Only the name is required. This call does NOT take a logo or cover image: create the sponsor, then call v1_upload_sponsor_image with the returned sponsor id. On events where the exhibitor portal is enabled the organization's plan is checked first, so this can fail with a 403 naming the sponsor limit โ€” that is a plan problem, not a bad request. Returns the created sponsor. **Same as Public API:** [Create a sponsor](/api-reference/sponsors/create-a-sponsor) (`POST /v1/events/{eventId}/sponsors`) ## OpenAPI ````yaml https://api.prod.zuddl.com/api/v3/api-docs/mcp-tools post /tools/v1_create_sponsor openapi: 3.1.0 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/` paths in this reference identify tools; they are not HTTP endpoints. # Behaviour labels | Label | Meaning | | --- | --- | | ๐Ÿ”’ Read-only | Reads data and changes nothing. | | โœ๏ธ Write | Creates or updates data, but does not delete it. | | โš ๏ธ Destructive | Deletes or removes data. Most assistants ask you to approve these calls. | | ๐Ÿ” 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. version: 1.0.0 servers: - url: https://setup.zuddl.com/api/mcp description: Zuddl MCP server security: - oauth: [] tags: - name: Events - name: Attendees - name: Sessions - name: Speakers - name: Sponsors - name: Locations - name: Teams - name: Brand Kits - name: Registration flows & tickets - name: Analytics paths: /tools/v1_create_sponsor: post: tags: - Sponsors summary: Create Sponsor description: >- **Tool name:** `v1_create_sponsor` ยท **Behaviour:** โœ๏ธ Write Add a sponsor to an event in your Zuddl organization.
