Update a single Kibana saved object by type and ID. This performs a partial update - only the specified attributes will be changed, other attributes remain unchanged. Supports all saved object types (dashboard, visualization, index-pattern, search, config, lens, map, tag, canvas-workpad, canvas-e...

Part of the Kibana MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use vl_update_saved_object to create or modify resources in Kibana. 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 vl_update_saved_object 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 Kibana.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Update a single Kibana saved object by type and ID. This performs a partial update - only the specified attributes will be changed, other attributes remain unchanged. Supports all saved object types (dashboard, visualization, index-pattern, search, config, lens, map, tag, canvas-workpad, canvas-element, etc.). IMPORTANT: Use version parameter for optimistic concurrency control to prevent conflicts.. It is categorised as a Write tool in the Kibana 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 vl_update_saved_object. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Kibana MCP server.
vl_update_saved_object 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 vl_update_saved_object 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 vl_update_saved_object. 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.
vl_update_saved_object is provided by the Kibana MCP server (@tocharianou/mcp-server-kibana). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
