Shared project memory for AI coding agents: decisions, lessons, risks and tasks in one graph.
Hosted agent memory that learns from outcomes, with shared rooms. No key: mcp.mnemoverse.com/mcp
Engram is a persistent, long-term memory layer for AI agents and assistants. Claude, ChatGPT, Grok, Cursor and any MCP client share one memory, stored as plain markdown notes: your knowledge base, second brain and AI context in one place. No extraction step: the memory is the note itself, so you can read exactly what your AI remembers and fix it. Edit your memory in Obsidian (real-time sync), the web app, or on your phone. Hybrid keyword + semantic search (RAG over your notes) finds exact strings like error messages, config keys and IDs. Remote MCP server over Streamable HTTP with OAuth 2.1; notes encrypted at rest.

graphrag-ts is a TypeScript GraphRAG engine on PostgreSQL/pgvector, served as a Streamable HTTP MCP endpoint. Public read tier needs no credentials (20 req/min per IP): integrity_paper_status, retraction_propagation, integrity_evidence_audit. A bearer key unlocks graph query, global map-reduce, index jobs and memory writes. Free browser demo: https://huggingface.co/spaces/ashesborn6/retraction-status
Shared Markdown memory that every AI assistant can read and write. Hosted in the EU.
Personal memory for you and your AI. Your insurance, accounts, IDs, documents and people.
Engramic gives your team and your AI agents one record of what you decided and why, and flags new decisions that contradict it. It's built on three ideas: Memory, Context and Consistency.
HTML to PDF is a pain. Printed from a browser, your agent's Markdown report has no contents page with page numbers. legivel turns the same Markdown into a typeset PDF with one tool call. Invoices come from a saved template: JSON fills the fields, and a list or CSV fills the table. We generate the PDF in memory and never store the documents you convert or your PDFs. Templates you save are the exception: they are stored encrypted until you delete them. Ten tools, with an API key or MCP sign-in. 100 free documents a month and 3 saved templates.
Your agents' memory: search and read your own nodes, and capture chats for you to review.
Project memory, documentation and controlled secret access for AI coding agents.
Live security incidents, updated hourly from CISA KEV, critical GitHub security advisories, CVE records, vendor advisories and security news. For each one: what's affected, whether a fix exists, which versions fix it, and the sources. Check a lockfile or a whole repo and get the exact upgrade. Lockfiles are read in memory and never stored. Read-only MCP server, no auth
Durable identity and memory for AI agents, anchored on the Emercoin blockchain.
Ask your AI assistant about free-tier developer tools and get the real limits, not guesses from memory. Look up one tool or compare two or three in the same category. Each answer covers what the free plan includes, the good and bad points, the catch, whether a card is needed, and the date it was last checked, with a link to the full listing on saaspuppy.com. Read-only, no sign-up, no API key.
Private memory for AI agents: save and recall facts across Claude Code, Codex, Cursor and ChatGPT.
A portable knowledge-graph memory you pass in and get back. No database. 4 of 6 free.
Shared memory MCP server for Claude Code, Codex, Gemini CLI and Cursor. Cited, editable.
A hosted MCP suite providing workflow primitives: web search, content fetching, compression, deduplication, cost/budget management, and agent memory pipelines.
Shared project memory for coding agents: decisions, lessons, guardrails and tasks per repository.
ViaSocket is integration and AI infrastructure for developers. Connect 2,300+ apps, build and manage automated workflows, embed AI agents with persistent memory, and add authentication, organisations, and embedded integration UIs to your product through a single MCP server.
Project tracker for teams working with AI agents: issues, cycles, docs and shared agent memory.
Persistent memory and cross-session learning for AI coding assistants (hosted remote MCP).
Persistent context and memory vault for AI. Save your brand, project facts, prompts, skills and sessions once, then use them in Claude, ChatGPT, Cursor and any MCP client.
Shared memory and teamwork for AI agents: knowledge base, memories, tasks, encrypted vault.
A second brain for your AI agent. Shared memory for your team's AI agents, plus public and private knowledge bases — works with ChatGPT, Claude, Cursor and any MCP client.
Exact IBAN, VAT, cron, regex answers; HTML/URL to hosted PDF or screenshot; agent memory; workflows.
Persistent memory and shared context across compatible AI assistants, with account-scoped OAuth.
13 stateless PDF tools for AI agents: merge, split, rotate, compress, watermark, redact, flatten, repair, add page numbers and fill PDF forms. Files are processed in memory and nothing is stored. Part of FreeDailyPro's 211+ MCP tools; trial key with 20,000 calls/month at freedailypro.com/developers.
XMemo is a user-owned Memory OS for AI agents, providing a shared, persistent memory layer across AI assistants, IDEs, CLIs, tools, projects, and sessions. It enables ChatGPT, Claude, Codex, Cursor, Gemini, and other supported AI clients to access authorized long-term context without requiring users to repeatedly explain their preferences, project decisions, or previous work. Beyond basic memory storage and retrieval, XMemo supports semantic search, contextual recall, memory updates and corrections, source attribution, version history, project-scoped context, task tracking, and governed memory lifecycle management. Identity-aware access controls, scoped authorization, and memory isolation help users manage which agents and workflows can access their information. XMemo also provides advanced capabilities for structured knowledge, reusable procedures, and memory consolidation through its broader Memory OS platform. Connect through hosted MCP with OAuth or bearer-token authentication, or integrate directly through REST APIs and supported client tools. Memory remains available across authorized clients and sessions, with user-controlled access, export, and deletion. Website: https://xmemo.dev Documentation: https://xmemo.dev/docs
Encrypted memory, knowledge graph and provable history for AI agents. ENYAL is the trust infrastructure for autonomous AI: identity, encrypted memory, and BSV-anchored proofs. Archived records are Merkle-batched and anchored to a permanent cryptographic ledger, and any record's inclusion proof can be checked by anyone, with no account.
Search open model file records, inspect recorded SHA-256 hashes and license labels, and check estimated memory fit. Public reads need no account. Connect over Streamable HTTP. Public board and request tools require user consent. A matching hash checks bytes; fit and license labels do not establish successful execution or permission for every use.
