# List Tags

> **Tool name:** `v1_list_tags` · **Behaviour:** 🔒 Read-only

List the event tags defined in the user's Zuddl organization, paginated. Call this before v1_create_event when the user names a tag: tagNames is matched against these exactly, and tags are never created automatically, so a name that is not here is rejected. Pass q to search by name. pagination.next is non-null when another page exists — call again with the next page number until it is null.

**Same as Public API:** [Get the organization's event tags](/api-reference/events/get-the-organizations-event-tags) (`GET /v1/events/tags`)

info:
  title: Zuddl MCP Tools Reference
  description: >-
    The Zuddl MCP server lets AI assistants such as Claude and ChatGPT work with
    your Zuddl organization through the [Model Context
    Protocol](https://modelcontextprotocol.io). This reference lists every tool
    the server offers. It is generated from the live server, so it always
    matches what your assistant sees.


    # Connecting


    Add `https://setup.zuddl.com/api/mcp` as a remote MCP server in your
    assistant. It signs you in to Zuddl with OAuth and then calls tools on your
    behalf, with your permissions. AI features must be enabled for your
    organization.


    # Calling a tool


    Assistants call a tool with a JSON-RPC `tools/call` request whose `name` is
    the tool name and whose `arguments` match the request body documented on the
    tool's page. The `/tools/<name>` paths in this reference identify tools;
    they are not HTTP endpoints.


    # Behaviour labels


    | Label | Meaning |

    | --- | --- |

    | 🔒 Read-only | Reads data and changes nothing. |

    | ✏️ Write | Creates or updates data, but does not delete it. |

    | ⚠️ Destructive | Deletes or removes data. Most assistants ask you to
    approve these calls. |

    | 🔁 Idempotent | Calling it again with the same arguments has no further
    effect. |


    A tool that mirrors a Public API endpoint links to that endpoint's page.
    MCP-only tools have no Public API equivalent.
