Part of the Knowledge Graph Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use update_resource to create or modify resources in Knowledge Graph Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call update_resource repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Knowledge Graph Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Update resource information in the knowledge graph. This tool must be used in conjunction with list_graphs and get_node_details tools. Use cases: 1. Modify resource title or description 2. Update resource metadata information 3. Improve resource documentation Usage recommendations: 1. First call list_graphs to get target graph information 2. Use get_node_details to check current resource information 3. Only update fields that need to be modified 4. Maintain consistency in resource naming Return data: - data: Updated resource information * id: Resource ID * name: Resource name * title: Resource title * description: Resource description * updatedAt: Update time. It is categorised as a Write tool in the Knowledge Graph Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for update_resource. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Knowledge Graph Server MCP server.
update_resource is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_resource 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 update_resource. 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.
update_resource is provided by the Knowledge Graph Server MCP server (aiuluna/knowledge-graph-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
