Implementation Reference
- src/server.ts:740-753 (handler)The primary handler function for the 'edit-draft' tool. It destructures input parameters, calls zulipClient.editDraft to perform the update, and returns success/error responses.async ({ draft_id, type, to, topic, content, timestamp }) => { try { await zulipClient.editDraft(draft_id, { type, to, topic, content, timestamp }); return createSuccessResponse(`Draft ${draft_id} updated successfully!`); } catch (error) { return createErrorResponse(`Error editing draft: ${error instanceof Error ? error.message : 'Unknown error'}`); } }
- src/types.ts:229-236 (schema)Zod schema that validates and describes the input parameters for the 'edit-draft' tool.export const EditDraftSchema = z.object({ draft_id: z.number().describe("Unique draft ID to edit"), type: z.enum(["stream", "direct"]).describe("Draft message type"), to: z.array(z.number()).describe("Array of user IDs or channel ID"), topic: z.string().describe("Topic for the draft"), content: z.string().describe("Draft content"), timestamp: z.number().optional().describe("Updated timestamp") });
- src/server.ts:736-754 (registration)Registers the 'edit-draft' tool with the MCP server, including name, description, input schema, and handler function.server.tool( "edit-draft", "Update an existing message draft. For user IDs in the 'to' field, use the users-directory resource (zulip://users) or get-users tool to discover available users and their IDs.", EditDraftSchema.shape, async ({ draft_id, type, to, topic, content, timestamp }) => { try { await zulipClient.editDraft(draft_id, { type, to, topic, content, timestamp }); return createSuccessResponse(`Draft ${draft_id} updated successfully!`); } catch (error) { return createErrorResponse(`Error editing draft: ${error instanceof Error ? error.message : 'Unknown error'}`); } } );
- src/zulip/client.ts:321-329 (helper)ZulipClient helper method that makes the actual PATCH request to Zulip's /drafts/{draftId} API endpoint to edit the draft.async editDraft(draftId: number, params: { type: 'stream' | 'direct'; to: number[]; topic: string; content: string; timestamp?: number; }): Promise<void> { await this.client.patch(`/drafts/${draftId}`, params); }
