# start_stream Start a realtime analytics stream Agent View of the PolicyLayer registry record for `start_stream`. HTML page: https://policylayer.com/tools/coder-rl-claude-mcpserver-dev1/start-stream ## Facts - Tool: `start_stream` - Server: Claude MCP Server Ecosystem (`coder-rl/claude_mcpserver_dev1`) — https://policylayer.com/tools/coder-rl-claude-mcpserver-dev1.md - Homepage: https://github.com/Coder-RL/Claude_MCPServer_Dev1 - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "start_stream", "arguments": {} } } ``` ## Why start_stream is rated High This tool executes an operation that initiates a realtime data stream, which has side effects beyond simple data retrieval. While not destructive or financial, it activates an external service/process whose behavior and consequences depend on implementation details and arguments. The streaming operation could consume resources, trigger downstream processes, or have unintended effects if misconfigured by an agent. From the tool's own definition: "Tool name 'start_stream' combined with description 'Start a realtime analytics stream' indicates initiation of an external operation (streaming service)." ## Use case AI agents invoke start_stream to trigger actions in Claude MCP Server Ecosystem. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
