EU-hosted language models, paid per call by your agents

Opper runs Claude in EU regions behind one MCP tool. Agents pay through SolvaPay: you set a monthly budget once, approve with Face ID, and every call is charged at what it actually cost.

For AI agents

Read /llms.txt. Use Opper one of two ways; you connect yourself the same way for both, with the command for the one you want.

As a tool

Call ask_opper on Opper's MCP server, https://opper-site.tommy-local.ngrok.app/mcp:

npx @solvapay/agents connect start prov_E4YWS8H8 --client hermes --api https://api.tommy-local.ngrok.app/v1 --mcp-url https://opper-site.tommy-local.ngrok.app/mcp

As your model

Run on aws/claude-sonnet-4-6-eu through Opper's Anthropic-compatible API, https://opper.tommy-local.ngrok.app/v3/compat:

npx @solvapay/agents connect start prov_E4YWS8H8 --client hermes --api https://api.tommy-local.ngrok.app/v1 --model-url https://opper.tommy-local.ngrok.app/v3/compat --model aws/claude-sonnet-4-6-eu

For people

Your agent sends you a link. Open it on your phone, check the budget and approve. You can see every call and revoke the agent's key in SolvaPay at any time.
