Zendesk API MCP Server

Implementation Reference

• src/tools/triggers.js:124-146 (handler)

  The main handler function for the "update_trigger" MCP tool. It optionally builds triggerData from provided inputs and delegates to zendeskClient.updateTrigger, handling success/error responses.
  handler: async ({ id, title, description, conditions, actions }) => { try { const triggerData = {}; if (title !== undefined) triggerData.title = title; if (description !== undefined) triggerData.description = description; if (conditions !== undefined) triggerData.conditions = conditions; if (actions !== undefined) triggerData.actions = actions; const result = await zendeskClient.updateTrigger(id, triggerData); return { content: [{ type: "text", text: `Trigger updated successfully!\n\n${JSON.stringify(result, null, 2)}` }] }; } catch (error) { return { content: [{ type: "text", text: `Error updating trigger: ${error.message}` }], isError: true }; } }
• src/tools/triggers.js:103-123 (schema)

  Zod input schema for the "update_trigger" tool defining parameters: required id, optional title, description, conditions (all/any), and actions.
  schema: { id: z.number().describe("Trigger ID to update"), title: z.string().optional().describe("Updated trigger title"), description: z.string().optional().describe("Updated trigger description"), conditions: z.object({ all: z.array(z.object({ field: z.string().describe("Field to check"), operator: z.string().describe("Operator for comparison"), value: z.any().describe("Value to compare against") })).optional(), any: z.array(z.object({ field: z.string().describe("Field to check"), operator: z.string().describe("Operator for comparison"), value: z.any().describe("Value to compare against") })).optional() }).optional().describe("Updated conditions"), actions: z.array(z.object({ field: z.string().describe("Field to modify"), value: z.any().describe("Value to set") })).optional().describe("Updated actions") },
• src/server.js:31-52 (registration)

  Registration of triggersTools (containing "update_trigger") by spreading into allTools array and registering each via server.tool(name, schema, handler).
  const allTools = [ ...ticketsTools, ...usersTools, ...organizationsTools, ...groupsTools, ...macrosTools, ...viewsTools, ...triggersTools, ...automationsTools, ...searchTools, ...helpCenterTools, ...supportTools, ...talkTools, ...chatTools, ]; // Register each tool with the server allTools.forEach((tool) => { server.tool(tool.name, tool.schema, tool.handler, { description: tool.description, }); });
• src/zendesk-client.js:220-222 (helper)

  Low-level helper method in ZendeskClient that performs the actual API PUT request to update a trigger.
  async updateTrigger(id, data) { return this.request("PUT", `/triggers/${id}.json`, { trigger: data }); }
