Jira Api Wrapper

An MCP server (stdio) that talks directly to Jira Cloud REST API v3 using static credentials (no OAuth flow) and exposes a small set of deterministic tools for:

• discovering customfield_* IDs
• resolving accountId for user picker fields
• updating issue fields (including ADF JSON)

Testing

Running Tests

Unit and Contract Tests (default, no network):

npm test

This runs all unit tests and contract tests without making any network calls. These tests use mocked HTTP clients and are deterministic.

Integration Tests (requires Jira credentials):

Integration tests make real HTTP calls to Jira Cloud. They are split into read-only (smoke) and write tests.

Read-only smoke tests:

npm run test:integration:smoke

Requires:

• JIRA_BASE_URL (or JIRA_URL)
• JIRA_EMAIL and JIRA_API_TOKEN, OR JIRA_BEARER_TOKEN

Optional variables:

• JIRA_TEST_USER_QUERY: User search query
• JIRA_TEST_JQL: JQL query for search test
• JIRA_TEST_ISSUE_KEY: Issue key for get/transitions tests

Write tests (creates real data):

JIRA_INTEGRATION_WRITE_TESTS=1 npm run test:integration:write

Requires:

• All smoke test variables
• JIRA_TEST_PROJECT_KEY: Project key for creating test issues
• JIRA_TEST_TRANSITION_ID (optional): Transition ID for transition test

⚠️ Warning: Write tests create real issues and comments in your Jira instance. They use the tag [mcp-wrapper-test] in summaries for easy identification and cleanup.

All integration tests:

npm run test:integration

Test Structure

• tests/unit/: Unit tests for individual components (no network)
• tests/contract/: Contract tests for MCP tool handlers (no network, uses fake Jira client)
• tests/integration/smoke.test.js: Read-only integration tests
• tests/integration/write.test.js: Write integration tests (guarded by env var)

Configuration

Set environment variables (pick one auth method):

Mapping from ga-jira/mcp.json

• JIRA_URL → JIRA_BASE_URL (same value)
• JIRA_EMAIL → JIRA_EMAIL
• JIRA_API_TOKEN → JIRA_API_TOKEN

Option A: Basic auth (Jira Cloud email + API token)

• JIRA_BASE_URL (example: https://your-domain.atlassian.net)
• JIRA_EMAIL (example: [email protected])
• JIRA_API_TOKEN (create in Atlassian account settings)

Option B: Bearer token

• JIRA_BASE_URL
• JIRA_BEARER_TOKEN

Cursor MCP config example

Add to your Cursor MCP config (typically ~/.cursor/mcp.json):

{
  "mcpServers": {
    "jira-api-mcp-wrapper": {
      "command": "node",
      "args": [
        "/path/to/jira-api-mcp-wrapper/dist/index.js"
      ],
      "env": {
        "JIRA_BASE_URL": "https://your-domain.atlassian.net",
        "JIRA_EMAIL": "[email protected]",
        "JIRA_API_TOKEN": "your_api_token"
      }
    }
  }
}

Tools

jira_list_fields

Lists Jira fields (including customfield_*) via /rest/api/3/field.

jira_search_issues_jql

Search issues using JQL via /rest/api/3/search.

jira_create_issue

Create an issue via /rest/api/3/issue (provide fields including project + issuetype + summary, plus any customfield_*).

jira_search_users

Searches users and returns accountId candidates via /rest/api/3/user/search.

jira_resolve_user_account_id

Resolves a best-match user and returns the chosen accountId (useful for user picker custom fields).

jira_get_issue

Fetches an issue via /rest/api/3/issue/{key}.

jira_update_issue_fields

Updates issue fields via /rest/api/3/issue/{key} PUT.

• Supports customfield_* updates
• Supports sending raw ADF JSON for ADF-backed fields (e.g., description and some multi-line custom fields)
• Includes optional flags:
  • notifyUsers
  • overrideScreenSecurity
  • overrideEditableFlag
  • validateAdf (default true)

jira_add_comment

Add a comment via /rest/api/3/issue/{key}/comment (wrapper accepts plain text or ADF doc).

jira_get_transitions

List available transitions via /rest/api/3/issue/{key}/transitions.

jira_transition_issue

Apply a transition via /rest/api/3/issue/{key}/transitions (use jira_get_transitions to find transitionId).

jira_bulk_create_issues

Bulk create issues via POST /rest/api/3/issue/bulk.

Input is an array of issueUpdates entries, each with:

• fields: issue creation fields (must include project, issuetype, summary, etc.)
• update (optional): Jira update object

jira_bulk_get_editable_fields

Get the bulk-editable field IDs for a set of issues via GET /rest/api/3/bulk/issues/fields.

Use the returned field IDs as selectedActions for jira_bulk_edit_issues.

jira_bulk_edit_issues

Bulk edit issues via POST /rest/api/3/bulk/issues/fields.

Requires:

• selectedIssueIdsOrKeys: issue IDs or keys to edit
• selectedActions: field IDs to edit (use jira_bulk_get_editable_fields)
• editedFieldsInput: object containing values to apply (must align with selectedActions)

Practical examples

Set a user picker field (e.g. customfield_10246)

1. Resolve accountId:

• call jira_resolve_user_account_id with query="[email protected]"

2. Update the issue:

• call jira_update_issue_fields with:
  • issueKey="WOR-2367"
  • fields={ "customfield_10246": { "accountId": "<accountId>" } }

Set an ADF field

If your local record already stores ADF JSON, send it directly as the field value (must include type:"doc", version, and content).

Notes / caveats

• Jira Cloud frequently does not expose email addresses in API responses depending on org privacy settings. This wrapper supports resolving by display name as a fallback.
• For many “people picker” fields, Jira Cloud expects accountId (not email).
