Search the knowledge base for code examples only.
AI agents call grounded_search_code to retrieve information from Grounded Code MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from a personal knowledge base without creating, modifying, deleting, or executing anything. It is a passive search operation with no side effects, fitting the Read category. Severity is low because the blast radius of misuse is limited to information disclosure of already-trusted sources within the user's own knowledge base.
From the tool's definition Tool description states 'Search the knowledge base for code examples only.' The verb 'search' and the read-only nature of querying a knowledge base without modification indicate a retrieval operation.
Attacks that exploit this kind of access
Search the knowledge base for code examples only. It is categorised as a Read tool in the Grounded Code MCP MCP Server, which means it retrieves data without modifying state.
Register the Grounded Code MCP server in PolicyLayer and add a rule for grounded_search_code: 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 Grounded Code MCP. Nothing to install.
grounded_search_code 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 grounded_search_code 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 grounded_search_code. 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.
grounded_search_code is provided by the Grounded Code MCP server (michaelalber/grounded-code-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
