Why the edge:
- Transparency & trust, Flagsmith +26: Flagsmith 77 (BSD-3-Clause for the core and the MCP server; the about page says most of the product is under that licence and some CI runs with private packages, so not every Cloud feature is in the open repository (25 of 30). The terms set Flagsmith as processor with 48-hour breach notice and EEA transfer rules, and the sub-processor list is dated 13 October 2025. The privacy policy dates from October 2023 and states no retention periods (16 of 30). The Gram-hosted MCP server was retired with a dated notice (30 June 2026), and three spec operations are marked deprecated, without a stated deprecation policy (10 of 20). The sub-processor list names providers and their countries (16 of 20). 25+16+10+16 = 67.); RudderStack MCP 51 (The server's source is closed; the repository's MIT licence covers only its docs and metadata. Terms in a master service agreement naming RudderStack, Inc. (15). Privacy policy read, retention given by purpose, not as periods (12 of 30). No deprecation policy for the MCP server (5 of 20). Subprocessors not found in the pages read (5 of 20). The MCP docs say live events, schemas, profile artifacts, transformation code and audit data stay within the workspace view. 15 + 12 + 5 + 5 = 37.)
- Reliability, Flagsmith +20: Flagsmith 65 (Graded on Flagsmith Cloud with the hosted lines. Statuspage at status.flagsmith.com with components for the Edge API, Admin API, dashboard and website (20). In the 90 days from 8 August, an Admin and SDK API outage on 28 October marked critical, posted at 21:56 UTC and resolved at 22:12 with no cause given, and a minor delay in processing flag changes on 10 September. The posted span of the outage is 16 minutes and its start isn't stated, so we read it as one serious incident under an hour (15 of 30). The Management API limit of 500 requests a minute is documented (15). No 429 handling, Retry-After or idempotency guidance was found in the docs (0). A public SLA commits to 99.95 per cent monthly uptime with service credits (10). The Management API is generally available, but the MCP docs call the server an early release, so half (5 of 10). 20+15+15+0+10+5 = 65.); RudderStack MCP 45 (Statuspage at status.rudderstack.com with regional components and none for MCP (15). Since August the history shows an EU ingestion issue, increased US latency, a Python transformations issue, free-tier processing delays and scheduled maintenance (20, minor incidents). No MCP rate limits found (0). No retry guidance for the MCP server found (0). No SLA found in the pages read (0). Not labelled beta (10). 15 + 20 + 0 + 0 + 0 + 10 = 45.)
- Payments & pricing, Flagsmith +10: Flagsmith 40 (No x402, MPP or L402 (0). Plan prices and the per-million overage are public without login, though the page gives two overage rates for Start-Up ($50 per million and $7 per 100,000) (20). A $0 Free plan with 50,000 requests a month and a free BSD-3-Clause self-hosted edition. The pricing page doesn't say whether a card is needed, but the Free plan has no charge and the self-hosted edition needs no account (20). A person signs up in a browser, then approves OAuth or creates a key (0). 0+20+20+0 = 40.); RudderStack MCP 30 (No machine payment protocol (0). Public plan prices with event allowances, nothing per call (10). Free plan with 250,000 events a month (20). A person signs up in a browser and approves OAuth (0). 0 + 10 + 20 + 0 = 30.)
