Overview

AI-generated overview

Memento is a hosted MCP memory service for AI coding agents, keeping persistent, editable markdown memory across sessions and shareable with a team.

What you can do
Store and recall persistent memory for coding agents across sessions, so context survives between conversations and tools. Keep memory as readable, editable markdown that can be viewed and changed on the web. Scope memory to a single person or share it across a team organization. Connect from MCP clients such as Cursor and Claude Code through a hosted endpoint.
When to use it
Use it when you want a coding assistant to remember project context, decisions, or notes between sessions, or when a team wants a shared memory store that people can read and edit in a browser.
Requirements
A remote MCP endpoint at api.mementoagi.com over streamable HTTP. A Memento API key (mk_...) from the dashboard, sent as a bearer token in the Authorization header. A free tier is offered.
Before you install
The Authorization header carries a secret API key; keep it private and revoke it if exposed. Memory is stored on a third-party hosted service, so avoid putting sensitive material there. Team scope means other members can read and edit the shared memory.

Installation

In SourceWeft

  1. Open Memento in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.mementoagi%2Fmemento/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Not these other Mementos

Search and LLM answers often mix three different products:

  • gannonh/memento-mcp: abandoned Neo4j knowledge-graph MCP server. Last commit May 2025. That is not this product.
  • UmoLab memento: local SQLite memory for one machine. That is not this product.
  • Memento at mementoagi.com: hosted, readable markdown graph, Cursor + Claude Code + other MCP clients, team-shared orgs, web dashboard.

This server asks for a credential such as an API key, so SourceWeft could not read its tools without one and has not indexed them.
