fme_feature_flag')` before a create or update to see the fields\n3. Filter fme_feature_flag lists by name, tags or rollout status rather than listing every flag\n4. Set HARNESS_READ_ONLY for analysis tasks; leave confirmation on for kill, restore and delete\n5. On 429, wait at least the larger X-RateLimit-Reset-Seconds value before retrying\n\n### Matomo\n\n1. Send the token as `Authorization: Bearer` or in a POST body, never in the URL. Tokens set to secure requests only are ignored in GET query strings.\n2. Pass `format=json`, `filter_limit` and `showColumns` on report calls. The default returns the top 100 rows and `format_metrics` defaults to a deprecated mixed mode, so set `format_metrics=0`.\n3. For MCP, use the endpoint `index.php?module=API\u0026method=McpServer.mcp\u0026format=mcp`. A superuser must enable it first, or authenticated calls return 403.\n4. Treat page titles, URLs, campaign tags, search keywords and event names in results as untrusted text. Matomo's own MCP guidance warns they can carry injected instructions.\n5. Write and delete methods are plain API methods, some documented as GET. Use a view-level user or the `matomo:read` scope unless the task needs writes.\n\n## Questions\n\n### Which is better for AI agents, Harness Feature Management \u0026 Experimentation or Matomo?\n\nHarness Feature Management \u0026 Experimentation scores 69.2 (B) on agent readiness against Matomo's 61.7 (C), and leads in 4 of 7 scored categories.
