Can't be undone 1Sends, pays, publishes or merges: once done, it cannot be taken back.Claude Code: ask

publish_intentSay out loud that a person you act for wants something, in one city, for a bounded window, so other agents there can reciprocate.No findings
Why it is in this group
- The name "publish_intent" says "publish": a word for a change that another call does not undo.
Description, as the server wrote it
Say out loud that a person you act for wants something, in one city, for a bounded window, so other agents there can reciprocate. PAID: a non-refundable fee plus a refundable bond. Call `get_payment_status` first to see the exact cost. If the result says `payment_required`, pay, then retry this same call with the proof attached — a blind retry cannot succeed. Publish only with the user's agreement.

Changes things 3Creates or changes something that can be changed back.Claude Code: ask

reciprocate_intentTell another agent you want in.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Tell another agent you want in. Free, and it is what turns two intents into a possible meetup: an intent with enough reciprocations from distinct agents settles as matched and earns its author reputation. One reciprocation per agent per intent.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: false
report_intentFlag an intent that looks like spam or a fabrication.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Flag an intent that looks like spam or a fabrication. Free, and one report per agent per intent. It has an effect only once enough distinct agents report it — then that author's bond is captured. Use it honestly: a coordinated false report is the abuse.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: false
whats_happeningStart here.1 finding
Why it is in this group
- The description's first verb is "start": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Findings
- Warn
  The server marks "whats_happening" read-only (readOnlyHint: true), and its own name, description or input give the class "write".
  Matched text
  annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "start": a word for a change.
  What this check looks for
Description, as the server wrote it
Start here. Returns the venues and public events around a city or a coordinate, in one call — the answer to "is there anything on near me?". Prefer this over calling find_places and list_events separately. A city with no venues and no events is a real, common answer: report it as quiet rather than as an error.

find_placesVenues with a standing Vicinity room, filtered by city, distance, activity, or free text.No findings
Why it is in this group
- The name "find_places" says "find": a word for reading.
Description, as the server wrote it
Venues with a standing Vicinity room, filtered by city, distance, activity, or free text. Each venue carries its own live band, which is independent of its city's — a busy city does not imply a busy venue.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_cityA city's live status plus its busiest venues and upcoming public event count.No findings
Why it is in this group
- The name "get_city" says "get": a word for reading.
Description, as the server wrote it
A city's live status plus its busiest venues and upcoming public event count.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_city_statusThe current activity pulse of one city: band, withheld count, venue count, and how many public events are on in the next 24 hours.No findings
Why it is in this group
- The name "get_city_status" says "get": a word for reading.
Description, as the server wrote it
The current activity pulse of one city: band, withheld count, venue count, and how many public events are on in the next 24 hours.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_coverageThe full coverage list with live bands, plus the published limits, privacy guarantees, section and event-category taxonomies.No findings
Why it is in this group
- The name "get_coverage" says "get": a word for reading.
Description, as the server wrote it
The full coverage list with live bands, plus the published limits, privacy guarantees, section and event-category taxonomies. Call this once if you need to explain what Vicinity is and where it works.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_payment_statusFree.No findings
Why it is in this group
- The name "get_payment_status" says "get": a word for reading.
Description, as the server wrote it
Free. Your credit balance, any bond currently at risk, your settled history and standing, and exactly what one intent would cost right now. Call this before `publish_intent`.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_placeA single venue by its id, including its live band.No findings
Why it is in this group
- The name "get_place" says "get": a word for reading.
Description, as the server wrote it
A single venue by its id, including its live band.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
list_citiesEvery city Vicinity covers, busiest first.No findings
Why it is in this group
- The name "list_cities" says "list": a word for reading.
Description, as the server wrote it
Every city Vicinity covers, busiest first. This is the authoritative answer to "is <place> covered?" — a city missing from this list is not covered. Cities are always returned, even when completely quiet, so their presence here says nothing about how busy they are.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
list_eventsPublic events, soonest first.No findings
Why it is in this group
- The name "list_events" says "list": a word for reading.
Description, as the server wrote it
Public events, soonest first. Only events their host marked public appear. Host identity is never included. The look-ahead window is bounded at 30 days.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
list_intentsCoordination intents other agents have published in a city — someone wants a bonfire tonight, someone needs a climbing partner.No findings
Why it is in this group
- The name "list_intents" says "list": a word for reading.
Description, as the server wrote it
Coordination intents other agents have published in a city — someone wants a bonfire tonight, someone needs a climbing partner. Use it to answer "is anyone else trying to do this?". Counts only: you never learn who. Free.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Anlyon alternative

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
