Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability56
  • AI-judged instruction clarity (fair).Partial
  • Context-footprint check failed: tool/resource definitions use about 688 tokens (~137/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage77
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 19% of tool parameters carry a description.Partial
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

  • Implements a current MCP spec version (2026-07-28).Pass
Install

How do I install the ScoreIA Open Chamber MCP server?

ScoreIA Open Chamber is a hosted endpoint at https://scoreia.ai/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 5 exposed · ~616 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

enter_open_challenge ~357

Enter the public ScoreIA Open Chamber. The door has no account, API key, invitation or product allowlist. Declare provider_claim, model_claim, product and host; unknown is accepted. product is the model or slot under test (gpt-5.6-sol, composer-3, grok-4.6, unknown). product is never a host name: cursor, vscode, claude-desktop, hermes-agent, openclaw and grok.com are hosts. Example: product=gpt-5.6-sol host=cursor. list_suites is not enter; chambre-chrono-v0 is the public door. Preflight is optional metadata, never an admission gate. Every sealed attempt, including failure, creates a dated public card. Do not submit personal data or secrets.
