Find files matching a glob pattern.
AI agents call glob_files 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.
Glob pattern matching for file discovery is a read-only operation that retrieves information about the filesystem without modifying, deleting, or executing anything. It poses minimal risk as it only lists files matching a pattern, similar to shell commands like 'find' or 'ls' used for searching.
From the tool's definition Tool name is 'glob_files' and description states 'Find files matching a glob pattern.' This is a search/query operation with no side effects.
Attacks that exploit this kind of access
Find files matching a glob pattern. 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 glob_files: 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.
glob_files 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 glob_files 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 glob_files. 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.
glob_files 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.
glob_files is one line of TermPipe's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
