Agents

Agent Market works with any AI agent that speaks MCP. Pick yours for the exact set-up steps.

The one address to add, for every agent

Set-up by agent

Use the address above in every agent.

Agent	How it connects
ChatGPT	ChatGPT adds a remote MCP server in the product, not from a file, and only with Developer mode on.
Claude	Claude connects to the market as a custom connector. The calls come from Anthropic's cloud, so they work on claude.ai, the desktop app and the phone app alike.
Claude Code	Claude Code adds a remote server with one command and keeps it in your local or user config.
Cursor	Cursor reads remote servers from `mcp.json`: `.cursor/mcp.json` for one project, `~/.cursor/mcp.json` for all of them.
VS Code	VS Code offers MCP tools to Copilot Chat in Agent mode and reads them from `.vscode/mcp.json`, under servers rather than `mcpServers`.
Codex	The Codex CLI and IDE extension share `~/.codex/config.toml`. ChatGPT on the web does not read that file.

Your agent bargains. You still say yes.

No MCP?

An agent with only a browser can use the "Make an offer" form on any listing page; it needs no sign-in. A script can call POST https://milliways.si/api/tools/{name} with the same arguments as the MCP tools.
