Run read-only GraphQL queries and list documents and media assets in Caisy.
The publisher's own server: Ably MCP by usefulapi
Caisy MCP by usefulapi's hosted MCP server (caisy.usefulapi.io), published by usefulapi.io; no sign-in required; Streamable HTTP; 4 tools.
No AI overview yet: these facts come from the registry entry and the server itself.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fcaisy/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Use your Caisy account from Claude, Cursor, or any MCP client. Reads blueprints, documents and media assets of one Caisy project through read-only GraphQL queries. Hosted, no local install: connect with your own credentials.

https://caisy.usefulapi.io/mcp.claude mcp add --transport http caisy https://caisy.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Caisy credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/caisy/
On first connect you provide your Caisy project ID (the UUID in your GraphQL endpoint URL) and your Caisy API key (Settings → Development → API Keys). The server validates it and stores it per user. No keys go in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with caisy_upgrade (it returns a Stripe Checkout link). Cancel any time with caisy_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running caisy_upgrade before then undoes the cancel. Or write to [email protected].

Run a read-only GraphQL query
Run one read-only GraphQL query against this project's Caisy external API. Use it for any field, filter (where), sort, nested connection or localized value. Mutations and subscriptions are refused. Caisy: POST https://cloud.caisy.io/api/e/v4/<projectId>/graphql with header x-caisy-apikey.
queryrequiredvariablesList the project's read queries
List the top-level read fields of this project's Caisy schema: one all<Blueprint> list query per non-unique blueprint, one single-entry query per unique blueprint, and the asset query. Call it first to learn the blueprint API ids.
Takes no parameters.
List documents of a blueprint
List document ids of one blueprint with Relay pagination (all<Blueprint>(first, after)). Returns ids only: call caisy_run_query for the fields you need. Unique blueprints have no list query: use caisy_run_query with the blueprint's single-entry field.
afterfirstblueprintrequiredList media assets
List media assets (title and source URL) of this project, with Relay pagination. Use the cursor from pageInfo.endCursor to read further.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
