Agents
Add Lagias to your agent.
Lagias is an MCP server. Add it as a connector and sign in, or use an API key with your client’s config file. Both reach the same tools.
Add it as a connector
In Claude (claude.ai or the desktop app) open Settings → Connectors → Add custom connector, paste the URL below, and leave the two OAuth fields empty. Claude registers itself. You approve the connection on a Lagias screen that names exactly what it may do, and you can revoke it there at any time. No key is created and none is needed.
https://mcp.lagias.com/mcp
Any client that speaks OAuth for MCP works the same way. Your plan, credits and limits are the same on both paths.
Or connect with a key
A key is what your agent sends as its Authorization header. Create an account, make a key in the dashboard, then paste it where a config says <your key>.
Run in a terminal. Claude Code stores the server for that project. Prefer no key? Drop the --header and run /mcp to sign in instead.
claude mcp add --transport http lagias https://mcp.lagias.com/mcp --header "Authorization: Bearer <your key>"
Paste into .cursor/mcp.json at the project root (or merge under mcpServers).
{
"mcpServers": {
"lagias": {
"url": "https://mcp.lagias.com/mcp",
"headers": { "Authorization": "Bearer <your key>" }
}
}
}Paste under mcp.servers in ~/.openclaw/openclaw.json, or add via Settings → MCP (Streamable HTTP).
{
"mcp": {
"servers": {
"lagias": {
"url": "https://mcp.lagias.com/mcp",
"transport": "streamable-http",
"headers": { "Authorization": "Bearer <your key>" }
}
}
}
}Any HTTP MCP client that accepts a URL and Authorization header.
{
"type": "http",
"url": "https://mcp.lagias.com/mcp",
"headers": { "Authorization": "Bearer <your key>" }
}Before you paste anything
Do I need an API key?
Not if you add Lagias as a connector. Claude (claude.ai or the desktop app) signs in over OAuth. A key is the other path: paste it into your client’s config file. Both reach the same tools.
Where do I get a key?
Create an account at app.lagias.com. After you sign in, the dashboard is where you make a key. The secret is shown once at creation and cannot be shown again.
Which clients work?
Any client that speaks MCP over HTTP. Claude Code, Cursor and OpenClaw have copy-paste configs on this page. Other clients take the same URL and an Authorization header.
Does the free tier work over MCP?
Yes. The free tier needs no payment details. Current factor values start with Plus. Everything else, including the verdict, is on every plan.
