Navigate the project graph. Actions: expand|deps|usages|call_chain|sub_projects. deps returns code calls plus web template/style/component links when present.
AI agents call navigate to retrieve information from Project Graph without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
All listed actions (expand, deps, usages, call_chain, sub_projects) are read/query operations that retrieve structural information about the project graph such as dependencies, usages, and call chains. No data is created, modified, or deleted.

Attacks that exploit this kind of access
Navigate the project graph. Actions: expand|deps|usages|call_chain|sub_projects. deps returns code calls plus web template/style/component links when present. It is categorised as a Read tool in the Project Graph MCP Server, which means it retrieves data without modifying state.
Register the Project Graph MCP server in PolicyLayer and add a rule for navigate: 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 Project Graph. Nothing to install.
navigate 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 navigate 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 navigate. 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.
navigate is provided by the Project Graph MCP server (rnd-pro/project-graph-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
