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 Security0
- 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 could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
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 50 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability67
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 760 tokens (~253/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 Management27
- Stability observed for 8 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.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
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.
How do I install the MCP Retrieval server?
MCP Retrieval 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. The MCP registry declares no SHA-256 for this bundle, so there is no published digest to check the download against.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
web_scrape Web scrape ~233
Downloads pages by their links and returns the main text as markdown. Links are fetched in parallel; a single call handles up to 10 of them, so batch all links you need into one call instead of calling the tool per link. Size: the 'max_chars' limit applies to each page separately, not to the whole response — 5 links stay under the limit each and the response holds all 5 texts. The limit counts characters, not tokens. A page cut short ends with '[truncated]' and its 'truncated' field is set; the cut-off part cannot be fetched afterwards, so treat what you got as all there is for that page.
| Name | Type | Req | Description |
|---|---|---|---|
| max_chars | integer | – | truncate each page separately to N characters, default and maximum 20000; only lowers the limit, higher values are ignored |
| remove_links | boolean | – | strip markdown links from the text |
| robots_txt | boolean | – | respect the page robots.txt |
| timeout_ms | integer | – | timeout for the whole call in milliseconds |
| urls | null|array | yes | links to pages, downloaded in parallel |
| Name | Type | Req | Description |
|---|---|---|---|
| metadata | object | yes | – |
| results | null|array | yes | – |
No examples provided.
web_search Web search ~320
Searches the web for one or more queries and returns snippets with links. Queries run in parallel. IMPORTANT: Always write search queries in English for best results and relevance. For images use the 'web_search_images' tool; both tools can be called in the same turn when a query needs text and images. Freshness: set the 'date' field to restrict results by recency — 'd' (past day), 'w' (past week), 'm' (past month), 'y' (past year). Use it to prefer the most recent pages when the user asks about news or anything time-sensitive; leave it empty for all time. Query operators (put them inside the query string itself): 'site:example.com term' limits the search to one site; 'filetype:pdf term' restricts to a file type; double quotes "exact phrase" force an exact match; a leading '-' excludes a word (term -foo); 'intitle:term' requires the word in the page title. Operators can be combined, e.g. 'site:arxiv.org filetype:pdf transformers'.
| Name | Type | Req | Description |
|---|---|---|---|
| date | string | – | filter results by freshness: 'd' past day, 'w' past week, 'm' past month, 'y' past year; empty means all time |
| max_results | integer | – | maximum number of snippets per query |
| queries | null|array | yes | search queries in English, executed in parallel |
| timeout_ms | integer | – | timeout for the whole call in milliseconds |

| results | null|array | yes | – |
No examples provided.
web_search_images Web image search ~207
Searches for images by one or more queries, executed in parallel. IMPORTANT: Queries must be in English ONLY. Freshness: set the 'date' field to restrict results by recency — 'd' (past day), 'w' (past week), 'm' (past month), 'y' (past year); leave it empty for all time. Query operators can be embedded in the query string: 'site:example.com term' limits to one site, double quotes "exact phrase" force an exact match, and a leading '-' excludes a word.
| Name | Type | Req | Description |
|---|---|---|---|
| date | string | – | filter results by freshness: 'd' past day, 'w' past week, 'm' past month, 'y' past year; empty means all time |
| max_images | integer | – | maximum number of images per query |
| queries | null|array | yes | queries in English for image search |

Is the MCP Retrieval server safe to use?
MCP Retrieval scores 43 out of 100 on VerifyMCP. 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 MCP Retrieval server expose?
MCP Retrieval exposes 3 tools: web_scrape, web_search, web_search_images. Their descriptions and schemas cost roughly 760 tokens of context every time the server is loaded.
What licence is the MCP Retrieval server under?
MCP Retrieval declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
