Search user facts
AI agents call search_facts to retrieve information from Spiderchat without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search query to retrieve facts, which is a read-only operation that retrieves data without side effects. There is no indication of data modification, deletion, or execution of external operations. The semantic search context from the server description further supports this as a data retrieval capability.
From the tool's definition Tool name 'search_facts' and description 'Search user facts' indicate a retrieval operation with no modification or execution capability.

Search user facts. It is categorised as a Read tool in the Spiderchat MCP Server, which means it retrieves data without modifying state.
Register the Spiderchat MCP server in PolicyLayer and add a rule for search_facts: 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 Spiderchat. Nothing to install.
search_facts 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 search_facts 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 search_facts. 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.
search_facts is provided by the Spiderchat MCP server (spider-chat/spiderchat-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
