AI agents call search to retrieve information from Delta-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves search results from documentation without creating, modifying, deleting, or executing any code. This is a standard read-only information retrieval operation with minimal security risk. The low severity reflects that misuse would only expose data the agent can already access.
From the tool's definition Tool is named 'search' with description 'Search docs and return top results' — indicates querying/retrieving information with no modification or execution of external operations.
Attacks that exploit this kind of access
Search docs and return top results. It is categorised as a Read tool in the Delta-MCP MCP Server, which means it retrieves data without modifying state.
Register the Delta- MCP server in PolicyLayer and add a rule for search: 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 Delta-MCP. Nothing to install.
search 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 search 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 search. 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.
search is provided by the Delta- MCP server (norhther/delta-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
