About folklore — FAQ
Is the folklore MCP server safe to use?+
CheckMCP audited folklore and gave it an MCP Score of 83/100 (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 folklore?+
folklore scores 83/100 (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 folklore expose, and what is its context cost?+
folklore exposes 11 tools, and its tools/list response costs roughly 11k tokens — paid on every request your agent makes to it. Lower is better for your context budget.
How was folklore scored?+
By probing the live MCP endpoint (https://api.helena.bio/folklore/v1/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.
