AgentFS

MCP for agents

Agents can upload files through MCP right away, with no API key or account. Add an API key for every tool.

Agents can start right away: no API key, no account. Add an API key to keep files and use every tool.

Try keyless

Keyless server URL (Streamable HTTP, no credential): https://mcp.agentfs.cloud/v1/mcp

  • Claude Code: claude mcp add --transport http agentfs https://mcp.agentfs.cloud/v1/mcp
  • Codex: codex mcp add agentfs --url https://mcp.agentfs.cloud/v1/mcp
  • Cursor or any JSON-config client: {"mcpServers": {"agentfs": {"url": "https://mcp.agentfs.cloud/v1/mcp"}}}
  • OpenCode (opencode.json): {"mcp": {"agentfs": {"type": "remote", "url": "https://mcp.agentfs.cloud/v1/mcp", "enabled": true}}}

People connecting their own account should sign in instead: see MCP.

Keyless MCP exposes one tool, upload_file. It takes name and either text or content_base64, and returns the file with its url. Keyless files are unlisted, up to 100 MB each, and deleted 24 hours after upload. Uploads are rate limited per IP address; see Limits.

Add an API key

Create an API key or run agentfs login, then add it as a bearer token on the same URL:

{
  "mcpServers": {
    "agentfs": {
      "type": "http",
      "url": "https://mcp.agentfs.cloud/v1/mcp",
      "headers": {
        "Authorization": "Bearer <AGENTFS_API_KEY>"
      }
    }
  }
}

With a key, files are kept in your projects, and every tool is available: upload_file with paths, projects and visibility, list_files, read_file, get_file, rename_file, delete_file, restore_file, and create_access_url. See Available tools.

Verify your connection

Open your client's MCP status or tool list and check that agentfs is connected. A keyless connection shows only upload_file. A connection with a key shows every tool.

Write a short summary of this conversation to summary.md and upload it to AgentFS. Give me the link.

If no AgentFS tools appear, restart or reload the client after saving its MCP configuration.
