A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.

The implementation of Model Context Protocol (MCP) server for VictoriaMetrics.
This provides access to your VictoriaMetrics instance and seamless integration with VictoriaMetrics APIs and documentation. It can give you a comprehensive interface for monitoring, observability, and debugging tasks related to your VictoriaMetrics instances, enable advanced automation and interaction capabilities for engineers and tools.
This MCP server allows you to use almost all read-only APIs of VictoriaMetrics, i.e. all functions available in VMUI:
In addition, the MCP server contains embedded up-to-date documentation and is able to search it without online access.
image
More details about the exact available tools and prompts can be found in the Usage section.
You can combine functionality of tools, docs search in your prompts and invent great usage scenarios for your VictoriaMetrics instance. Just check the Dialog example section to see how it can work. And please note the fact that the quality of the MCP Server and its responses depends very much on the capabilities of your client and the quality of the model you are using.
You can also combine the MCP server with other observability or doc search related MCP Servers and get even more powerful results.
There is a publicly available instance of the VictoriaMetrics MCP Server that you can use to test the features without installing it:
https://play-mcp.victoriametrics.com/mcpAttention! This URL is not supposed to be opened in a browser, it is intended to be used in MCP clients.
It's available in Streamable HTTP mode and configured to work with Public VictoriaMetrics Playground.
Here is example of configuration for Claude Desktop:
Just download the latest release from Releases page and put it to your PATH.
Example for Linux x86_64 (note that other architectures and platforms are also available):
latest=$(curl -s https://api.github.com/repos/VictoriaMetrics/mcp-victoriametrics/releases/latest | grep 'tag_name' | cut -d\" -f4)
wget https://github.com/VictoriaMetrics/mcp-victoriametrics/releases/download/$latest/mcp-victoriametrics_Linux_x86_64.tar.gz
tar axvf mcp-victoriametrics_Linux_x86_64.tar.gzYou can run VictoriaMetrics MCP Server using Docker.
This is the easiest way to get started without needing to install Go or build from source.
docker run -d --name mcp-victoriametrics \
-e VM_INSTANCE_ENTRYPOINT=https://play.victoriametrics.com \
-e VM_INSTANCE_TYPE=cluster \
-e MCP_SERVER_MODE=sse \
-e MCP_LISTEN_ADDR=:8080 \
-e MCP_AUTH_TOKEN=your-secret-token \
-p 8080:8080 \
ghcr.io/victoriametrics/mcp-victoriametricsYou should replace environment variables with your own parameters.
Note that the MCP_SERVER_MODE=http flag is used to enable Streamable HTTP mode. More details about server modes can be found in the Configuration section.
See available docker images in github registry.
Also see Using Docker instead of binary section for more details about using Docker with MCP server with clients in stdio mode.
For building binary from source code you can use the following approach:
git clone https://github.com/VictoriaMetrics/mcp-victoriametrics.git
cd mcp-victoriametrics make build
# after that you can find binary mcp-victoriametrics and copy this file to your PATH or run inplace docker build -t mcp-victoriametrics .
# after that you can use docker image mcp-victoriametrics for running or pushingCheck out VictoriaMetrics MCP Server Helm chart documentation for more details about installation using Helm.
MCP Server for VictoriaMetrics is configured via environment variables:
| Variable | Description | Required | Default | Allowed values |

You can use two options to connect to your VictoriaMetrics instance:
VM_INSTANCE_ENTRYPOINT + VM_INSTANCE_TYPE + VM_INSTANCE_BEARER_TOKEN (optional) environment variables to connect to any single-node or cluster instance of VictoriaMetrics.VMC_API_KEY environment variable to work with your VictoriaMetrics Cloud instances.MCP Server supports the following modes of operation (transports):
stdio - Standard input/output mode, where the server reads commands from standard input and writes responses to standard output. This is the default mode and is suitable for local servers.sse - Server-Sent Events. Server will expose the /sse and /message endpoints for SSE connections.http - Streamable HTTP. Server will expose the /mcp endpoint for HTTP connections.More info about traqnsports you can find in MCP docs:
# For a single-node instance

Here is an example of a real dialog with the Assistant using the MCP Server with Claude Desktop, configured to work with the public playground instance. It shows how the server can help in practice.
👤 You: What tenants are available in my VM?
🤖 In your VictoriaMetrics instance, the following tenants are available0:0(default tenant),1:0,10:0,100:0
👤 You: From now on, please use only default tenant
🤖 I understand. From now on, I'll use only the default tenant (0:0) for all operations with your VictoriaMetrics instance.
👤 You: Which metrics do we have?
🤖 There are many metrics available in your VictoriaMetrics instance. The list includes metrics from various systems and components, such as:
>
- System metrics (node_,machine_, etc.), - Kubernetes metrics (kube_,container_,apiserver_, etc.), - VictoriaMetrics-specific metrics (vm_,vmagent_,vmalert_, etc.), - Go runtime metrics (go_), - Prometheus-related metrics (scrape_,promhttp_), - Various application metrics (argocd_,alertmanager_).
>
This is a comprehensive list of over 2000 metrics that are available for querying. Is there a specific type of metric you're interested in exploring further?
👤 You: Ok, let's work with kubernetes metrics from now on. Please show me which of these metrics never queried?
🤖 Based on the results, I can see that there are two Kubernetes metrics that have never been queried (query count is 0):
>
-kube_persistentvolumeclaim_deletion_timestamp- This metric provides information about when PersistentVolumeClaims were marked for deletion. -kube_pod_init_container_status_last_terminated_reason- This metric shows the reason why init containers in pods were last terminated.
>
These metrics might be valuable for monitoring and troubleshooting purposes:
>
- The PVC deletion timestamp metric could help track deletion patterns or identify stuck PVCs. - The init container termination reason metric could help identify common failure patterns in your initialization containers.
>
Would you like me to explain more about what these metrics track or suggest some useful queries to start monitoring them?
👤 You: Yes, please. And also, can you create relabeling rules to stop ingesting these metrics?
🤖 I'll create a relabel configuration to exclude these never-queried metrics from collection. This will help reduce storage and processing overhead. Here's the relabel configuration you can add to your VictoriaMetrics scrape configuration:

``yaml relabel_configs: - action: drop source_labels: [__name__] regex: kube_persistentvolumeclaim_deletion_timestamp|kube_pod_init_container_status_last_terminated_reason ``>
This configuration will: 1. Look at each metric's name (the __name__ label) 2. Check if it matches either of the specified metrics 3. Drop the metrics that match, preventing them from being collected and stored>
You can add this to your VictoriaMetrics configuration file or to the relevant scrape job configurations in your Prometheus configuration if you're using Prometheus as a scraper for VictoriaMetrics. If you want to test this relabel configuration before implementing it, you can use the metric relabel debug tool to see how it would affect your metrics.
👤 You: Yes, please debug this relabel config on real time series to see how it would affect my metrics
🤖 Perfect! The relabel config works as expected:
>
- The first two test cases show that bothkube_persistentvolumeclaim_deletion_timestampandkube_pod_init_container_status_last_terminated_reasonmetrics are correctly dropped (resulting labels are empty{}). - The third test case confirms that other metrics likekube_pod_status_phaseare preserved and not affected by our drop rule.

You can confidently add this relabel configuration to your VictoriaMetrics or Prometheus configuration to stop collecting these unused metrics. This will save storage space and reduce processing overhead without affecting your current monitoring capabilities.
👤 You: But i'm using vmagent resource of VictoriaMetrics operator, could you please give me part of specification for my agent with this relabel config?
🤖 You're right, since you're using the VictoriaMetrics Operator and the VMAgent custom resource, the configuration needs to be in the appropriate format for that CR. Here's how you can add the relabel configuration to your VMAgent specification:
>
```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMAgent metadata: name: your-vmagent-name spec: # ... your existing configuration ...
>
# Add this section to configure global metric relabeling inlineRelabelConfig: - action: drop sourceLabels: ["__name__"] regex: kube_persistentvolumeclaim_deletion_timestamp|kube_pod_init_container_status_last_terminated_reason
>
# ... rest of your configuration ... ```
>
Key points:
>
- In the VMAgent spec, you useinlineRelabelConfigfor inline relabeling rules - The field is calledsourceLabels(notsource_labelsas in Prometheus config) - This is a global relabeling that will be applied to all metrics before they're stored
👤 You: I decided not to remove those metrics, but just lower the sample rate for them using Downsampling. What downsampling parameters i have now?
🤖 I can see that you currently have the following downsampling configuration:
>
`` -downsampling.period="7d:1m,30d:5m,180d:30m" ``>
This means:
>
- Data newer than 7 days is kept at its original resolution - Data between 7-30 days old is downsampled to 1-minute resolution - Data between 30-180 days old is downsampled to 5-minute resolution - Data older than 180 days is downsampled to 30-minute resolution
>
Now, if you want to add specific downsampling rules for those rarely-queried metrics, you can use the downsampling filters debug tool to test how new rules would work. Let's test a configuration where we apply more aggressive downsampling to those specific metrics:
>
...getting series and using downsampling filter debugger...

Great! Now our test is working correctly. Based on the current configuration and our testing, here's a suggested downsampling configuration for your VMAgent CR that would apply more aggressive downsampling to those rarely-queried metrics:
>
```yaml apiVersion: operator.victoriametrics.com/v1beta1 kind: VMCluster metadata: name: monitoring-vm-cluster spec: # ... your existing configuration ...
>
# Update the vmstorage section with the new downsampling parameters vmstorage: extraArgs: downsampling.period: '{__name__=\"kube_persistentvolumeclaim_deletion_timestamp\"}:1d:10m,{__name__=\"kube_pod_init_container_status_last_terminated_reason\"}:1d:10m,7d:1m,30d:5m,180d:30m'
>
# ... rest of your configuration ... ```
>
This configuration:
>
- Applies 10-minute resolution downsampling for the rarely-queried metrics after just 1 day - Maintains your existing downsampling policy for all other metrics
>
The order of the downsampling rules is important - more specific rules should be listed first.

In SSE and HTTP modes the MCP Server provides metrics in Prometheus format (see endpoints) and you can find in repo simple grafana dashboard for these metrics.
The server contains an embedded vector database with VictoriaMetrics documentation and blog posts for the documentation tool. It helps to answer complex questions about VictoriaMetrics without providing all data to LLM. This is the main source of resource usage. To reduce it, add documentation to MCP_DISABLED_TOOLS environment variable to completely disable the vector database loading.
You can use MCP_PASSTHROUGH_HEADERS parameter in the MCP Server together with Header-based routing in vmauth to route MCP calls between instances based on HTTP header values from your MCP client config.
v0.0.5)v0.0.6)v1.0.0)v0.0.7)v0.0.9)v1.1.0)v0.0.8)AI services and agents along with MCP servers like this cannot guarantee the accuracy, completeness and reliability of results. You should double check the results obtained with AI.
The quality of the MCP Server and its responses depends very much on the capabilities of your client and the quality of the model you are using.
