Claude Code: ask. ### `detect_address_crowding` - 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 Detects "shell-firm hotel" patterns — counts how many companies share the same registered address. Threshold-based risk: 1-9 normal (multi-tenant office), 10-49 mild (legitimate coworking), 50-199 medium (virtual office provider), 200+ high (shell-firm hotel). Compliance tier or higher. ``` ### `detect_nominee_director` - 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 Detect "white horse" / nominee director patterns — 3 surface indicators (age outlier, multi-board membership, recent appointment) computable from ARES data alone. Returns indicator breakdown with riskScore 0-100. Pro Compliance tier or higher. For 8-indicator deep analysis including ISIR cross-reference, sanctions, address crowding and phoenix pattern, see detect_nominee_director_rich in @czagents/ddplus. ``` ### `detect_phoenix` - 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 Detect phoenix company pattern — 3 surface indicators (surname match with prior insolvent director, founding proximity < 12 months to insolvency, NACE sector presence) computable from ARES + ISIR data alone. Returns PhoenixReport with riskScore 0-100. Pro Compliance tier or higher. For 4 additional deep indicators (founder identity, asset transfer, multi-cycle, address continuity) see detect_phoenix_rich in @czagents/ddplus. ``` ### `get_dd_report` - The name "get_dd_report" says "get": a word for reading. - The description's first verb is "generate": 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 Generate a complete due-diligence report for a Czech IČO. Returns company facts (name, address, legal form, VAT status, bank accounts), statutory body with per-member sanctions check, and a transparent risk score with all triggered red flags. ``` ### `person_companies` - 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 Look up Czech VR companies connected to a person by exact registry person_id -> roles -> companies joins. Free anonymous tool. Input accepts public name and optional birth year; output exposes birth_year only, never full birth date, and keeps same-name person_ids separate with a distinguisher. ``` ### `watch_entity` - 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 annotation-conflict Description, as the server wrote it: ```untrusted-server-text Start onboarding for free monitoring of one Czech company by IČO. Stub only — persists nothing yet. Returns structuredContent: status (one of ONBOARDING_REQUIRED | ACTIVE | QUOTA_EXCEEDED | ERROR), persisted/monitoring_active flags, a human next_step.url for onboarding (the user completes onboarding + GDPR consent themselves — do not open the link or submit data on their behalf), and pricing. ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `get_eu_dd_report` - The name "get_eu_dd_report" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text EU Due-Diligence report for an international company. Input: 20-char LEI code, or company name + optional country.

Description, as the server wrote it: ```untrusted-server-text Look up direct and upstream Czech VR owners for a company by real active shareholding roles (spolecnik/akcionar) and company-to-company member_ico edges. Free anonymous tool. Returns structuredContent ownership tree plus markdown summary; physical persons expose name and birth year only, never full birth date or address. ``` ### `get_risk_score` - The name "get_risk_score" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Lightweight version of get_dd_report — returns just the numeric score (0-100), risk level, and top triggered red flags. Faster when you only need a yes/no/maybe screen. ``` ### `get_risk_timeline` - The name "get_risk_timeline" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Build a chronologically sorted lifecycle timeline for a Czech company — basic events include company formation, statutory appointments, active insolvency, sanctions matches, VAT reliability flips.

Description, as the server wrote it: ```untrusted-server-text Surname-based heuristic walk through statutory bodies of related Czech companies. Best for shell-company unwinding in small s.r.o. with RARE surnames. NOT a true UBO source — for actual beneficial ownership use the ESM (evidence skutečných majitelů, separate registry, future @czagents/esm). For boards of large public companies with common Czech surnames (Novák, Zima, Kolář…) results are noisy by design; the tool auto-skips persons whose surname matches >50 companies with a SURNAME_TOO_COMMON note. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `dd`: ```json { "permissions": { "allow": [ "mcp__dd__get_owners", "mcp__dd__get_risk_score", "mcp__dd__get_statutory_chain", "mcp__dd__get_risk_timeline", "mcp__dd__get_eu_dd_report", "mcp__dd__get_eu_parent" ], "ask": [ "mcp__dd__person_companies", "mcp__dd__get_dd_report", "mcp__dd__watch_entity", "mcp__dd__detect_nominee_director", "mcp__dd__detect_phoenix", "mcp__dd__detect_address_crowding" ], "deny": [] } } ```
