CLAUDE.md

mcp-atlassian CLAUDE.md is an instructions file for Claude Code from samwang0723/mcp-atlassian. It costs 783 tokens per session, scanned A, original, MIT.

Development instructions for an Atlassian integration server. Atlassian provides tools such as Jira for issue tracking and Confluence for shared documentation; the server connects agents to them through MCP.

In plain words
What is it for?
Use it when developing or maintaining this Jira and Confluence MCP server, including its services, tools, configuration, and build process.
Why use it?
It gives contributors the commands and code layout needed to build, run, format, lint, and inspect the integration. The input says no real test suite is configured.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-atlassian CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Development Commands

Building and Development

  • npm run build - Compile TypeScript to JavaScript in dist/
  • npm run dev - Run in development mode with ts-node
  • npm start - Run the production build from dist/

Code Quality

  • npm run lint - Run ESLint on TypeScript files
  • npm run format - Format code with Prettier

Testing

  • No test suite is currently configured (package.json shows placeholder test command)

Architecture Overview

This is an MCP (Model Context Protocol) server that provides integrations with Atlassian tools (Jira and Confluence). The codebase follows a modular service-oriented architecture:

Core Structure

  • src/index.ts - Main entry point that initializes the MCP server and conditionally registers tools based on configuration
  • src/services/ - Core API service classes for Jira and Confluence that wrap the underlying client libraries
  • src/tools/ - Individual MCP tool implementations, each exported as a registration function
  • src/config/env.ts - Centralized environment configuration with validation
  • src/utils/tool-filter.ts - Tool filtering logic for read-only mode and selective tool enabling

Key Architecture Patterns

Service Layer

The JiraService and ConfluenceService classes encapsulate API interactions:

  • JiraService uses ts-jira-client library
  • ConfluenceService uses confluence.js library
  • Both support multiple authentication methods (basic auth, OAuth, PAT)
  • SSL verification is configurable per service
Tool Registration Pattern

Tools are implemented as individual modules that export registration functions:

  • Each tool registers itself with the MCP server instance
  • Tool availability is controlled by configuration (enabled tools list, read-only mode)
  • Tools are categorized as READ_TOOLS or WRITE_TOOLS for access control
Configuration System

Environment-based configuration with:

  • Support for separate Jira/Confluence URLs or unified Atlassian host
  • Multiple authentication methods with automatic fallbacks
  • Tool filtering and read-only mode capabilities
  • SSL verification controls per service

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
