Get detailed metadata for a specific ingested source document:
AI agents call grounded_source_info 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 performs a read-only query operation on stored source document metadata. It retrieves information without side effects, making it a Read category risk. The severity is low because metadata retrieval poses minimal risk—it cannot modify data, execute code, or cause damage even if invoked arbitrarily by an AI agent.
From the tool's definition Tool retrieves detailed metadata for a specific ingested source document. The name includes 'get' and 'info', and the description states it retrieves metadata with no indication of modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Get detailed metadata for a specific ingested source document:. 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_source_info: 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_source_info 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_source_info 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_source_info. 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_source_info 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.
