Alternatives to 402registry
Remote MCP server (Streamable HTTP, no account, no API key) for 402registry, which checks whether AI agents and AI crawlers can actually see a website: a plain HTTP fetch with no JavaScript, the way GPTBot, ClaudeBot, PerplexityBot and OAI-SearchBot fetch pages. Every finding quotes what the fetch returned, with a fix. Tools: lookup_site (free), get_pricing (each product with its price and the exact x402 v2 payment requirements), get_docs (the machine guide as JSON) and get_service_status. A check costs $0.01, paid per request over x402 in USDC on Base.
402registry is tagged API. The servers below cover similar ground, ranked by how many tags they share with it, then by GitHub stars.

by Shashank Agarwal
API.market provides a proprietary hosted Streamable HTTP MCP gateway for API discovery and execution. Endpoint: https://api.market/api/mcp/gateway. Its five tools are search_apis, get_api_tools, call_api, check_usage and manage_subscription; it also exposes two resources and two prompts. An API.market account and OAuth or an API key are required. Free tiers and paid plans vary by API. Claude Code connection and tool discovery have been verified; this does not establish every API operation or client has been tested. After adding the remote server, authenticate through /mcp in Claude Code. Setup: https://api.market/mcp. Contact: shashank@noveum.ai. Submitted by the API.market team; the hosted implementation is not open source.

Arcmira: YouTube Transcript Search
by Zeal Caiden
Search indexed YouTube and podcast transcripts for timestamped quotes, speaker appearances, mentions, sponsors and recommendations. Find clips to review and follow links back to the original videos. Premium transcripts add speaker identification; check the linked source when attribution matters. Coverage and capabilities depend on account access. A paid read uses credits from your plan, then your on-demand budget. Arcmira: https://arcmira.com API documentation: https://arcmira.com/docs MCP setup: https://arcmira.com/docs/mcp-server Note: the write tool (arcmira_execute_write) creates and changes monitors, never deletes, and is flagged destructive in its own annotations. Tool calls are logged in product analytics per the maker docs.

by Master King
BlockVectra MCP connects AI agents to multi-chain EVM RPC and indexed Data API tools. Documentation, chain discovery, status, pricing and supported public RPC reads are keyless. Data API and account tools require your own BlockVectra API key; access to RPC methods depends on each chain's public method policy. Connect to the hosted Streamable HTTP endpoint or use the MIT-licensed stdio bridge with Node.js 22+. A separate tool can broadcast an already signed transaction; never supply private keys. Documentation: https://docs.blockvectra.com/en/guides/mcp-server/ Hosted endpoint: https://docs.blockvectra.com/mcp
