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.

MCP Score is an independent trust registry that evaluates and rates Model Context Protocol (MCP) servers. It addresses the need for transparency and trust in the MCP server ecosystem by providing nightly updated scores based on multiple criteria, including security, freshness, adoption, quality, and trust. The platform is designed for users seeking to assess the reliability and security of MCP servers, such as developers, organizations, or anyone integrating with MCP-based tools. The scoring methodology is public and versioned, allowing users to understand how each server's MCPScore (ranging from 0 to 100) is calculated. The score is determined by weighted factors: security (35%), freshness (25%), adoption (20%), quality (10%), and trust (10%). MCP Score highlights top-rated servers, most downloaded servers, new arrivals, security risks, and servers experiencing score drops. Users can search and filter through a directory of over 46,000 MCP servers, browse by category (such as Databases, Dev Tools, Web Scraping, Automation, AI & ML, Finance, Monitoring, Communication, Search, Storage, and others), and compare servers based on score, stars, downloads, and other metrics. The registry covers MCP servers distributed via npm and PyPI, as well as those hosted on GitHub, and provides detailed listings with weekly download counts and repository star numbers. Users can monitor score changes, check for regressions, and identify potential security risks. The platform emphasizes its independence by stating it does not accept vendor money, reinforcing its position as an unbiased source of trust ratings for MCP servers. MCP Score is delivered as a web-based service accessible through its website. It serves as a resource for evaluating the security and trustworthiness of MCP servers across a wide range of categories and use cases.
