"MobX-State-Tree" matching MCP servers:

Enables long-horizon AI agents to replace append-only conversation history with a formal, bounded state tuple, supporting state initialization, step execution with transactional rollback, observation injection, and session inspection.

Bridges Zustand stores over WebSocket, enabling MCP-capable AI to inspect and manipulate live application state.

An MCP server that lets an AI agent drive the iOS Simulator in a loop, enabling tapping, typing, swiping, reading the screen via the accessibility tree, and verifying app state.

Persistent, branch-aware workflow state memory MCP server for AI coding assistants. Tracks tasks, accepted decisions, and active blockers to prevent session context bloat and speed up development.

An MCP server that indexes source code into a local database and provides tools for querying code symbols, dependencies, and tree structure for JavaScript/TypeScript, Java, and Python.

Implements the Tree of Thoughts framework for structured reasoning and decision tree exploration, enabling LLMs to explore multiple reasoning paths, evaluate them, and backtrack.

Deep directory tree visualization tool enabling efficient visualization of complex directory structures with AI-powered analysis capabilities.

Graph-native bounded working memory for coding agents with typed memories, causal retrieval, current-vs-stale state queries, and compact small-model briefs.

Enables querying country, state, and city data through the CountryStateCity API, accessible via natural language.

Exposes your todo-tree task list as MCP tools for reading and managing tasks via MCP-compatible AI clients like Claude Desktop.

A Model Context Protocol (MCP) server that enables structured multi-path investigations using a Tree of Thoughts approach.

Single source of truth and control for agent-operated companies, managing business state with deterministic policy enforcement, seat identity, and hash-chained audit trail.

Enables browsing the Ptitchef recipe category tree and reading its recipes without an API key or account.

Real US & Canada dental price data for AI assistants: average costs by procedure, state and city, insurance acceptance, and cheapest-state lookups — backed by open datasets (CC BY 4.0, permanent DOIs).

50-state professional license verification for AI agents.

Gaia MCP enables AI agents to discover, evaluate, and install trusted skills from the Gaia Skill Tree, providing evidence-backed recommendations and safe workspace integration.

24/7 autonomous monitoring and edge detection for prediction markets (Kalshi & Polymarket). Features causal tree analysis, orderbook depth tracking, cross-venue comparison, and real-time alerts.

Persistent operational state for AI agents. Decisions, plans, priorities, and patterns that survive across sessions. Not conversation logs; structured project state with enforcement.

An MCP server that lets an agent inspect and operate Redis-backed job queues, supporting Asynq and BullMQ backends with per-state counts, job details, and state transitions.

Sandboxed Bash for Agents. Full state capture on every command.
