Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
MCP server for AI agent payments. An agent in Cursor, Claude Code, Claude Desktop, Codex, or any MCP host can call paid APIs (search, scraping, contact data, public records, compute, media, research) from one balance, with a spend ceiling it states on every call, and no vendor keys anywhere in its environment. Billed only on success (x402 USDC on Base, Stripe MPP, or Tempo); a refused or failed call costs nothing.
npx @vaaya/mcp install # Cursor, Claude Code, Claude Desktop, Codex claude mcp add --transport http vaaya https://vaaya.ai/mcp
First paid call: consult returns a priced plan; use({ service, action, params, max_cost_cents }) runs one line of it. If the quoted price is above max_cost_cents, the call is refused before it reaches the provider and the reason comes back:
{ "error": "over_max", "message": "price is 5¢ but max_cost_cents was 1", "price_cents": 5 }Runnable examples: examples/pay-for-an-api (one call allowed, one refused), examples/cursor, examples/claude. Guides: give an agent a budget, Cursor setup, Claude setup, what is an AI agent wallet.
Buy tokenized shares — including with Instinct
Agents can buy supported tokenized stocks on Base with Vaaya prepaid funds. These are tokenized stocks, not direct brokerage shares. Discover the current supported tickers with stocks({ command: "list" }) (for example Apple AAPLc and NVIDIA NVDAc), then check stocks({ command: "portfolio" }) for buyingPowerCents. Welcome grants and credit lines cannot buy shares.

Questions
What is the Vaaya MCP server?
Paid APIs and supported tokenized shares for agents, funded with prepaid balance. Instinct Checkout guidance: https://vaaya.ai/llms.txt
Is Vaaya safe to connect to an agent?
No — not without reading the findings first. The audit graded it D (69/100) and found 3 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does Vaaya need?
It reads VAAYA_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Vaaya run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as vaaya-glama-introspection-server at 1.0.0.
How current is this page?
The grade is for one exact copy of the source (eb8da16c838b), read on 2026-10-08. The repository is watched and re-audited when it changes.
