Canopii Trust Index is a platform that provides security scores for MCP servers by independently scanning and evaluating each server for various risks. The tool addresses concerns such as tool poisoning, prompt injection, supply-chain vulnerabilities, and credential risks within the MCP ecosystem. Each server is assessed on a per-version basis, and a single security score is assigned before agents connect, helping users make informed decisions about which servers to trust. The platform maintains a continuously updated registry of MCP servers, with the evidence noting that over 12,000 servers have been scored. It offers a breakdown of security grades, including the proportion of servers rated from A (strong posture) to F (high risk). Users can browse the registry to view these scores and see the distribution of security postures across the ecosystem. Additionally, the service identifies endpoints that are live-verified and those that are unverifiable. Canopii Trust Index also features an API, allowing users to check the security score of any MCP server from their own tools. This API is key-authenticated and rate-limited, facilitating integration into workflows such as CI gates, procurement reviews, or agent allow-lists. The evidence highlights that the platform is suitable for scenarios where automated or programmatic access to security scores is required. The service is web-based, as indicated by the ability to browse the registry online and request API access. No specific pricing or licensing information is provided in the available evidence. The tool is positioned as a specialized registry and scoring system for MCP servers, focusing on security assessment and risk visibility within this ecosystem.

MCPSafe is a security scanner designed specifically for Model Context Protocol (MCP) servers, offering pre-install audits to identify vulnerabilities and threats before deployment. The platform is aimed at developers who need to vet MCP servers prior to installation, as well as registry operators responsible for publishing secure catalogs. It provides both fast and deep scans, delivering a quick verdict in approximately three minutes and a more thorough consensus-based analysis in about twenty minutes. The tool combines static analysis with evaluations from five independent large language models (LLMs) to detect a wide range of issues. Its static analysis capabilities identify code-level vulnerabilities such as command injection, SQL injection, server-side request forgery (SSRF), path traversal, and hardcoded secrets. The LLM consensus approach uncovers more complex threats including tool poisoning, silent rug pulls, indirect prompt injection, and obfuscated intent that may evade traditional pattern matching. MCPSafe also performs typosquatting checks to flag lookalike package names, unverified publishers, and unpinned dependencies, helping to prevent supply chain attacks. A permission audit feature evaluates each tool’s real-world access, highlighting excessive permissions, weak authentication, and unintended network exposure. MCPSafe supports scanning a variety of sources, including GitHub repositories, npm and PyPI packages, Docker images, and MCP registry IDs. Users can specify a particular version for targeted analysis. The platform provides actionable score reports using the AIVSS (AI Vulnerability Scoring System), which extends traditional vulnerability scoring with factors relevant to agentic threats, and maps findings to CWE standards. Each scan generates a live SVG badge that can be embedded in documentation to display the current security grade. Results are kept up-to-date by fingerprinting the commit or version on every request, with rescans triggered automatically for new commits. The service is delivered as a web-based platform and is free to use, requiring no signup or credit card for public package scans. Signed-in users benefit from higher rate limits and access to scan history. MCPSafe is developed and operated from Germany.

MCP Pre-Flight is a web-based submission auditing tool designed for developers preparing Model Context Protocol (MCP) servers for listing in the Claude and OpenAI directories. The platform addresses the challenge of ensuring that MCP server implementations meet directory requirements before undergoing formal review, aiming to catch common mismatches and issues that can lead to rejection. The tool performs a multi-layered audit process. At the wire level, it checks OAuth 2.1 with PKCE, dynamic client registration, authorization, token exchange, refresh flows, and MCP protocol endpoints such as initialize, tools/list, and tools/call. It also tests for resilience to malformed bodies and unknown methods. Each safe-to-invoke tool exposed by the MCP server is actually called with synthesized arguments to verify correct invocation. For tools that claim idempotency, the platform runs an idempotency probe by calling them twice and comparing the results. MCP Pre-Flight offers optional source-side analysis by accepting a GitHub repository URL. It uses the GitHub API to fetch the repository and runs an abstract syntax tree (AST) check, ensuring that handler implementations match their annotations. The tool also verifies that the README file mentions every tool declared in the source code. Additionally, it analyzes the language of responses for vocabulary that may contradict the tool's annotations. Each audit finding is tagged with the relevant directory—Claude or OpenAI—that the issue pertains to. The tool requires the HTTPS endpoint of a deployed MCP server, specifically one that responds to JSON-RPC tools/list. If OAuth is present, MCP Pre-Flight tests the full authentication flow. Authenticated checks can be unlocked by providing a test bearer token. For source analysis, public repositories can be used without authentication, while private repositories require a personal access token. MCP Pre-Flight is delivered as a free web tool. By simulating the directory review process and highlighting issues in advance, MCP Pre-Flight helps developers reduce the risk of delayed or rejected submissions when targeting the Claude and OpenAI directories.
