AI agents call wiki_summary to retrieve information from Basic MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data from Wikipedia without side effects. It neither modifies state, executes arbitrary operations, nor commits financial or destructive actions. Misuse (e.g., excessive requests) poses minimal risk compared to write, execute, or destructive tools.
From the tool's definition Tool description states 'Get a summary of a Wikipedia article' — a pure retrieval operation with no modification, deletion, or execution of code.
Attacks that exploit this kind of access
Get a summary of a Wikipedia article. It is categorised as a Read tool in the Basic MCP MCP Server, which means it retrieves data without modifying state.
Register the Basic MCP server in PolicyLayer and add a rule for wiki_summary: 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 Basic MCP. Nothing to install.
wiki_summary 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 wiki_summary 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 wiki_summary. 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.
wiki_summary is provided by the Basic MCP server (nimishgautam/basic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
