Implementation Reference

• src/index.ts:1166-1171 (handler)

  MCP tool handler for 'jira_get_fields' that invokes jiraClient.getFields() and returns the fields as JSON string.

  case "jira_get_fields": {
    const fields = await jiraClient.getFields();
    return {
      content: [{ type: "text", text: JSON.stringify(fields, null, 2) }],
    };
  }

• src/index.ts:520-528 (registration)

  Tool registration in ListTools handler, including name, description, and empty input schema (no parameters required).

  {
    name: "jira_get_fields",
    description:
      "Get all available fields including custom fields - shows field IDs, names, and types",
    inputSchema: {
      type: "object",
      properties: {},
    },
  },

• src/jira-client.ts:389-406 (helper)

  Core implementation of getFields() in JiraClient class, which makes an API request to Jira's /field endpoint to fetch all available fields.

  // Get all fields (including custom fields)
  async getFields(): Promise<
    Array<{
      id: string;
      name: string;
      custom: boolean;
      schema?: { type: string };
    }>
  > {
    return this.request<
      Array<{
        id: string;
        name: string;
        custom: boolean;
        schema?: { type: string };
      }>
    >("/field");
  }
