## 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**: 50/100
  - Malware scan not yet available for this package.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised build step with no custom scripting around it.
  - 0 of 28 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to SirjanSingh/oahelper-mcp).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 17 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 651 tokens (~81/item across 8 items; 8 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 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.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (8)

### `oahelper_search` (~69 tokens)

Find a company's OA question sets on OAHelper by name (e.g. "Amazon", "Kickdrum").

Lists each set with its company_ref, date and question counts. To download a
company's sets into the offline library, use oahelper_sync.

Input parameters:

- `company` (string, required)

Output parameters:

- `result` (string)

### `oahelper_sync` (~137 tokens)

Download one company's OAHelper content into the offline library, newest sets first:
set lists, every question statement, MCQ answers, and interview experiences.

Makes at most max_items live requests per call, then says how much is left, so call it
again to continue. Already-saved items cost nothing. Official solutions are NOT fetched
here because each one uses the account's daily solution quota; use oahelper_solution.
Read the result from library/<company>/index.md.

Input parameters:

- `company` (string, required)
- `include_images` (boolean)
- `include_interviews` (boolean)
- `max_items` (integer)

Output parameters:

- `result` (string)

### `oahelper_company` (~93 tokens)

List one OAHelper set page by slug or URL, e.g. "kickdrum-mcq24sep" or
https://www.oahelper.in/company-questions/kickdrum-mcq24sep. Returns question refs
for oahelper_question. For a company by name, use oahelper_search or oahelper_sync.

Input parameters:

- `refresh` (boolean)
- `slug_or_url` (string, required)

Output parameters:

- `result` (string)

### `oahelper_question` (~111 tokens)

Read one OAHelper question: full statement, MCQ answers with explanations (for MCQ
sets), any saved official solution, and optionally community solutions and images.
Saves it to the offline library.

ref_or_url: a question ref like "MjM3OHww" or a https://www.oahelper.in/problems/... URL.

Input parameters:

- `include_community` (boolean)
- `include_images` (boolean)
- `ref_or_url` (string, required)
- `refresh` (boolean)

Output parameters:

- `result` (string)

### `oahelper_solution` (~77 tokens)

Fetch OAHelper's official solution for one coding question (language: cpp, python,
java). Each new fetch uses one of the account's limited daily solution requests, so
only call this when the user asks for the official solution. Saved solutions are free.

Input parameters:

- `language` (string)
- `ref_or_url` (string, required)

Output parameters:

- `result` (string)

### `oahelper_interviews` (~70 tokens)

Interview experiences for a company from OAHelper (12 per page, most relevant first).
Saves each full write-up to library/<company>/interviews/ and returns a short list;
read the saved files for the full text.

Input parameters:

- `company` (string, required)
- `pages` (integer)

Output parameters:

- `result` (string)

### `oahelper_offline` (~52 tokens)

What is saved offline. No network call. With no company, lists every company in the
library; with a company, returns its index (sets, interviews, counts).

Input parameters:

- `company` (string)

Output parameters:

- `result` (string)

### `oahelper_status` (~42 tokens)

Session and usage status. online=true also checks Pro status with the site
(one request); by default no network call is made.

Input parameters:

- `online` (boolean)

Output parameters:

- `result` (string)

## Common questions

### What is the OAHelper MCP server?

OAHelper is an MCP server listed in the public MCP registry as io.github.SirjanSingh/oahelper-mcp. Your OAHelper Pro account: OA sets, MCQ answers, solutions and interview experiences, offline. This page covers its PyPI package (oahelper-mcp).

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

OAHelper scores 63 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. 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 OAHelper MCP server expose?

OAHelper exposes 8 tools: oahelper_search, oahelper_sync, oahelper_company, oahelper_question, oahelper_solution, and 3 more. Their descriptions and schemas cost roughly 651 tokens of context every time the server is loaded.

### Is the OAHelper MCP server still maintained?

OAHelper 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 OAHelper MCP server under?

OAHelper 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 OAHelper MCP server?

VerifyMCP ran 14 checks on OAHelper, covering Known CVEs, Install scripts, Dependency health, Source repository and 10 more. 2 items could not be completed, a gap on our side rather than a finding about OAHelper: Malware scan and Stability. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
