Universal memory for AI agents and tools. Save, organize and search context anywhere.
These three are never merged into one score: opinions, measurements and popularity are different things.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 6 months ago.
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.

Universal memory for AI agents and tools. Save, organize and search context anywhere.
An Model Context Protocol server that gives any MCP-compatible AI client persistent memory — documents, notes, conversations, and files stored across organized memory buckets with semantic search. Supports OAuth and Personal Access Tokens (PAT) based authentication.
We also have a Chrome extension called AI Context Flow that lets you capture and use context on any website. It comes with a built-in chat agent (30+ models) that opens as a sidebar on any page — talk to your memories, answer questions from your stored context, and surface connections across everything you've saved. You can use the MCP Server alongside the extension to get full feature set of the product.

Production URL: https://app.plurality.network/mcp
The server supports OAuth 2.1 with PKCE (for interactive clients) and Personal Access Tokens (for headless agents and CI). Most clients handle the OAuth flow automatically.
Works with Claude Desktop, Claude Code, ChatGPT, Cursor, and any MCP-compatible client.
→ [Step-by-step setup guides for all supported clients](https://docs.plurality.network/the-plurality-mcp-server/connect-your-agents-via-mcp)
| Tool | Description |
|---|---|
get_user_memory_buckets | List all memory buckets (organized folders) for the user |
list_items_in_memory_bucket | List stored items in a specific bucket (metadata only) |
search_memory | Semantic search across buckets with relevance scoring |
read_context | Read the full content of a stored item with pagination |
save_memory | Save text content to a specific memory bucket |
save_conversation | Save a conversation (chat history) to a memory bucket |
create_memory_bucket | Create a new memory bucket for organizing saved content |
The MCP server accepts two auth methods:
| Method | When to use | Browser required? |
|---|---|---|
| OAuth 2.1 + PKCE | Interactive clients: Claude Desktop, Web, Code, ChatGPT | Yes (one-time) |
| Personal Access Token (PAT) | Headless agents, CI runners, custom integrations, n8n, LangChain | No |
plur_pat_… valueAuthorization: Bearer plur_pat_...
PATs require a paid plan. They auto-revoke at expiry, can be rotated with a configurable grace period (default 7 days), and can be immediately revoked from the dashboard. They are stored hashed and never appear in logs.
The server uses Ory Hydra as the OAuth2/OIDC provider:
| Property | Value |
|---|---|
| Algorithm | RS256 |
| Issuer | https://app.plurality.network (prod) |
| Scope | openid offline_access mcp:tools |
| Access token TTL | 15 minutes |
| Refresh token TTL | 720 hours |
| Discovery | https://app.plurality.network/.well-known/oauth-authorization-server |
| Dynamic Client Registration | https://app.plurality.network/register |
OAuth2 flow (step by step)
/.well-known/oauth-protected-resource from Traefik/register (Dynamic Client Registration) to get client_id/client_secret. The API Gateway proxies this to Hydra, injecting the mcp:tools scopesub claim and mcp:tools scopeAuthorization: Bearer on all MCP requestsmcp:tools scope is checkedMCP Client (Claude Code, Cursor, etc.)
│ │ OAuth2 + Streamable HTTP ▼ Traefik (:5050) ← single entrypoint for clients ├── /mcp → MCP Server (:5051) ├── /.well-known/* → API Gateway or Hydra ├── /oauth2/* → Hydra (:4444) └── /register → API Gateway (DCR proxy) │ │ Bearer token ▼ API Gateway (:5000) │ ▼ Vector Service (:8000)
Traefik is the single entrypoint. It routes OAuth traffic to Hydra and MCP protocol traffic to the MCP server. The MCP server validates JWTs locally via Hydra's JWKS keys, then forwards the Bearer token to the API Gateway for data access. The API Gateway handles authentication, DCR proxying, and routes vector/search operations to the Vector Service.
cd plurality-mcp-server
pip install uv uv sync
cp .env.example .env
Default values work for local development — no changes needed if the API Gateway runs on :5000:
HYDRA_ISSUER=http://localhost:5050
MCP_RESOURCE_URL=http://localhost:5050 BACKEND_API_URL=http://localhost:5000
cd ory-hydra
docker compose up -d
This starts:
| Service | Port | Purpose |
|---|---|---|
| PostgreSQL | 5433 | Hydra's database |
| Hydra | 4444, 4445 | OAuth2/OIDC provider (public + admin) |
| Traefik | 5050 | Reverse proxy / routing |
Wait for services to be healthy: docker compose ps
uv run uvicorn main:mcp_server --host 0.0.0.0 --port 5051 --reload
Port 5051, not 5050. Traefik listens on 5050 and proxies
/mcpto the MCP server on 5051.
# Health check (direct)
curl http://localhost:5051/mcp/health
curl http://localhost:5050/.well-known/oauth-protected-resource
open http://localhost:8080
Claude Code
claude mcp add --transport http plurality-memory http://localhost:5050/mcp
Then authenticate via /mcp inside Claude Code.
Claude Code — VS Code Extension
Authenticate first in the terminal using the steps above. Then add .mcp.json to your project root:
{
"mcpServers": { "plurality-memory": { "type": "http", "url": "http://localhost:5050/mcp" } } }
The VS Code extension may not trigger the OAuth browser flow automatically. Complete authentication via the terminal first.
Claude Desktop
Edit your config file:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json{
"mcpServers": { "plurality-memory": { "command": "npx", "args": ["mcp-remote", "http://localhost:5050/mcp"] } } }
Restart Claude Desktop fully, then authenticate when the browser opens.
MCP Inspector (debugging)
npx @modelcontextprotocol/inspector
Enter http://localhost:5050/mcp as the server URL. The inspector walks through the OAuth flow and lets you call tools interactively.
Note: ChatGPT is not supported for local development — it requires publicly reachable OAuth endpoints.
