"XState" matching MCP servers:

Enables queries about US commercial and federal-programme real estate debt, loan maturities, subsidy expiries, and Massachusetts property parcel ownership, assessed values, and recorded sales through MCP tools, with eight free unauthenticated tools and one paid debt-maturity schedule tool.

Connects to Korea's MOLIT real estate API to provide 14+ tools for live transaction data and financial scenarios like buy now, buy later, or invest only based on income and savings.

Real Estate Listing - MCP server providing AI-powered tools and automation by MEOK AI Labs

Enables AI assistants to access Washington State Legislature data for bill tracking, committee meetings, legislator lookup, and legislative document retrieval via conversational interfaces.

An MCP-native state sidecar that externalises workflow state for distributed agent deployments.

Provides US real estate data including housing stats, demographics, nearby amenities, area comparisons, cost-of-living analysis, and neighborhood search via free public APIs without any API keys.

Provides state and log management tools designed for long-lived AI agents that may be interrupted and resumed. It enables tracking agent progress and maintaining an append-only event history to ensure continuity across multiple sessions.

MCP server for querying the San Diego Municipal Code, bulletins, permits, parcels, and zoning data with citations and freshness guarantees.

Enables simulation of multi-qubit quantum circuits using complex state vectors, including unitary gates, entanglement, Born-rule measurement sampling, state fidelity, and probability distributions via MCP.

Enables MCP-compatible agents to arbitrate typed state-action schemas, dispatch routine actions deterministically, and apply pre-escalation filters that reduce unnecessary frontier LLM calls. It supports low-latency, schema-enforced routing with safety guardrails and local-first memory retention.

A stateless MCP server for AI film and video production that tracks project state, shot status, and updates, enabling consistent characters and continuity across generative video tools.

Enables persistent storage and retrieval of Tree of Thought search states in PostgreSQL, allowing the travel agent to maintain reasoning context across multi-turn itinerary optimization.

Enables AI agents to persist and restore checkpoint state, supporting crash recovery and replay for LangGraph-based workflows.

Enables agents to construct SHA-256 Merkle trees, generate and verify state inclusion proofs, validate JWT HMAC signatures, perform Schnorr zero-knowledge proofs, and enforce nonce replay protection for immutable state attestation.

MCP server for querying Israeli government real estate data, enabling property deal searches, market trend analysis, and address retrieval.

Enables read-only querying of live brokerage state across Alpaca and Kraken, including account balances, positions, order history, and combined exposure summaries.

Analyzes real estate locations using Kakao Local API, providing insights on education, transportation, convenience, nature, and future value.

Enables agents to access local physiological context—Libre glucose, heart-rate, and watch history—with provenance and freshness metadata, so they can recognize when a user seems unusually off.

Enables AI agents to commit stateful workflow checkpoints by calculating state hashes and rollback points through the Model Context Protocol. It provides deterministic, dependency-free checkpoint management for autonomous agent execution.

Enables users to simulate multi-qubit quantum circuits through an MCP interface, including unitary gates, entanglement, Born-rule measurement sampling, fidelity/probability calculations, and Grover amplitude amplification. Integrates with Claude Desktop, Cursor, and Windsurf via JSON-RPC stdio.
