"Querying Time or Time-Related Information" matching MCP servers:

A Python MCP server for accessing and managing Obsidian vaults, providing tools for reading, writing, searching, and organizing notes across multiple vaults.

Calendar and task management with kernel-level scraping for robust parsing, and integrates with DocMost wiki as source of truth.

Enables AI clients to search, read, and analyze a local SQLite knowledge base built from the full public archives of people you follow, bookmark, or subscribe to, with tools for onboarding, querying, and topic tracking.

Read, search, and write Obsidian vault notes via Team Relay collaborative server. Supports shared folders, real-time sync, and AI agent access.

Cited Q&A and drift detection over your own markdown notes: answers cite exact passages, cited passages are hashed at citation time, and a scheduled verify flags when a source changed under a conclusion already drawn from it. Local-first, zero runtime dependencies (node:sqlite); tools: chamber_ask, chamber_verify, chamber_corpus.

Enables AI assistants to safely read, search, create, append, update, and delete Apple Notes on macOS, with every write or delete requiring human confirmation and operations limited to a single note at a time.

Enables AI assistants to manage goals, tasks, weekly schedules, time tracking, reports, notes, and journal entries on a GoalSlot account through MCP tools.

Persistent sticky notes for Claude Code. You pin a note — a decision, a blocker, a todo — and it survives session resets, /clear, and closing the terminal. Next time you open Claude in that project, the notes that still matter are handed back to it automatically.

An MCP server that gives AI agents durable, temporal memory over local markdown vaults, with tools for searching, asserting facts, querying point-in-time state, and reinforcing useful knowledge.

Exposes Google NotebookLM notebooks as tools for AI assistants, enabling listing, finding, and querying notebooks with grounded answers.

Enables AI agents like Claude Code and Codex to read handwriting and sketches drawn on a tablet in real time via MCP, with local recognition to text/LaTeX, session recording, and export to Markdown/Excalidraw.

An MCP server that enables Claude to interact with Google NotebookLM via browser automation, allowing management of notebooks, adding sources, and querying information.

Provides AI clients with real-time tools for math evaluation, timezone-aware time lookup, live weather retrieval, and persistent note management, all accessible over the Model Context Protocol via stdio.

Enables semantic search over markdown files to find related notes by meaning rather than keywords, and automatically detect duplicate content before creating new notes.

An MCP server that lets Claude read live transcripts and notes from Alt, a real-time lecture/meeting transcription app, while a recording is in progress, pulling only new lines each time.

Enables agents to interact with a Matter read-later library through the public API, supporting search, article and highlight reading, link saving, queue organization, and reading-time summaries.

Enables MCP clients to interact with CalDAV calendars, letting users view schedules, find free time, create and update events, manage tasks and dated notes, and respond to invitations on their own server.

Enables users to access local files, manage persistent notes via CRUD, fetch URLs, inspect system information, and analyze or transform text through MCP tools.

Provides a read-only semantic layer over an Obsidian vault, enabling queries about projects, decisions, tasks, and related notes.

Enables note management (create, read, update, delete, list) through MCP, with advanced features including real-time WebSocket communication, performance optimization, security, and monitoring.
