Generates an Alloy loki.process snippet enforcing an approved label set via stage.label_keep, with optional log-level normalisation and soft-enforcement placeholders.
AI agents use suggest_loki_alloy_label_config to create or update resources in Mcp Grafana Npx — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Grafana Npx environment.

|---|---|---|---|
forwardTo | string | — | |
componentName | string | — | |
approvedLabels | array | Yes | Labels to keep on the index. |
requiredLabels | array | — | Labels that get an 'unknown' placeholder when missing. |
normalizeLogLevel | boolean | — |
Parameters from the server's own tool schema.
This tool generates configuration code (Alloy loki.process snippets) which constitutes creating/modifying data reversibly. While it produces configuration that will be applied to log processing pipelines, the tool itself only generates the snippet—it does not directly execute against infrastructure or delete data.
From the tool's definition Generates an Alloy loki.process snippet...via stage.label_keep, with optional log-level normalisation and soft-enforcement placeholders. The tool creates/modifies Loki/Alloy configuration artifacts.
Attacks that exploit this kind of access
Generates an Alloy loki.process snippet enforcing an approved label set via stage.label_keep, with optional log-level normalisation and soft-enforcement placeholders. It is categorised as a Write tool in the Mcp Grafana Npx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
suggest_loki_alloy_label_config accepts 5 parameters: forwardTo, componentName, approvedLabels, requiredLabels, normalizeLogLevel. Required: approvedLabels. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Grafana Npx MCP server in PolicyLayer and add a rule for suggest_loki_alloy_label_config: 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 Mcp Grafana Npx. Nothing to install.
suggest_loki_alloy_label_config 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 suggest_loki_alloy_label_config 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 suggest_loki_alloy_label_config. 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.
suggest_loki_alloy_label_config is provided by the Mcp Grafana Npx MCP server (mcp-grafana-npx). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
