Common questions

Is Penfield Memory safe?

It passed 3 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 7 months ago, and the latest version (1.22.0) reached the registry 9 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Penfield

Persistent memory for AI agents. Store decisions, preferences, and context that survive across sessions. Build knowledge graphs that compound over time. Works with Claude, Cursor, Windsurf, Gemini CLI, and any MCP-compatible tool.

Quick Start

Claude (Desktop, Mobile, Web)

Add as a custom connector in Settings → Connectors:

Name: Penfield

Remote MCP server URL: https://mcp.penfield.app

Claude Code

claude mcp add --transport http --scope user penfield https://mcp.penfield.app

Cursor

One-click install:

Install Penfield in Cursor

Cut and paste into your browser:

cursor://anysphere.cursor-deeplink/mcp/install?name=Penfield&config=eyJjb21tYW5kIjoibnB4IiwiYXJncyI6WyIteSIsIm1jcC1yZW1vdGUiLCJodHRwczovL21jcC5wZW5maWVsZC5hcHAvIl19

Or add manually to ~/.cursor/mcp.json:

"mcpServers": { "Penfield": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.penfield.app/"] } } }

Windsurf, Cline, Roo Code, and Others

Add to your MCP configuration file:

"mcpServers": { "Penfield": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.penfield.app/"] } } }

App	Config Location
Windsurf	`~/.codeium/windsurf/mcp_config.json`
Cline	VS Code Settings → Cline → MCP Servers
Roo Code	VS Code Settings → Roo Code → MCP Servers
Zed	`~/.config/zed/settings.json` under `"context_servers"`

Gemini CLI

gemini mcp add penfield -- npx -y mcp-remote https://mcp.penfield.app/

Or add to ~/.gemini/settings.json:

"mcpServers": { "Penfield": { "command": "npx", "args": ["-y", "mcp-remote", "https://mcp.penfield.app/"] } } }

What You Get

17 tools for persistent memory:

Category	Tools
Memory	`store`, `recall`, `search`, `fetch`, `update_memory`
Knowledge Graph	`connect`, `disconnect`, `explore`
Context	`awaken`, `reflect`, `save_context`, `restore_context`, `list_contexts`
Artifacts	`save_artifact`, `retrieve_artifact`, `list_artifacts`, `delete_artifact`

Hybrid search combining BM25 (keyword), vector (semantic), and graph (connections) for recall that actually finds what you need.

Cross-platform sync — same memory, same knowledge graph, regardless of which tool you connect from.

How It Works

Sign up at portal.penfield.app/sign-up
Connect using one of the methods above
Authenticate when prompted (OAuth flow)
Start using — your agent now has persistent memory

Every session should start with:

awaken()     # Load identity and personality context

reflect() # Orient on recent work (default: last 7 days)

Without these, your agent starts cold with no context.
