Description, as the server wrote it: ```untrusted-server-text Reports whether a confirmed booking, order, or quote handoff completed, failed (dead link or broken form), or was abandoned. Once per action, within 72 hours, for this signed-in shopper only. A failure queues a re-check of the link. A report is not a receipt: it never completes a booking or backs a review. ``` ### `submit_verified_review` - The name "submit_verified_review" says "submit": a word for a change. - The description's first verb is "publish": a word for a change that another call does not undo. - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Returns only answers from the business's approved FAQs (labelled "from the business") and owner-approved website facts with evidence URLs. Returns `answered: false` when the business has not answered this question; the response includes a note that the business should be asked directly. Answers are never composed or inferred. ``` ### `check_availability` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it: ```untrusted-server-text Confirms a prepared quote handoff once using the intent from prepare_quote_request and returns the revalidated provider URL.

Description, as the server wrote it: ```untrusted-server-text Prepare a reservation or appointment.

Description, as the server wrote it: ```untrusted-server-text Submit up to five public business facts with a signed research receipt. Ask the shopper before calling. No personal information, availability, item prices, HTML or instructions. Evidence enters quarantine for verification; receipt grants no publication authority. Collection is off until release gates are satisfied. ``` ### `request_area` - The name "request_area" says "request": a word for a change. Description, as the server wrote it: ```untrusted-server-text Records that a shopper wants a shop category near a place, so Onhand can see where to add listings. Anonymous: send the category and, if known, lat and lng (kept only as a coarse area, never stored exactly). No email is collected and there is no follow-up. Ask the shopper before calling. One request per caller per day. `status` is `accepted` (recorded) or `queued` (enough requests that the area is waiting for review); neither promises coverage or a date. Say what `message` says and never tell the shopper an area is not covered. ``` ### `select_subject` - The name "select_subject" says "select": a word for a change.

Description, as the server wrote it: ```untrusted-server-text Stage a change to the merchant's own listing: name, website, phone, or categories. Changes nothing on its own: returns a one-time intent and a sentence describing exactly what confirming it would do. Requires company:write and takes no company identifier from the caller. ``` ### `update_hours` - The name "update_hours" says "update": a word for a change. Description, as the server wrote it: ```untrusted-server-text Stage new opening hours for one of the merchant's own locations.

Requires company:write. ``` ## Only reads (15) Looks things up and changes nothing. Claude Code: allow. ### `discover_local` - The description's first verb is "search": a word for reading. - Tag private-data: The description's first sentence says "search" and "directory": it reads files. Description, as the server wrote it: ```untrusted-server-text 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). ``` ### `find_business` - The name "find_business" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Finds a business by name, optionally narrowed by town or street. Returns ids for get_business. Useful when a shopper names a shop rather than a place. Rows and the envelope include `data_coverage` for directory identity only. Unknown evidence dates stay unknown; an empty name match says nothing about city-wide coverage. ``` ### `find_nearby_businesses` - The name "find_nearby_businesses" says "find": a word for reading. - Findings: info long-description Description, as the server wrote it: ```untrusted-server-text Searches published businesses that are nearby, serve the area, or operate online. 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, 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). ``` ### `get_action_status` - The name "get_action_status" says "get": a word for reading.

A requested handoff is not a completed provider booking. ``` ### `get_billing_link` - The name "get_billing_link" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Where the merchant manages their subscription. It does NOT open Stripe's portal: that session is minted on the API when they ask for it there. Requires billing:write. ``` ### `get_business` - The name "get_business" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Returns a published business profile, hours, area, and rating. `directoryEvidence` and `directoryConflicts` give per-field evidence and disagreements; missing facts stay unknown. 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 "); each has its own id for get_business and its own hours and booking. ``` ### `get_company` - The name "get_company" says "get": a word for reading.

Requires company:read and takes no company identifier from the caller. ``` ### `get_connection_link` - The name "get_connection_link" says "get": a word for reading. - Findings: info credentials-mention Description, as the server wrote it: ```untrusted-server-text Where the merchant connects, reconnects, maps the locations of, or disconnects a point-of-sale or catalog source, plus a sentence saying what happens there. It does NOT perform the action: consent, location confirmation and revocation need credentials this service does not hold, and they happen in the dashboard. Requires connections:write. ``` ### `get_open_slots` - The name "get_open_slots" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Next open appointment windows at one business, soonest first. Slots are offers, not holds: nothing is reserved and no payment is taken. Slots whose sync has gone stale, or that have already started, are omitted rather than guessed. ``` ### `get_subscription` - The name "get_subscription" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text What the merchant's organization is paying for. Requires billing:read. Never returns Stripe identifiers. ``` ### `list_connections` - The name "list_connections" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The merchant's connected point-of-sale and catalog sources, and whether each is syncing. Requires connections:read.

Returns no shopper identity, booking identifier or provider reference. ``` ### `search_local_offerings` - The name "search_local_offerings" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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). ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `onhand`: ```json { "permissions": { "allow": [ "mcp__onhand__discover_local", "mcp__onhand__search_local_offerings", "mcp__onhand__get_open_slots", "mcp__onhand__get_company", "mcp__onhand__list_locations", "mcp__onhand__list_connections", "mcp__onhand__get_subscription", "mcp__onhand__get_connection_link", "mcp__onhand__get_billing_link", "mcp__onhand__list_subjects", "mcp__onhand__get_action_status", "mcp__onhand__list_verified_reviews", "mcp__onhand__find_business", "mcp__onhand__find_nearby_businesses", "mcp__onhand__get_business" ], "ask": [ "mcp__onhand__update_company_profile", "mcp__onhand__update_hours", "mcp__onhand__select_subject", "mcp__onhand__setup_account", "mcp__onhand__start_business_claim", "mcp__onhand__prepare_booking", "mcp__onhand__prepare_booking_cancellation", "mcp__onhand__prepare_checkout", "mcp__onhand__prepare_quote_request", "mcp__onhand__confirm_quote_handoff", "mcp__onhand__report_business_facts", "mcp__onhand__request_area", "mcp__onhand__ask_business", "mcp__onhand__check_availability" ], "deny": [ "mcp__onhand__confirm_update_company_profile", "mcp__onhand__confirm_update_hours", "mcp__onhand__confirm_booking", "mcp__onhand__confirm_booking_cancellation", "mcp__onhand__confirm_checkout_handoff", "mcp__onhand__submit_verified_review", "mcp__onhand__report_action_outcome" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__onhand__discover_local`: private-data - `mcp__onhand__update_company_profile`: outbound - `mcp__onhand__confirm_booking`: untrusted-input - `mcp__onhand__confirm_booking_cancellation`: untrusted-input - `mcp__onhand__confirm_checkout_handoff`: untrusted-input - `mcp__onhand__submit_verified_review`: untrusted-input - `mcp__onhand__list_verified_reviews`: untrusted-input
