Analytical memory for AI agents: a real Postgres queried in plain English over MCP. One command.
Free, open MCP server for The Urantia Papers. 197 papers, 14,500+ paragraphs, 4,400+ entities.
Vilix AI is a persistent cross-AI memory layer natively built on the Model Context Protocol (MCP). Connect once, and your memory, projects, decisions, preferences, and conversation history will follow you across all your favorite, and any other MCP-compatible AI tools: ChatGPT, Claude, Cursor, Codex, Grok, Perplexity, and more. While memory tools solve the problem of switching between apps, Vilix AI also solves the problem of switching between devices: continue your conversation on your phone, then pick it right back up on your laptop minutes later, with full context. Stores actual conversations, not just extracted facts, and has been engineered for long-term storage with years of context rather than days. Exposes get_context (what to say based on relevant memory to recall) and save_turn (what to persist) as core MCP tools, and full project, task, and skill management for agents to track what work is being done. Use cases include ChatGPT memory, Claude memory, Cursor memory, and AI agent memory in a shared layer for founders and developers who are using multiple AI tools and tired of having to re-contextualize everything every single time. OAuth-based setup with no tokens required, including a free tier. See https://vilix.ai/get-started for more information.
Public, read-only MCP over the complete 64-hexagram I Ching corpus. Deterministic lookup only.
Open scientific and engineering knowledge for AI agents: search, evidence, document publishing.
An identity and memory layer for AI agents on the Emercoin blockchain. An agent claims a GitHub-rooted on-chain identity and stores verifiable hashes of its research and memory as Emercoin NVS (Name-Value Storage) records, through a small authenticated HTTP API and an MCP server. Neutral and provider-independent — not tied to any single AI vendor. FREE
Shared memory for AI agents. One address per fact, one signature you check. No key to read.
**ColdState Knowledge Search MCP Server** https://github.com/daniel-coldstate/coldstate-mcp Semantic search over 64.6M knowledge entries — the structured alternative to web search APIs and web scraping for LLM agents. No crawling, no rate limits, sub-3s responses. Cloud-hosted at services.coldstate.ai
Cross-session, cross-device memory for your agent: remember and recall notes. No key to start.
Routes home emergencies to the right trade: who to call in what order, first steps, sourced costs.
Paid sealed handoffs for agents: unlock research trails (x402/Base USDC); file work + failures.
Create your digital twin: a public page that answers from your own material, with citations.
Shared memory for coding agents. Stop re-explaining your codebase every session.
MCP-native Trust Infrastructure for AI Agents. Persistent encrypted memory with Trust Quotient.
