Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security23
- Malware scan not yet available for this package.Unverified
- Known CVEs were checked across the 96 of 96 dependencies we could resolve, so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- 31 of 96 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 56 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability80
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 460 tokens (~153/item across 3 items; 3 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 Management90
- Stability observed for 27 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

- 20 Sept 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 87 to 90. That category is still filling its 30-day observation window: 26 days of observed history at the previous scan, 27 at this one. The score rises as the window fills, whether or not the server changes.

No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

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 →
check_ai_slop Check text for AI-writing style tells ~170
Score any prose 0-100 on how human it reads (100 = reads human) by counting six families of style tells: LLM word/phrase density, em-dash density, formulaic structures, sentence-length uniformity, lack of specifics, and over-perfect bullet lists. Returns the score, a verdict, per-dimension sub-scores with the raw counts that produced them, and up to 6 concrete fixes. Fully deterministic and local: no LLM call, no network, same input always gives the same number. This measures STYLE, not authorship — it is a tells counter, not an AI detector.
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | The prose to score. At least ~200 characters gives a reliable read; shorter text still scores but the sentence-rhythm dimension is skipped. |
No output schema declared.
No examples provided.
get_slop_stats Benchmark stats from 239 real landing pages ~86
Return the reference distribution for grade_landing_copy: 239 real landing pages (min 41, median 79, mean 80.1, 19 perfect scores), how often each tell fires across them, the 10 lowest-scoring domains, and the score distribution. Use it to tell a user whether their score is actually good. Static local data, no network.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
grade_landing_copy Grade landing-page hero copy ~204
Score a landing-page hero (headline + sub-headline + call-to-action button) 0-100 across five weighted dimensions: Anti-hype (25), Specificity (25), Clarity (25), Headline shape (13), CTA (12). Returns the score, a verdict, per-dimension sub-scores with raw counts, short flags, and up to 6 targeted rewrites. Deterministic, no LLM, no network. This is the same engine used to score the public 239-page dataset exposed by get_slop_stats, so scores are directly comparable to real landing pages.
| Name | Type | Req | Description |
|---|---|---|---|
| cta | string | – | The call-to-action button label, e.g. "Start your first invoice". Optional, but an empty CTA scores 0 on that dimension. |
| headline | string | yes | The hero headline (h1). |
| subhead | string | – | The sub-headline / first sub-line under the h1. Optional. |
No output schema declared.
No examples provided.
What is the AI Slop Checker MCP server?
AI Slop Checker is an MCP server listed in the public MCP registry as io.github.parweb/ai-slop-checker. Deterministic offline scorer for AI-writing tells in text and landing copy. This page covers its MCPB bundle (https://github.com/parweb/mcp-ai-slop-checker/releases/download/v1.0.2/mcp-ai-slop-checker.mcpb).
Is the AI Slop Checker MCP server safe to use?
AI Slop Checker scores 61 out of 100 on VerifyMCP. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the AI Slop Checker MCP server expose?
AI Slop Checker exposes 3 tools: check_ai_slop, grade_landing_copy, get_slop_stats. Their descriptions and schemas cost roughly 460 tokens of context every time the server is loaded.
What licence is the AI Slop Checker MCP server under?
AI Slop Checker declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
