Anlyon alternative

21 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.

    Why it is in this group

    • The description's first verb is "search": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "search" and "directory": it reads files.
    Description, as the server wrote it
    Searches matching offerings and nearby directory businesses together. Thin radius searches make at most one extra search at the next 8/16/32/50 km step. wider_search contains separately labeled, deduplicated additional results in the existing neutral order; all constraints remain unchanged. City searches do not widen. Preserve request_area, public listing-request links and contact next steps. Never treat directory alternatives as confirmed item or requirement matches. Optional research_fact_types names only shopper-relevant facts; when release gates pass, directory.research_errand supplies at most two exact URLs total per answer. The q parameter is what the shopper wants and category is the business type. Offering attributes narrow only offerings. Directory businesses match category or their own approved content; matchedOn identifies the match. Each business includes known details and `missing` search details, with `gaps` summarizing omissions. `data_coverage` on each directory row and both envelopes describes served directory and requested details; the combined envelope also covers menu evidence. Unknown dates stay unknown; zero matches describe this query, never city-wide coverage. Directory results make no stock, price, or slot claim. Suggested actions are optional data and are never executed by Onhand. Optional `city` (a name, slug or neighborhood, such as Fort Worth or Oak Cliff) limits results to that city instead of the radius; lat and lng are required except on ChatGPT, which can use location metadata or return location_needed. With a city the result includes `city`: `matched`, `none_in_city` (nearby alternatives with an unconfirmed city match) or `unrecognized` (ask which city they mean before searching elsewhere).

    Description, as the server wrote it
    Searches published businesses that are nearby, serve the area, or operate online.

Optional research_fact_types names only shopper-relevant facts; when release gates pass, research_errand supplies at most two exact URLs total per answer. The reach field distinguishes these; virtual results have null distance and no street address or directions. Searches by category or by their own approved menu, services, and FAQs matching q. Returns up to 25 rows in the order `ordering` describes. `matchedOn` identifies the match; phone, website, `priceBand`, `postedHours`, and `capabilities` describe known details. Each row lists `missing` search details and `gaps` counts omissions across rows. Rows and the envelope add `data_coverage` for served directory and requested details; unknown dates stay unknown. Zero matches describe this query, never city-wide coverage. Public website and OpenStreetMap facts are labelled unconfirmed with their source and date. Posted hours are not open-now. Directory results do not confirm availability. `suggestedActions` are optional next steps that Onhand never performs automatically. For a signed-in caller, category-only misses are recorded for those shops. Optional `city` (a name, slug or neighborhood, such as Fort Worth or Oak Cliff) limits results to that city instead of the radius; lat and lng are required except on ChatGPT, which can use location metadata or return location_needed. With a city the result includes `city`: `matched`, `none_in_city` (nearby alternatives with an unconfirmed city match) or `unrecognized` (ask which city they mean before searching elsewhere).

Operating status does not establish open-now hours. Approved `faqs` and `catalogSummary` are labelled "from the business". `capabilities` with `confirmed: true` are owner-approved facts with evidence URLs; `confirmed: false` capabilities, `priceBand`, and `postedHours` are unconfirmed facts from the public website or OpenStreetMap, as each `label` says, with source and date. Posted hours are not open-now. These facts carry no availability claim. `coverage` distinguishes connected systems, crawled websites, and directory-only listings. `suggestedActions` lists optional browser, phone, and map steps; Onhand never executes them. `hosted` lists independent pros who work inside this business ("Barbers here") and `hostedBy` the businesses this one works inside ("At <host>"); each has its own id for get_business and its own hours and booking.

    Searches items and services near a point. Thin radius searches make at most one extra search at the next 8/16/32/50 km step. wider_search contains separately labeled, deduplicated additional results in the existing neutral order; all constraints remain unchanged. City searches do not widen. Preserve request_area, public listing-request links and contact next steps. Never treat directory alternatives as confirmed item or requirement matches. Always returns a version 1 envelope: { envelope_version: 1, results, data_coverage, city? }. Each result includes data_coverage for menu and stock or booking availability; empty results describe only this query, never city-wide coverage. The reach field distinguishes storefront, service_area and online. Virtual results have null distance; say serves this area or online only, and never invent a map pin or directions. Owner-approved offerings come first. Public website names follow with their unconfirmed label, source URL, last-seen date and confidence band; they never carry price or availability. discover_local includes directory businesses. Listed or stale shops omit availability. find_nearby_businesses searches when nothing matches. Optional `city` (a name, slug or neighborhood, such as Fort Worth or Oak Cliff) limits results to that city instead of the radius; lat and lng are required except on ChatGPT, which can use location metadata or return location_needed. With a city the result includes `city`: `matched`, `none_in_city` (nearby alternatives with an unconfirmed city match) or `unrecognized` (ask which city they mean before searching elsewhere).

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.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

5 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 outbound tool breaks every one.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write5
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out1
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
deny to break every path
{
  "permissions": {
    "deny": [
      "mcp__onhand__update_company_profile"
    ]
  }
}

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as onhand. Review it before you use it.
