Get active context
AI agents call get_active_context to retrieve information from SDOF Knowledge Base without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries the current active context from the knowledge base without creating, modifying, deleting, or executing operations. It is a simple data retrieval operation with no capability to affect system state. The low severity reflects minimal blast radius—worst case, an AI agent gains knowledge of the current context, which is informational only.
From the tool's definition Tool name 'get_active_context' and description 'Get active context' indicate a retrieval operation. The verb 'get' is a classic read-only action that retrieves data without modification or side effects.
Attacks that exploit this kind of access
Get active context. It is categorised as a Read tool in the SDOF Knowledge Base MCP Server, which means it retrieves data without modifying state.
Register the SDOF Knowledge Base MCP server in PolicyLayer and add a rule for get_active_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 SDOF Knowledge Base. Nothing to install.
get_active_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 get_active_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 get_active_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.
get_active_context is provided by the SDOF Knowledge Base MCP server (tgf-between-your-legs/sdof-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
