Registries are searchable catalogs of MCP servers that the find (and search) command queries when you look up a server by keyword. Each registry exposes an HTTP endpoint that add-mcp calls at search time, and the results from all enabled registries are merged, deduplicated, and ranked before being presented to you. add-mcp ships with two built-in registries and also lets you plug in any number of custom ones.

​
How the find command uses registries

When you run npx add-mcp find <keyword>, add-mcp sends a GET request to every enabled registry URL with your keyword as the search query parameter. Results across all registries are merged and deduplicated by name@version. The combined list is then ranked—exact name matches score highest, followed by title and description matches—and presented as an interactive selection list. 
# Search for a server by keyword
npx add-mcp find vercel

# Browse all available servers (no keyword)
npx add-mcp find

# Install the top result non-interactively
npx add-mcp find neon -a claude-code -g -y
search is an alias for find and behaves identically.

​
One-time registry setup

The very first time you run find or search, add-mcp prompts you to choose which built-in registries to enable. Your selection is written to ~/.config/add-mcp/config.json (or $XDG_CONFIG_HOME/add-mcp/config.json if that environment variable is set) and reused on every subsequent search—no prompt is shown again.
If you run find with -y before completing this one-time setup, the CLI exits early with a message asking you to re-run without --yes so the registry selection prompt can proceed.

​
Config file format

Registry selections are stored under the findRegistries key: 
{
  "version": 1,
  "findRegistries": [
    {
      "url": "https://mcp.agent-tooling.dev/api/v1/servers",
      "label": "add-mcp curated registry"
    },
    {
      "url": "https://registry.modelcontextprotocol.io/v0.1/servers",
      "label": "Official Anthropic registry"
    }
  ]
}
To reset and re-trigger the interactive selection prompt, remove the findRegistries key from the file (or delete the file entirely). The next find run will prompt you to choose again.

Built-in registries

add-mcp curated registry

URL: https://mcp.agent-tooling.dev/api/v1/serversA hand-curated list of first-party, verified MCP servers from popular developer tools and SaaS services. Designed to surface high-quality, officially maintained servers rather than a long tail of unmaintained or third-party entries. This registry is backed by registry.json in the add-mcp GitHub repository.

Official Anthropic registry

URL: https://registry.modelcontextprotocol.io/v0.1/serversThe community-driven MCP server registry maintained by Anthropic. Contains the broadest catalog of MCP servers across the ecosystem, including community-contributed and third-party servers.

​
Transport selection from find results

Transport for find/search results is inferred automatically from the registry metadata—you do not need to pass --transport.
  • HTTP preferred: when a server advertises a streamable-http remote, add-mcp selects it by default.
  • SSE fallback: if only an SSE remote is available, add-mcp falls back to SSE transport automatically.
  • Both remote and stdio available: in interactive mode you are asked to choose between the remote URL and the local stdio package (remote is the suggested default). With -y, the remote option is always selected automatically.

​
Example servers in the curated registry
