"Persistent" matching MCP servers:

A lightweight memory layer for MCP servers that persists user context across LLM sessions with minimal token cost, supporting key-value dedup, multi-tenant namespaces, and optional TTL.

A local-first MCP server providing persistent, searchable knowledge base via SQLite, enabling AI agents to save and recall facts across sessions without cloud dependencies.

Persistent AI memory with SQLite hybrid search (FTS5 + semantic), built-in Qwen3 embedding, and rclone sync across machines.

Creates and maintains a semantic knowledge graph of code that allows maintaining context across sessions with Claude, providing advanced search capabilities without requiring the entire codebase in the context window.

Provides AI agents with a single root terminal tool to a permanent Debian VPS, enabling them to run any Linux command, install software, manage services, and deploy applications that persist across sessions.

Enables AI assistants to list and create Google Calendar events using natural language, with persistent OAuth authentication via Redis.

Persistent semantic memory for your SQL databases. The name is ironic — it remembers everything.

Semantic codebase search + persistent working memory for AI code editors. Local, zero-config, MCP. No API key.

Enables persistent session memory for LLMs by trust-scoring and injecting verified context between conversations.

Enables creating, reading, updating, and deleting sticky notes with persistent text file storage through the MCP protocol.

An MCP server for SSH connections through JumpServer, supporting persistent sessions, multiple bastions, and hot-reload configuration.

Persistent memory for Claude Code — hybrid search, knowledge graph, session lifecycle.

A persistent memory implementation using a local knowledge graph that lets Claude remember information about users across conversations.

Outcome-based persistent memory for AI coding tools.

Local-first persistent memory layer for MCP agents with hybrid search, file ingestion, and GDPR compliance.

MCP server for describing video, image, audio, and text using the Gemini 3.1 Flash Live API with persistent WebSocket sessions.

Persistent memory database for LLM agents with hybrid semantic/keyword search, project scoping, and git commit clustering.

Provides persistent memory for AI assistants, enabling context retention across sessions through hybrid search and memory management tools.

Provides Prolog logic programming integration for Claude via a Docker SWISH container, with persistent notebooks and cognitive architecture support.

Persistent memory database for LLM agents with hybrid semantic and keyword search, project namespacing, and MCP/REST interfaces.
