Spritefetch MCP

An MCP server that allows AI agents to search, retrieve metadata, and download CC0-licensed 2D sprite sheets and tilesets for game development. It provides tools for finding assets by query, getting detailed asset records including slicing data, and downloading files with verified checksums.

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.

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 spritefetch-mcp https://api.spritefetch.dev/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 spritefetch-mcp --url https://api.spritefetch.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable spritefetch-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "spritefetch-mcp": {
      "url": "https://api.spritefetch.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "spritefetch-mcp": {
      "type": "streamableHttp",
      "url": "https://api.spritefetch.dev/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start spritefetch-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "spritefetch-mcp": {
      "type": "http",
      "url": "https://api.spritefetch.dev/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http spritefetch-mcp https://api.spritefetch.dev/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "spritefetch-mcp": {
      "url": "https://api.spritefetch.dev/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "spritefetch-mcp": {
