## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100

  - Actively maintained (last published 7 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 65/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 997 tokens (~199/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.

- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (5)

### `search_questions` (~138 tokens)

Search for questions on StackOverflow or any StackExchange site. Returns title, body, score, answer count, tags, and link.

Input parameters:

- `_apiKey` (string): Optional — a StackExchange API key (free, 10k/day) for a dedicated quota. The gateway supplies a platform key; pass your own only to override.
- `limit` (number): Number of results to return (1-20, default 5)
- `query` (string, required): Search query string
- `site` (string): StackExchange site slug (default: stackoverflow). Examples: serverfault, superuser, askubuntu, math, physics

### `get_answers` (~105 tokens)

Get answers for a specific StackExchange question by ID. Returns answer body, score, and whether it is accepted.

Input parameters:

- `_apiKey` (string): Optional — a StackExchange API key (free, 10k/day) for a dedicated quota. The gateway supplies a platform key; pass your own only to override.
- `question_id` (number, required): The numeric question ID from the question URL
- `site` (string): StackExchange site slug (default: stackoverflow)

### `stack_get_user` (~174 tokens)

Look up a StackExchange user by numeric ID. Returns display name, reputation, badges (gold/silver/bronze counts), location, website, account age, last access, and per-site activity counts (questions/answers). Works on any StackExchange site (default: stackoverflow).

Input parameters:

- `_apiKey` (string): Optional — a StackExchange API key (free, 10k/day) for a dedicated quota. The gateway supplies a platform key; pass your own only to override.
- `site` (string): StackExchange site slug (default: stackoverflow). Examples: serverfault, superuser, askubuntu, math, physics
- `user_id` (number, required): The numeric StackExchange user ID (visible in profile URL, e.g., stackoverflow.com/users/17034 → 17034)

### `list_questions_by_tag` (~269 tokens)

Browse questions by TAG, sorted by votes or recency — answers "top questions tagged <tag>", "trending <tag> questions this week/month", "most-voted <tag> questions". Returns title, score, answer count, whether answered, view count, tags, and link (call get_answers with a returned question_id to read answers). Combine tags with ";" for AND (e.g. "kubernetes;helm"). Distinct from search_questions, which is keyword-based.

Input parameters:

- `_apiKey` (string): Optional — a StackExchange API key (free, 10k/day) for a dedicated quota. The gateway supplies a platform key; pass your own only to override.

- `site` (string): StackExchange site slug (default: stackoverflow). Examples: serverfault, superuser, askubuntu, math, physics
- `sort` (string): Sort order: votes (default, all-time top), month or week (trending recently), activity (recently active), creation (newest), hot.
- `tag` (string, required): Tag to browse (e.g. "rust", "kubernetes"). Combine with ";" for AND ("react;typescript").

### `stack_tags` (~259 tokens)

List or search StackOverflow / StackExchange tags with question counts and synonym info — top tags by popularity, tags matching a name fragment, or stats for specific tags. Answers "most popular StackOverflow tags", "how many questions are tagged X", "which tags have more than N questions". Example: stack_tags({ sort: "popular", limit: 20 }) or stack_tags({ inname: "python" })

Input parameters:

- `_apiKey` (string): Optional — a StackExchange API key (free, 10k/day) for a dedicated quota. The gateway supplies a platform key; pass your own only to override.
- `inname` (string): Filter to tags whose name contains this fragment, e.g. "python"
- `limit` (number): Max tags to return, 1-100 (default 20)
- `min_count` (number): Only return tags with at least this many questions (server-side when sort=popular)
- `site` (string): StackExchange site (default stackoverflow)
- `sort` (string): popular (question count, default) | name | activity
- `tags` (string): Exact tag names to look up, semicolon-separated, e.g. "java;python;rust"

## Common questions

### What is the Stackexchange MCP server?

Stackexchange is an MCP server listed in the public MCP registry as io.github.pipeworx-io/stackexchange. StackExchange MCP, wraps the StackExchange API v2.3 (free, no auth required for read). This page covers its npm package (@pipeworx/mcp-stackexchange).

### Is the Stackexchange MCP server safe to use?

Stackexchange scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Stackexchange MCP server expose?

Stackexchange exposes 5 tools: search_questions, get_answers, stack_get_user, list_questions_by_tag, stack_tags. Their descriptions and schemas cost roughly 945 tokens of context every time the server is loaded.

### Is the Stackexchange MCP server still maintained?

Stackexchange is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Stackexchange MCP server under?

Stackexchange declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Stackexchange MCP server?

VerifyMCP ran 16 checks on Stackexchange, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
