Common questions
Is Excession Labs: site search and security test requests safe?
It passed 5 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 2 days ago, and the latest version (1.2.0) reached the registry yesterday.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.
What can I use instead?
In the same category: Robin: AI-Powered Dark Web OSINT, HOL Guard, SonarQube MCP Server

Excession Labs MCP servers
Three hosted, remote MCP servers (Streamable HTTP) run by Excession Labs, a security lab. They are listed in the official MCP Registry. This repository documents them: endpoints, tools, input schemas and examples. The servers are hosted; you connect to the URLs below and install nothing.
| Server (registry name) | URL | Tools |
|---|---|---|
com.penetrationtestservices/site | https://penetrationtestservices.com/mcp | check_security_headers, request_pentest, search_site, get_page, how_to_contact |
com.pentestcompare/site | https://pentestcompare.com/mcp | list_providers, get_provider, search_site, get_page, how_to_contact |
com.airedteamingservices/site | https://airedteamingservices.com/mcp | request_pentest (AI application assessments), search_site, get_page, how_to_contact |
Full tool definitions: servers/ .tools.json. Server cards: servers/ .server-card.json. Registry entries: servers/ .server.json.
Auth and limits
Reading needs no credential: 120 requests a minute per IP. An optional anonymous agent key from POST https:// /agent/auth raises that to 600 a minute (details in https:// /auth.md).
request_pentest needs the key. It sends a test request to Excession Labs for a person who asked for one. person_consent and authorized must be true. Excession Labs replies to the person by email, and testing starts only after a written scope and written authorization. Limits: 5 requests a day per key and 3 a day per email address. Never send passwords, keys or customer data.
Every other tool is read-only.
