Agent: "What's the status of PROJ-42? Add a comment with the progress update."

a2atlassian → get issue, add comment, transition to In Progress

Agent: "Done — PROJ-42 updated and moved to In Progress."
Why a2atlassian?
Existing Atlassian MCP servers (Rovo, sooperset) require Docker, .env files, and mcp-remote bridges. They dump 72 tools into agent context and have known quirks that silently fail. a2atlassian fixes all of that:
- No Docker —
pip install a2atlassianand you're done - Pre-configured connections — define projects in
.mcp.jsonwith--register, agent works immediately - Read-only by default — write access is opt-in per connection
- Connection scoping —
--scopelimits which projects an agent can see - Compact output — TSV for lists (30-60% fewer tokens), JSON for single entities
- Dynamic tool loading — MCP clients that support deferred tools (e.g., Claude Code) load tools on demand, keeping context lean
- Error enrichment — bad field names get suggestions, JQL typos get corrections, quirks get auto-fixed
- Secrets stay in env —
${ATLASSIAN_TOKEN}in configs, expanded only at runtime
Quick Start
# Recommended — installs globally as a CLI tool
uv tool install a2atlassian
# Or with pip
pip install a2atlassian
As an MCP Server (recommended)
Claude Code (with pre-configured connection):
claude mcp add -s user a2atlassian -- uvx --from a2atlassian a2atlassian-mcp \
--register myproject https://mysite.atlassian.net user@company.com '${ATLASSIAN_TOKEN}'
Claude Code (minimal — agent calls login on demand):
claude mcp add -s user a2atlassian -- uvx --from a2atlassian a2atlassian-mcp
Claude Desktop / Cursor / any MCP client (.mcp.json):
{
"mcpServers": {
"a2atlassian": {
"command": "uvx",
"args": [
"--from", "a2atlassian", "a2atlassian-mcp",
"--register", "myproject", "https://mysite.atlassian.net",
"user@company.com", "${ATLASSIAN_TOKEN}"
],
"env": {
"ATLASSIAN_TOKEN": "your-api-token-here"
}
}
}
}
Multiple projects:
{
"args": [
"--from", "a2atlassian", "a2atlassian-mcp",
"--register", "myproject", "https://mysite.atlassian.net", "user@a.com", "${TOKEN_A}",
"--register", "personal", "https://personal.atlassian.net", "user@b.com", "${TOKEN_B}"
]
}
Scoped connections (limit agent to specific saved projects):
{
"args": ["--from", "a2atlassian", "a2atlassian-mcp", "--scope", "myproject"]
}
--register creates ephemeral in-memory connections (process lifetime, no files written). --scope filters which saved connections are visible. Both limit blast radius.
As a CLI
# Save a connection (validates by calling /myself)
a2atlassian login -p myproject \
--url https://mysite.atlassian.net \
--email user@company.com \
--token "$ATLASSIAN_TOKEN"
# Enable writes
a2atlassian login -p myproject \
--url https://mysite.atlassian.net \
--email user@company.com \
--token "$ATLASSIAN_TOKEN" \
--no-read-only
# List / remove connections
a2atlassian connections
a2atlassian logout -p myproject
MCP Tools
Connection Management
| Tool | Description |
|---|---|
login | Save a connection — validates by calling /myself first |
logout | Remove a saved connection |
list_connections | List connections (no secrets exposed) |
Jira — Read
| Tool | Description |
|---|---|
jira_get_issue | Get issue by key — full fields, status, assignee |
jira_search | Search by JQL with pagination — compact TSV output by default |
jira_get_comments | Get all comments for an issue |
jira_get_transitions | Discover available status transitions |
Jira — Write (requires read-write connection)
| Tool | Description |
|---|---|
jira_add_comment | Add comment (wiki markup, API v2) |
jira_edit_comment | Update existing comment |
jira_transition_issue | Move issue to new status |
Output Formats
All tools accept a format parameter:
| Format | Default for | Description |
|---|---|---|
toon | Lists (search, comments) | TSV with header — shape once, data many. 30-60% fewer tokens than JSON |
json | Single entities (get_issue) | Standard JSON with metadata envelope |
List responses use a compact TSV-style format (header row + tab-separated values) inspired by TOON. This is the same approach a2db uses — column names appear once, then just values. For a 50-issue search result, this typically saves 40-60% of tokens compared to JSON.
TSV example (search results):
# search (23 results, 50ms, truncated: False)
key summary assignee status
PROJ-142 Fix auth timeout Alice Smith In Progress
PROJ-141 Add search filters Bob Jones To Do
JSON example (single issue):
{
"data": {"key": "PROJ-142", "fields": {"summary": "Fix auth timeout", ...}},
"count": 1,
"truncated": false,
"time_ms": 85
}
Error Enrichment
When something fails, a2atlassian tells the agent what to do:
Field 'asignee' does not exist
Did you mean: assignee?
Connection 'myproject' is read-only.
Run: a2atlassian login -p myproject --read-only false
Quirks handled automatically:
- Assignee requires display name (not
712020:account IDs) — auto-detected with hint - Parent field must be plain string —
{"key": "PROJ-14"}normalized to"PROJ-14"silently - Issue type conversion not supported via API — clear Jira UI instructions provided
Security
Read-Only by Default
Every connection starts read-only. Write tools check the connection flag before executing:
Connection 'myproject' is read-only.
Re-run 'a2atlassian login -p myproject --read-only false' to enable writes.
The human operator controls write access — not the agent.
Credential Storage
Connections saved via login go to ~/.config/a2atlassian/connections/ as TOML files:
- File permissions:
0600(owner read/write only) ${ATLASSIAN_TOKEN}syntax — env var references stored literally, expanded at runtime- No secrets in output —
list_connectionsshows project name, URL, and mode — never tokens - Ephemeral mode —
--registerkeeps credentials in memory only, never written to disk
Connection Scoping
Use --scope to limit which saved connections a specific MCP instance can access:
# Project config — only myproject visible, even if other connections are saved
uvx --from a2atlassian a2atlassian-mcp --scope myproject
Project-level MCP configs (.claude/mcp.json) override global configs — each repo sees only its own connections.
Rate Limiting
Built-in retry with exponential backoff for Atlassian's rate limits (429) and transient server errors (500). Two retries at 1s and 3s intervals before surfacing the error.

Roadmap
Phase 1 (current): Jira core — get/search issues, comments (CRUD), transitions. The secondary critical path.
Phase 2: Full Jira surface — sprints, boards, links, projects, fields, worklogs, attachments, watchers.
Phase 3: Confluence — pages, comments, attachments, labels, search.
