Zulip MCP Server

Instructions

Implementation Reference

• src/server.ts:916-932 (handler)

  MCP tool handler function that executes the remove-emoji-reaction logic by calling the Zulip client's removeReaction method and handling responses/errors.
  server.tool( "remove-emoji-reaction", "Remove an emoji reaction from a message.", RemoveReactionSchema.shape, async ({ message_id, emoji_name, emoji_code, reaction_type }) => { try { await zulipClient.removeReaction(message_id, { emoji_name, emoji_code, reaction_type }); return createSuccessResponse(`Reaction ${emoji_name} removed from message ${message_id}!`); } catch (error) { return createErrorResponse(`Error removing reaction: ${error instanceof Error ? error.message : 'Unknown error'}`); } } );
• src/types.ts:205-210 (schema)

  Zod schema defining input parameters for the remove-emoji-reaction tool, used for validation.
  export const RemoveReactionSchema = z.object({ message_id: z.number().describe("ID of the message to remove reaction from"), emoji_name: z.string().describe("Emoji name to remove (e.g., 'thumbs_up', 'heart')"), emoji_code: z.string().optional().describe("Unicode code point for the emoji"), reaction_type: z.enum(["unicode_emoji", "realm_emoji", "zulip_extra_emoji"]).optional().describe("Type of emoji reaction") });
• src/server.ts:916-932 (registration)

  Registration of the remove-emoji-reaction tool in the MCP server using server.tool().
  server.tool( "remove-emoji-reaction", "Remove an emoji reaction from a message.", RemoveReactionSchema.shape, async ({ message_id, emoji_name, emoji_code, reaction_type }) => { try { await zulipClient.removeReaction(message_id, { emoji_name, emoji_code, reaction_type }); return createSuccessResponse(`Reaction ${emoji_name} removed from message ${message_id}!`); } catch (error) { return createErrorResponse(`Error removing reaction: ${error instanceof Error ? error.message : 'Unknown error'}`); } } );
• src/zulip/client.ts:214-225 (helper)

  ZulipClient helper method that performs the actual API DELETE request to remove the emoji reaction from Zulip.
  async removeReaction(messageId: number, params: { emoji_name: string; emoji_code?: string; reaction_type?: string; }): Promise<void> { const queryParams = new URLSearchParams(); queryParams.append('emoji_name', params.emoji_name); if (params.emoji_code) {queryParams.append('emoji_code', params.emoji_code);} if (params.reaction_type) {queryParams.append('reaction_type', params.reaction_type);} await this.client.delete(`/messages/${messageId}/reactions?${queryParams.toString()}`); }
