Read contents of a file. Supports partial reads.
AI agents call read_file to retrieve information from TermPipe MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves file contents without side effects. No data is created, modified, deleted, or executed. This is a straightforward read operation with minimal security risk, though confidence is not higher than 0.95 due to the broader TermPipe context (which provides 'direct terminal access') potentially allowing access to sensitive files.
From the tool's definition Tool name is 'read_file' and description states 'Read contents of a file. Supports partial reads.' This explicitly describes retrieval without modification or execution.
Attacks that exploit this kind of access
Read contents of a file. Supports partial reads. It is categorised as a Read tool in the TermPipe MCP MCP Server, which means it retrieves data without modifying state.
Register the TermPipe MCP server in PolicyLayer and add a rule for read_file: 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 TermPipe MCP. Nothing to install.
read_file 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 read_file 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 read_file. 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.
read_file is provided by the TermPipe MCP server (wbind-core/termpipe-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
