"ANB - Acronym or Organization Lookup" matching MCP servers:

An MCP front-end for AnB. The tool surface is "use-don't-reveal": no tool returns a plaintext secret. Reveal paths require a TTY the server doesn't have, so the no-reveal guarantee is structural, not prompt-based — it holds even against a prompt-injected agent. Runs as a dedicated, narrowly-scoped AnB identity; exec is default-deny (only allowlist rules tagged scope=mcp run); command output

Provides live CVE data from NVD and EPSS without API key, enabling AI assistants to look up CVSS scores, search vulnerabilities, and check product CVEs.

Enables querying aggregated vulnerability records from CIRCL's Vulnerability-Lookup, resolving IDs across multiple feeds such as MITRE CVE, NVD, GitHub Security Advisories, PySec, and vendor CSAF, with tools for lookup, search, and recent records.

An MCP server for vulnerability management that provides tools for automated severity and CWE classification using NLP models. It enables AI agents to query the Vulnerability Lookup API for detailed CVE information and search for security vulnerabilities across various sources.

Least-privilege compiler and MCP gateway for AI agents: run your agent in record-only mode, compile the smallest policy it actually needs from its real tool calls, enforce it at the gateway (deny > approve > allow), and keep a SHA-256 hash-chained audit of every call that verifies offline.

Read-only CLI and stdio MCP server that inventories the MCP servers an agent can reach, compiles a least-privilege policy with a reason for every allow/approve/deny verdict, and emits a delivery the recipient re-verifies in their own browser using a sha256 manifest.

Enables read-only triage of Microsoft Entra ID sign-in and audit logs through fixed tools for sign-in failure analysis, user lookup, directory audits, and daily briefs.

An unofficial, read-only MCP server for Mercury business banking. It holds one read-only API token per organization, so a single AI session can work across several Mercury organizations; Mercury's own connector binds one organization per connection.

Enables MCP-compatible agents to query security checklists, protocols, and framework mappings to safely build and operate AI agents, with tools for checklist runs, protocol lookup, mapping lookup, and threat search.

Polish phone number lookup: who called, spam and scam checks, UKE DNO registry, CERT phishing stats

MCP server that exposes Bitwarden's Public API for organization member and vault group management, enabling inviting members and assigning them to vault groups. Supports stateless, multi-tenant authentication via gateway mode or env-based credentials.

MAC-address (OUI) vendor lookup and router default-login directory for AI agents, backed by ssid.ai. Identify a device manufacturer from its MAC address, detect randomized/private addresses instead of reporting unknown, or fetch a router's default login IP and admin credentials — every field cited to the manufacturer's own documentation

Enables querying and analyzing a legacy, file-based vulnerability registry via MCP tools for CVE lookup, search, vendor navigation, and aggregate statistics.

Provides DNS lookup and email authentication diagnostic tools (SPF, DKIM, DMARC, MX, etc.) for use with MCP-compatible clients. Enables natural language queries to check DNS records and email health.

Enables IP geolocation, proxy detection, bulk IP lookup, and domain WHOIS searches through natural language in MCP-compatible clients.

Enables AI assistants to perform cybersecurity tasks including hash analysis, CVE lookup, HTTP header auditing, WHOIS/OSINT, payload decoding, password strength evaluation, and threat report generation.

An MCP server that exposes a legacy vulnerability database as tools for LLM clients, enabling security analysts to query vulnerabilities using natural language through six specialized tools for vendor lookup, vulnerability search, and risk analysis.

Certification lookup for DeepSeek Harness plugins: an agent-facing interface to the dsh-plugin-certification registry, checking a plugin's five reproducible dimensions (manifest compliance, build hygiene, supply-chain Scorecard, release provenance, sandboxed install smoke) before recommending or installing it.

Enables querying MITRE's Common Weakness Enumeration database for vulnerability information, supporting CWE lookup, search, taxonomy navigation, and relationship mapping through MCP.

An MCP server that brings NIST National Vulnerability Database (NVD) intelligence directly into Claude, enabling CVE lookup, product search, and prioritized risk assessment via natural language.
