orchard-data-mcp

MCP server for orchard-data — pay-per-call market data for AI agents over x402 (USDC micro-payments on Base). No account, no API key, no subscription.

Try it before you spend anything. Three tools cost nothing and need no wallet: list_products, get_fear_greed, and get_feed_status.

The flagship tools are data you cannot get elsewhere: an ML market-regime forecast, a news catalyst radar, and a track record you can audit — predictions are recorded before the outcome and scored server-side against what actually happened, with the scoring rule shipped inside the payload. Produced by a real algorithmic trading system, refreshed ~15 min during US market hours, staleness always reported and never hidden.

Setup

Paid tools need a small dedicated Base wallet holding USDC (a few dollars goes a very long way at these prices). Use a burner wallet, never your main one.

{
  "mcpServers": {
    "orchard-data": {
      "command": "npx",
      "args": ["-y", "orchard-data-mcp"],
      "env": { "EVM_PRIVATE_KEY": "0x<burner wallet private key>" }
    }
  }
}

Without EVM_PRIVATE_KEY the three free tools still work, and the paid tools explain what they would cost rather than failing silently.

How payment works

Each paid tool call: GET → HTTP 402 with payment requirements → the client signs a USDC transfer authorization with your key → retries with the payment header → JSON. Settlement is gasless for the buyer (EIP-3009 via the x402 facilitator). Verified end-to-end on Base mainnet.

TDQS

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden and does well: it discloses the refresh frequency (~15min during US market hours) and source (AI news scanner). It does not mention rate limits or auth needs, but for a read-only tool this is sufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no extraneous information. The key facts are front-loaded, and every word adds value. Perfectly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter tool with no output schema, the description provides reasonable expectations: tickers with bullish catalysts and refresh timing. It could mention output format (e.g., list), but is otherwise complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so baseline is 4. The description adds no parameter details, which is appropriate given the empty input schema and 100% schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it provides tickers with fresh bullish news catalysts, making the tool's purpose immediately obvious. The verb 'get' and resource 'catalyst radar' are explicitly defined.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives, though no sibling tools exist. The description implies use during US market hours due to refresh timing, but lacks explicit when-to-use or when-not-to-use context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Disambiguation5/5

Only one tool exists, so there is no possibility of confusion with other tools.

Naming Consistency5/5

Single tool adheres to a clear verb_noun pattern (get_catalyst_radar).

Tool Count3/5

With only one tool, the server's scope is very narrow; while it may be sufficient for a single purpose, it feels thin compared to typical MCP servers.

Completeness5/5

For the stated purpose of providing AI-scanned bullish news catalysts, a single retrieval tool is complete; no obvious gaps in functionality.
