Overview

MCP server for VictoriaMetrics, enabling data ingestion, querying, and management via PromQL, with potential risks from write operations.

This MCP server provides both read and write access to a VictoriaMetrics database. While querying is generally safe, write operations pose a moderate risk if not properly controlled. Ensure proper input validation and resource limits to mitigate potential abuse.

Performance depends heavily on the complexity of the PromQL queries and the size of the VictoriaMetrics dataset. Indexing and data partitioning are crucial for optimal performance.

Cost is primarily determined by the VictoriaMetrics instance's resource consumption (CPU, memory, disk). Complex queries and high data ingestion rates can increase costs.

Known Risks

!Data injection vulnerabilities via `vm_data_write` and `vm_prometheus_write` if input is not validated.
!Resource exhaustion due to overly broad or complex PromQL queries.
!Exposure of sensitive data through poorly crafted queries.
!Unauthorized data modification or deletion if environment variables are compromised.
!Lack of audit logging makes it difficult to track changes and identify potential security breaches.

Safety Score

moderate risk

Positive

+Query operations are generally safe.
+Clear separation of read and write operations.
+PromQL limits query expressiveness, reducing potential for abuse.
+No inherent code execution capabilities.

Risks

-Write operations (vm_data_write, vm_prometheus_write) can impact data integrity and availability.
-Lack of explicit RBAC in the provided documentation.
-Potential for resource exhaustion through uncontrolled queries.
-Environment variable-based authentication might be vulnerable if not properly managed.

Use Cases

Monitoring and Alerting

-Querying metrics for system health.
-Creating alerts based on metric thresholds.
-Visualizing performance trends over time.

Data Analysis

-Analyzing application performance.
-Identifying bottlenecks in infrastructure.
-Tracking user behavior patterns.

Capacity Planning

-Forecasting resource utilization.
-Identifying potential capacity constraints.
-Optimizing resource allocation.

Who Is This For?

Best For

Monitoring infrastructure and applications.
Analyzing time series data.
Creating custom dashboards and alerts.
Integrating with existing Prometheus-based monitoring systems.

Not Ideal For

Applications requiring strict RBAC and access control.
Environments with untrusted or malicious users.
Tasks requiring complex data transformations or aggregations beyond PromQL capabilities.

Autonomy & Execution

Default ModeRead and Write enabled

Sandboxed

Autonomy is limited by the capabilities exposed through the MCP tools. The agent can query and write data, but cannot perform administrative tasks or execute arbitrary code.

StatelessYes

Retry LogicNot documented

ConcurrencyNot documented

Production Tip

Implement rate limiting and query complexity limits to prevent resource exhaustion and ensure stability.

FAQ

What authentication methods are supported?

Authentication is based on environment variables (VM_URL, VM_SELECT_URL, VM_INSERT_URL). Ensure these are securely managed.

How can I limit the resources consumed by queries?

Implement query timeouts and complexity limits in your VictoriaMetrics instance.

Is it safe to expose this MCP server to the internet?

No, it is not recommended. Expose it only within a trusted network and consider using a reverse proxy with authentication.

How do I monitor the performance of this MCP server?

Monitor the resource usage (CPU, memory) of the Node.js process running the server.

Can I use this server to delete data from VictoriaMetrics?

No, there is no explicit delete functionality exposed in the provided documentation. However, data can be overwritten using write operations.

What versions of VictoriaMetrics are supported?

The documentation does not specify supported versions. Compatibility should be tested with your specific VictoriaMetrics deployment.

How are errors handled?

Errors from VictoriaMetrics are likely propagated back to the client. Implement proper error handling in your client application.
