Receive shared context and pointers from other Claude instances
AI agents call receive_context to retrieve information from Claude Senator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves context and data shared by other Claude instances without modifying, deleting, or executing external operations. It fits the Read category (retrieves data; no side effects).
From the tool's definition Tool name is 'receive_context' and description states it 'Receive[s] shared context and pointers from other Claude instances' — a retrieval operation with no modification or deletion of data.
Attacks that exploit this kind of access
Receive shared context and pointers from other Claude instances. It is categorised as a Read tool in the Claude Senator MCP Server, which means it retrieves data without modifying state.
Register the Claude Senator MCP server in PolicyLayer and add a rule for receive_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 Claude Senator. Nothing to install.
receive_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 receive_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 receive_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.
receive_context is provided by the Claude Senator MCP server (vvkmnn/claude-senator-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
