# Search Registration Flows

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

Search published registration flows (forms) in the caller's organization by event ID, flow IDs, and/or name (case-insensitive substring). Results are always scoped to the caller's organization. Returns each matching flow's flowId and name. Use a returned flowId with a flowId filter on search_attendees / search_attendee_count to scope attendees to a specific registration flow.

**MCP-only:** this tool has no equivalent Public API endpoint.

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.
