JustFill PDF Form Automation — questions
Answers built from our own checks of this server.
Why is there no tool list for JustFill PDF Form Automation?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 98.9% of checks in the last 24 hours got a reply.
Is JustFill PDF Form Automation working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 180 ms. The bar chart above shows every period we have measured.
How do I connect JustFill PDF Form Automation?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You will need your own key or an OAuth login: it refuses anonymous clients.
Does JustFill PDF Form Automation need an API key?
Yes. Every time we knock, JustFill PDF Form Automation answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is JustFill PDF Form Automation?
It answers our handshake in 180 ms on average, which is faster than 67% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use JustFill PDF Form Automation?
The pypi package justfill-mcp was installed 1 239 times in the last week. Week over week that is +416%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is JustFill PDF Form Automation open source?
Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
