AI agents call segment_get_source to retrieve information from UnClick without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
This tool retrieves configuration and status information about a Segment data source. It performs a read-only query operation with no capability to modify, delete, or execute external actions. The 'enabled state' detail is descriptive metadata, not a state change. Misuse carries minimal risk as it only exposes existing source configuration data.
From the tool's definition Tool name is 'segment_get_source' and description states 'Get details for a single Segment source' - the verb 'Get' and phrase 'Get details' indicate retrieval of information without modification or side effects.

Register the UnClick MCP server in PolicyLayer and add a rule for segment_get_source: 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 UnClick. Nothing to install.
segment_get_source 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 segment_get_source 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 segment_get_source. 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.
segment_get_source is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
