What cross_repo_traverse does on CogniRepo
AI agents call cross_repo_traverse to retrieve information from CogniRepo without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why cross_repo_traverse is rated Low
The tool appears designed to traverse repository structures to retrieve or query information across repositories. While the description is empty, the naming convention ('traverse'), the server's stated purpose of providing persistent memory and context, and the presence of sibling read-focused tools (search, graph, context retrieval) all indicate this is a Read operation with no side effects.
From the tool's definition Tool name 'cross_repo_traverse' suggests navigation/traversal of repository data. Sibling tools like 'cross_repo_search', 'dependency_graph', and 'context_pack' indicate this server provides query and retrieval functions.
Attacks that exploit this kind of access
The rule that runs cross_repo_traverse safely
PolicyLayer is an MCP gateway: it sits between your AI agents and CogniRepo, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cross_repo_traverse, this is the rule to start with:
cross_repo_traverse is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect CogniRepo, apply this rule, and every cross_repo_traverse call is checked against it from then on.
Questions about cross_repo_traverse
cross_repo_traverse is a read tool on the CogniRepo MCP server. It is categorised as a Read tool in the CogniRepo MCP Server, which means it retrieves data without modifying state.
Register the CogniRepo MCP server in PolicyLayer and add a rule for cross_repo_traverse: 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 CogniRepo. Nothing to install.
cross_repo_traverse 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 cross_repo_traverse 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 cross_repo_traverse. 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.
cross_repo_traverse is provided by the CogniRepo MCP server (pypi:cognirepo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
