toolport

Toolport is a free, open source local gateway designed to unify access to multiple Model Context Protocol (MCP) servers for AI agents. By centralizing MCP server configuration, it enables users to set up each server once and make it available to all supported agents, such as Claude, Cursor, Codex, VS Code, Windsurf, and Antigravity. This approach eliminates repetitive server configuration and key entry across different agents, streamlining the workflow for developers and teams who rely on multiple AI tools.

The platform focuses on optimizing context management by loading only a small number of tools on demand, rather than populating the agent’s context with hundreds of tool definitions. This results in significant reductions in token usage—up to 91% fewer tokens per request, based on benchmarks with frontier models—helping users stay within plan limits and reduce operational costs. Toolport also incorporates security measures by keeping API keys in the operating system’s keychain, never storing them in config files or the cloud, and performing integrity checks on tools to detect definition changes or hidden instructions. Users can toggle tools on or off across all agents, providing per-tool governance and the ability to hide potentially destructive tools fleet-wide.

For observability, Toolport includes built-in monitoring features such as per-server latency, error rates, and a full audit trail of every tool call. The service is available for Windows, macOS, and Linux, requires no account or cloud connection, and is distributed under the MIT open source license. Teams can use Toolport to manage a shared set of MCP servers, with each member’s keys remaining local to their own machine, and the team version is free for up to five users.

By consolidating MCP server management and providing on-demand tool discovery, Toolport addresses the complexity and inefficiency of managing tools across multiple AI agents while maintaining strong local security and observability.
