b2-mcp vs mcp-gateway

b2-mcp: The Backblaze B2 MCP Server provides a Model Context Protocol interface, enabling AI clients like Claude to safely interact with Backblaze B2 Cloud Storage. It exposes 40 specialized tools for managing buckets, files, keys, Object Lock, and S3-compatible storage operations.; mcp-gateway: MCP Gateway enables AI assistants to securely access internal tools without exposing public endpoints, providing cryptographically secure, zero-trust connectivity. It aggregates multiple tool backends into a single secure endpoint, leveraging OpenZiti, zrok, and Agora for dark services that work through NATs and firewalls.

Features

b2-mcp logob2-mcp
01Provides 40 tools for Backblaze B2 and S3-compatible operations, including native B2 SDK, AWS S3 SDK, and custom analytics.
02Ensures safe operations through gated destructive actions and keeping durable B2 secrets out of the model's context.
03Features capability-aware registration, meaning an application key only accesses the tools it is authorized to use.
04Exposes read-only MCP resources for server configuration, capabilities, and bucket details without requiring tool calls.
05Supports flexible deployment options including local stdio, Docker, and various hosted HTTP environments.
mcp-gateway logomcp-gateway
01Zero-trust, cryptographically secure connectivity with no public attack surface.
02Aggregates diverse tool backends (stdio, zrok, Agora, HTTP/S) into a single secure endpoint.
03Operates through NATs and firewalls without requiring port forwarding.
04Provides isolated sessions for each connecting client, preventing shared state and cross-talk.
05Supports granular tool filtering and access control per backend.
