What kind of RPG data is included in this MCP?

It provides access to the Open5e database, which includes monsters, spells, classes, species, feats, equipment, and magic items for 5th Edition.

Which AI clients can I use with this?

You can use this MCP with any compatible client, including Claude, Cursor, and Windsurf.

Do I need to provide an API key?

Depending on your specific instance, you may need to enter an Open5e API key, though many setups use a placeholder.

Can I filter monster searches?

Yes, the list_creatures capability allows you to filter monsters by type, size, and challenge rating.

Is this for specific 5e versions?

This MCP is designed specifically for 5th Edition tabletop RPG data via the Open5e resource.

How can I find a monster with a specific Challenge Rating?

Use the list_creatures capability and provide the cr parameter (e.g., '1', '1/4', or '20'). You can also combine this with the type parameter to find, for example, all CR 5 Dragons.

Can I search for spells available only to a specific class?

Yes! Use the list_spells capability and set the class parameter to your desired class, such as 'Wizard' or 'Cleric'. You can further filter by level to narrow down the results.

What is the best way to find a specific rule or condition?

For status effects, use list_conditions. For general rules or supplemental text, use list_sections. If you aren't sure where it is, use search_open5e for a global search across all categories.

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put Open5e to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Open5e works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Open5e to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Open5e, so you can see the experience inside your AI.

It does not authenticate your account with Open5e. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
