"How to connect to a REST API" matching MCP servers:

An MCP server that sends plain-text Gmail messages only to a predefined allowlist, using generated recipient IDs instead of email addresses to enforce security.

Enables AI assistants to manage pfSense firewalls using 17 tools for system status, firewall rules, DHCP, DNS, monitoring, and service management via the pfSense REST API.

Enables coding agents to read, query, and safely modify RouterOS 7 devices over the REST API, covering firewall, routing, DHCP, DNS, interfaces, containers, files, and diagnostics, with confirmation gates and a scheduled rollback guard in front of disruptive changes.

Enables teams to securely store and retrieve credentials, view decrypted secrets or live OAuth tokens, and connect to third-party MCP servers through a unified MCP endpoint.

Provides security scanning capabilities through Snyk CLI tools and REST API, enabling AI assistants to test projects for vulnerabilities, retrieve security issues, and manage Snyk projects with comprehensive SAST, container, and infrastructure as code scanning.

Enables Claude and other MCP clients to search, read, write and organise mail on Stalwart servers over JMAP — including folders, Sieve filters, out-of-office replies and one-click unsubscribe — with draft-first and confirmation safeguards against prompt injection. A separate admin endpoint additionally exposes account, domain, mailing-list, queue, IP, log and task management through Stalwart's JMAP management API.

An MCP server that enables interaction with Xero's Identity Service API, providing OAuth 2 authentication and identity management capabilities through natural language commands.

Routes web requests from AI tools through Tor for anonymized fetching, with selective per-URL routing to bypass Tor-blocking sites.

SOC2 Compliance AI - MCP server providing AI-powered tools and automation by MEOK AI Labs

Enables LLM agents to browse and triage vulnerability observations, manage products, branches and rules, import scan reports and SBOMs, run scans and background jobs, and generate VEX documents via SecObserve's REST API.

An MCP server that reads a file's embedded C2PA Content Credential to report whether it declares AI generation or a real-world capture, and checks whether that declaration's signature still verifies against the file's current bytes.

Enables checking of package vulnerabilities and supply-chain risks using Attestd API. Supports single and batch checks, CVE details, and covered products listing.

Enables AI agents to read and send email, handle attachments and manage calendar invitations through their own IMAP/SMTP mailboxes, with per-mailbox sender and recipient allow lists and automatic HTML-to-Markdown conversion. It runs as a single self-hosted Docker container, exposing the same tools over MCP and REST.

MCP server for Speakeasy — Windows API emulation for binary analysis. It runs a .exe in a Wine-like sandbox and returns a structured API trace.

Cybersecurity AI - MCP server providing AI-powered tools and automation by MEOK AI Labs

Connect your database to your AI agent, read-only, without sharing your password. Maplith Bridge serves a folder of data files over MCP behind a token you create, and fills it from PostgreSQL under a role that can only read.

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 read identification verdicts, search history, summarize entities, explain risk scores, and verify webhook signatures through read-only tools over stdio or streamable HTTP.

Enables MCP-speaking agents to execute tool calls through an authorization gate, producing signed decision records and reconciled effect rows for accountability.

A Model Context Protocol server for Conan package manager integration, enabling dependency management, project creation, and security scanning via natural language.
