AI agents call analyze_operators to retrieve information from Rxjs without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a code analysis/linting tool that examines RxJS patterns and provides insights. It retrieves and queries information about code structure and patterns but does not execute streams, modify data, delete anything, or trigger external operations.
From the tool's definition Tool name 'analyze_operators' and description 'Analyze RxJS code for creation functions, operators, performance patterns, and best practices' indicates static analysis and inspection of code without execution or modification of external state.
Attacks that exploit this kind of access
Analyze RxJS code for creation functions, operators, performance patterns, and best practices. It is categorised as a Read tool in the Rxjs MCP Server, which means it retrieves data without modifying state.
Register the Rxjs MCP server in PolicyLayer and add a rule for analyze_operators: 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 Rxjs. Nothing to install.
analyze_operators 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 analyze_operators 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 analyze_operators. 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.
analyze_operators is provided by the Rxjs MCP server (shuji-bonji/rxjs-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
