The Stall

What thebrierfox/the-stall MCP server does

Thebrierfox/the-stall MCP server provides a catalog of 210 live, individually priced capabilities through MCP. The catalog spans US and global equity data, options and dealer GEX analysis, macroeconomic indicators, congressional trades, prediction markets, crypto and DeFi research, EVM and Solana analysis, SEC filings, weather, aviation, research, and general data utilities.

Capabilities range from focused lookups to combined research operations. Examples include checking a wallet's security reputation, retrieving a Base or Ethereum block header, searching arXiv, inspecting DeFi protocol TVL, looking up aviation weather, analyzing an image URL, and generating an AI image. The complete list and current prices are available from the service catalog.

How it works

the thebrierfox/the-stall MCP server is available at https://the-stall.intuitek.ai/mcp as a streamable HTTP endpoint that accepts POST requests. Agents can discover service metadata through the agent card at /.well-known/agent.json, payment information through /.well-known/x402, and available capabilities through /catalog.

Each capability is exposed through a corresponding /cap/<name> HTTP route. With the crypto payment flow, a request that has not been paid returns HTTP 402 with the USDC price. Payment is completed on Base mainnet through the x402 facilitator, after which the result is returned. The service also supports prepaid Stripe credits: a developer purchases a bundle, obtains a bearer token, and sends that token with later capability requests.

Setup and configuration

No API key, signup, or monthly subscription is required. For agent or wallet-based use, the caller needs an x402-compatible payment flow and USDC on Base mainnet. The README does not provide a local package installation command; use the hosted MCP endpoint directly.

For card payments, the checkout endpoint is POST https://the-stall.intuitek.ai/v1/fiat/checkout with a bundle such as starter, pro, or scale. After checkout, GET https://the-stall.intuitek.ai/v1/fiat/token?session_id=<id> returns a bearer token. Requests can then include Authorization: Bearer <token>. The listed bundles are $5 for 100 credits, $30 for 1,000 credits, and $200 for 10,000 credits.

Tools and capabilities

The catalog includes tools for:

• Equity research, analyst ratings, SEC company information, commodities, credit spreads, and congressional trades.
• Crypto prices, market movers, fear and greed, news impact, DeFi protocol metrics, portfolio scanning, and yield intelligence.
• Blockchain inspection across Base, Ethereum, Arbitrum, EVM wallets, and Solana-related analysis.
• Weather and air-quality data, airport and city lookup, and aviation METAR and TAF reports.
• Academic search, books, clinical trials, citations, dictionaries, and structured web extraction.
• Image generation, image understanding, code analysis, changelog formatting, and technical calculators.

Prices vary by capability, with examples in the catalog ranging from $0.001 to $0.350 per call.

Limitations and notes

The service is pay-per-call rather than free local software. Calls require either USDC payment on Base or prepaid Stripe credits, and the README does not describe an offline mode. Capability availability and prices may change; the README identifies the catalog as version 4.64.0 and directs clients to /catalog for the current list. External data freshness, coverage, and provider behavior will depend on the individual capability and its stated source.
