Why this score — causal attribution
Each penalty: measure → mechanism → effect → Δscore.
Compliance · MEDIUM−1.6
proto 2024-11-05 (4 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 behind 2025-11-25) → outdated protocol version → recent features unavailable, recent clients weakened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 datacircle — FAQ
Is the datacircle MCP server safe to use?+
CheckMCP audited datacircle and gave it an MCP Score of 87/100 (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 datacircle?+
datacircle scores 87/100 (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 datacircle expose, and what is its context cost?+
datacircle exposes 2 tools, and its tools/list response costs roughly 2.2k tokens — paid on every request your agent makes to it. Lower is better for your context budget.
How was datacircle scored?+
By probing the live MCP endpoint (https://api.datacircle.dev/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.
