getCrateInfo
AI agents call getCrateInfo to retrieve information from Mcp Docsrs without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves crate information from Docs.rs documentation—a read-only query with no side effects. No data is modified, deleted, or external operations triggered. Classification as Read with low severity is appropriate for documentation access.
From the tool's definition Tool name 'getCrateInfo' and server context (Docs.rs MCP server for accessing Rust crate documentation) indicate retrieval of crate metadata. Sibling tools like 'searchCrates', 'getItemDefinition', and 'listFeatures' are all Read operations.
Attacks that exploit this kind of access
getCrateInfo. It is categorised as a Read tool in the Mcp Docsrs MCP Server, which means it retrieves data without modifying state.
Register the Mcp Docsrs MCP server in PolicyLayer and add a rule for getCrateInfo: 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 Mcp Docsrs. Nothing to install.
getCrateInfo 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 getCrateInfo 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 getCrateInfo. 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.
getCrateInfo is provided by the Mcp Docsrs MCP server (shuakami/mcp-docsrs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
