Is Atlassian MCP server safe?
What Atlassian MCP server does
The Atlassian MCP Server is a cloud-hosted bridge that gives AI tools access to Jira, Confluence, Jira Service Management, Bitbucket, Compass, Loom and other Atlassian Cloud data. It is published in the atlassian/atlassian-mcp-server repository and connects at mcp.atlassian.com. It authenticates with OAuth 2.1 or API tokens and follows the user's existing permissions; tools are organized into read, write, search, delete and manage permission groups. Before installing, have an admin review which permission groups are enabled; delete_jira and manage_jira are disabled by default and can stay off unless you need them.
- Node.js filesystem read
- Node.js network egress
- MCP tool surface detected
What to do: Nothing here argues against installing it. Grant the capabilities it lists only if you expect the tool to need them.
Atlassian MCP server is an MCP server analyzed by SkillTotal's deterministic static scanner. The scan found no malicious indicators. It can: filesystem read, mcp tools detected and network egress — capabilities are what the code can do, not a verdict on intent. Risk score 0/100 (low).

Behavioral traits
How this component maps to the CSA agentic threat model. Descriptive — it never affects the risk score.
Findings (3)
The component reads files from disk.
const content = await fs.readFile(filePath, "utf8");
const content = await fs.readFile(skillPath, "utf8");
raw = await fs.readFile(filePath, "utf8");
Why it matters: Usually legitimate, but worth confirming it can't be steered into reading sensitive files.
Fix: Confirm which files are read and that paths cannot be influenced by untrusted input to reach sensitive locations.
The component makes outbound network requests.
import { validateHeaderName, validateHeaderValue } from "node:http";Why it matters: Usually legitimate, but confirm the destinations are expected and no sensitive data leaves.
Fix: Confirm the destination hosts are expected and that no sensitive data is sent off-host.
An MCP tool surface (manifest or tool definitions) was found.
"mcpServers": {"mcpServers": {"mcpServers": {Why it matters: Just context — review which tools it offers and their permissions.
Fix: Review the declared MCP tools and their permissions.
Maintain Atlassian MCP server?
The free Claude Code plugin scans each npm, PyPI or MCP package with this report's open-source engine before the install command runs. It runs on your machine and needs no account.
