## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 81/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - The endpoint enforces authorisation, advertised via RFC 9728 protected-resource metadata.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 401, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism.
- **Transport & Reachability**: 0/100
  - Transport blocked by authentication: the endpoint requires auth we don't have to verify streamable-http.
- **Schema Quality & AI Usability**: 0/100
  - Schema blocked by authentication: the endpoint requires auth we don't have to read it.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Tool Safety**: 0/100
  - Tool safety blocked by authentication: the endpoint requires auth we don't have to read its tools.
- **Capabilities**: 0/100
  - Capabilities blocked by authentication: the endpoint requires auth we don't have to read them.

**Unverified: 6 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## MCP tools (7)

### `start_round` (~659 tokens)

Start Show & Tell

Start or resume today's Show & Tell round. Show & Tell is a daily game you play with the user: they get a secret word you're not allowed to know, they send you photos of the real world, and you guess the word from the photos. Everyone gets the same word each day. Use this when the user wants to play or asks about today's word. The result has the score so far and how the user sees their word: on the Show & Tell card in apps that show it, or through a private link for the user. Only the user opens that link: it reveals the word, and opening it yourself voids the round. You start without the word's category; the user can spend a hint to reveal it. Leave player empty for a first-time player, then pass the returned code on every later call, including in new chats, so the streak carries over. With mode "go" it starts or resumes today's Get Out & Go instead: five words hiding outside, one at each star (1 to 5), open from 6 a.m. to 9 p.m. in the user's time zone. The user sees the five words on the card or a private /g/ link, never you. With mode "courses" it starts or resumes a Courses run instead: the result has a private /r/ link where the user checks in at a real place with their location; five words written for that place then start with a clock. With a challenge code it joins that friends challenge instead, or picks the user's round in it back up: the user says "Play Show & Tell challenge K7QFX". Pass name, the first name their friends know them by, for the board.

Input parameters:

- `ai_name` (string): The name the user calls you, e.g. "Boo" or "Claude". Shown in the share grid.
- `challenge` (string): A friends challenge code, like "K7QFX", when this call is for that challenge instead of the daily word.
- `mode` (string): "go" for Get Out & Go: five words hiding outside, one at each star. "courses" for Courses: a run at a real place, five words written for it, on a clock. Leave it out for the daily word.
- `name` (string): The first name the user's friends know them by, shown on challenge boards. Ask once if you don't know it.
- `platform` (string): The assistant product you run in: "Claude", "ChatGPT", "Muse", "Grok", "Gemini", "Hermes", "Instinct", or another name. It decides the player's team.
- `player` (string): The player code from start_round, e.g. "brave-otter-4821". The same code in every chat keeps the streak going.
- `timezone` (string): The user's IANA timezone, e.g. "America/Los_Angeles". Always send it when you know it: the day changes at the user's local midnight, and Get Out & Go runs from 6 a.m. to 9 p.m. on their clock. Ask fo…

### `submit_guess` (~398 tokens)

Submit a Show & Tell guess

Lock in exactly one single-word guess for the user's newest photo, or for the hint they just spent, based on all of today's photos together. First describe the photo to the user in one sentence (after a hint, say what it changes). One guess per new photo or hint: otherwise the next guess waits for the next photo. Writing that's already in the world is fine, but the guess can't be a word written in the photo. When writing was made for the game, a screen stands in for the real thing, the user types a hint, or your guess is written in the photo, use call_foul instead. Returns how close the guess is: cold, warm, hot, burning, or correct. In Get Out & Go, pass star: which of the five words the photo is for. Use every photo of that word so far. In a friends challenge, pass its challenge code.

Input parameters:

- `challenge` (string): A friends challenge code, like "K7QFX", when this call is for that challenge instead of the daily word.
- `guess` (string, required): One word. Up to three words only for a fixed phrase.
- `mode` (string): Which star game this photo is for, when the user has both Get Out & Go and a course in play: "go" or "courses". Leave it out to use the one they played last.
- `player` (string, required): The player code from start_round, e.g. "brave-otter-4821". The same code in every chat keeps the streak going.
- `read` (string): One sentence on what you see in the photo (or what the hint changed), kept for the recap.
- `star` (integer): Get Out & Go only: which of the five words this is for, 1 to 5 stars. The user says it, or the card sends "Next photo's for the ★★★ word."

### `call_foul` (~336 tokens)

Call a Show & Tell foul

Call a foul when words, not the picture, would do the telling: writing made for the game (a note, letter tiles), a screen held up to show something, a hint the user types about the word, or your guess is written in the photo. Writing that's already in the world (a label, a logo, a sign) is not a foul unless your guess is written in it. The photo doesn't count and no shot is used. In Get Out & Go, pass the star if you know it. In a friends challenge, pass its challenge code.

Input parameters:

- `challenge` (string): A friends challenge code, like "K7QFX", when this call is for that challenge instead of the daily word.
- `mode` (string): Which star game this photo is for, when the user has both Get Out & Go and a course in play: "go" or "courses". Leave it out to use the one they played last.
- `player` (string, required): The player code from start_round, e.g. "brave-otter-4821". The same code in every chat keeps the streak going.
- `reason` (string, required): "writing": writing made for the game. "screen": a screen stands in for the real thing. "typed_hint": the user typed a hint. "guess_in_photo": your guess is written in the photo.
- `star` (integer): Get Out & Go only: which of the five words this is for, 1 to 5 stars. The user says it, or the card sends "Next photo's for the ★★★ word."

### `use_lifeline` (~340 tokens)

Use a Show & Tell hint

Use this only when the user asks for a hint. Reveals the word's category (after the first photo), its length (after 2 shots), or its first letter (after 4 shots). A hint is a shot of its own: right after it, call submit_guess with your guess, using every photo so far plus the hint; no new photo needed. One hint per shot. Each hint adds a 💡 to the user's share grid, and solving with no hints is the brag. In Get Out & Go, pass the star of the word, and kind "where" (where it's usually found), "letters" or "first_letter"; then guess that word right away with the same star. In a friends challenge, pass its challenge code; the hint shows on the board.

Input parameters:

- `challenge` (string): A friends challenge code, like "K7QFX", when this call is for that challenge instead of the daily word.
- `kind` (string, required)
- `mode` (string): Which star game this photo is for, when the user has both Get Out & Go and a course in play: "go" or "courses". Leave it out to use the one they played last.
- `player` (string, required): The player code from start_round, e.g. "brave-otter-4821". The same code in every chat keeps the streak going.
- `star` (integer): Get Out & Go only: which of the five words this is for, 1 to 5 stars. The user says it, or the card sends "Next photo's for the ★★★ word."

### `get_status` (~327 tokens)

Check Show & Tell status

Check the user's Show & Tell day: whether today's word is played, their streak, whether the streak is at risk, and when the next word unlocks. Use it for check-ins and for daily reminders the user asked you to schedule. With mode "go" it checks Get Out & Go instead: whether today's list is open, how far along they are, and after 9 p.m. their results and the photobomb. With a challenge code it checks that friends challenge: who's in, who's done, and the board once it's out. Without one, the daily status also lists the user's challenges in play.

Input parameters:

- `challenge` (string): A friends challenge code, like "K7QFX", when this call is for that challenge instead of the daily word.
- `mode` (string): "go" for Get Out & Go: five words hiding outside, one at each star. "courses" for Courses: a run at a real place, five words written for it, on a clock. Leave it out for the daily word.
- `player` (string, required): The player code from start_round, e.g. "brave-otter-4821". The same code in every chat keeps the streak going.
- `timezone` (string): The user's IANA timezone, e.g. "America/Los_Angeles". Always send it when you know it: the day changes at the user's local midnight, and Get Out & Go runs from 6 a.m. to 9 p.m. on their clock. Ask fo…

### `start_challenge` (~413 tokens)

Start a Show & Tell challenge

Set up a friends challenge. The user gets a code and an invite to paste into their group chat (texts, WhatsApp, anything), and everyone who joins plays the same secret word by the daily's rules: six shots, a hint is a shot, fewest shots wins, ties go to the fastest. The user plays their own round right away, like a daily round, with the challenge code on every call. Joining stays open for 2 hours (or 1 or 3, their pick) for up to 8 players, and the board stays hidden until everyone's done or 24 hours pass. Pass rematch with a finished challenge's code to play the same group again with a new word.

Input parameters:

- `ai_name` (string): The name the user calls you, e.g. "Boo" or "Claude".
- `join_hours` (integer): How long friends can join: 1, 2 or 3 hours. 2 unless the user says.
- `name` (string): The first name the user's friends know them by, shown on challenge boards. Ask once if you don't know it.
- `platform` (string): The assistant product you run in: "Claude", "ChatGPT", "Muse", "Grok", "Gemini", "Hermes", "Instinct", or another name.
- `player` (string): The player code from start_round, e.g. "brave-otter-4821". The same code in every chat keeps the streak going.
- `rematch` (string): A finished challenge's code, for a rematch with the same group and a new word.
- `timezone` (string): The user's IANA timezone, e.g. "America/Los_Angeles". Always send it when you know it: the day changes at the user's local midnight, and Get Out & Go runs from 6 a.m. to 9 p.m. on their clock. Ask fo…

### `sign_in` (~178 tokens)

Sign in to Show & Tell

Sign the user in to Show & Tell in this app, so every chat here plays as their account, with the same streak in any app they sign in from. Use it when the user asks to sign in, or to keep their streak in every chat. The app may show its own prompt to connect; when they're done, the call carries on. Pass the URL Show & Tell gave for this chat's round, so what they played here comes along.

Input parameters:

- `platform` (string): The assistant product you run in: "Claude", "ChatGPT", "Muse", "Grok", "Gemini", or another name.
- `url` (string): The URL Show & Tell gave in this chat for the user's round, the one only they visit, so what they played here comes along. Pass it as is; don't visit it.

## Common questions

### What is the Show & Tell MCP server?

Show & Tell is an MCP server listed in the public MCP registry as com.playshowandtell/show-and-tell. Daily photo game: you see a secret word, show it in photos, and your AI guesses it. This page covers its hosted endpoint (https://playshowandtell.com/mcp).

### Is the Show & Tell MCP server safe to use?

Show & Tell scores 32 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Show & Tell MCP server expose?

Show & Tell exposes 7 tools: start_round, submit_guess, call_foul, use_lifeline, get_status, and 2 more. Their descriptions and schemas cost roughly 2,651 tokens of context every time the server is loaded.

### Does the Show & Tell MCP server require authentication?

Yes. Show & Tell asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the Show & Tell MCP server still maintained?

Show & Tell is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Show & Tell MCP server?

VerifyMCP ran 4 checks on Show & Tell, covering TLS certificate, Authorization, HSTS header and DNSSEC. 7 items could not be completed, a gap on our side rather than a finding about Show & Tell: HTTPS, Transport, Schema quality, Stability and 3 more. 6 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
