Start here: every other tool on this endpoint needs a business, and..." ``` ## Can't be undone (1) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `send_business_inquiry` - The name "send_business_inquiry" says "send": a word for sending, and what is sent cannot be taken back. Description, as the server wrote it: ```untrusted-server-text Send a message to one business. This has a real side effect — it notifies the owner and delivers an email — and is rate-limited both per business and across this directory, so send one considered inquiry rather than a broadcast. ``` ## Changes things (1) Creates or changes something that can be changed back. Claude Code: ask. ### `check_business_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 One business's opening hours, whether it is open right now, and when it next opens. Phase 1 returns published hours, not bookable slots. ``` ## Only reads (5) Looks things up and changes nothing. Claude Code: allow. ### `compare_business_services` - The name "compare_business_services" says "compare": a word for reading. Description, as the server wrote it: ```untrusted-server-text Compare one business's services within a category or keyword, with a price/duration summary. Each row reports `match_type`, so you can tell an exact category hit from an incidental keyword. ``` ### `get_business_agent` - The name "get_business_agent" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The canonical ids and endpoint URLs for one business — its own MCP and A2A endpoints, agent card, llms.txt and public page, under `protocol_urls`. A null URL means that surface is switched off for this business right now: do not construct it yourself, and use one of the non-null surfaces instead. ``` ### `get_business_info` - The name "get_business_info" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Full profile for one business found through search_businesses: identity, locations, contact, policies, images, public documents and the languages it publishes in. ``` ### `get_business_services` - The name "get_business_services" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text One business's service catalogue, with filtering, sorting and pagination. Page with `offset`/`limit` and read `has_more` — the order is stable, so a second page will not repeat or skip a service. ``` ### `search_businesses` - The name "search_businesses" says "search": a word for reading. - Findings: warn tool-shadowing Description, as the server wrote it: ```untrusted-server-text Search the CoreLoop business directory. Start here: every other tool on this endpoint needs a business, and each result carries the `business_id` and `slug` you pass to them as the `business` argument. `business_id` is a PUBLIC, OPAQUE, STABLE routing identifier: it is safe to store and re-use across sessions, it stays the same when a business renames itself or changes its slug, and it carries no sensitive information. Treat it as a token — do not parse it, do not derive meaning from its format, and do not construct one. Pass back exactly the value you were given. A result with `asserts_no_physical_location: true` has stated that it has no premises (consultants, trades, online-only) — it is intentionally absent from city search rather than missing data. `false` means no such statement was made; it does NOT imply premises. Results are returned in your requested language when the business has published a translation: send `?locale=` on the endpoint URL (takes precedence) or an Accept-Language header. Each result reports the language it is written in (`locale`), the business's original language (`content_locale`), and every language it is available in (`available_locales`). `mcp_url`, `a2a_url` and `page_url` — and every URL inside `protocol_urls` — are null when that surface is currently switched off for the business: a null is intentional (do not construct the URL yourself), and the business remains reachable through its non-null surfaces. `data_source: "directory"` marks these rows as the search projection; call get_business_info for the live profile. PAGING: one call returns at most `limit` results. Read `has_more` — a short page is not proof of the end — and pass `next_cursor` back as `cursor` for the next page. The cursor is opaque and bound to the filters and sort it was issued for: change any of them and it is rejected, so start a new search instead. `limit` may change between pages. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `directory`: ```json { "permissions": { "allow": [ "mcp__directory__search_businesses", "mcp__directory__compare_business_services", "mcp__directory__get_business_agent", "mcp__directory__get_business_info", "mcp__directory__get_business_services" ], "ask": [ "mcp__directory__check_business_availability", "mcp__directory__send_business_inquiry" ], "deny": [] } } ```
