"Understanding OAuth 2.0 Protocol" matching MCP connectors:

Shared, verifiable memory for AI agents and robots: signed tokens that resolve and verify offline.

The personal context layer for AI: your profile and files, read by any MCP client over OAuth.

People + life-in-days knowledge for AI agents. Public MCP; x402 on Base; OAuth for private tools.

Zero-key temporary JSON database for agents: one tool call, no signup, no OAuth, no API keys.

Hosted ambient memory for AI agents. Retrieve context and save notes via MCP tools with OAuth.

Search everything you save: YouTube, articles, podcasts, PDFs, Notion, Obsidian. API key or OAuth.

AI-native project management plus a persistent memory & knowledge layer for agents: live tasks, sprints, AI risk scores, burnout signals, project memory, decision logs, and semantic knowledge search — 100+ tools via OAuth 2.1, free plan.

The high-surprisal facts AI models miss — an accurate, up-to-date understanding of world state.

Website analyses and Knowledge Packs for the authenticated account via OAuth 2.1 + DCR.

Private journal MCP server to search, analyze, and create Dabble Me entries securely via OAuth.

Illumora Craft — evidence-augmented prompt compile for agents via remote MCP (OAuth) or local stdio.

StremAI MCP: shared memory for AI coding agents. Connected agents can recall. OAuth + local stdio.

private by default journaling, self-understanding, reflective songs, books, playlists, insights.

Private memory layer — one library your notes, docs, and chat history live in, that any AI tool (Claude, Cursor, ChatGPT) connects to over MCP instead of re-pasting context. Semantic search over your own documents with citations; every memory is a document you can read, edit, and delete. ~80% fewer context tokens than pasting your library. Connect via OAuth (sign in when prompted) — get started at

OAuth-protected, read-only-by-default MCP server for provenance-labeled QuillCaddie project memory.

MCP protocol requiring task acceptance and provenance tags. Self-hosted only - see README.

Scraps Kitchen gives any AI agent a persistent, household-aware kitchen memory. Unlike generic chatbot recall, Scraps maintains structured cooking data: what's in your fridge (with freshness tracking), who you cook for (with allergens, dietary restrictions, and preferences), your recipe collection (with cook notes and per-diner ratings), your shopping list, and your kitchen equipment. 27 tools across 6 domains let agents read kitchen context, suggest meals that respect dietary safety, update the pantry after cooking, and build a history of what works for your household. Every interaction makes the data richer. Cooking history, preference signals, kitchen awareness = better suggestions next time. All tools work via oAuth and a free scraps.kitchen account.

Truth-validated, SHA-512-sealed AI memory for Claude & Cursor. Free tier, OAuth, 38 tools.

Persistent memory and vector search for AI agents. Hosted, OAuth-protected via Google sign-in.

Persistent memory for AI agents with OAuth-backed hosted MCP access.
