Why the edge:
- Security & auth, Overmind +37: Galileo API + MCP 33 (API key in a header (`Splunk-AO-API-Key` in the current spec, `Galileo-API-Key` in older docs), a JWT from `/login/api_key` that expires after 24 hours, or HTTP Basic with a username and password, which the docs list as an option. We found no key scopes, expiry or rotation docs (18). Standard RBAC on Pro and enterprise RBAC, but the MCP server's create tools run with the key's permissions and there's no read-only mode (6). Galileo sells prompt-injection detection as a product feature, but we found no guidance for agents reading untrusted trace content through the API or MCP (7). No audit log found (0). No security.txt, no trust page (trust.galileo.ai doesn't resolve, galileo.ai/security is a 404), no SECURITY.md in either SDK repository and no SOC 2, ISO or HIPAA claim on the homepage, pricing page or privacy policy (2).); Overmind 70 (API keys are account-scoped or pinned to one project, carry read, write or both, expire after 30 to 365 days or never, are shown once and show last use, and rotation is documented as replace then revoke. MCP also takes OAuth 2.1 from api.overmindlab.ai with PKCE S256, dynamic registration, a revocation endpoint, one-hour access tokens and rotating refresh tokens, with scopes `overmind:read` and `overmind:write`, the default being read. A key can only mint keys with the scope and permissions it holds, since 29 October 2026 (30). Read keys see only read tools over MCP, and the REST API refuses writes from a read-only key since the same commit (#263). Only two tools are destructive and lifecycle tools are allowlisted by name in the catalogue. The docs tell agents to confirm the GPU and rate with the user before starting a dedicated deployment, but there's no server-side approval step (15). The MCP prompts tell the agent to treat code, comments and data as untrusted content, and script output is labelled untrusted in resources. We found no guidance for agents reading trace inputs and outputs back (8). The Console's notification list shows what agents and the CLI did in a project, and `overmind://activity` returns it over MCP. No exportable audit log was found (10). SECURITY.md lists GitHub private vulnerability reporting and an email with acknowledgement within 3 business days. No security.txt on either host and no bug bounty. The terms claim an ISO 27001 certified management system and the site links a Vanta Trust Center, whose robots.txt disallows crawling, so neither was checked (7). 30+15+8+10+7 = 70.)
- Payments & pricing, Overmind +10: Galileo API + MCP 20 (No x402 or other machine payment (0). Plan prices are public, Pro at $100 a month billed yearly for 50,000 traces, but overage only "scales based on number of traces" (10). The Free plan exists with 5,000 traces a month. The pricing page doesn't say whether a card is needed, so half (10). A person signs up in a browser at app.galileo.ai/sign-up (0).); Overmind 30 (No x402 or other machine payment. Paid work spends prepaid credits, and `402` is documented only for insufficient credits (0). Plan prices, the credit rate ($0.01) and per-model "from" prices for training and serving are published without login (20). A Free plan with $50 of credits once exists, but neither the pricing page nor the docs say whether a card is needed, so half (10). A person signs up in a browser at console.overmindlab.ai. MCP OAuth with dynamic registration still needs a sign-in, and `create_api_key` needs an existing connection (0). Self-hosting under AGPL is free but runs on the operator's own Modal, OpenRouter, AWS and Hugging Face accounts, so it isn't scored as the hosted option. 0+20+10+0 = 30.)
- Transparency & trust, Overmind +10: Galileo API + MCP 55 (Closed platform with terms from Galileo Technologies, Inc. Both SDKs are Apache-2.0 (15). The privacy policy was last updated on 1 November 2024, says data goes to servers in the US, allows de-identified customer data to be used for research and development and gives no retention periods. We found no DPA or subprocessor list (8). The rename to Splunk Agent Observability is dated 7 August 2026 in the release notes, but there's no timeline for api.galileo.ai, docs.galileo.ai or the SDKs (8). US data location stated, no subprocessors listed (5).); Overmind 65 (Platform under AGPL-3.0 and SDK and CLI under MIT, both OSI licences, with a paid commercial licence as an option and a licensing page that says which code is which (30). The privacy policy of 3 October 2026 gives retention (subscription plus 30 days, deletion within 90 days, logs 365 days, backups 7 days), AWS eu-west-1 hosting and OAuth token lifetimes. The terms of 1 March 2026 still describe an earlier security product, say data stays in UK and EU data centres while the privacy policy names model, training and inference providers without locations, and incorporate a DPA that isn't published. The two documents agree on retention but not on the product (15). The terms promise 90 days' written notice before withdrawing a capability and 30 days' notice of material changes. No dated deprecation notices were found (8). SDK analytics are an opt-in extra with three documented off switches. The hosted MCP server reports to PostHog with payloads dropped, which the docs don't mention, and no named sub-processor list was found beyond AWS, though the docs name Modal, OpenRouter, Clerk and Stripe (12). 30+15+8+12 = 65.)
- Reliability, Overmind +5: Galileo API + MCP 18 (No status page found. status.galileo.ai doesn't resolve and neither the homepage, the docs nor the Splunk docs link one (0). With no history to read, 5. No rate limits published for Galileo's own API. The pricing page lists custom rate limits on Enterprise only (0). The error catalogue marks each error retriable or not and the Python SDK raises a named `RateLimitError` on 429, but the 429 entries cover AI-provider limits, the OpenAPI spec declares no 429 and we found no `Retry-After` guidance (5). No SLA on any plan (0). The REST API is GA. The MCP server is labelled under construction until it reaches general availability (8).); Overmind 23 (No status page. status.overmindlab.ai doesn't resolve, /status returns 404 and neither the site nor the docs link one (0). With no history to read, 5. No request rate limits for the REST API, MCP or OTLP ingest were found in the docs. The only pacing settings, `JEV_REQUESTS_PER_MINUTE` and `JEV_TOKENS_PER_SECOND`, are self-hosting configuration for the scoring model (0). No 429 or Retry-After guidance, but the docs give safe-retry rules in detail. Launches, uploads, pipeline runs and inference take a stable `request_key`, identical retries return the existing receipt, changed payloads conflict, and `run_evaluation` is named as not idempotent (8). The terms promise commercially reasonable efforts toward 99.5 per cent availability a month, with remedies only in an order form or separate SLA, so half (5). The site doesn't call the service beta, but the SDK is classed "3 - Alpha" on its package metadata and the public repository is seven weeks old (5). 0+5+0+8+5+5 = 23.)
