## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 71/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 404, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 56/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 18804 tokens (~313/item across 60 items; 60 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 60 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 60 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the io.github.CryptoAPIs-io/mcp server?

io.github.CryptoAPIs-io/mcp is a hosted endpoint at https://ai.cryptoapis.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

• get-subscription: Get details of a specific subscription by its referenceId
• delete-subscription: Remove a subscription (stops webhook delivery)

### `blockchain_events__blockchain_events_create` (~621 tokens)

Create a webhook subscription for on-chain events. When the specified event occurs, CryptoAPIs sends a POST request to your callbackUrl with the event data. Subscriptions persist until deleted.

Event types (supported blockchains vary per type — an invalid blockchain for the chosen eventType is rejected before calling the API):
• address-coins-transactions-unconfirmed: fires when an unconfirmed coin transaction touches the address
• address-coins-transactions-confirmed: fires once a coin transaction confirms (optionally on an exact confirmation via receiveCallbackOn)
• address-coins-transactions-confirmed-each-confirmation: fires on every confirmation up to confirmationsCount (required)
• address-tokens-transactions-confirmed: fires once a token transfer confirms
• address-tokens-transactions-confirmed-each-confirmation: fires on every confirmation up to confirmationsCount (required)

All event types except block-mined require an address.

Note: 'create' actions require confirmation. They return a preview with a one-time token instead of executing immediately.
