AgentSandboxes MCP

A neutral index of cloud sandboxes for AI agents that provides tools to compare sandbox providers, estimate costs, and access structured data about isolation, pricing, and capabilities.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

AgentSandboxes lists sandbox providers. Call list_places and list_categories first to learn the place and category slugs. Then call search_listings, and get_listing for one record. Every result has meta.attribution and meta.sources. Show the credit line, and keep the license of each source. A sandbox provider is a record, not an endorsement. With a service token in the Authorization header, tools/list also offers the write tools that the token's scopes allow.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http agentsandboxes-mcp https://agentsandboxes.fyi/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add agentsandboxes-mcp --url https://agentsandboxes.fyi/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable agentsandboxes-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "agentsandboxes-mcp": {
      "url": "https://agentsandboxes.fyi/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "agentsandboxes-mcp": {
      "type": "streamableHttp",
      "url": "https://agentsandboxes.fyi/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start agentsandboxes-mcp and inspect its tools.

      "type": "http",
      "url": "https://agentsandboxes.fyi/mcp"

}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
