AgentTrust stdio MCP server giving AI agents verified identity with email, instant messaging, and cloud file storage across 19 Ed25519-signed tools.

macOS app and bundled stdio MCP server that lets Claude access selected local services such as Calendar, Contacts, Messages, Location, Maps, Reminders, camera, microphone, screenshots, Shortcuts, utilities, and Weather.

Expert MCP capability skill for secure server authoring, tool schema discipline, authorization boundaries, and prompt-injection risk review.

Secure MCP servers with strict tool boundaries, auth controls, dependency hygiene, and abuse-resistant runtime policies.

PreToolUse hook that blocks edits adding remote MCP server URLs unless their host appears in an explicit allowlist, reducing accidental connection to unreviewed OAuth, SSE, or Streamable HTTP MCP endpoints.

Source-backed agent that threat-models an MCP server before it is connected to Claude Code, covering trust verification, tool authority and side effects, prompt injection via tool output, network and credential exposure, and least-privilege mitigations, grounded in the official security docs.

A source-backed guide for designing Model Context Protocol servers with explicit authorization boundaries, narrow tools, scoped resources, privacy-aware logging, and least-privilege runtime access.

Configure MCP servers in the Claude Desktop app by editing claude_desktop_config.json. Grounded walkthrough covering config file locations, the mcpServers JSON structure, the filesystem server, and how to verify and troubleshoot the connection.

49 remote MCP security tools for CVE/KEV/CWE/EPSS lookup, composite CVSS+EPSS+KEV+PoC risk scoring, CVSS v3.x vector parsing, domain/IP/IOC enrichment, dependency and web intelligence checks, MITRE ATLAS AI/ML attacks, and MITRE D3FEND defenses. Anonymous tier available; Pro tier uses an API key.

Fullstack MCP framework for building MCP servers, MCP Apps, MCP agents, and MCP clients with TypeScript and Python SDKs, scaffolding, inspector tooling, hosted deployment, observability, OAuth, notifications, sampling, and agent integrations.

Microsoft open-source Model Context Protocol curriculum with hands-on MCP server, client, security, transport, auth, deployment, Azure, VS Code, Inspector, PostgreSQL, and cross-language examples.

Remote MCP server for X and Twitter automation: tweet search, profile timelines, follower export, media workflows, webhooks, and confirmation-gated write actions.

Decision-assurance layer for AI agents: returns calibrated Decision Assets and an auditable action boundary (approve / review / block / seek-evidence) plus a verifiable Decision Receipt before high-stakes actions. Advisory only — never transacts or modifies identity. MCP tools: health_check and bench_query.

Connect existing MCP servers to Claude Code with claude mcp add: stdio, HTTP, and SSE transports, local/project/user scopes, .mcp.json, and /mcp OAuth.

A practical walkthrough of Claude Code channels: how an MCP-server channel pushes messages, alerts, and webhooks into a running session, how to install and enable Telegram, Discord, or iMessage, sender allowlists, and enterprise controls.

The official SingleStore MCP server (singlestore-mcp-server) that lets AI assistants manage SingleStore from natural language — running SQL on a workspace, inspecting organizations, workspace groups, and workspaces, managing starter workspaces, notebooks, scheduled jobs, and Stage files — with no API keys required thanks to browser-based OAuth.

The official Tigris MCP server (@tigrisdata/tigris-mcp-server) that connects AI agents to Tigris, a high-performance S3-compatible object storage system — listing, creating, and deleting buckets; listing, uploading, and deleting objects; creating folders and files; and generating shareable links — using S3-style access keys against the Tigris endpoint.
