Typosquatting detection optimised for the top 500 frontend packages (React, Vite, Axios, Lodash, etc.). Fewer false positives than a full npm scan.

What frontend_security_detect_typosquatting does on DataNexus MCP
AI agents call frontend_security_detect_typosquatting to retrieve information from DataNexus MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
ecosystem | string | — | Package ecosystem: npm or pypi. Default npm. |
package_name | string | — | Package name e.g. requests. Required. |
Parameters from the server's own tool schema.
Why frontend_security_detect_typosquatting is rated Low
This tool retrieves and analyzes security metadata about npm/pypi packages to detect potential typosquatting attacks, but performs no mutations, executions, deletions, or financial operations. It is a pure query/detection mechanism with no side effects, matching the 'Read' category definition of retrieving or querying data without side effects.
From the tool's definition Tool description explicitly states 'Read-only. No side effects. Idempotent.' and 'Typosquatting detection optimised for the top 500 frontend packages' with parameters like package_name and ecosystem used for detection/analysis only.
Attacks that exploit this kind of access
The rule that runs frontend_security_detect_typosquatting safely
PolicyLayer is an MCP gateway: it sits between your AI agents and DataNexus MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For frontend_security_detect_typosquatting, this is the rule to start with:
frontend_security_detect_typosquatting is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect DataNexus MCP, apply this rule, and every frontend_security_detect_typosquatting call is checked against it from then on.
Questions about frontend_security_detect_typosquatting
Typosquatting detection optimised for the top 500 frontend packages (React, Vite, Axios, Lodash, etc.). Fewer false positives than a full npm scan. For backend packages, use security_detect_typosquatting instead. package_name: Package name to check. Required. ecosystem: npm or pypi — default npm. Uses Damerau-Levenshtein distance ≤ 2 against a curated frontend-package corpus. Returns is_likely_typosquat, closest_match, distance, and risk_level (LOW/MEDIUM/HIGH). Read-only. No side effects. Idempotent. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="frontend_security_detect_typosquatting", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}". It is categorised as a Read tool in the DataNexus MCP MCP Server, which means it retrieves data without modifying state.
frontend_security_detect_typosquatting accepts 2 parameters: ecosystem, package_name. The full parameter table on this page comes from the server's own tool schema.
Register the DataNexus MCP server in PolicyLayer and add a rule for frontend_security_detect_typosquatting: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches DataNexus MCP. Nothing to install.
frontend_security_detect_typosquatting is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the frontend_security_detect_typosquatting rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for frontend_security_detect_typosquatting. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
frontend_security_detect_typosquatting is provided by the DataNexus MCP server (dev-7bd0/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
