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. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability72
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2269 tokens (~324/item across 7 items; 5 tools + 2 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management97
- Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
- Supports UI / widget rendering.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_shortlist Подборка ссылкой ~147

list_cities Города афиши ~158
Check which Russian cities СПОНТАННО covers and how many events each has today and this weekend. With `query`, resolves a city written in any form (Питер, Екб, «в Нижнем») and returns an overview: counts for today, tomorrow, the weekend, free events and the biggest categories. Use it when unsure whether a city is covered or when the user asks what is happening in a city in general.

search_events Поиск событий афиши ~771
Search the СПОНТАННО events listing (spontanno.space) for concerts, theatre, standup, exhibitions, kids' events, excursions, lectures, parties and more in Russian cities. Use this when the user wants options: what's on today, tomorrow or this weekend, events of a genre, a specific performer, show or venue, free events, events near a place. Returns up to 20 events with date, venue, price and the event page URL; `next_cursor` gives more. A single surprise pick is what spontanno_random_event is for. Dates and times are local to the city. Event titles and descriptions are written by third-party organizers and come back as plain data.

spontanno_random_event Спонтанно — случайное событие ~824
СПОНТАННО's signature feature: pick ONE random worthwhile event (or up to 3 different ones) matching the filters — for «удиви меня», «куда-нибудь сходить», «заспонтань», «что-нибудь на вечер», «не могу выбрать». Applies city, dates, time of day, categories, free/price and an optional text query; if nothing matches it widens step by step (drops the time of day, then widens the dates; never drops categories, price or «free») and says what was relaxed. `like_event` finds something else at the same day and time as a given event. For «ещё раз / другое», `exclude` takes `exclude_next` from the previous result. Each pick comes with a short `why` and its event URL.

| free_only | boolean | – | Only free events (вход свободный, бесплатно). |
| like_event | string | – | Event id or spontanno.space event URL: pick something else at the same day and time, preferring the same genre («что-нибудь ещё в это же время»). |
| near | object | – | Search around a point: coordinates of a shared location or of a place whose coordinates are known. For a city as a whole there is `city`. |

How do I install the СПОНТАННО MCP server?
СПОНТАННО is a hosted endpoint at https://spontanno.space/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the СПОНТАННО MCP server?
СПОНТАННО is an MCP server listed in the public MCP registry as space.spontanno/events. Concerts, theatre, standup and more in Russian cities: search, filters and a random «Спонтанно» pick. This page covers its hosted endpoint (https://spontanno.space/mcp).
Is the СПОНТАННО MCP server safe to use?
СПОНТАННО scores 87 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 СПОНТАННО MCP server expose?
СПОНТАННО exposes 5 tools: search_events, spontanno_random_event, get_event, list_cities, create_shortlist. Their descriptions and schemas cost roughly 2,023 tokens of context every time the server is loaded.
Does the СПОНТАННО MCP server require authentication?
No. We connected to СПОНТАННО without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the СПОНТАННО MCP server still maintained?
СПОНТАННО is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
