What it does
Server Side is an agent skill from transilienceai/communitytools. Server-side vulnerability testing - SSRF, HTTP Request Smuggling, Path Traversal, File Upload, Insecure Deserialization, and Host Header injection.
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. The skill folder holds 58 other files (for example `reference/INDEX.md`, `reference/file-upload-resources.md` and `reference/http-host-header-resources.md`).
It sits in Security, covering Backend development, Web application vulnerabilities and File uploads and storage. The repository describes itself as: Open-source Claude Code skills, agents, and slash commands for AI-powered penetration testing, bug bounty hunting, and security research. The licence is MIT.
When your agent uses it
- Tasks that involve Backend development
- Tasks that involve Web application vulnerabilities
- Tasks that involve File uploads and storage
Example prompts
- “/server-side”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Identify server-side processing points
- Test for vulnerability class indicators
- Bypass protections (WAF, allowlists, encoding filters)
- Demonstrate impact (file read, RCE, internal access)
- Capture evidence with PoC
What it can do on your machine
Read from SKILL.md and the folder at commit 95fdc12. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Python, from the files we listed), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Server Side loads about 484 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 159 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Test for server-side vulnerabilities that allow unauthorized access, RCE, or data exfiltration.
Techniques
| Type | Key Vectors |

| Deserialization | Java, PHP, Python, .NET gadget chains |
| Host Header | Password reset poisoning, cache poisoning, routing-based SSRF |
| CUPS / cups-browsed | CVE-2024-47076/47175/47176/47177 — UDP browse → IPP injection → PPD injection → foomatic-rip RCE (see skills/infrastructure/reference/scenarios/network-recon/cups-browsed-rce.md) |
Workflow
- Identify server-side processing points
