Why this score — causal attribution
Each penalty: measure → mechanism → effect → Δscore.
Schemas / desc · HIGH−5.4
0% typed+described params → schema = the contract the agent fills in → more malformed calls
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−1.2
capability 'prompts' declared but prompts/list empty → inconsistent capabilities → clients misled
Compliance · LOW−0.6
no OAuth discovery (.well-known missing) → RFC 9728/8414 not exposed → auth not auto-discoverable by clients

About parlel — FAQ
Is the parlel MCP server safe to use?+
CheckMCP audited parlel and gave it an MCP Score of 80/100 (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 parlel?+
parlel scores 80/100 (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 parlel expose, and what is its context cost?+
parlel exposes 8 tools, and its tools/list response costs roughly 1.6k tokens — paid on every request your agent makes to it. Lower is better for your context budget.
How was parlel scored?+
By probing the live MCP endpoint (https://api.parlel.com/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.
