Memento MCP

A parallel coding agent memory server that manages file claims to prevent overwrites, maintaining a shared tracker and working memory for a fleet of agents running on user machines.

Endpoint and access

Server-provided instructions

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

Claim a path before you edit it; ask who holds it when a claim fails.

Tools

3 advertised

claim
Advertised by the server during the last successful anonymous check.

Claim a path before editing it, so parallel agent sessions do not overwrite each other. ok false names the session that holds it; then work on something else or wait. A claim lasts 24 hours; claim again to renew.

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 memento-mcp-overflow https://overflow.games/memento/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 memento-mcp-overflow --url https://overflow.games/memento/mcp

Cursor

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

Cline

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

VS Code

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