Compare two saved register contexts.
AI agents call diff_context to retrieve information from MCPEmulate without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and compares two previously saved register contexts. It performs no modifications, executions, or deletions — it is purely an analytical/read operation with no side effects.

Attacks that exploit this kind of access
Compare two saved register contexts. It is categorised as a Read tool in the MCPEmulate MCP Server, which means it retrieves data without modifying state.
Register the MCPEmulate MCP server in PolicyLayer and add a rule for diff_context: 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 MCPEmulate. Nothing to install.
diff_context 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 diff_context 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 diff_context. 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.
diff_context is provided by the MCPEmulate MCP server (labguy94/mcpemulate). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
