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 Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-reddit-archive). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 0 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability60
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 828 tokens (~276/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 Management23
- Stability observed for 7 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 4 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

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 →
reddit_history_comments ~297
Historical Reddit COMMENTS via the Arctic Shift archive — scope to a subreddit, a specific post (link_id), or both; requires at least one. Optionally filter by keyword (query, matched against comment body) and date range (after/before, ISO dates). Returns id, author, created_utc (ISO), score, body, link_id, permalink. No per-author aggregation is provided by this pack — results are the raw comments Arctic Shift's filters match, nothing rolled up into a user profile.
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | Optional ISO date (e.g. "2019-01-01") — only comments created on/after this date. |
| before | string | – | Optional ISO date (e.g. "2020-01-01") — only comments created before this date. |
| limit | number | – | Max comments to return (default 25, max 100). |
| link_id | string | – | Reddit post ID to fetch comments under, e.g. "ei9204" (with or without the "t3_" prefix). Provide this and/or subreddit. |
| query | string | – | Optional keyword — matched against comment body text. |
| sort | string | – | "asc" or "desc" by comment date (default "desc", newest first). |
| subreddit | string | – | Subreddit name without the r/ prefix, e.g. "datasets". Provide this and/or link_id. |
No output schema declared.
No examples provided.
reddit_history_posts ~308
Historical Reddit POSTS from one subreddit, back to ~2005 — via the Arctic Shift archive, not the live Reddit API (which the `reddit` pack uses and which only reaches ~1,000 recent results with no reliable date filter). PREFER for "Reddit posts about X in/before <year>", "what did r/<sub> post about Y historically", or any request the live reddit pack cannot date-filter. Filter by date range (after/before, ISO dates like "2019-01-01") and/or keyword (query, matched against title+body). Returns id, title, author, created_utc (ISO), score, num_comments, permalink. A subreddit Arctic Shift has never indexed is reported as a loud error, never a silent empty list.
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | Optional ISO date (e.g. "2019-01-01") — only posts created on/after this date. |
| before | string | – | Optional ISO date (e.g. "2020-01-01") — only posts created before this date. |
| limit | number | – | Max posts to return (default 25, max 100). |
| query | string | – | Optional keyword — matched against post title and body text. |
| sort | string | – | "asc" or "desc" by post date (default "desc", newest first). |
| subreddit | string | yes | Subreddit name without the r/ prefix, e.g. "datasets". |
No output schema declared.
No examples provided.
subreddit_activity ~168
Reddit subreddit identity and activity over time, via the Arctic Shift archive: subscriber count, subreddit creation date, all-time post/comment totals, earliest indexed post/comment, and monthly post/comment counts within a date window (default: the last 12 months). A subreddit Arctic Shift has never indexed is reported as a loud not-found error, never a silent empty result.
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | Optional ISO date (e.g. "2024-01-01") for the monthly-activity window; default is 12 months ago. |
| before | string | – | Optional ISO date (e.g. "2025-01-01") for the monthly-activity window; default is today. |
| subreddit | string | yes | Subreddit name without the r/ prefix, e.g. "datasets". |
No output schema declared.
No examples provided.
