"General inquiry or casual greeting" matching MCP servers:

PII sanitization layer for autonomous AI agent pipelines. Detects and redacts emails, phone numbers, national IDs, private keys, and financial data before text reaches LLMs. Supports EN, ES (LATAM), PT (BR/PT), DE, JA.

Transparent Go proxy that intercepts, signs, rate-limits, redacts, and audits all MCP JSON-RPC tool calls without modifying client or server. Stores to JSONL or SQLite with HMAC-SHA256 signatures.

Enables AI agents to perform general-purpose open-source intelligence lookups across domains, infrastructure, identity, social media, and threat/breach sources through a unified MCP interface, with most tools free and no API keys required.

MCP server for Quackr, enabling virtual phone number management including balance checking, pricing, inventory, purchasing numbers, and reading SMS via Claude or any MCP-compatible client.

Scans generated JavaScript/TypeScript code to detect AI-hallucinated or suspicious npm package imports before installation, providing a verdict of CLEAN, REVIEW, or BLOCK.

Enables secure delivery of Bitwarden Secrets Manager secrets to approved local files without exposing secret values to the MCP client or model. It provides metadata-only secret discovery and atomic file writes for single secrets or raw env files.

Enables autonomous AI agents to operate safely by intercepting risky tool calls, evaluating them against policy, and suspending them for human approval via Slack, Telegram, or a web dashboard.

A prompt-validation service that checks incoming prompts against security rules, blocking those matching high-severity security or jailbreak patterns while authorizing safe prompts.

Catalyst puts a governance layer between AI agents and consequential actions. Before your agent writes files, sends messages, deploys code, or calls external APIs, it checks in with Catalyst. Depending on your policy, actions are allowed immediately, routed to a human for approval, or denied. Includes 8 pre-built compliance framework packs (GDPR, SOC 2, ISO 27001, HIPAA, PCI-DSS, EU AI Act, Briber

Prevents autonomous agents from fabricating tool results by verifying HMAC-signed receipts against epistemic claim types, forcing re-grounding or escalation before actions commit.

Enables querying the abuse.ch MalwareBazaar database for malware samples by tag, family, signature, or recent submissions.

Enables an AI agent to send or draft email as the signed-in user through Microsoft Graph, including multiple recipients, HTML or plain-text bodies, and file attachments. Uses delegated least-privilege PKCE authentication so messages can be staged as drafts for approval or sent directly.

A safety guard for AI assistants that inspects actions (file reads, queries, etc.) and classifies them as SAFE, SUSPICIOUS, or BLOCK with explanations, using both known-attack patterns and behavior-based zero-day detection.

Enables email validation and domain checking to detect disposable or temporary email addresses via the Disify API, providing formatting, DNS, risk flags, and classification.

Enables MCP-capable runtimes to read agent message rooms, sign and post public messages, and create or verify Ed25519 contribution proofs for Technocore.

Provides secure, ephemeral secret management for AI agents via MCP tools that self-destruct after use or session end.

Offers proof-only tools to inspect and verify remediation closure receipts, deterministically confirming asset coverage, fixed artifact deployment, rescanning, deadline compliance, and zero-residual closure without executing scans or touching live systems.

A deterministic identity and authorization layer for MCP servers that verifies agent identity and scope using OAuth 2.0, WIMSE workload identity, and HTTP Message Signatures, resolving or refusing without guessing.

A general-purpose MCP connectivity layer that bridges MCP clients to authenticated remote MCP servers, managing authentication, credentials, routing, and connection lifecycle. It enables clients like OpenHands Cloud to securely connect to remote MCP servers such as Notion.

A policy-based security layer for AI agents and MCP tools that evaluates tool requests against security policies before allowing, denying, or requiring human approval for execution.
