Why this score — causal attribution
Each penalty: measure → mechanism → effect → Δscore.
Compliance · MEDIUM−3.6
0 declared annotations → destructiveHint/openWorldHint missing -> worst-case defaults → the tool is treated as destructive & open-world by clients
Compliance · MEDIUM−1.1
proto 2025-03-26 (3 rev. behind 2025-11-25) → outdated protocol version → recent features unavailable, recent clients weakened
Compliance · LOW−0.6
no OAuth discovery (.well-known missing) → RFC 9728/8414 not exposed → auth not auto-discoverable by clients

About surface — FAQ
Is the surface MCP server safe to use?+
CheckMCP audited surface and gave it an MCP Score of 86/100 (grade B) — good — only minor issues. The audit runs an OWASP MCP Top 10 security pass (tool poisoning, hardcoded secrets, command injection, the lethal trifecta) against the live endpoint; see the per-pillar breakdown and the "why this score" attribution on this page, and re-audit anytime at checkmcp.dev.
What is the MCP Score of surface?+
surface scores 86/100 (grade B) on CheckMCP's vendor-neutral audit across six weighted pillars — security, tool design, schemas, context-cost, compliance and coverage — with reliability measured and shown but not yet credited.
How many tools does surface expose, and what is its context cost?+
surface exposes 1 tool, and its tools/list response costs roughly 99 tokens — paid on every request your agent makes to it. Lower is better for your context budget.
How was surface scored?+
By probing the live MCP endpoint (https://nova-otter-delta-cloud.grok.me/mcp), inspecting its tools, schemas and protocol compliance, running an OWASP MCP Top 10 security pass, and measuring the token cost of tools/list — then attributing every penalty as measure → mechanism → effect. The methodology is open: checkmcp.dev/#methodology.
