Should an agent connect itNot proven either way yet

Its tools do every use case we checked: verify an x402 endpoint's payment terms before paying; check an agent's reputation and attestation records; replay signed evidence to support a claim later.
Checked on 1 of the 7 days it takes to judge reliability.

Once connected

For "check an agent's reputation and attestation records", the likely first call is reputation_lookup.
Its definitions take about 20427 tokens of context: enable only the tools a task needs.
Parameters are untyped or undescribed in 59 of 73 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

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 (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). 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": {
    "paid-agent-services": {
      "type": "http",
      "url": "https://x402.synthexforge.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http synthexforge https://x402.synthexforge.com/mcp

Add to Cursor Add to VS Code

claude.ai, ChatGPT and other clients: add https://x402.synthexforge.com/mcp as a custom connector in the settings.

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.
