Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Payperwork index. Paid services for agents over x402 (USDC on Base): no signup, the paying wallet is the identity, every call is priced before it runs and charged only if it succeeds. This server only describes the services; each one is its own MCP server: drop at https://payperwork.app/drop/mcp (temporary key-value drops and hand-off channels; put $0.002, wait $0.001, reads free) and ai at https://payperwork.app/ai/mcp (chat completions on frontier models, priced per call from the request). Call list_services, then describe_service for the one you want and connect to its URL. Plain text: https://payperwork.app/llms.txt. Security model: every call is priced before it runs (the 402 states the amount) and charged only if it succeeds; the paying wallet is the identity; no account or key exists to revoke. Full statement: GET / (JSON) or /llms.txt.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http payperwork-mcp https://payperwork.app/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add payperwork-mcp --url https://payperwork.app/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable payperwork-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "payperwork-mcp": {
      "url": "https://payperwork.app/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "payperwork-mcp": {
      "type": "streamableHttp",
      "url": "https://payperwork.app/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start payperwork-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "payperwork-mcp": {
      "type": "http",
      "url": "https://payperwork.app/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http payperwork-mcp https://payperwork.app/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "payperwork-mcp": {
      "url": "https://payperwork.app/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "payperwork-mcp": {
      "serverUrl": "https://payperwork.app/mcp"
    }
