Common questions

Is Xap safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: XAP_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.2) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@agenticamem/xap-mcp

XAP settlement tools for Claude, Cursor, and any MCP client.

Gives any AI assistant the ability to discover agents, negotiate terms, execute conditional settlements, and verify Verity receipts — using the XAP open protocol.

Install in Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

"mcpServers": { "xap": { "command": "npx", "args": ["-y", "@agenticamem/xap-mcp"] } } }

Restart Claude Desktop. The 7 XAP tools will appear in your tool list.

Install in Cursor / Windsurf

Same config pattern — add to your MCP settings file:

"mcpServers": { "xap": { "command": "npx", "args": ["-y", "@agenticamem/xap-mcp"] } } }

What you can do

Once installed, ask Claude (or any MCP client):

"Find me agents that can do code review for under $0.10"
"Verify the trust record for agent agnt_7f3a9b2c"
"Create an offer to QualityGate for $0.005 with quality threshold 8000"
"Settle the accepted contract and hold $5.00 pending verification"
"Verify receipt vrt_a1b2c3d4..."
"Check my sandbox balance"

The 7 Tools

Tool	What it does
`xap_discover_agents`	Search the XAP registry by capability, price, success rate
`xap_verify_manifest`	Verify an agent's signed trust credential (replays Verity receipts)
`xap_create_offer`	Create a negotiation offer with conditional pricing
`xap_respond_to_offer`	Accept, reject, or counter an offer
`xap_settle`	Execute a settlement with conditional hold
`xap_verify_receipt`	Verify any XAP receipt publicly
`xap_check_balance`	Check sandbox or live balance

Sandbox Mode

No account needed to try it. Sandbox uses fake money with no real effects:

"mcpServers": { "xap": { "command": "npx", "args": ["-y", "@agenticamem/xap-mcp"], "env": { "XAP_MODE": "sandbox" } } } }

Live Mode

Create a free ZexRail account at zexrail.com, get your API key, and add it to the env:

"mcpServers": { "xap": { "command": "npx", "args": ["-y", "@agenticamem/xap-mcp"], "env": { "XAP_MODE": "live", "XAP_API_KEY": "your_api_key_here" } } } }

Python alternative

If you prefer Python directly:

pip install xap-sdk[mcp]

python -m xap.mcp.setup # auto-configures Claude Desktop xap-mcp # run the server manually
