hermes-atlas-mcp
MCP server exposing the Hermes Atlas ecosystem catalog — 100+ community-built tools, skills, plugins, memory providers, workspaces, and integrations for Nous Research's Hermes Agent — to any MCP-aware client (Claude Desktop, Cursor, Continue, Windsurf, etc.).
Ask your AI assistant things like:
- "Search Hermes Atlas for memory providers"
- "What does the hermes-atlas catalog say about the hermes-agent project?"
- "List the top skills for Hermes Agent"
- "Get the Hermes beginner's guide"
- "Ask the atlas: what's the difference between Hermes Agent and Claude Code?"
All catalog data is fetched live from hermesatlas.com (cached in-memory for 1 hour), so tool answers reflect the current ecosystem, not a stale snapshot.
Status: 0.x, experimental. Breaking changes may happen before 1.0. Batch releases weekly.
Install
Recommended — one command
npx -y hermes-atlas-mcp install --client claude-desktop
Replace claude-desktop with cursor or claude-code as needed. The installer finds the right config file for your OS, merges in the hermes-atlas entry without touching your other MCP servers, and tells you what to do next.
Other flags:
--print— dry-run (shows the diff, writes nothing)--force— overwrite an existinghermes-atlasentry without prompting
To remove:
npx -y hermes-atlas-mcp uninstall --client claude-desktop
Fully quit and reopen the client after either command (closing the window isn't enough — the process needs to restart).
Manual install (if the installer won't work)
Claude Desktop
Find the config file:
- Easiest: open Claude Desktop, go to Settings → Developer → Edit Config. The file opens in your default editor.
- macOS:
~/Library/Application Support/Claude/claude_desktop_config.json - Windows:
%APPDATA%\Claude\claude_desktop_config.json - Linux:
~/.config/Claude/claude_desktop_config.json
Paste this (if the file is empty or doesn't exist) or merge the hermes-atlas entry into your existing mcpServers object:
{
"mcpServers": {
"hermes-atlas": {
"command": "npx",
"args": ["-y", "hermes-atlas-mcp"]
}
}
}
Save. Fully quit Claude Desktop and reopen. The five tools appear in the tool picker.
Cursor
File: ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project). Same JSON snippet as above.
Claude Code
Either use the installer above, or run /mcp inside Claude Code and add through its UI, or hand-edit ~/.claude.json.
