Developer-friendly & type-safe Typescript SDK specifically catered to leverage *opal-mcp* API.
Connect Opal MCP to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Developer-friendly & type-safe Typescript SDK specifically catered to leverage opal-mcp API. The opal mcp mcp server is what makes that connection.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Read-only — For applications that only need to view resourcesFull-access — For applications that need to create or modify resourcesInstallation — The Installation tool exposed by this serverPNPM — The PNPM tool exposed by this serverYarn — The Yarn tool exposed by this serverConfiguration is passed through the environment: API_KEY, SERVER_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Opal MCP's toolset — Read-only, Full-access, Installation and 2 more — is a fair guide to whether it matches your workflow. It is maintained by opalsecurity; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
