Settld MCP Payments Skill

This skill teaches OpenClaw agents to use Settld for paid MCP tool calls.

What This Skill Enables

• Discover Settld MCP tools (settld.*)
• Run paid tool calls with x402 challenge/authorize/retry flow
• Return verifiable payment/settlement headers from tool responses
• Produce audit-grade artifacts and receipts in Settld

Prerequisites

• Node.js 20+
• Settld API key (SETTLD_API_KEY)
• Settld API base URL (SETTLD_BASE_URL)
• Tenant id (SETTLD_TENANT_ID)
• Optional paid tools base URL (SETTLD_PAID_TOOLS_BASE_URL)

MCP Server Registration

Use the server definition in mcp-server.example.json.

Server command:

• command: npx
• args: ["-y","settld-mcp"]

Required env vars:

• SETTLD_BASE_URL
• SETTLD_TENANT_ID
• SETTLD_API_KEY

Optional env vars:

• SETTLD_PAID_TOOLS_BASE_URL
• SETTLD_PROTOCOL

Agent Usage Pattern

1. Call settld.about to verify connectivity.
2. For paid search/data calls, use:
• settld.exa_search_paid
• settld.weather_current_paid
3. For agreement lifecycle demo calls, use:
• settld.create_agreement
• settld.submit_evidence
• settld.settle_run
• settld.resolve_settlement

Smoke Prompts

• "Call settld.about and return the result JSON."
• "Run settld.weather_current_paid for Chicago in fahrenheit and include the x-settld-* headers."

Safety Notes

• Treat SETTLD_API_KEY as secret input.
• Do not print full API keys in chat output.
• Keep paid tools scoped to trusted providers and tenant policy.
