A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Scope: getting [sooperset/mcp-atlassian](https://github.com/sooperset/mcp-atlassian) — the MCP server that gives an agent Jira/Confluence tools — connected, hardened, and debugged, including air-gapped. This is the setup/ops layer: the knowledge that is invisible at tool-call time.
Hard boundary — what this skill does NOT do. Once the server is connected, it self-documents its full tool set at runtime (72 at v0.21.1; v0.22.0/v0.23.0 added more — the live list is the count) (names, params, schemas) over the MCP protocol — so using the tools (jira_search, jira_create_issue, jira_transition_issue, …) needs no skill; just call them. For exhaustive tool/JQL/CQL docs, the project publishes an LLM-readable `https://mcp-atlassian.soomiles.com/llms-full.txt` — fetch it on demand instead of duplicating it here. Sibling skills: `jira-cli` (the jira CLI as an alternative execution path) and `jira-best-practices` (how to use Jira well — hierarchy, lean config). This skill is only the install/auth/hardening/air-gap/troubleshooting that those don't cover and the live MCP can't surface.
Self-hosted Data Center is the default here. Where Cloud differs, it's flagged.
Claude's base instinct is the Cloud pattern — and it fails on Data Center.
| Deployment | Required env vars |
|---|---|
| Data Center / Server | JIRA_URL + `JIRA_PERSONAL_TOKEN` (a Personal Access Token). No username. |
| Cloud | JIRA_URL + JIRA_USERNAME (email) + JIRA_API_TOKEN |
DC PATs: created at profile → Personal Access Tokens; max 10 per user; set an expiry. Full auth matrix (OAuth 2.0, BYOT, multi-cloud) + the complete env-var catalog: `references/auth-config.md`.
mcp-atlassian runs a separate client per product, each gated on its own *_URL + auth. *Supply only `JIRA_ and you get only jira_` tools — Jira's vars do not carry over to Confluence (and vice-versa), and the missing product's tools just don't appear, with no error*. To add Confluence:
| Cloud | Data Center | |
|---|---|---|
| URL | CONFLUENCE_URL=https://<site>.atlassian.net/wiki — note the `/wiki` (Jira is the bare domain) | its own host / context path, e.g. https://confluence.internal.company.com |
| Auth | CONFLUENCE_USERNAME + CONFLUENCE_API_TOKEN — the same email + token as Jira (Cloud API tokens are account-scoped; reuse the Jira values) | CONFLUENCE_PERSONAL_TOKEN (a PAT, like Jira) |
TOOLSETS=all/default already covers both products, so missing tools mean missing creds, not a toolset problem. After any env change, reconnect (/mcp → reconnect, or restart — env is read only at spawn) and verify with claude mcp list + the tool count. Symptom row: references/troubleshooting.md.
uvx is the runner for a connected host; Docker/image is the path for production and air-gap. Add it to Claude Code with claude mcp add (the upstream docs only show Claude-Desktop/Cursor JSON):
# Data Center, Jira only (add CONFLUENCE_URL + CONFLUENCE_PERSONAL_TOKEN for Confluence too):
claude mcp add mcp-atlassian \
-e JIRA_URL=https://jira.internal.company.com \
-e JIRA_PERSONAL_TOKEN=<pat> \
-- uvx mcp-atlassian
# Cloud, BOTH products — same email + token; Confluence URL ends /wiki:
claude mcp add mcp-atlassian \
-e JIRA_URL=https://your-co.atlassian.net -e CONFLUENCE_URL=https://your-co.atlassian.net/wiki \
-e [email protected] -e [email protected] \
-e JIRA_API_TOKEN=<token> -e CONFLUENCE_API_TOKEN=<token> \
-- uvx mcp-atlassianOther install methods (pip, uv, source) exist but pull from PyPI — see references/air-gapped.md for why that matters offline.
Self-hosted Jira usually presents an internal-CA or self-signed cert. mcp-atlassian trusts the OS trust store by default (via truststore), so a CA already in the host's Windows/macOS/Linux store works with no config. Two fixes when it doesn't (e.g. inside a container, which only has the stock bundle):
update-ca-certificates on Linux), or point at a bundle with REQUESTS_CA_BUNDLE=/path/ca.pem / SSL_CERT_FILE=/path/ca.pem.-v /etc/pki/internal-ca.crt:/usr/local/share/ca-certificates/internal-ca.crt:ro (Alpine image: the cert dir is /usr/local/share/ca-certificates/; the bundled python:3.13-alpine won't have the internal CA otherwise).JIRA_CLIENT_CERT=/path/cert.pem + JIRA_CLIENT_KEY=/path/key.pem.JIRA_SSL_VERIFY=false (and CONFLUENCE_SSL_VERIFY=false). Disables cert checking for that service. Acceptable on a trusted internal network; flag it as a deliberate downgrade.certifi CA instead of the OS store: MCP_ATLASSIAN_USE_SYSTEM_TRUSTSTORE=false.The container-CA step is the most common air-gap surprise — a self-contained image still doesn't trust the internal CA. Full detail in references/air-gapped.md.
A full git mirror of the repo is NOT enough — the dependency wheels live on PyPI, not in git. If the environment can serve container images, the clean path is to mirror the prebuilt image by digest (it bakes Python + all deps in — no PyPI, no git needed at install or run):
# 1. resolve + mirror the prebuilt image, pinned by digest (supply-chain hygiene)
skopeo copy --all \
docker://ghcr.io/sooperset/mcp-atlassian:v0.23.1 \
docker://harbor.internal/mirror/mcp-atlassian:v0.23.1
# 2. connect (stdio needs -i); mount the internal CA so TLS verifies
claude mcp add mcp-atlassian \
-e JIRA_URL=https://jira.internal.company.com \
-e JIRA_PERSONAL_TOKEN=<pat> \
-- docker run -i --rm -e JIRA_URL -e JIRA_PERSONAL_TOKEN \
-v /etc/pki/internal-ca.crt:/usr/local/share/ca-certificates/internal-ca.crt:ro \
harbor.internal/mirror/mcp-atlassian@sha256:<digest>Critical nuance: *mirror the prebuilt image (no PyPI). Building the image from a git mirror still needs a PyPI index for `uv sync` plus the two base images mirrored. The 3-artifact-type breakdown, the build-from-source path, and digest-pinning are in `references/air-gapped.md`*.
The server exposes 72 write-capable tools; scope it deliberately.
TOOLSETS=default ≈ 23 core tools; add extras like default,jira_agile. `ENABLED_TOOLS` allow-lists individual tools; the two intersect.The upstream warning says "In v0.22.0, the default will change to 6 core toolsets only" — that text is still emitted at v0.23.1, two minors later, and the code beneath it still returns everything. In src/mcp_atlassian/utils/toolsets.py at tag v0.23.1, get_enabled_toolsets() does if not toolsets_str: ... return set(ALL_TOOLSETS.keys()). An unset TOOLSETS enables all 24 toolsets. Setting TOOLSETS=all is harmless and future-proof, but it is not required to keep today's behaviour, and an agent that "lost tools on upgrade" did not lose them this way. The upstream docs contradict themselves here — a stale warning box next to prose saying all toolsets are enabled when unset — so read the source, not either one.
name is unknown you get zero tools (fail-closed). A typo in TOOLSETS disables the server quietly.
streamable-http request fell back to the operator's global credentials; now such requests get 401, with the old behaviour opt-in via ALLOW_GLOBAL_CRED_FALLBACK (default off). stdio deployments were never exposed. Do not set that variable to silence a post-upgrade 401 — it restores the vulnerability. v0.22.0 also confines attachment/content_file paths to the server's working directory (use the new content_base64 input instead of absolute paths). See references/hardening.md.--transport sse was unauthenticated up to and including v0.23.0 —upgrade to v0.23.1. GHSA-5j8j-256g-vvp5, CRITICAL, published 2026-08-19, affected range `<= 0.23.0`: `UserTokenMiddleware` never matched the SSE paths, so `/sse` and `/messages` executed tools as the operator with no per-request authentication**. This is a second, separate transport hole from the v0.22.0 streamable-http one above — closing that one did not close this. v0.23.1 makes the SSE endpoints enforce the same per-request auth as streamable-http. If you run SSE on any build at or below v0.23.0, treat it as remotely exploitable, not as a hardening nicety. v0.23.1 also pins atlassian-python-api to >=4.0.0,<5.0.0, because the 5.0 line removed get_page_by_id / create_page / update_page and broke fresh installs.
