Load the knowledge wiki catalog at session start. Returns article metadata grouped by category. Pass story_id when working on a loopctl story so reads attribute correctly.
Part of the Loopctl MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke knowledge_index to trigger processes or run actions in Loopctl. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
knowledge_index can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

knowledge_index is one of the high-risk operations in Loopctl. For the full severity-focused view — only the high-risk tools with their recommended policies — see the breakdown for this server, or browse all high-risk tools across every MCP server.
Load the knowledge wiki catalog at session start. Returns article metadata grouped by category. Pass story_id when working on a loopctl story so reads attribute correctly.. It is categorised as a Execute tool in the Loopctl MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for knowledge_index. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Loopctl MCP server.
knowledge_index is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the knowledge_index rule in your Intercept 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 Intercept policy for knowledge_index. 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.
knowledge_index is provided by the Loopctl MCP server (loopctl-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
