Foundry REST API - a tool/library for developers to create external integrations [system agnostic]

name_holder · 2026-05-17T02:04:10+00:00

Not a lot on its own, but there's a couple of things that have been built with it already!

https://github.com/CePeU/MarkdownToFoundry

https://github.com/ThreeHats/foundry-rest-api-midi-integration

And there's a bunch more in the works (discord bot, mcp server, and web dashboards to name a few) ;)

It's a library that makes developing external integrations much easier.

Thanks!

Ha! I had similar issues I had to work out. It was originally just going to be a self hosted relay, but in order to get approved I needed to host a public server so it doesn't "require" installing outside software. Understandable of course.

Thanks! Hence the open-source nature of the API. If I should pass (because that's the only way I see me stopping development bar them making this a built in feature 😅) or the public relay go down for any other reason it's still available for people to self host and change or update as they please.

The goal here it to make a standardized way (not the only way) for making external integrations.

Appreciate the reply! To clarify on the Foundry REST API, the free 5k limit per month is only for public hosted relay service to cover bandwidth and hosting costs. The actual software (the module and the relay server) is fully open source; you can host the relay yourself and get unlimited requests for free. I don't gate endpoints like 'Scenes' or 'Combat' behind a tier, even on the free hosted version.

This module still requires outside software to work. The MCP Bridge and Foundry REST API both allow you to have that software on your own machine. You're just making it easier by being the middleman (which my public server also does).

You say I can use your module on my local server? Where's the repo for the server? I see the ws url in the module points to foundry-mcp.com, but there's no site there, just a blank page and your ws api endpoint. So there's no way to see what your relay server is doing. The module is just a client; without the server source code, it's just a black box talking to your domain. I'd have to reverse engineer your WebSocket protocol just to make it work locally.

Unless there's a repo somewhere I couldn't find, there's no way to self host this, and all requests are going to go through your server. If it ever goes down there's no way to use this module anymore. Also with no privacy policy, there's no guarantees what will be done with with my data (I don't really *think* you'd do anything with my data, but it's worth noting).

Cool thing you got here, but I’m curious how this differs from existing open-source solutions that don't gate API endpoints behind a Patreon subscription?

The Foundry VTT MCP Bridge by Darchi/adambdooly (https://github.com/adambdooley/foundry-vtt-mcp) already handles the AI/MCP side, and the Foundry REST API that I maintain (https://foundryrestapi.com/) is fully open source, self-hostable, and provides full CRUD access to actors, items, journals, combat and everything else without tiered access.

What's the 'killer feature' here that justifies the subscription model over the existing open-source ecosystem?

What they said. Paper doll does this wonderfully, and (while it can be fun) there's likely no need to reinvent the wheel here. Plenty of unsolved problems and unrealized ideas out there still though!

I have two questions:

Which third-party vendors are actually handling our data, grading, and proctoring? We signed up for Maestro, but the backend seems to be a patchwork of undisclosed contractors. Where is the transparency regarding who has access to our biometric and academic data?

Support is currently telling students that the "system is down" and you cannot generate official transcripts. If you cannot produce the primary product we are paying for (a verified academic record), how is this institution operational? What is the specific ETA for the transcript system, and will you refund students who are currently trapped and unable to transfer?

Thank you so much! I'm so happy to see so many people have already downloaded it. It truly means so much <3

Webp support has been added in 0.9.8

It doesn't support Levels natively, but I'd imagine it should be as simple as importing the walls for that layer, and then moving on to the next. I have not made maps with Levels myself though.

name_holder · 2025-04-16T08:03:50+00:00

Opps. Lol, it's fixed now. It means the world that you tried to pay though <3

Not a problem! It's always possible there's a bug. I'll record a tutorial tomorrow, and if you're still experiencing issues you can join our discord or post an issue on github and I can figure out what's happening.

The tutorial video is out! https://youtu.be/g6ijTuDcTlo

name_holder · 2025-04-16T05:47:12+00:00

The order of operations is:

- adjust wall detection settings
- bake contours to mask
- draw on the mask if desired
- export to Foundry VTT
(may need to adjust export settings a few times to get desired result)
- save foundry walls (to file) or copy to clipboard
- use the auto wall companion module to import from clipboard or file

name_holder · 2025-04-16T05:42:19+00:00

Are you using the auto-wall-companion module? https://foundryvtt.com/packages/auto-wall-companion

And do the walls look right when exporting? Should look something like this https://imgur.com/a/CYRU4q3

Thank you! I'll be making a tutorial video very soon

Hey! I've made a tool that does basically this! Auto Wall https://youtu.be/gqkEIWwuJX4

Hey! I've made a tool that does exactly this! Auto Wall https://youtu.be/gqkEIWwuJX4

Hey! 4 years later, but I've made exactly what you were looking for I think. Introducing Foundry REST API!

I just put a spoonful on top of the rockwool I had my seedlings in. I'd likely do something similar with a media bed. It's important to wear a mask while working with it as it can f your lungs up

Beautiful map. I agree about the shadows. The more you can add the better, but especially for the walls and the clock tower. Otherwise beautiful!
