Noodle Seed
Noodle Seed
Platform for making software agent-ready, turning existing product workflows into secure MCP apps and embedded conversational assistants.
Key features
- MCP App Deployment: Build and deploy headless versions of an existing SaaS product as MCP Apps that any MCP client can call.
- Embedded Assistant Runtime: Drop a conversational assistant into a product or public site, running on the same runtime that governs agent actions.
- Identity and Permission Carrying: Customer and account context travels with every request, and agents operate under the roles, scopes, and credential rules the product already enforces.
- Single Control Plane: Run, inspect, and update every agent experience from one place, with policies and audit logs on higher tiers.
- Managed Secrets and Rollback: Credentials are managed for you, and deployment history lets teams roll back a release.
- Solution Starters: Ready-made starting points for travel and booking, customer support, and HR or employee requests, including a working travel concierge example.
- Pooled Usage Billing: MCP calls are pooled monthly across every app on a billing account instead of being priced per seat.
- Local-First Development: Develop and prove a workflow locally without an account before deploying it.
Best for
- Agent-Ready SaaS: Expose an existing product's core workflows so ChatGPT, Claude, or Copilot users can complete them without leaving the assistant.
- Travel Concierge: Let customers search and book flights or stays conversationally, built from the travel and booking starter.
- Customer Support Deflection: Handle account-specific support requests through an embedded assistant that respects the caller's real permissions.
- HR and Employee Requests: Route internal requests such as time off or policy questions through a governed conversational interface.
- Conversational Commerce: Open a public marketing site to AI-driven discovery, lead capture, and purchase flows before signup.
- Enterprise Agent Governance: Centralise policies, audit logs, and private connectivity for every agent experience an organisation runs.

Self-hosted persistent memory layer that lets Claude, ChatGPT, Cursor, and any MCP client share the same evolving context.
Key features
- Cross-Tool Persistent Memory: One memory layer shared by Claude, ChatGPT, Cursor, Codex, and any MCP client.
- Semantic Recall: Retrieves memories by meaning rather than exact wording, so different phrasings still surface the right note.
- Memory Graph (v2): Memories link automatically or explicitly, and recall can follow hops to surface related context.
- Notion Sync: Connect a Notion workspace and shared pages sync into memory nightly or on demand, staying current as they change.
- Self-Hosted on Cloudflare Workers: Deploy to your own account in about two minutes — memory stays under your control, not a vendor's.
- MCP Tool Set: remember, append, update, recall, list_recent, forget — usable directly from any MCP client or the brain CLI.
- Graceful Degradation: If Vectorize is missing, recall falls back to keyword search with a clear notice and a /health endpoint reports index status.
- Dashboard with Graph View: Web dashboard for browsing memories, managing integrations, and exploring the memory graph visually.
Best for
- Consistent Assistant Context: Keep the same project background, preferences, and decisions across Claude, ChatGPT, and Cursor without repeating yourself.
- Team Knowledge Capture: Use the CLI or MCP tools to store product decisions or interview notes so any AI tool can recall them later.
- Notion-Backed Memory: Share Notion pages with the connection so meeting notes and specs are automatically retrievable by any AI client.
- Self-Hosted Compliance: Run memory in your own Cloudflare account when data cannot leave your infrastructure or be locked in one AI platform.
- Developer Journaling: Save decisions and rationale from your terminal (`brain remember`) and recall them from Cursor while coding.
- Research Continuity: Store leads, references, and open questions once and surface them across whichever assistant you're using that day.
