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 Security57
- 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
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability77
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 376 tokens (~75/item across 5 items; 5 tools + 0 resources), lean.Pass
- 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 Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.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 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the io.github.meltingpixelsai/zero-core-verify MCP server?
io.github.meltingpixelsai/zero-core-verify is a hosted endpoint at https://verify.rugslayer.com/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 →
get_service_quality ~68
Get aggregated quality scores for a service based on all past verifications. Returns average completeness, accuracy, pass rate, format compliance rate, SLA compliance rate, and quality trend.
| Name | Type | Req | Description |

| service_id | string | yes | Service identifier to query (e.g. 'harvey-tools/scrape_url') |
No output schema declared.
No examples provided.
health ~20
Check Harvey Verify server status, uptime, and payment network configuration.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_tools ~25
List all available Harvey Verify tools with pricing and input requirements. Use this for discovery.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
report_outcome ~114
Record a simple pass/fail outcome report for a service call. No LLM analysis - just logs the result to the quality database. Cheaper alternative to verify_outcome when you only need to record success/failure.

verify_outcome ~149
Post-transaction verification using LLM-as-judge. Checks if a service delivered what was promised. Returns completeness score, accuracy score, format compliance, SLA adherence, issues list, and overall pass/fail.
| Name | Type | Req | Description |
|---|---|---|---|
| expected_schema | string | – | Expected output format or JSON schema |
| request_description | string | yes | What was requested from the service |
| response_data | string | yes | The actual response/output received from the service |
| service_id | string | – | Service identifier for quality tracking (e.g. 'harvey-tools/scrape_url') |
| sla_requirements | string | – | SLA requirements to check against (e.g. 'response under 5s, must include all fields') |
