Manages bidirectional connections to MCP servers using an adapter pattern that abstracts both StdIO (local subprocess) and SSE (remote HTTP) transport layers. The MCPAdapt class acts as a context manager that establishes connections, negotiates protocol handshakes, maintains connection state, and gracefully closes resources. Supports both synchronous and asynchronous operation patterns through separate code paths, enabling integration with frameworks that require specific concurrency models.
Unique: Abstracts MCP transport layer (StdIO vs SSE) behind a unified context manager interface, eliminating boilerplate for subprocess management and HTTP connection handling. Uses jsonref library to resolve JSON schema $ref pointers, enabling proper tool schema validation across different MCP server implementations.
vs alternatives: Simpler than raw mcp library usage because it handles transport negotiation and resource cleanup automatically; more flexible than framework-specific integrations because it decouples server connectivity from framework adaptation.
Implements a ToolAdapter interface that defines abstract methods for converting MCP tool specifications (JSON schemas with input/output types) into framework-specific tool formats. Each supported framework (Smolagents, LangChain, CrewAI, Google GenAI) has a concrete adapter that translates MCP's canonical tool schema into that framework's expected tool definition structure, parameter validation rules, and execution signatures. The transformation preserves tool semantics while conforming to each framework's tool calling conventions.
Unique: Uses abstract ToolAdapter interface with concrete implementations per framework, enabling compile-time type safety while supporting runtime polymorphism. Leverages jsonref to resolve nested schema references, allowing MCP servers to use $ref pointers without requiring manual schema flattening.
vs alternatives: More maintainable than monolithic if-else framework detection because each adapter is isolated; more flexible than hardcoded transformations because new frameworks can be added by implementing the ToolAdapter interface.
Manages local MCP servers running as subprocesses using the StdIO (standard input/output) transport protocol. MCPAdapt spawns the server process, establishes bidirectional communication through stdin/stdout pipes, and handles process lifecycle events (startup, shutdown, crashes). The StdIO transport is the standard for local MCP servers, enabling integration with tools like Claude Desktop and local development environments.
Unique: Abstracts subprocess management and StdIO pipe handling, eliminating boilerplate for process creation, signal handling, and pipe management. Uses mcp library's native StdIO transport rather than implementing custom serialization.
vs alternatives: Simpler than manual subprocess management because it handles process lifecycle automatically; more reliable than raw pipe communication because it uses MCP's protocol-aware transport.
Connects to remote MCP servers using the Server-Sent Events (SSE) HTTP transport protocol, enabling integration with cloud-hosted or network-accessible MCP servers. MCPAdapt establishes HTTP connections to the server endpoint, negotiates the MCP protocol over SSE, and maintains the connection for tool invocation. This enables integration with MCP servers that don't run locally, such as cloud services or remote development environments.
Unique: Implements SSE transport for MCP protocol, enabling HTTP-based connectivity to remote servers without requiring WebSocket or gRPC. Uses mcp library's native SSE transport for protocol compliance.
vs alternatives: More scalable than local servers because it enables centralized server instances; more flexible than REST APIs because it uses MCP's standardized protocol for tool definition and invocation.
Enables connecting to multiple MCP servers simultaneously and aggregating their tool catalogs into a unified tool registry. The MCPAdapt class maintains a list of server connections and merges tool definitions from all servers, with built-in deduplication logic to handle tools with identical names across different servers. Tools are exposed as a flat list to the target framework, allowing agents to discover and invoke tools from any connected server without explicit server selection.
Unique: Implements server-agnostic tool aggregation that works across heterogeneous MCP server implementations without requiring servers to be aware of each other. Uses a simple list-based approach rather than a distributed registry, keeping the architecture lightweight and avoiding coordination overhead.
vs alternatives: Simpler than building a distributed tool registry because it centralizes aggregation in the client; more flexible than single-server approaches because it enables composition of specialized tool providers.
Provides dual code paths for synchronous and asynchronous execution, allowing MCPAdapt to integrate with frameworks that have different concurrency requirements. The library exposes both sync context managers and async context managers (mcptools), and framework adapters implement sync/async variants based on framework capabilities. This enables the same MCP server connections to be used in blocking (Smolagents, CrewAI) or non-blocking (LangChain, Google GenAI) frameworks without code duplication.
Unique: Implements separate sync and async code paths at the adapter level rather than using async-to-sync bridges, avoiding the performance overhead and complexity of wrapper libraries. Each framework adapter declares its concurrency capabilities explicitly, enabling static validation of sync/async compatibility.
vs alternatives: More efficient than using asyncio.run() or nest_asyncio() wrappers because it avoids event loop creation overhead; clearer than generic async-to-sync adapters because concurrency model is explicit in adapter class definition.
Executes tool calls by dispatching Remote Procedure Calls (RPCs) to the connected MCP server using the tool name and input parameters. When a framework invokes a tool, MCPAdapt marshals the parameters into the MCP protocol format, sends the call to the server, waits for the response, and returns the result to the framework. This decouples tool execution from the agent framework — the agent doesn't need to know whether tools are implemented locally or remotely on the MCP server.
Unique: Implements transparent RPC dispatch that preserves MCP protocol semantics while presenting a simple function-call interface to frameworks. Uses the mcp library's native RPC mechanisms rather than implementing custom serialization, ensuring compatibility with all MCP server implementations.
vs alternatives: Simpler than manual RPC implementation because it delegates to mcp library; more reliable than HTTP-based tool calling because it uses MCP's native protocol with built-in error handling.
Resolves JSON schema $ref pointers in MCP tool definitions using the jsonref library, enabling tools to use modular schema definitions with shared type definitions. Validates tool input parameters against the resolved schema before execution, catching type mismatches and missing required fields early. This ensures that tools receive well-formed inputs and that schema references don't cause runtime failures when tools are invoked.
Unique: Uses jsonref library to resolve $ref pointers at schema load time rather than at validation time, enabling efficient reuse of schema definitions across multiple tools. Integrates with pydantic for validation, leveraging pydantic's comprehensive JSON schema support.
vs alternatives: More efficient than runtime $ref resolution because it happens once at initialization; more robust than manual schema flattening because it preserves schema structure and enables circular reference detection.

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
