Read Builder Prime projects and meetings, and create or update them from chat.
The publisher's own server: Ably MCP by usefulapi
Hosted MCP server for Builder Prime: read projects, meetings, employees and meeting types, and create or update projects and meetings from chat.
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%2Fbuilder-prime/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.

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 Builder Prime credentials.

Verification limitation: real-account authentication, reads and writes have not been tested. Published example-tenant probes return a generic JSON 400 for missing and synthetic keys. This release passed mock integration and hosted Worker tests; real-tenant verification remains outstanding.
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 builderprime_upgrade (it returns a Stripe Checkout link). Cancel any time with builderprime_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running builderprime_upgrade before then undoes the cancel. Or write to [email protected].

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.
