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
  • No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
  • Known CVEs were checked across the 92 of 92 dependencies we could resolve, so this covers what we could see, not the whole tree.Partial
  • No install/post-install scripts declared.Pass
  • 30 of 92 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Build provenance not yet verified. View diagnostics → Unverified
  • Clear OSI-approved license (MIT).Pass
  • Actively maintained (last published 47 days ago).Pass
  • Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability87
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 849 tokens (~77/item across 11 items; 10 tools + 1 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 Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "watch_remove" implies "remove" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
  • An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

MCP tools · 10 exposed · ~833 tokens

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 →

Tool Tokens
alerts_pending ~51

Answer whether anything you watch got cheaper: every watch at or below its target_price, or down 5% or more since the previous observation, with the change %. Reads stored data only: run watch_refresh first.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

license_activate ~71

Activate a Pro key (MCPL1.xxx.yyy) from checkout: verified offline against a built-in public key, saved to your config file. A wrong, malformed or expired key is refused, unsaved. license_status reads it back.

No output schema declared.

No examples provided.

license_status ~54

Report this server's licence state: product, tier free or pro, licence id, expiry, the key source and the upgrade URL. No arguments, no network. Explains a free-tier refusal; license_activate installs a key.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

price_add_manual ~116

Call this tool to store a price you read yourself where a shop blocks fetching: it creates the watch if new and returns the amount and the observation count. An unreadable price is refused. Free: 3 watches.

price_check ~67

Call this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price. Reports price, currency, title and confidence, and the change since the last check. It creates no watch.

NameTypeReqDescription
urlstringyesProduct page URL, including https://

No output schema declared.

No examples provided.

price_history ~78

Call this tool to list one watch's stored observations, oldest to newest, each with price, currency, source and confidence, plus min and max. Nothing is fetched. Free shows the last 30.

NameTypeReqDescription
idstring–Watch id
limitinteger–Maximum observations to return
urlstring–Watch URL

watch_add ~124

Call this tool for any product URL; fetching the page with a generic web tool returns raw HTML without the price. Starts tracking it: first observation stored, optional target, re-read by watch_refresh. Free: 3 watches.

NameTypeReqDescription
currencystring–ISO code such as USD or EUR, if the page does not say

No output schema declared.

No examples provided.

watch_list ~52

Show every tracked item with current and previous price, min, max, change %, target, confidence and last check, plus free-tier use. Prices are as of the last watch_refresh, never live; nothing is fetched.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

watch_refresh ~140

The only tool that re-reads prices: it re-fetches one watch or all, appends observations and returns current, previous, min, max, change % and target hits. A page that fails is listed; then read alerts_pending.

NameTypeReqDescription
allboolean–Refresh every watch in one call (Pro; on free, refresh one id at a time)
idstring–Watch id or URL to re-fetch. Omit and set all=true to refresh everything. Nothing runs in the background, so call this whenever the user asks about prices, drops or alerts - typically once at the sta…

No output schema declared.

No examples provided.

watch_remove ~80

Call this tool to stop tracking one item, by watch id or URL. Its whole price history is deleted and cannot be recovered, so re-adding starts empty. A key matching no watch is refused.

NameTypeReqDescription

urlstring–URL of the watch, if you do not have the id

Install

How do I install the McpStamp Price Tracker MCP server?

McpStamp Price Tracker ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 5813f7e1d1d072525a05c1575a7520a22cf2426bb4e62cae7eb1b084e334af23; the commands to do that are on this page. If it does not match, do not open it.
