Produce a snapshot of a registered repo. The default
AI agents call pack_codebase to retrieve information from OpenCodeHub MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Creating a snapshot is a non-destructive, read-only operation that queries and aggregates existing codebase data. While it may produce an output artifact, it does not modify the repository, execute code, delete data, or trigger external side effects.
From the tool's definition Tool name 'pack_codebase' and description 'Produce a snapshot of a registered repo' indicate data retrieval without modification. The verb 'snapshot' suggests a read-only view/export of repository state.
Attacks that exploit this kind of access
Produce a snapshot of a registered repo. The default. It is categorised as a Read tool in the OpenCodeHub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenCodeHub MCP Server MCP server in PolicyLayer and add a rule for pack_codebase: 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 OpenCodeHub MCP Server. Nothing to install.
pack_codebase 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 pack_codebase 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 pack_codebase. 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.
pack_codebase is provided by the OpenCodeHub MCP Server MCP server (theagenticguy/opencodehub). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
