Category Search and Retrieval
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
- Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 31 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to JerryLiu369/agent-web-search). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 12 days ago).Pass
- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
Schema Quality & AI Usability76
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 236 tokens (~236/item across 1 items; 1 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 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 Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 1 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (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 →
web_search ~236
Search the web using agent-native semantic search and LLM-grounding backends. Optimized for complete natural-language questions rather than traditional keyword queries. Enabled providers: DuckDuckGo web search; Exa web search; Parallel LLM-optimized web search. Use a complete natural-language question. Failed providers are omitted from successful responses. If every enabled provider fails, the call returns a tool error with code all_providers_failed and per-provider diagnostics.
| Name | Type | Req | Description |
|---|---|---|---|
| max_results | integer | – | Desired maximum number of results. Providers enforce this natively or as a best-effort prompt constraint. |
| providers | array | – | Optional subset of the providers enabled at startup. |
| query | string | yes | A complete, detailed natural-language question or intent. Do NOT use fragmented keyword queries (e.g. avoid 'NVDA earnings'); instead pass the full question (e.g. 'What were the key highlights and ma… |
