Looking for an alternative to IAF Agent Bridge? Whether you need a different runtime environment, custom authentication support, or alternative API integrations in the Developer Tools ecosystem, we have cataloged and compared the top alternative MCP servers below.
IAF Agent Bridge MCP server lets Codex, Claude Code, or another stdio MCP host send work to Cursor Agent over ACP. It returns a session ID so the supervisor can continue the same Cursor conversation, while Cursor performs repository edits and command execution. Use it when an MCP host should supervise a local Cursor Agent session rather than implement the work itself. The bridge requires Node.js 20 or newer, an installed Cursor CLI, and completed Cursor authentication.
