Download and return file content by ID. Truncates large files.
AI agents call get_file_content to retrieve information from AgentSpawnMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file content without modifying, deleting, or executing anything. It is a straightforward read operation that queries and returns data. Severity is low because file retrieval has limited blast radius unless the files contain highly sensitive data, but that is contextual and not inherent to the tool's operation.
From the tool's definition Tool description states 'Download and return file content by ID' — a retrieval operation with no modification or deletion. The truncation of large files is a read-side effect, not a write or destructive action.
Attacks that exploit this kind of access
Download and return file content by ID. Truncates large files. It is categorised as a Read tool in the AgentSpawnMCP MCP Server, which means it retrieves data without modifying state.
Register the AgentSpawn MCP server in PolicyLayer and add a rule for get_file_content: 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 AgentSpawnMCP. Nothing to install.
get_file_content 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 get_file_content 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 get_file_content. 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.
get_file_content is provided by the AgentSpawn MCP server (sandsaber/agentspawnmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
