MaxWorth MCP server
Which MCP servers are MaxWorth's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?
Worth a look
None of the five warning signs in these definitions.
A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

How to connect
Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:
{
"mcpServers": {
"maxworth-public": {
"type": "http",
"url": "https://mcp-public.maxworth.app/mcp"
}
}
}Add it
Claude Code, in a terminal
claude mcp add --transport http maxworth https://mcp-public.maxworth.app/mcpclaude.ai, ChatGPT and other clients: add https://mcp-public.maxworth.app/mcp as a custom connector in the settings.
- app.maxworth/maxworthanswers, requires sign-inverified in the MCP registry
Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
