GitLab MCP Server

Instructions

Implementation Reference

• src/api/milestones.ts:83-93 (handler)

  The handler function that performs the actual API call to delete a milestone in GitLab.

  export async function deleteMilestone(projectId: string, milestoneId: number): Promise<void> {
    if (!projectId?.trim()) {
      throw new Error("Project ID is required");
    }
    if (!milestoneId || milestoneId < 1) {
      throw new Error("Valid milestone ID is required");
    }
  
    const endpoint = `/projects/${encodeProjectId(projectId)}/milestones/${milestoneId}`;
    await gitlabDelete(endpoint);
  }

• src/schemas.ts:337-340 (schema)

  Zod schema for validating the input arguments for delete_milestone.

  export const DeleteMilestoneSchema = z.object({
    project_id: z.string(),
    milestone_id: z.number()
  });

• src/server.ts:145-148 (registration)

  Registration of the delete_milestone tool in the MCP server.

    name: "delete_milestone",
    description: "Delete a milestone from a GitLab project",
    inputSchema: zodToJsonSchema(DeleteMilestoneSchema)
  },

• src/server.ts:351-355 (handler)

  The request handler logic that dispatches the tool call to the API function.

  case "delete_milestone": {
    const args = DeleteMilestoneSchema.parse(request.params.arguments);
    await api.deleteMilestone(args.project_id, args.milestone_id);
    return { content: [{ type: "text", text: JSON.stringify({ success: true }, null, 2) }] };
  }
