🔌 MCP Server for AI Agents

Free, no key required. Stateless — no accounts, no data stored.

Tools HQ exposes some of its calculations directly to AI agents over the Model Context Protocol (MCP) — the same math the human-facing tools do, callable by Claude, ChatGPT, or any MCP-speaking client, instead of guessed at from training data. This is the same reasoning behind everything else on this site: coordinating across timezones is something people do together, and that includes the AI agents helping them do it.

Endpoint

https://toolshq.net/api/mcp.php

Streamable HTTP transport (MCP spec 2025-06-18) — a single endpoint, POST only, stateless (no session ID needed). Point an MCP client at this URL directly.

Available tools

• 🕒
  find_meeting_time — the best overlapping hour across participants in different timezones, given each person's working hours. Returns a per-participant local-time breakdown for the best hour, plus a link to the interactive planner pre-filled with the result.
• 🌍
  get_current_time — the current date and time in any IANA timezone, with UTC offset and daylight-saving status.
• 💱
  convert_currency — convert an amount between currencies using Tools HQ's exchange rate table.
• 📝
  analyze_text — word/character/sentence/paragraph counts, reading and speaking time, a real Flesch-Kincaid readability grade, and top keyword density for a piece of text.
• 📚
  format_citation — format a website or book source as a correctly formatted citation in APA, MLA, Chicago, or Harvard style.
• 🎡
  pick_random — pick one or more random entries from a list, with or without replacement.
• 👥
  random_teams — split a list of names into random, optionally balanced teams or groups.
• 🔍
  diff_text — a line-by-line LCS diff between two pieces of text, showing what was added, removed, or changed.
• 📲
  generate_qr_link — build a QR code (URL/text, WiFi, contact card, email, SMS, or phone) and get back a link that opens it already filled in and rendered — QR encoding runs client-side, so this returns a working link rather than raw image bytes.
• 📚
  create_study_session — create a synced Pomodoro study-group timer and get back a shareable link; everyone who opens it sees the exact same countdown, no account needed. Persists a session record.
• 🃏
  create_flashcard_set — create a flashcard study set from term/definition pairs and get back a shareable link; anyone can study it with flip cards, Learn mode, or a Test, no account needed. Persists a set record.

Try it directly

Any HTTP client can call it — here's find_meeting_time with curl:

curl -X POST https://toolshq.net/api/mcp.php \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0", "id": 1, "method": "tools/call",
    "params": {
      "name": "find_meeting_time",
      "arguments": {
        "participants": [
          { "name": "Alice", "timezone": "America/New_York" },
          { "name": "Priya", "timezone": "Asia/Kolkata" }
        ]
      }
    }
  }'

Why this exists

Most of the traffic an AI answer engine sends a utility site never becomes a human visit — the agent just answers the question itself. Rather than fight that, this MCP server leans into it: an agent gets the real, correct calculation (not a guess), and every tool result carries a link back to the interactive page here, so the human on the other end of the conversation still has somewhere real to click through to.

This server is new. If something doesn't behave the way the spec says it should, let us know.
