Jira MCP Server

Instructions

Implementation Reference

• src/index.ts:1140-1146 (handler)

  MCP tool handler case that validates input using GetEditMetaSchema, calls jiraClient.getEditMeta, and returns the metadata as JSON.

  case "jira_get_edit_meta": {
    const { issueKey } = GetEditMetaSchema.parse(args);
    const meta = await jiraClient.getEditMeta(issueKey);
    return {
      content: [{ type: "text", text: JSON.stringify(meta, null, 2) }],
    };
  }

• src/index.ts:129-131 (schema)

  Zod schema used for input validation in the tool handler.

  const GetEditMetaSchema = z.object({
    issueKey: z.string().describe("The Jira issue key to get edit metadata for"),
  });

• src/index.ts:475-489 (registration)

  Tool registration entry in the ListToolsRequestHandler, defining name, description, and input schema.

  {
    name: "jira_get_edit_meta",
    description:
      "Get metadata for editing an issue - shows editable fields and allowed values for an existing issue",
    inputSchema: {
      type: "object",
      properties: {
        issueKey: {
          type: "string",
          description: "The Jira issue key to get edit metadata for",
        },
      },
      required: ["issueKey"],
    },
  },

• src/jira-client.ts:365-367 (helper)

  JiraClient helper method that makes the REST API call to /rest/api/2/issue/{issueKey}/editmeta to fetch edit metadata.

  async getEditMeta(issueKey: string): Promise<unknown> {
    return this.request<unknown>(`/issue/${issueKey}/editmeta`);
  }
