1password vs Shodan
A side-by-side look at the 1password and Shodan MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose 1password for security work as a local process; choose Shodan for security as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities
1password tools 15
vault_listList the 1Password vaults accessible to the service account (limited to the allow-listed vaults when OP_MCP_ALLOWED_VAULTS / --allowed-vaults is configured). Returns vault IDs, names, descriptions, and types.item_lookupSearch for items within a 1Password vault by title substring. Returns item IDs, titles, categories, and vault IDs.item_deletePermanently delete an item from a 1Password vault. This action cannot be undone.item_getRetrieve a full 1Password item — title, category, tags, notes, and all fields (id, title, type, section). Secret-bearing field values (passwords and other concealed fields, SSH private keys, one-time-password seeds, card numbers) are hidden unless reveal is true; only known non-secret types (text, URL, email, phone, date, menu, card type, address, reference) are shown by default. Accepts a secret reference (op://vault/item/field) or vault ID + item ID. Revealing a secret puts it in the model context/transcript — to USE a secret in a command or API call, prefer op_run with op:// references instead.item_editEdit an existing 1Password item. Update the title, notes (pass an empty string to clear notes), tags, website URL, upsert fields, or remove fields. Only referenced fields are changed; all others are preserved.item_listList all items in a 1Password vault, returning id, title, category, tags, and updatedAt for each. Never returns secret values.item_archiveArchive an item in a 1Password vault. The item is moved to the archive and hidden from regular views, rather than being permanently deleted.note_createCreate a Secure Note item in a 1Password vault, with optional tags and custom fields.password_createCreate a new password/login item in a 1Password vault with optional username, URL, tags, and notes.password_readRetrieve a secret from 1Password using either a secret reference (op://vault/item/field) or vault ID + item ID. Supports field selection and optional value reveal (defaults to metadata-only). Revealing a secret puts it in the model context/transcript — to USE a secret in a command or API call, prefer op_run with op:// references instead.password_updateUpdate (rotate) a password or concealed field on an existing 1Password item. If the target field does not exist, it will be created.password_generateGenerate a cryptographically secure random password with configurable length and character types. Uses rejection sampling for unbiased randomness.- +3 more on the listing page

ip_lookupRetrieve comprehensive information about an IP address, including geolocation, operating system, open ports, running services (product, version, CPE), known vulnerabilities (CVEs), SSL certificates, hostnames, and cloud provider details if available. Returns service banners and HTTP server information when present. Optional history returns historical banners; minify omits banners.shodan_searchSearch Shodan's database of internet-connected devices. Returns detailed information about matching devices including services, vulnerabilities, and geographic distribution. Supports advanced search filters and returns facet statistics (default: by country). Costs 1 query credit when the query uses filters, plus 1 per page beyond the first. Use shodan_count (free) to get totals and facets without results.cve_lookupQuery detailed vulnerability information from Shodan's CVEDB. Returns comprehensive CVE details including CVSS scores (v4/v3/v2), EPSS probability and ranking, KEV status, proposed mitigations, ransomware associations, and affected products (CPEs).dns_lookupResolve domain names to IP addresses using Shodan's DNS service. Supports batch resolution of multiple hostnames in a single query. Returns IP addresses mapped to their corresponding hostnames.reverse_dns_lookupPerform reverse DNS lookups to find hostnames associated with IP addresses. Supports batch lookups of multiple IP addresses in a single query. Returns all known hostnames for each IP address, with clear indication when no hostnames are found.cpe_lookupSearch for Common Platform Enumeration (CPE) entries by product name in Shodan's CVEDB. Supports pagination and can return either full CPE details or just the total count. Useful for identifying specific versions and configurations of software and hardware.cves_by_productSearch for vulnerabilities affecting specific products or CPEs. Supports filtering by KEV status, sorting by EPSS score, date ranges, and pagination. Can search by product name or CPE 2.3 identifier. Returns detailed vulnerability information including severity scores and impact assessments.shodan_countGet the total number of Shodan results for a query, with optional facet breakdowns (e.g. by country, org, port). Free: does not consume query credits. Use search_filters to list valid filters and facets.domain_infoGet subdomains and DNS records for a domain from Shodan. Costs 1 query credit per lookup.api_infoShow the Shodan API plan, remaining query and scan credits, monitored IPs, and usage limits for the configured API key. Free: does not consume credits.search_filtersList the search filters and facets Shodan supports. Use this to build valid shodan_search and shodan_count queries and facets. Free: does not consume credits.
