    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 160 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 173

Showing 100 of 173 tools.

alerts_list

List your alerts or a group's alerts. Requires current group membership.

Discovered
alerts_raise

Record or update a condition under a stable key. No notification is sent. Group administrators may raise shared alerts.

Discovered
alerts_update

Acknowledge, resolve or dismiss an alert. Group administrators may update shared alerts. Resolving a custom alert allows the next occurrence to reopen it.

Discovered
apps_build

Queue a durable app build and immediately return its ID and status URL. Use BuildStatus to retrieve progress and the completed app. Reuse request_key on retries. Builds survive server restarts

Discovered
apps_builds

List your app build jobs and outcomes

Discovered
apps_buildstatus

Read your saved app build status by ID. Poll until complete or failed; the same ID survives restarts.

Discovered
apps_collection

List your saved apps and their source references

Discovered
apps_create

Create an app — a small, self-contained HTML tool hosted here. Takes the HTML; apps_build writes it for you from a description Apps run in a sandbox. Use fetch('/api/v1/<service>/<method>') or mu.service(name, method, args); mu.api does not exist. Direct external fetch is blocked. Inspect real service schemas and data before coding; never invent fields, rankings or claim runtime verification from static checks.

Discovered
apps_edit

Edit an app you own — its name, description, tags, icon, HTML or price. Fields left out keep their value Apps run in a sandbox. Use fetch('/api/v1/<service>/<method>') or mu.service(name, method, args); mu.api does not exist. Direct external fetch is blocked. Inspect real service schemas and data before coding; never invent fields, rankings or claim runtime verification from static checks.

Discovered
apps_embed

Show a saved micro app in the conversation. Embedding preserves access permissions and does not publish the app

Discovered
apps_fork

Fork an app into your own account, to change independently of the original

Discovered
apps_read

Read an app or build status by slug, including source HTML for apps you own

Discovered
apps_search

Find your saved private micro apps by name, description or tag

Discovered
apps_test

Test an app by checking its HTML and checking supported SDK calls; this is not browser execution, so an author finds out what is broken without opening it

Discovered
archive_list

With a kind, the most recent entries of it. Without one, what kinds are archived and how much of each

Discovered
archive_search

Search everything this instance has collected, across news, video, markets and posts at once. Use it when the question crosses a service, or when you do not know which service would hold the answer; news_search is narrower and better when you know it is news

Discovered
blog_create

Publish a post to the caller's blog. For anything meant to be read later by other people — notes, write-ups, announcements. For a private note to yourself, prefer files or memory

Discovered
blog_delete

Delete one of the caller's own blog posts, by id or title. Refuses posts written by anyone else, and refuses an ambiguous title rather than guessing. Irreversible, so confirm with the user first

Discovered
blog_list

Read recent blog posts — titles, snippets and ids

Discovered
blog_read

Read one blog post in full, by id or by title. Use after blog_list has found a candidate and the summary is not enough

Discovered
blog_update

Edit one of the caller's own posts. Fields left out keep their current value

Discovered
bookmarks_add

Save an article, video, blog post or link privately. Re-saving preserves its note

Discovered
bookmarks_annotate

Set or clear a private note on one saved item

Discovered
bookmarks_delete

Remove one of your saved items

Discovered
bookmarks_get

Read one saved item and its private note, with available archived text. Videos have descriptions, not transcripts

Discovered
bookmarks_list

Find your saved reading by text or kind, newest first. Private notes are searched too

Discovered
browser_read

Open a page in a real browser and read it after its JavaScript has run. Use it when web_fetch comes back empty or with only a nav bar, which is what a page that builds itself in the browser looks like to a plain fetch. web_fetch is free and is the right first try; this costs, because it runs a browser

Discovered
browser_shot

Photograph a page and get back a URL for the picture. What it looks like, rather than what it says — a chart, a layout, a page whose content is an image. Ask for full to capture past the first screenful

Discovered
chat_messages

Read the recent conversation in a discussion room

Discovered
chat_rooms

List discussion rooms that currently have activity

Discovered
chat_send

Say something in a discussion room, as the caller. Use chat_rooms to find the room id

Discovered
chat_source

Read one stored message owned by the caller, by id

Discovered

Discovered
contacts_add

Save someone to the address book. Adding a name already there updates it rather than making a second card

contacts_find

Look someone up in the address book by name, part of a name, or address. Use this before sending mail to a person named rather than addressed

Discovered

Discovered
docs_list

List your documents, most recently changed first, with an optional search over titles and bodies. Use this to find an id

Discovered
docs_write

Write a document — a title and a markdown body. Pass an id to replace one you already have. Private unless you set public. For something long enough to re-read; for a short thing to remember, use notes

Discovered
events_create

Schedule a reminder or event at a given time; optionally repeating, and optionally running a prompt through the agent when it fires

Discovered
events_delete

Cancel an event by id

Discovered
events_free

Find when the caller has nothing booked — open slots of a given length, within working hours

Discovered
events_list

List the caller's upcoming events and reminders, each with its id

Discovered
events_read

Read one schedule owned by the caller

Discovered
events_update

Update one of your scheduled events without changing its id. Omitted fields stay unchanged; empty notes, prompts or recurrence clear them

Discovered
files_delete

Delete a file you own

Discovered
files_driveread

Read the caller's connected Google Drive. Read-only; connect in Account first.

Discovered

Store a file and get a URL for it — a report, a CSV, a transcript

Discovered
files_share

Make a file readable by anyone with its URL, or private again

Discovered
flights_airport

Report what is happening at an airport right now: what is on the ground, what is on approach and what is climbing out. Live positions, not the timetable, so it says nothing about scheduled or delayed departures

Discovered
flights_overhead

List the aircraft flying near a location right now, nearest first, with altitude, speed, heading and distance. Live positions broadcast by the aircraft themselves, not a schedule

Discovered
flights_status

Scheduled, estimated and actual flight arrival/departure times from Aviationstack. Requires a configured provider.

Discovered
flights_track

Find where an aircraft is right now by flight number ('BA117'), radio callsign ('BAW117') or registration ('G-ZBKL'). Only sees aeroplanes that are airborne and in range of a receiver — not finding one does not mean the flight was cancelled

Discovered
food_hygiene

Food hygiene ratings for UK businesses, from the Food Standards Agency inspections. Takes a business name, a town or postcode, or a lat/lon to look around

Discovered
food_product

Look up a packaged food by its barcode — name, brand, ingredients, allergens, nutrition per 100g, Nutri-Score and how processed it is

Discovered
food_search

Find packaged foods by name or brand, with the barcode of each so one can then be looked up in full

Discovered

Discovered
groups_list

List your groups and pending invitations

Discovered
groups_read

Read a group you belong to and open its chat

Discovered

Discovered
hazards_alerts

Current disasters worldwide from GDACS — cyclones, floods, volcanoes, wildfires and earthquakes — with an alert level of green, orange or red. Pass lat/lon to ask about somewhere in particular

Discovered
hazards_floods

Flood warnings and alerts in force in England, most severe first, from the Environment Agency. The one hazard here that is a forecast rather than a record — a warning says flooding is expected, which is something you can act on. Optionally near a point. England only, and the answer says so

Discovered
hazards_quakes

Recent earthquakes worldwide from the USGS, with magnitude, place and how long ago. Pass lat/lon to ask about somewhere in particular, min for a magnitude floor, and period for hour, day, week or month

Discovered
images_daily

images_delete

Delete an image you own

Discovered
images_generate

Generate an image from a text prompt and return its URL

islam_read

Read the full Islamic source passage from an islam_search result, with its source and reference. Preserve distinctions between original text, translation and commentary.

Discovered
islam_references

Search Quran, hadith and names of Allah by meaning through Reminder. Returns source passages and original metadata, never a generated answer. Use full source context before interpretation; missing authenticity metadata is not a grading.

Discovered
islam_saying

Read Reminder’s Sahih al-Bukhari collection, optionally selecting a book. This is not a lookup by hadith number.

Discovered
islam_search

Search Aslam.org's Quran, hadith, names of Allah, Seerah, Ghazali, IslamQA, adhkar and Riyad us-Salihin. Returns reference excerpts, not generated answers. Distinguish Quran and hadith from biography and scholarly interpretation; cite the source.

Read the caller's connected Gmail. Read-only; connect in Account first.

Discovered
mail_gmailsearch

Search the caller's connected Gmail. Read-only; connect in Account first.

Discovered
mail_inbox

List the account's most recent messages — read my mail, check my inbox

Discovered
mail_info

How to reach the caller here: the handle, the email address if this instance has a mail domain, and whether mail from outside can arrive at all. Pass a tag for a separate one (you+tag) — give that out, then read only its messages with mail_inbox(tag)

Discovered
mail_markread

Mark specified inbox message IDs, or explicitly all current inbox messages, as read. Changes read status only; does not read, summarize or triage the content.

Discovered
mail_read

Read your correspondence by id in bounded body-character pages, including attachment names. Follow the returned next offset for the rest. Omitting id retains the legacy inbox summary

Discovered
mail_search

Search the account's mail and return matching messages

Discovered
mail_send

Write to somebody, as you. A username reaches them on this instance and is free; a full email address leaves over SMTP under this instance's domain, so a reply comes back to your inbox, and is charged. Resolve a name with contacts_find first. Mail that leaves needs MAIL_DOMAIN configured on the instance

Discovered
mail_source

Read one stored message owned by the caller, by id

Discovered
mail_sources

List stored message ids owned by the caller

Discovered
maps_area

Every tile covering a bounding box at a zoom level, as URLs, row by row from the north-west, and how many are already held. What to ask for when you want the map around a place rather than one numbered tile

Discovered
maps_tile

The URL for one map tile, by zoom, column and row. Styles: road, outdoor (rights of way and contours), light (a quiet basemap to draw on). Free. Britain only

Discovered
markets_convert

Convert an amount from one currency to another — 250 GBP in JPY. Uses European Central Bank reference rates, and takes a past date back to 1999. Crypto converts at the live price through the dollar
