JustFill PDF Form Automation missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 14 min ago.

Claude Code Claude Desktop Codex Cursor VS Code

run in your terminal

claude mcp add justfill-pdf-forms --transport http https://api.justfill.app/api/mcp

This one needs environment variables set before it will start: JUSTFILL_API_KEY (API key from justfill.app -> Account -> API Keys. Optional: `justfill-mcp login` stores one via the browser instead.). The author declared them in the registry entry; get the values from the project itself.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

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: 100.0% 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 91 of 91 checks got a reply (100.0%), average response time 243 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 sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to JustFill PDF Form Automation?

No API key is involved. JustFill PDF Form Automation answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is JustFill PDF Form Automation?

It answers our handshake in 243 ms on average, which is faster than 53% 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 262 times in the last week. Week over week that is +15%. 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.
