AI agents call retrieve_context to retrieve information from Wikimcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves information from existing wiki pages without creating, modifying, deleting, or executing any operations. It is a pure read operation that fetches and returns contextual information. The blast radius of misuse is minimal—an AI agent could only retrieve irrelevant or sensitive information already stored in the wiki, but cannot alter state or cause irreversible harm.
From the tool's definition Tool name 'retrieve_context' and description 'Return contextual snippets from the most relevant wiki pages' indicates data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Return contextual snippets from the most relevant wiki pages. It is categorised as a Read tool in the Wikimcp MCP Server, which means it retrieves data without modifying state.
Register the Wiki MCP server in PolicyLayer and add a rule for retrieve_context: 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 Wikimcp. Nothing to install.
retrieve_context 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 retrieve_context 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 retrieve_context. 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.
retrieve_context is provided by the Wiki MCP server (mohith-das/wikimcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
