35+ local compute tools for AI agents — plus a hosted, conformal-calibrated pricing oracle
Run it fully local with zero cloud dependency, or connect to the hosted endpoint at mcp.the-undesirables.com — pay-per-call in USDC, no account or API key.
https://mcp.the-undesirables.com
No install, no account, no API key. 12 tools over streamable HTTP (MCP protocol
2025-06-18; legacy SSE also served). Free tools answer immediately. Paid tools return an
x402 payment_required carrying amount, network, and payTo — an agent with a funded
wallet can settle and retry in the same session. Settlement only occurs on a successful
response; failed calls are never charged.
Holders can also ask which Undesirables a wallet owns and how each soul's calls have
scored (souls_in_wallet, soul_calls) — public track record only; personalities stay
holder-gated.
Claude Desktop / Perplexity — add it as a custom remote connector (Perplexity: Settings → Connectors → + Custom Connector → Remote).
Cursor / Windsurf / VS Code — clients that take a URL in config:
{
"mcpServers": {
"tcg-oracle": { "url": "https://mcp.the-undesirables.com" }
}
}
Tools: search_tcg_products, market_snapshot, grade_card, grade_or_not,
simulate_price, card_forecast, trending_cards, optimize_portfolio,
recommend_workflow, check_accuracy.
Search is set-aware — search_tcg_products("Base Set Charizard") separates Base Set,
Base Set 2, and Shadowless rather than returning every Charizard printing. Every result
carries a set field and a product_id you can pass straight to the other tools.
