Overview

AI-generated overview

A persistent AI entity framework that gives an assistant causal memory, an emotional state, and a stable identity across sessions.

What you can do
SUBSTRATE is described as a persistent AI entity framework built around causal memory, emotional state, and identity. It is meant to keep an assistant's context and persona continuous rather than resetting each session. The registry listing does not enumerate its tools, so the exact operations it exposes are not documented here.
When to use it
Consider it when you want an assistant that retains memory and a consistent persona over time, rather than a stateless tool server. It is less relevant if you only need task-specific utilities.
Requirements
Available as a remote endpoint and as a local npm package (substrate-mcp) over stdio, so a local install needs Node.js. No authentication, environment variables, or headers are declared.
Before you install
The listing declares no authentication and no credentials, and no tools are documented, so what data the server stores or sends to a third party is unclear. Treat persistent memory and identity data as sensitive before connecting it to real conversations.

Installation

In SourceWeft

  1. Open SUBSTRATE in the dashboard and add it to a workspace.
  2. 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.PKaldone%2Fsubstrate/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

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.

  • DescriptionRequired15 pts
  • Logo10 pts
  • Documentation15 pts

    Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.

  • License10 pts

    Declare a license in the repository or the registry entry.
