Common questions

Is AI Context Flow safe?

It passed 2 of 2 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 2 months ago, and the latest version (1.0.1) reached the registry 6 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 Business and above.

What can I use instead?

Plurality MCP Server

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.

Why use this?

Memory Studio — a personal knowledge base and second brain where you organize context into memory buckets, review saved content, and manage what your AI agents know.
Save important chats — directly from within Claude, ChatGPT, Cursor, and other AI tools into the relevant memory bucket
Shared persistent memory across all your agents — Claude Code, Lovable, Cursor, OpenClaw and more all access the same context
Semantic search — find relevant memories using natural language, not just keywords
Share buckets with other people — collaborate by giving others access to your context
Works everywhere — any MCP-compatible client can connect

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.

Quick connect (production)

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)

Tools

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

Authentication

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

Using a Personal Access Token

Sign in to the dashboard, open Connect via MCP → Manage tokens
Click Create token, give it a name and optional expiry, copy the plur_pat_… value
Configure your client to send it as a Bearer token:

Authorization: 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.

OAuth details

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)

Client discovers auth server — fetches /.well-known/oauth-protected-resource from Traefik
Client registers — calls /register (Dynamic Client Registration) to get client_id/client_secret. The API Gateway proxies this to Hydra, injecting the mcp:tools scope
User authenticates — browser opens Hydra's login flow, which redirects to the frontend's login/consent pages
Token issued — Hydra returns a JWT access token (RS256, 15min TTL) with the user's ID as the sub claim and mcp:tools scope
Authenticated requests — client includes Authorization: Bearer on all MCP requests
MCP server validates — JWT signature verified locally against Hydra's JWKS public keys (cached 1 hour), mcp:tools scope is checked
API Gateway access — MCP server forwards the Bearer token when calling API Gateway endpoints for data retrieval and storage

Architecture

MCP 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.

Local development setup

Prerequisites

Python 3.11+
uv (Python package manager)
Docker and Docker Compose
Running API Gateway (plurality-backend-api): Handles authentication, OAuth metadata, DCR proxying, and database access
Running Vector Service (plurality-ai-service): Handles semantic search and vector database operations

1. Install dependencies

cd plurality-mcp-server

pip install uv uv sync

2. Configure environment

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

3. Start Docker services (Hydra + Traefik)

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

4. Start the MCP server

uv run uvicorn main:mcp_server --host 0.0.0.0 --port 5051 --reload

Port 5051, not 5050. Traefik listens on 5050 and proxies /mcp to the MCP server on 5051.

5. Verify

# Health check (direct)

curl http://localhost:5051/mcp/health

OAuth metadata (via Traefik)

curl http://localhost:5050/.well-known/oauth-protected-resource

Traefik dashboard (for debugging routes)

open http://localhost:8080

Local client configuration

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:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %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.

Troubleshooting

MCP client gets 401 Unauthorized

Check that Hydra is running: curl http://localhost:4444/.well-known/openid-configuration
Check that the JWT hasn't expired (15min TTL)
Verify HYDRA_ISSUER matches the issuer in the token's iss claim
Ensure the token has the mcp:tools scope

MCP client gets 502 Bad Gateway

The MCP server isn't running on port 5051
Check Traefik logs: docker compose -f ory-hydra/docker-compose.yml logs traefik

Tools return "Error: Backend API returned status 401" </summar
