Coin Signal

What coin-signal MCP server does

The coin-signal MCP server exposes crypto market signal capabilities through MCP. Its documented outputs cover three related functions: bottom signals, top signals, and a per-coin result containing a verdict and score. It also supports market scans for reviewing signal conditions across coins.

The listing identifies the service as a finance and fintech tool focused on cryptocurrency. That makes it relevant for agents that need to retrieve signal-oriented market information as part of an analysis workflow. The available description does not specify which coins, markets, time ranges, or scoring methodology are supported.

How it works

An MCP-compatible agent calls the coin-signal MCP server to request signal data or a market scan. Results are described at a high level as a verdict and score per coin, along with bottom/top signal outputs. The service uses x402 pay-per-call access, so calls are associated with payment rather than being described as an unrestricted free interface.

The supplied material does not explain the request schema, response fields beyond verdict and score, payment settlement flow, or whether calls require a wallet, token, or other credential. Those details should be confirmed from the service documentation before implementation.

Tools and capabilities

Documented capabilities include:

• Retrieving crypto bottom signals.
• Retrieving crypto top signals.
• Getting a verdict and score for each coin.
• Running market scans.
• Accessing functionality through pay-per-call x402.

The description does not provide formal tool names, argument lists, return schemas, supported assets, or examples. Treat the capabilities above as the published feature scope rather than a complete API reference.

Limitations and notes

The coin-signal MCP server’s available listing is brief, and its README is unavailable. It does not establish compatibility with a specific desktop client, editor, coding agent, or orchestration framework. It also does not state an installation command, transport type, environment variables, license, authentication procedure, or x402 payment setup.

Before selecting the coin-signal MCP server for production use, verify how an MCP client connects, how payments are authorized and settled, which assets are covered, and how signal freshness and scoring are represented. The available material supports using it for crypto signal retrieval and market scans, but not conclusions about signal accuracy or trading outcomes.
