Popular MCP Servers

Trust Graduation gate for AI agents: visible approval ceremonies and receipt-backed boundaries for consequential actions.

Provides AI-ready access to US/UK nonprofit data and OSS vulnerability intelligence via MCP, with 10 tools and no API key required.

Policy proxy that governs what AI assistants can reach and do: it refuses forbidden tool calls before the upstream is contacted, with per-user memory and a tamper-evident audit. Stops prompt-injection exfiltration and forbidden data combinations across connectors.

Self-hostable MCP server for WhisperGraph — a graph of 7.39B nodes / 39B edges mapping DNS, BGP, GeoIP, WHOIS, and threat intelligence. Six read-only tools (Cypher query + schema introspection + threat assessment), six resources, eight investigation prompts. stdio and Streamable HTTP transports.

Detect and redact PII, PHI, PCI and secrets — SSNs, credit cards, passports, API keys and cloud credentials — in text and in local files, using the Strac DLP API. Five tools: redact_text, detect_sensitive_data, detect_file, redact_file and detokenize.

Allows developers to query security findings (SAST issues, secrets, patches) using natural language within AI-assisted tools like Claude Desktop, Cursor, and other MCP-compatible environments.

Enables AI agents to verify trust scores, search certified capabilities, compare side-by-side, and submit experience reports through Fidensa's certification authority.

Enables AI assistants to securely manage Bitwarden vault items, folders, attachments, and organization administration through the Model Context Protocol.

Connects MCP-compatible AI agents to the AGLedger API for change control, recording every change with signed, hash-chained records. Provides API pass-through tools and an offline audit verifier.

Enables AI assistants to create and manage Hellō applications with full developer context, supporting app creation, updates, secret generation, and logo management through a single unified tool.

Official reference MCP server for A202, the Verifiable Agreement Protocol for Agent-Led Commerce. Gives an agent the seven capabilities two organisations need to buy and sell directly: issue a mandate, check what an agent may do under it, approve an act needing a person, form an agreement, exchange obligations, verify a record by replay, and read the transaction record back.

Exposes PatrowlIntel vulnerability intelligence (CVEs, EPSS, CISA KEV, public exploits, trending attacks) via MCP tools like search_cves, get_cve, and list_trending_attacks.

Scan any project or website for privacy compliance issues directly in your AI coding tool. Detects tracking tech, cookies, and third-party data collection. Works in Claude Code, Cursor, and Windsurf.

Enables MCP-capable agents to create and invoke OpenServerless endpoints, manage secrets, and configure integrations such as S3, PostgreSQL, Redis, Milvus, and MongoDB.

Connects autonomous AI agents and IDEs to the Delentia Sovereign Edge Network, providing deterministic security gating, structured reasoning, context compression, and swarm coordination tools.

Exposes the Agent Policy Router (APR) as MCP tools, allowing any MCP-compatible AI agent to gate its actions through compliance policies before execution.

Email validation MCP server using MailboxValidator API to determine validity of an email address.

Enables security analysis of code and infrastructure files via MCP, using Symbiotic CLI for scanning vulnerabilities.

Enables AI agents to scan MCP servers and AI packages for vulnerabilities, prompt injection, and supply chain attacks.

Kaspersky OpenTIP Model Context Protocol Server. This server gives access to Kaspersky OpenTIP API to agentic applications.
