# AX MCP Tool Catalog

> Every tool the Arize AX MCP server exposes, grouped by resource.

The server exposes 45 read-only tools, plus `server_info`. Each one wraps a single [REST API v2](/docs/ax/rest-reference/overview) operation and takes the same arguments as the endpoint behind it, so the [endpoint reference](/docs/ax/rest-reference/overview) is the place to look for full response schemas.

<Note>
  Every tool listed here is currently read-only. There are no create, update, or delete tools.
</Note>

See [conventions](/docs/api-clients/mcp/conventions) for the pagination, span limit, timeout, and error rules shared across every tool below.

## Projects

Projects are the usual entry point. An agent that knows your project ID can reach traces, spans, and tasks from there.

| Tool                | Description                         |
| ------------------- | ----------------------------------- |
| `list_projects`     | List projects the caller can access |
| `get_project`       | Read one project by ID or name      |
| `list_project_tags` | List tags on a project              |

## Traces and spans

| Tool          | Description              |
| ------------- | ------------------------ |
| `list_traces` | List traces in a project |
| `list_spans`  | List spans in a project  |

Point your agent at a specific trace when you are debugging. Asking it to list spans across a busy project without filters will burn through pages and tell you very little.

## Datasets

| Tool                    | Description                              |

## Experiments

| Tool                   | Description                       |

| `list_experiments`     | List experiments for a dataset    |
| `get_experiment`       | Read one experiment               |
| `list_experiment_runs` | Page through an experiment's runs |
| `list_experiment_tags` | List tags on an experiment        |

## Evaluators

| `get_evaluator_version`    | Read one evaluator version            |
| `list_evaluator_templates` | List the built-in evaluator templates |
| `list_evaluator_tags`      | List tags on an evaluator             |

## Annotations

| `list_annotation_queue_records` | Page through the records in a queue |
| `list_annotation_queue_tags`    | List tags on an annotation queue    |

## Prompts

| Tool                   | Description                                         |

## What is not here

There are no create, update, or delete tools, and the account administration surface is left out entirely, including API keys, users, roles, and role bindings. For those, and for anything that writes, use [Arize Skills](/docs/ax/skills/overview) or the [CLI](/docs/api-clients/cli/overview).
