"Temporal" matching MCP servers:

Provides AI assistants with rich temporal intelligence including timezone conversions, 9 cultural calendars (Hebrew, Islamic, Chinese, etc.), astronomical events, Islamic prayer times, and context-aware activity appropriateness recommendations.

Personal memory MCP server backed by SQLite FTS5 BM25 search with temporal reranking.

Enables LLM agents to query a bi-temporal property graph using verified temporal operators via MCP, with auditable claims and correction-aware time travel.

Memtrace is a persistent memory layer for coding agents, built as a bi‑temporal structural knowledge graph over your codebase (AST‑driven symbols and relationships, plus temporal evolution and cross‑service API topology)

razilian public procurement (PNCP) and Federal Revenue CNPJ data for any MCP client. 18 tools covering bids, contracts, atas de registro de preço, annual procurement plans, CNPJ enrichment, plus temporal aggregation and period comparison. MIT licensed, maintained by Licinexus under Law 14.133/2021.

Persistent knowledge graph MCP server with SQLite backend. Enables graph traversal, fuzzy search, temporal queries, and timestamps for entity management.

Enables exploring Steam store reviews and community discussion threads with server-side filtering, temporal analysis, and metadata context for understanding player sentiment and feedback beyond store page noise.

Provides long-term memory and a temporal knowledge graph for AI agents, enabling persistent memory and reasoning across sessions.

Enables AI assistants to search and access geospatial datasets through STAC (SpatioTemporal Asset Catalog) APIs. Supports querying satellite imagery, weather data, and other geospatial assets with spatial, temporal, and attribute filters.

Provides tools to search, download, and manage satellite imagery from all Copernicus Sentinel missions via the Copernicus Data Space ecosystem. It enables advanced geospatial queries, temporal coverage analysis, and automated data management for Earth observation tasks.

Enables persistent knowledge graph management with entities, observations, relations, temporal queries, and graph traversal via Model Context Protocol.

Provides current time and date information with timezone support and multiple formatting options. Enables AI assistants to answer time-related queries in different timezones with detailed temporal information.

MCP server for temporal state queries and cryptographic audit trails. Query historical entity state at any point in time, generate Merkle proofs of past state, and anchor contract snapshots for immutable provenance.

Enables LLMs to build and explore a cognitive neuroscience-inspired knowledge graph with SQLite, supporting search, graph traversal, temporal sequences, and structured reasoning.

Syncs Obsidian notes into a temporal knowledge graph and exposes 23 MCP tools for AI assistants to read, search, and write to your vault, enabling persistent memory across conversations.

Provides 11 MCP tools for deterministic, local semantic search over your documents, including indexing, retrieval, exact-match facets, temporal truth, semantic diff, and agent-first JSON output. Enables LLMs and agents to search, retrieve, and analyze documents without cloud dependencies or per-query costs.

A bi-temporal, provenance-carrying memory primitive for AI agents. Enables storing facts, recall, revision, and audit trails via MCP with SQLite storage.

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.

Enables AI agents to search code by meaning, explore codebase structure, store and query knowledge with temporal facts, and read source code through a set of MCP tools.

Enables AI agents to retrieve and explore evidence from 3GPP meeting documents through MCP, including temporal knowledge graph queries, document section navigation, and citation-backed answers.
