Nordprix MCP Readiness Check

Nordprix MCP Readiness Check tests a remote MCP server against the requirements Anthropic publishes for the Connectors Directory, before you submit it. Give Claude your server's https:// URL and the check_mcp_server tool reports, check by check, whether the server answers MCP over Streamable HTTP (the 2026-07-28 protocol and the earlier initialize handshake), which authentication type it uses, whether its OAuth discovery is complete (401 challenge, protected resource metadata, authorization server metadata, issuer, DCR or CIMD, PKCE S256, response times), and whether its tools follow the directory's tool rules: titles, readOnlyHint or destructiveHint annotations, name length, descriptions, no mixed read/write HTTP tools, API references on free-form query tools, and prompt-injection patterns. Each failed or warning check comes with the evidence, a fix and a documentation link. If your tools are behind sign-in, paste a signed-in tools/list result and check_tools_list runs the tool rules on it without contacting any server. What is sent to your server: the MCP handshake, tools/list (at most 5 pages) and GET requests for OAuth discovery documents. It never calls your tools, never registers an OAuth client, never requests a token and sends no credentials. Only public https:// addresses are checked, and nothing you submit is stored. The check covers what can be tested from outside a server. It is not a review decision by Anthropic, and Nordprix is not affiliated with Anthropic.
