What this MCP does

Provides access to hosted LLM inference pools, connection details, subscription management, and USDC payments on Base.

Capabilities

Tools

7 tools
confirm_crypto_subscription
Confirm a USDC payment and receive your API key
After sending the quoted USDC amount on Base, submit the transaction hash plus an EIP-191 signature of the claim message (from get_crypto_quote) made with the paying wallet. Verifies the payment on-chain and returns your API key. Idempotent: safe to retry with the same tx_hash.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['tx_hash', 'pool_slug', 'blocks', 'signature'], 'properties': {'blocks': {'type': 'array', 'items': {'type': 'string'}, 'minItems': 1, 'description': 'Same blocks the quote was for'}, 'tx_hash': {'type': 'string', 'description': 'Base L2 transaction hash of the USDC transfer'}, 'pool_slug': {'type': 'string'}, 'signature': {'type': 'string', 'description': 'EIP-191 signature of the claim message by the paying wallet'}}, 'additionalProperties': False}
get_card_checkout_link
Get a card checkout link
Card payments require a browser (3-D Secure). Returns the dashboard page for the pool where a human can complete checkout. Card subscriptions auto-renew monthly until cancelled.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['pool_slug'], 'properties': {'pool_slug': {'type': 'string', 'description': 'Pool slug from list_pools'}}, 'additionalProperties': False}
get_connection_info
How to connect
OpenAI-compatible and Anthropic base URLs plus ready-to-paste client snippets. Works with or without a key (keyless: explains subscribe and x402 pay-per-request options).
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'api_key': {'type': 'string', 'description': 'Optional pool subscription key to embed in the snippets'}}, 'additionalProperties': False}
get_crypto_quote
Get a USDC subscription quote
Quote for subscribing to a pool with USDC on Base: exact amount, payment address, and the claim message you must sign after paying. Crypto subscriptions are one-time 30 days (no auto-renewal).
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['pool_slug', 'blocks'], 'properties': {'blocks': {'type': 'array', 'items': {'type': 'string'}, 'minItems': 1, 'description': 'One or more block names from get_pool (all of them = 24/7)'}, 'pool_slug': {'type': 'string', 'description': 'Pool slug from list_pools'}}, 'additionalProperties': False}
get_pool
Get pool details
One pool in detail: models, per-block prices, availability, and what the subscription includes.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['pool_slug'], 'properties': {'pool_slug': {'type': 'string', 'description': 'Pool slug from list_pools'}}, 'additionalProperties': False}
get_subscription_status
Check a subscription key
Status of a pool subscription key: pool, reserved daily blocks, expiry, renewal semantics.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['api_key'], 'properties': {'api_key': {'type': 'string', 'description': 'The pool subscription key (sk-...)'}}, 'additionalProperties': False}
list_pools
List subscription pools
All active Unlimited pools: models served, per-block USDC price for 30 days, coarse availability. Blocks are 8h daily windows (UTC); reserving all blocks = 24/7. No auth required.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
