Find alternative packages to replace a given dependency.
AI agents call tool_find_alternatives to retrieve information from Codelens-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches for and recommends alternative packages, which is fundamentally a read operation that retrieves and presents information. No data is created, modified, deleted, or executed. The operation is informational only and suitable for research and comparison tasks, consistent with the server's stated purpose of researching libraries and comparing packages.
From the tool's definition Tool description states it 'Find[s] alternative packages' — a query/lookup operation that retrieves information about substitute dependencies without modifying any data or triggering external side effects.
Attacks that exploit this kind of access
Find alternative packages to replace a given dependency. It is categorised as a Read tool in the Codelens-MCP MCP Server, which means it retrieves data without modifying state.
Register the Codelens- MCP server in PolicyLayer and add a rule for tool_find_alternatives: 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 Codelens-MCP. Nothing to install.
tool_find_alternatives 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 tool_find_alternatives 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 tool_find_alternatives. 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.
tool_find_alternatives is provided by the Codelens- MCP server (yashkashte5/codelens-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
