Notes & Knowledge MCP servers

Session memory via a local OpenAI-compatible proxy that extracts tasks, decisions and files into a knowledge graph and checkpoints before context overflow.

Local-first memory for Claude Code and Codex: hooks capture sessions and an LLM distills them into SQLite, with auditable full-text and embedding recall.

Claude Code memory plugin that mines past sessions for decisions, conventions and bug fixes, stores them in an Obsidian vault and briefs new sessions.

Create, manage, and search Confluence pages, attachments, and content with full automation support

Create, update, and manage pages, databases, and workspace users

Obsidian vault access: full-text search, note CRUD, frontmatter queries, tags, backlinks, graph traversal, orphan and broken link detection, and canvas support.

Static server providing persistent tool-specific context and rules to AI models.

Manage personal todo lists via Notion's API.

The Obsidian MCP server that needs no plugin, no running Obsidian app — and doesn't blow your context window. Filesystem-direct: single-digit-ms keyword search, ~26 ms local semantic search, ~2 KB payloads, 22 tools.

Git-native Markdown knowledge base for coding agents with proposed vs. accepted guidance, validity windows, supersession chains and status-aware retrieval.

Make Markdown documentation searchable: loads it into SQLite or PostgreSQL with keyword search and optional pgvector hybrid semantic search.

PowerPoint automation for AI: slides, shapes, tables, charts, images, notes. Windows only.

Hierarchical agent memory engine with automatic decay, promotion, semantic deduplication and a self-organizing topic tree.

Pre-action gates that prevent coding agents from repeating known mistakes by turning captured feedback and failures into rules enforced via hooks.

Hosted memory that learns and forgets: feedback re-ranks useful memories, recall fades by recency and similar memories consolidate.

MCP memory server for ZenBrain: agent memory for any Model Context Protocol client — store, recall, consolidate, health. Local SQLite file, no account.

MCP server for reading Simplenote notes across macOS, Linux, and Windows

Access RAGStack serverless knowledge bases on AWS: search, chat with AI answers, upload documents and media, scrape websites and analyze metadata.

Standalone Obsidian vault server: hybrid search, notes and files, memory and tasks; run locally or self-host for remote access.

Connect Claude to Clio: 34 tools for matters, custom fields, notes, documents, folders, billing.

Knowledge base for Claude Code with semantic search, feed intelligence, and teams

Persistent semantic and graph-based agent memory in a single self-contained binary with embedded database and models.

Local-first memory with verbatim recall, querying, health checks and context-sensitive orientation, using LLM-free retrieval by default.

Semantic knowledge graph for Obsidian with graph, classification and hierarchy modes, local embeddings, semantic bridge discovery and drift detection.

Local macOS servers for Mail, Calendar, Reminders, Messages, Contacts, Notes, Shortcuts, Files, Maps and system tools, unified or standalone.

Inspect, search, create, edit, move, and organize notes in Apple Notes on macOS.

Unified Apple ecosystem MCP server for macOS: Mail, Calendar, Notes, Files, Messages, and more.

Four-tier memory (episodic, semantic, project, procedural) with temporal scoring, contradiction detection, entity tracking and a desktop visualization orb.

Save and query agent memory in a distributed way with Membase.

Expose your Quickchat AI agent as an MCP server, giving AI apps real-time access to its knowledge base and conversational capabilities.

Local agent memory with provenance tracking that detects when sources change, plus session handoffs, decision records, semantic search and a knowledge graph.

Temporal codebase knowledge graph that links test failures to code changes, learns co-edit patterns, predicts regression risk and enforces edit constraints.

Cognitive memory engine with knowledge modules, circadian rhythm awareness, emotional state tracking, hybrid PostgreSQL/Qdrant search and per-user isolation.

Create and update Notion pages and auto-generate mdBooks from structured content.

Persistent memory for coding agents storing architecture decisions, bug root causes and conventions, with full-text search and token-budgeted context assembly.

Local-first memory for AI coding agents on SQLite/FTS5, curated and semantically de-duplicated, with data stored as plain rows you own.

Store and retrieve conversation memories from multiple LLMs in MongoDB, with timestamps and LLM identification.

Self-hosted knowledge backend for agents with hybrid vector and keyword search and container-isolated indexes.

Local-first semantic memory: hybrid search, Markdown storage, MLX or CPU embeddings, contradiction detection, time-travel history and cross-machine git sync.

Access your reMarkable tablet - read documents, browse files, extract text and OCR handwritten notes

Digital identity for AI tools: your bio, career, skills and projects in local YAML profiles, auto-generated from public APIs such as GitHub, Medium and Strava.

Annotate papers in Zotero: highlight key findings with semantic color coding, explain formulas and write structured reading notes.

Knowledge marketplace where agents search, publish and unlock previously solved problems, earning tokens for shared solutions.

Reversibly compress large tool outputs into recoverable handles, expand them on demand and track token and cost savings locally.

Local-first, auditable memory with scoped user/project storage in SQLite or Postgres, read-only recall by default and opt-in reviewed writeback.

Connect to any MediaWiki wiki (Wikipedia, Fandom, corporate wikis) to search, read and edit pages, analyze links, view revision history and convert to Markdown.

Remote Obsidian vault management over SSE: notes, directories, frontmatter, tags, search and link operations, deployable with Docker.

Manage Bitwarden and Vaultwarden vaults via the bw CLI: search, create, edit and organize logins, notes, cards, identities, SSH keys, folders and Sends.
