DataLayer MCP — stdio package. The recommended way to use DataLayer with AI agents is now the hosted remote MCP server at https://api.datalayer.sh/mcp (Streamable HTTP + OAuth 2.1). This package is maintained as a fallback for environments. The mcp mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 1 defined tool rather than through you.
OAuth metadata (RFC 9728): https://api.datalayer.sh/.well-known/oauth-protected-resource
DataLayer is a B2B data enrichment API. This MCP server lets AI agents call it directly — no code, no HTTP requests, just natural language.
Everything the assistant can do here goes through one of these:
Cursor — The Cursor tool exposed by this serverYou will need 2 environment variables: DATALAYER_API_KEY, DATALAYER_API_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
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. MCP's toolset — Cursor — is a fair guide to whether it matches your workflow. It is maintained by datalayer-sh; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
