AI agents call gossip_guide to retrieve information from Gossipcat without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though gossip_guide only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Call this when you want to READ the docs, not when you need LLM context. The LLM-facing auto-load lives in gossip_status().. It is categorised as a Read tool in the Gossipcat MCP Server, which means it retrieves data without modifying state.
Register the Gossipcat MCP server in PolicyLayer and add a rule for gossip_guide: 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 Gossipcat. Nothing to install.
gossip_guide 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 gossip_guide 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 gossip_guide. 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.
gossip_guide is provided by the Gossipcat MCP server (gossipcat). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
