Exposes payment operations as standardized MCP (Model Context Protocol) tools that AI agents like Claude can discover and invoke through a FastMCP server framework. The server implements a request-response pattern where agents call tools with structured parameters, the FastMCP framework routes them to handler functions, and responses are serialized back to the agent. This enables AI agents to treat payment operations as first-class capabilities without custom integration code.
Unique: Uses FastMCP framework to expose payment tools with automatic schema generation and discovery, enabling AI agents to understand and invoke payment operations without hardcoded integration code. The MCP protocol provides a standardized interface that works across multiple AI platforms rather than being tied to a single LLM provider.
vs alternatives: Simpler than building custom REST API integrations for each AI platform because MCP handles protocol negotiation, schema discovery, and tool invocation standardization automatically.
Implements a balance() tool that queries the Fewsats payment platform via the Fewsats client library to fetch current wallet balance and account information. The tool makes an authenticated API call using the FEWSATS_API_KEY, receives structured balance data from the backend, and returns it to the agent. This enables agents to check available funds before initiating payments or to report account status.
Unique: Directly wraps the Fewsats client library's balance endpoint, providing agents with real-time account state without intermediate caching or transformation layers. The tool is stateless and always returns current data from the Fewsats backend.
vs alternatives: More reliable than client-side balance tracking because it always queries the authoritative source (Fewsats backend) rather than relying on cached or estimated values.
Exposes a payment_methods() tool that queries the Fewsats platform to retrieve all available payment methods supported by the user's account. The tool calls the Fewsats client library to fetch the list of payment methods, which may include credit cards, bank transfers, cryptocurrency, or other payment rails. Agents can use this to understand what payment options are available before initiating a transaction.
Unique: Provides a simple enumeration interface to the Fewsats payment method registry, allowing agents to discover available payment rails without needing to know the Fewsats API structure. The tool abstracts away authentication and API versioning details.
vs alternatives: Simpler than querying the Fewsats API directly because the MCP tool handles authentication and response parsing automatically, allowing agents to focus on payment logic.
Implements a pay_offer() tool that processes payments by accepting an offer_id and optional l402_offer parameter, then calling the Fewsats client library to execute the payment. The tool supports the L402 protocol (Lightning-402 HTTP authentication), which allows agents to handle payment challenges and proofs in a standardized way. The tool returns payment status and transaction details after execution.
Unique: Integrates L402 HTTP authentication protocol support, enabling agents to handle payment challenges and generate cryptographic proofs in a standardized way. This is distinct from simple payment APIs because it supports the full L402 challenge-response flow for metered access and micropayments.
vs alternatives: More flexible than fixed-price payment APIs because L402 support allows dynamic pricing, pay-per-use models, and standardized payment challenges that work across multiple service providers.
Exposes a payment_info() tool that retrieves detailed information about a specific payment transaction using a payment ID (pid). The tool queries the Fewsats backend via the client library to fetch transaction status, amount, timestamp, payment method used, and other metadata. Agents can use this to verify payment completion, track transaction history, or handle payment failures.
Unique: Provides a lookup interface to the Fewsats transaction ledger, allowing agents to retrieve full transaction details by payment ID without needing to maintain local transaction state. The tool abstracts away API authentication and response parsing.
vs alternatives: More reliable than client-side transaction tracking because it queries the authoritative Fewsats ledger, ensuring agents always have current and accurate payment status.
Implements a billing_info() tool that queries the Fewsats platform to retrieve billing-related account information such as billing address, payment history summary, account status, and subscription details. The tool calls the Fewsats client library to fetch this metadata and returns it as structured JSON. Agents can use this to understand account configuration, verify billing status, or generate billing reports.
Unique: Aggregates billing-related account metadata from the Fewsats platform into a single tool call, allowing agents to access account configuration without making multiple API calls. The tool provides a simplified interface to complex billing data structures.
vs alternatives: Simpler than querying the Fewsats API directly because the MCP tool abstracts away authentication, response parsing, and data transformation, allowing agents to focus on billing logic.
Manages authentication to the Fewsats payment platform through environment variable-based API key injection. The server reads FEWSATS_API_KEY from the environment at startup and passes it to the Fewsats client library, which uses it to authenticate all API requests. This approach keeps credentials out of code and tool parameters, reducing the risk of accidental exposure. The authentication is transparent to agents — they invoke tools without handling credentials directly.
Unique: Uses environment variable-based API key injection to keep credentials out of agent-visible parameters and logs, reducing the attack surface for credential exposure. The Fewsats client library handles the actual authentication, while the MCP server manages key lifecycle.
vs alternatives: More secure than passing API keys as tool parameters because credentials never appear in agent prompts, logs, or tool invocation traces, reducing the risk of accidental exposure in multi-tenant or logged environments.
Builds on the FastMCP framework to automatically register payment tools with standardized schemas, enabling AI agents to discover tool signatures and invoke them through the MCP protocol. The server creates a FastMCP instance, decorates tool functions with MCP metadata, and exposes them through a standardized interface. FastMCP handles protocol negotiation, schema validation, and request routing automatically, abstracting away MCP protocol complexity from tool implementations.
Unique: Leverages FastMCP's automatic schema generation and protocol handling to reduce boilerplate code for tool registration. The framework automatically validates parameters, handles errors, and formats responses according to MCP specifications without explicit implementation in each tool.
vs alternatives: Simpler than implementing MCP protocol directly because FastMCP handles schema generation, request routing, and error handling automatically, allowing developers to focus on business logic rather than protocol details.

Performs semantic similarity searches on vector embeddings stored in Supabase PostgreSQL using pgvector extension, translating natural language queries into embedding vectors and executing cosine/L2 distance searches. Integrates with embedding providers (OpenAI, Cohere) or uses pre-computed embeddings, enabling agents to retrieve semantically similar documents or records without full-text search limitations.
Unique: Integrates pgvector directly into MCP tools with automatic embedding generation and distance calculation, enabling agents to perform semantic search without managing separate vector database infrastructure
vs alternatives: More efficient than external vector databases (Pinecone, Weaviate) for Supabase users because it colocates embeddings with relational data, reducing network latency and simplifying data synchronization
Exposes Supabase database schema information through MCP tools, allowing agents to discover table structures, column types, constraints, and relationships without manual schema documentation. Queries PostgreSQL information_schema and Supabase metadata tables to dynamically generate schema descriptions, enabling agents to construct valid queries and understand data relationships.
Unique: Queries Supabase's PostgreSQL information_schema directly through MCP tools, enabling agents to dynamically discover and adapt to database schemas without pre-configured schema definitions
vs alternatives: More flexible than static schema definitions because it reflects live database state, including recent migrations or schema changes
Enforces Supabase Row-Level Security policies within agent queries, ensuring that agents can only access rows permitted by RLS rules defined in the database. Evaluates policies based on authenticated user context (JWT claims, user ID) and applies WHERE clause filters automatically, preventing unauthorized data access at the database layer rather than application layer.
Unique: Delegates authorization enforcement to PostgreSQL RLS policies rather than implementing authorization in agent code, ensuring that data access rules are centralized and cannot be bypassed by agent logic
vs alternatives: More secure than application-level authorization because RLS is enforced at the database layer, preventing accidental data leaks even if agent code has bugs
