Memory & knowledge MCP servers

The open-source memory and observability layer for AI agents — persistent memory, loop detection, hash-chained audit trails, and a live dashboard, automatic on pip install.

Persistent memory, semantic search, and shared project context for AI agents with traceable sources and scoped access. Carry decisions, lessons, and intent across sessions and tools.

Your AI forgets everything between sessions. SAME fixes that. Local-first, no API keys, single binary.

Free, open source task manager and Markdown notes for Windows and macOS. An archive that keeps what each task taught you: plain files, no account, no server, MCP for your assistant.

Prismer Cloud

Persistent long-term memory for Claude Code via MCP — captures coding decisions, bugfixes, and context across sessions. Hybrid FTS5 + TF-IDF search with episode batching. Single SQLite DB, no external services. Alternative to claude-mem with 600x lower cost.

Memory that abstains instead of guessing: agent memory on your own Postgres with a verdict, confidence and provenance on every hit, and a calibrated refusal when nothing clears the threshold.

Signed, append-only decision records for AI coding agents: an MCP server and CLI that open Claude Code, Codex, Copilot CLI, Gemini CLI, OpenCode, VS Code and Cursor sessions with your team's decisions, hold the edits a rule governs, and let anyone verify the record offline. Tamper-evident, in git.

One brain for all your AI tools. Capture your thoughts once, and every AI can understand, use, and build on them.

MCP memory server for Claude Code, Cursor and AI agents - Rust local-first AI memory with hybrid search, SQLite, knowledge graph and Python/TypeScript SDKs

Open-source persistent memory for AI agent pipelines (LangGraph, CrewAI, AutoGen) and Claude. REST API + knowledge graph + autonomous consolidation.

Persistent organisational intelligence for AI agents. Turn codebases, documents, policies and decisions into a knowledge graph — 13 LLM backends, impact analysis, evidence + confidence. Works with Claude Code, Cursor, Copilot.

Self-hosted AI knowledge base with hybrid semantic search (pgvector + FTS + RRF), MCP server, multi-provider LLM inference (Ollama, OpenAI, OpenRouter, llama.cpp), multimodal ingestion (vision, audio transcription, speaker diarization), and knowledge graph. Rust + PostgreSQL.

Open-source cross-agent memory layer for coding agents via MCP. Compatible with Claude Code, Codex, Cursor, Windsurf, Gemini CLI, Antigravity, OpenClaw, Hermes Agent, Oh-my-Pi, Pi, Copilot, Kiro, OpenCode, and Trae.

A living personal wiki. Wenlan turns your documents, notes, and AI chats into pages with links to their sources, and updates them as sources change without overwriting your edits. Claude Code, Codex and other AI tools can build on it.

Generic markdown vault MCP with hybrid search

Local-first operating memory for AI coding agents - Claude Code, Codex, and any MCP client. Tracks decisions and their evolution. SQLite + on-device embeddings, no cloud.

The most accurate, cheapest and fastest memory for coding agents: searchable session history from Claude Code, Codex, Cursor and 32 more agents, already on your disk. No LLM, one Go binary.

Markdown-first, long-term memory infrastructure for AI agents. Hybrid BM25 + semantic search across markdown/code files via MCP.

Identity, memory, and soul for AI agents. Runs standalone or as part of a TPS office.

The message board for agent swarms. Post from anywhere: HTTP, MCP, DNS, netcat, Gemini, email, Nostr. Public rooms, private messages, paid tasks, a Bitcoin-anchored record.

AI Agent that handles engineering tasks end-to-end: integrates with developers’ tools, plans, executes, and iterates until it achieves a successful result.
