Compatibility Matrix

Runtime

Component	Requirement
Node.js	>=22 (Node 20 is not supported)
Transport	MCP over stdio
Products	Jira / Confluence / Bitbucket Data Center (self-hosted); Atlassian Cloud is out of scope

Product version baseline

These versions are the generation and test baseline, not a startup allowlist. The server starts against other versions with a warning; actual API compatibility is determined by the target instance.

Product	Baseline versions	Pinned E2E image
Jira	DC 10.3 / 11.3	atlassian/jira-software:11.3.5
Confluence	DC 9.2 / 10.2	atlassian/confluence:10.2.11
Bitbucket	DC 9.4 / 10.2 / 10.4	atlassian/bitbucket:10.4.1

OpenAPI generation is pinned to official specs: Jira DC 11.3.8 (v11003), Confluence DC 10.2.14 (v10214), Bitbucket DC 10.4 (v1004) — see rule/api-inventory-official.md.

API scope

In scope for v1:

• Jira DC platform API (/rest/api/2/**)
• Jira Software Agile API (/rest/agile/**)
• Confluence DC API (/rest/api/**)
• Bitbucket DC API (all endpoints in the official reference)

Out of scope for v1:

• Jira Service Management, Assets, and Marketplace app APIs
• Atlassian Cloud APIs
• Global/system administration (cluster, indexing, migration, upgrade, licensing, global schemes, security bootstrap) — permanently excluded from the registry

CI matrix (development)

The project itself is tested on Node 22 + 24 across Ubuntu and Windows, plus a Docker build job. This concerns contributors, not deployments; see docs/en/test-strategy.md.
