Claude Code: deny. ### `audience_start_run` - The name "audience_start_run" says "start": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Start a contact pull run for a built audience. Requires audienceId from the build step and totalContacts from preview. If logged in, the run is charged to the account's YourICP billing-token balance (29 billing tokens per contact, where 100 billing tokens = $1.00) and returns a runId — call audience_download_run immediately after. Call check_billing_balance first if you want to tell the user the cost before spending. If the balance is short, this returns error "mcp_insufficient_tokens" with required, available and shortfall counts — tell the user exactly how many tokens to top up at app.youricp.com and do NOT retry until they have. If it returns "mcp_no_billing_account", the client is not linked to an account yet and only support can fix it — do NOT retry. If not logged in, card payment is required instead (capped at $1,000) — this tool returns a checkoutUrl and sessionId, then call check_payment, then audience_download_run with the runId. ``` ### `submit_lookup` - The name "submit_lookup" says "submit": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Submit a contact enrichment job for one or more email addresses or LinkedIn profile URLs. Provide emails, linkedInUrls, or both. If logged in, the job is charged to the account's YourICP billing-token balance (1 billing token per contact matched, 29 if phone validation runs, where 100 billing tokens = $1.00) and returns a jobId — call check_lookup to retrieve results. check_billing_balance shows what the balance covers. If the balance is short, this returns error "mcp_insufficient_tokens" with required, available and shortfall counts — tell the user exactly how many tokens to top up at app.youricp.com and do NOT retry until they have. If it returns "mcp_no_billing_account", only support can fix it — do NOT retry. If the user is not logged in, card payment is required instead: this tool returns a checkoutUrl and sessionId — present the URL, then call check_payment. Do NOT retry automatically on failure. ``` ## Can't be undone (1) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `check_payment` - The name "check_payment" says "payment": a word that usually means money moves, which cannot be taken back. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Check whether a Stripe checkout session has been paid and execute the next step. Call this after presenting the checkoutUrl to the user. If status is "pending", wait a few seconds and call again. - If called after submit_lookup: once status is "done" call check_lookup with the returned jobId. - If called after audience_start_run: once status is "done" call audience_download_run with the returned runId. ``` ## Changes things (5) Creates or changes something that can be changed back. Claude Code: ask. ### `activate_login` - 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 Activate a login completed in the browser. Call this after signing in at the login page. Automatically retrieves the auth token and activates it for this session — no copy/paste needed. ``` ### `audience_download_run` - The name "audience_download_run" says "run": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Get the download link for a completed audience run. Returns a presigned URL the user can click to download their contact list. RENDERING — MANDATORY, VERBATIM: The response contains a download link already formatted as a markdown link with an angle-bracket destination: [Download ...](). Present it exactly as returned. Keep the angle brackets around the URL, do NOT percent-encode or decode any query parameters, and do NOT drop, reorder, or truncate any parameter — every response-content-* and X-Amz-* param must be preserved byte-for-byte. Do NOT rewrite it into a code block, a bare URL, or an HTML anchor; emit the markdown link as the backend sent it. ``` ### `audience_start` - The name "audience_start" says "start": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Entry point for all audience-building workflows. Always call this first when the user wants to find contacts, build an audience, or get a contact list. This tool decides which options to offer based on the connected client: clients that can render the interactive filter widget (e.g. Claude) are offered both (A) describe their target in free text and (B) pick filters interactively; other clients are offered free text only. Present EXACTLY the options contained in this tool's response and nothing more — in particular, do not offer or mention the interactive filter picker unless the response includes it. Do not call audience_quick_preview, audience_preview, or audience_get_filters without calling this tool first. ``` ### `set_auth_token` - The name "set_auth_token" says "set": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: info credentials-mention, warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Set the user's YourICP auth token for this session. Call this when the user pastes their auth token in the chat. This is an API credential, NOT YourICP billing tokens — billing tokens are the prepaid currency a run spends, and check_billing_balance reads them. Once set, the auth token is used for all API requests and card payment is no longer required. To get an auth token, the user can log in at https://mcp.youricp.com/authorize. ``` ### `set_token` - The name "set_token" says "set": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text DEPRECATED — call set_auth_token instead. Sets the user's YourICP auth token for this session. ``` ## Only reads (5) Looks things up and changes nothing. Claude Code: allow. ### `audience_get_filters` - The name "audience_get_filters" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Fetch all available audience filter categories as an interactive filter picker. Only call this after audience_start has been called and the user chose Option B (interactive filter picker). Do not call this tool to guess or pre-populate filters on behalf of the user. RENDERING — MANDATORY, VERBATIM: The response is usually a complete HTML document. Pass the returned HTML string unchanged to the visualizer/render tool. Do NOT rebuild, restyle, summarize, trim, or hand-author a replacement UI. If the response is plain text instead of an HTML document (this happens on clients that cannot render HTML), simply present that text to the user as-is and let them pick filter values by name — do not look for a visualizer. Render EVERY tab and EVERY chip exactly as received, in the order received, using the exact data-cat and data-val attributes the backend emitted. This includes tabs whose chip list is empty — render the empty tab as-is, do NOT drop it and do NOT invent or backfill chips for it. ALWAYS keep the "Get estimation" button (id="getEstBtn") in the rendered widget. It is the action control the user clicks to run the preview — never remove, hide, rename, or replace it. Do NOT move a chip from the tab/category the backend placed it in. If a value arrives under data-cat="industries", it is rendered and reported under industries — the client must not re-route it to seniority, departments, buying_roles, employee_size, or revenue based on its label. Field placement is the backend's responsibility, not the client's. When the user makes selections, resolve names→keys ONLY via the
