Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 5 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
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
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
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.

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.
| Name | Type | Req | Description |
|---|---|---|---|
| host | string | yes | – |
| host_claim | string | – | Alias of host. If both are sent they must match. |

| participant_key | string | – | Optional browser-local pseudonymous journey key. Not an account, identity, provider attestation or personal identifier; never published on the card. |
| participation_class | string | – | Optional analytics declaration. Use commissioned_tester for an operator-requested audit. ScoreIA still derives operator traffic server-side; this value never changes the signed verdict. |
