# Toolsets

The Kloudfuse MCP server groups its tools into **toolsets** so you can expose only the ones you need on a given connection. Selecting fewer toolsets keeps the AI assistant’s context window small, which often improves answer quality and reduces token cost.

By default the server exposes every tool — selecting toolsets is opt-in, useful when you want a smaller, task-specific surface (for example, only `apm` and `logs` for trace-driven investigations).

## Available Toolsets

| Toolset       | What it covers                                                                                           |
|---------------|---------------------------------------------------------------------------------------------------------|
| `metrics`     | Run PromQL queries against your metrics, list label names, and explore label values.                     |
| `logs`       | Search logs, list log labels and values, and run LogQL metric queries over log data.                    |
| `apm`        | Inspect APM services and dependencies, search and drill into traces, view trace waterfalls and span details, and surface trace errors. |
| `alerts`     | Search alert rules, fetch the underlying queries, and pull alert firing history.                         |
| `events`     | Query Kubernetes events with filtering, sorting, and facet discovery.                                   |
| `infrastructure` | Search Kubernetes objects (pods, deployments, services, nodes, …​) and get their current status.       |
| `pyroscope`   | Pull continuous-profiling data: profile types, label discovery, time series, flamegraphs, and diff comparisons between profiles. |
| `rum`        | Real User Monitoring — list applications, search RUM events, view error groups, fetch latency distributions and time series, and unminify stack traces. |
| `docs`       | Search and retrieve official Kloudfuse documentation pages.                                           |

## Selecting Toolsets

Append a `toolsets` query parameter to the MCP server URL with a comma-separated list of names:

```
https://<KLOUDFUSE_URL>/mcp?toolsets=apm,logs
```

The order of names does not matter. Whitespace around names is tolerated.

|     |     |
| --- | --- |
|     | Define multiple MCP server entries against the same Kloudfuse cluster — each with its own toolset — and assign them to different subagents or workflows. For example, an incident-triage subagent can use a connection scoped to `logs,metrics,alerts`, while a performance-tuning subagent uses one scoped to `apm,pyroscope`. Most MCP clients let you give each entry a separate name. |

Use this URL anywhere your MCP client accepts an MCP server endpoint — the same places shown in [Install MCP Server in Kloudfuse](https://docs.kloudfuse.com/platform/latest/ai-ml/mcp-server/remote-instructions/) and the [OAuth custom connector](https://docs.kloudfuse.com/platform/latest/ai-ml/mcp-server/oauth/overview/) guides. When passing the URL on a command line, quote it to prevent shell globbing or word-splitting of query characters.

## Notes

- **Applies to the remote MCP server only.** Toolset selection is read from the URL query string, so it works for the cluster-hosted server at `https://<KLOUDFUSE_URL>/mcp` and for OAuth custom connectors. The local Docker container exposes its full toolset.

- **Unknown names are ignored.** Misspelled or unsupported names are silently dropped from your selection so future toolset additions and renames stay backward compatible. Double-check the spelling against the table above if a tool you expect is not appearing.

- **Changing toolsets requires reconnecting.** Update the URL in your MCP client and restart or reconnect the connector for the new selection to take effect.
