The name "web.robots-sitemap" says "web": it reads web pages, which anyone can write. The description's first sentence says "crawl": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write. - Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it. - Claude Code: ask, because it is tagged outbound. Description, as the server wrote it: ```untrusted-server-text Inspect a domain's robots.txt crawl rules and XML sitemap health, availability, and URL count. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `api-acre`: ```json { "permissions": { "allow": [ "mcp__api-acre__research_lei-entity-search", "mcp__api-acre__document_diff", "mcp__api-acre__data_schema-validate", "mcp__api-acre__developer_openapi-audit", "mcp__api-acre__developer_code-change-review", "mcp__api-acre__developer_structured-diff", "mcp__api-acre__research_us-contract-search", "mcp__api-acre__research_federal-register-search", "mcp__api-acre__research_ofac-entity-search", "mcp__api-acre__research_organization-evidence", "mcp__api-acre__data_worldbank-snapshot", "mcp__api-acre__research_sec-insider-transactions", "mcp__api-acre__research_sec-financial-facts", "mcp__api-acre__research_sec-company-evidence", "mcp__api-acre__research_crossref-work-search", "mcp__api-acre__research_crossref-doi-metadata", "mcp__api-acre__research_wikidata-organization-search", "mcp__api-acre__data_place-geocode", "mcp__api-acre__data_reverse-geocode", "mcp__api-acre__data_current-weather", "mcp__api-acre__data_us-weather-forecast", "mcp__api-acre__crypto_address-inspect", "mcp__api-acre__crypto_base-account-snapshot", "mcp__api-acre__crypto_base-account-status", "mcp__api-acre__crypto_base-event-logs", "mcp__api-acre__crypto_base-network-status", "mcp__api-acre__crypto_base-block-inspect", "mcp__api-acre__crypto_base-contract-inspect", "mcp__api-acre__crypto_base-transaction-inspect", "mcp__api-acre__crypto_calldata-decode", "mcp__api-acre__crypto_typed-data-hash" ], "ask": [ "mcp__api-acre__web_extract", "mcp__api-acre__web_metadata", "mcp__api-acre__web_seo-audit", "mcp__api-acre__web_security-audit", "mcp__api-acre__web_accessibility-audit", "mcp__api-acre__web_performance-profile", "mcp__api-acre__web_links", "mcp__api-acre__web_robots-sitemap", "mcp__api-acre__web_tech-fingerprint", "mcp__api-acre__web_email-auth", "mcp__api-acre__web_domain-intelligence", "mcp__api-acre__web_full-audit", "mcp__api-acre__web_business-due-diligence", "mcp__api-acre__commerce_product-price", "mcp__api-acre__document_extract", "mcp__api-acre__document_tables", "mcp__api-acre__document_redact", "mcp__api-acre__data_profile", "mcp__api-acre__data_clean", "mcp__api-acre__data_convert", "mcp__api-acre__data_json-repair", "mcp__api-acre__data_schema", "mcp__api-acre__data_contract", "mcp__api-acre__data_schemaorg-normalize", "mcp__api-acre__developer_x402-preflight", "mcp__api-acre__developer_dependency-audit", "mcp__api-acre__developer_license-audit", "mcp__api-acre__developer_secret-scan", "mcp__api-acre__developer_code-metrics", "mcp__api-acre__developer_sql-change-review", "mcp__api-acre__research_feed-normalize", "mcp__api-acre__research_news-aggregate", "mcp__api-acre__developer_openapi-test-generate", "mcp__api-acre__data_vin-decode", "mcp__api-acre__research_sec-filing-signals", "mcp__api-acre__data_ecb-fx-reference", "mcp__api-acre__data_us-address-geocode", "mcp__api-acre__data_timezone-convert", "mcp__api-acre__crypto_base-usdc-transfers", "mcp__api-acre__crypto_base-gas-estimate", "mcp__api-acre__crypto_base-contract-read" ], "deny": [ "mcp__api-acre__data_deduplicate" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): -
