"Convert Unicode to Characters" matching MCP servers:

Enables reading and updating relationship data (likes, dislikes, important info, feelings, closeness, notes) for characters in a multi-character system, supporting both private and public relations.

Provides OpenCode with adaptive long-term memory by storing preferences, lessons, and usage history locally in SQLite, enabling AI to remember and adapt to users through context-based learning.

Gives an AI game master a persistent memory for tabletop roleplaying games by storing worlds, characters, plots, and scenes. It enables saving, searching, and loading game state (via MCP tools) so the GM doesn't have to recall plot and details only from the context window.

A shared memory MCP server for the Senegalese MOHEBS teaching and learning materials pipeline that ensures AI-generated documents remain consistent in characters, terminology, and concept coverage while varying example domains, operating across grade and subject via Firebase storage.

Turn Obsidian notes into agent-ready context, preview-only plans, and safe repo handoffs.

OmniGlyph is a local-first MCP server that gives AI agents deterministic Unicode, domain-term, security-scan, and output-guardrail checks before reasoning over text or delivering generated output.

MCP server for OpenFic, enabling AI assistants to manage writing projects, volumes, chapters, characters, notes, and worldbooks through OpenFic's public HTTP API. Supports read-only mode by default and opt-in write operations with safety confirmations for deletions.

Enables local, offline querying of birthdays and biographical tags for celebrities, historical figures, and ACG characters, including date-based lists, name/alias search, person details, and upcoming birthdays.

Enables authors to manage characters, chapters, world settings, and plot lines for novel writing, with creative inspiration tools.

A narrative graph engine that enables LLMs to generate, track, and mutate complex fictional worlds while maintaining consistency between factions, characters, and locations. It acts as a specialized RAG framework for storytelling, allowing models to manage thousands of entities without exceeding context limits.

Connects AI assistants to TTRPG campaign data for managing characters, sessions, locations, factions, items, quests, and more.

Exposes 30+ novel-writing tools over stdio or HTTP so external agents such as Claude Code or WorkBuddy can use their own models and API keys to read chapters, write prose, manage characters, foreshadowing, story arcs and worldbuilding, run local semantic search, and launch review sub-agents. Supports one-click enabling with configurable port, token, and approval mode.

Continuity by Ouroboros Apps (https://ouroborosapps.com). Story continuity for fiction writers: a series bible and novel memory that keeps characters, places, timelines, and plot facts consistent across chats. Connect by pasting https://continuitywriter.com/mcp into Claude, Cursor, Grok, or ChatGPT (OAuth). Docs: https://ouroborosapps.com/docs/continuity

Local-first semantic memory server with project indexing for AI assistants. It enables AI assistants to store, retrieve, and search memories and project code using embeddings and vector search.

🧠 High-performance persistent memory system for Model Context Protocol (MCP) powered by libSQL. Features vector search, semantic knowledge storage, and efficient relationship management - perfect for AI agents and knowledge graph applications.

Provides structured access to a temporal knowledge platform for searching historical events and browsing a causal graph of over 2,000 years of history. It enables users to generate rich historical scenes, interact with period-appropriate characters, and run complex temporal simulations.

Helps LLMs maintain coherent timelines, track events, and manage characters across long-form narratives for fiction writing or historical accounts.

Combines bm25, vector and knowledge graphs to create a comprehensive memory solution. https://github.com/lumetra-io/engram-memory-mcp

Turns GitHub repository history into a cited maintainer skill for coding agents, providing tools to collect evidence, query the knowledge graph, and inspect bundles.

A local MCP server that provides persistent, queryable memory for Crusader Kings II tabletop RP sessions, with tools to log and retrieve characters, timeline events, and tomes backed by plain JSON files.
