Connecting Grimoire to Claude, now one click

Grimoire MCP is now upgraded! Importantly, this means setup is just a few clicks away rather than needing any additional installs or config file editing.

1. Claude.ai → Settings → Connectors → Add custom connector
2. Paste https://api.ttrpg.bot/mcp
3. Sign in with your Grimoire account, pick which campaign Claude can see, click Approve

Done. No Node.js. No terminal. No API tokens to copy out of a settings page. Ask Claude “who’s the blacksmith in Millbrook, and who hates them?” and the answer comes from your campaign in real time.

What changed

Grimoire MCP moved to the current MCP spec: streamable HTTP transport, OAuth 2.1 with PKCE, JWT access tokens.

Related change: access is scoped to one campaign per connector. When you approve, you pick which campaign Claude sees, and only that one campaign comes through this connector. Add a second connector if you want to expose another campaign. The boundary is enforced server-side to prevent cross-contamination of your lore and rulesets. Name your connector something like “Grimoire - (Campaign Name)” to identify each, and toggle them on and off as needed in your chats.

If you want the deeper architecture story for what Claude actually sees, the secret sauce post walks through the five-layer context model that makes Grimoire MCP different from generic AI tools and other TTRPG AI services.

Free-tier opportunity

Custom connectors work on Claude.ai’s free tier. Free accounts are capped at one custom connector. Grimoire for Gamemasters doesn’t put MCP functionality behind the paid tiers. You don’t need to pay Anthropic or TTRPG.bot to try this out.

Why this matters

The old setup was roughly eight steps (install Node, install an npm package, find a config file in a hidden directory, edit JSON, generate a token, copy the token, paste the token, restart Claude) before you got to ask a single question. The new one is three clicks and a sign-in. Certifiably 100x easier and less intimidating.

Setup takes about a minute now.

This also unblocks our next step: getting Grimoire into Anthropic’s Connectors Directory, the curated list of MCP integrations Claude.ai users browse to find tools like this one. Submission is going out shortly. More when there’s more to say.

If you’ve been on the fence about Grimoire MCP because it sounded like a developer thing, it isn’t anymore. Try it for free.
