Overview

AI-generated overview

Valta is a remote MCP notes and memory service that gives assistants one shared Markdown vault usable across Claude, ChatGPT and other MCP clients.

What you can do
  • Read and write notes in a shared Markdown vault from an MCP client.
  • Keep memory or context that several assistants can reuse.
  • Work with the same vault across different MCP clients such as Claude and ChatGPT.
  • No individual tools are documented in the supplied material, so exact capabilities are unconfirmed.
When to use it
Useful when you want several AI assistants to share one persistent notes and memory store instead of each keeping its own context, and you are comfortable with a hosted service holding that content.
Requirements
A remote MCP endpoint at valta.si over streamable HTTP; no local package or runtime is needed. OAuth authentication is required, so you need a Valta account and a client that supports OAuth. Network access to the service is required.
Before you install
Notes and memory are stored on a third-party hosted service, so anything you put in the vault leaves your machine. Access is granted through OAuth, so review which scopes and account you authorize. The assistant can likely create and change notes in the shared vault, so changes may affect other clients using the same vault.

Installation

In SourceWeft

  1. Open Valta in the dashboard and add it to a workspace.
  2. Connect the required 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/si.valta%2Fvalta/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. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
