AI tool
ForAgent
ForAgent lets coding agents communicate through private numbers that require human approval for each call. It is for developers who coordinate separate agents working on different parts of a codebase.
About ForAgent
ForAgent assigns private phone numbers to AI coding agents so they can call each other. The tool routes these calls through a human approval step - no connection happens until a person picks up. It works on local machines or between teammates, with calls handled in the ForAgent app or directly inside an AI environment via a plugin.
Review
ForAgent tackles a specific friction point: moving context between two AI agents that can't directly communicate. Instead of a person copying output from one agent and pasting it into another, the agents connect through numbered channels. The per-call human pickup requirement means no agent-to-agent connection occurs without explicit approval.
Key Features
- Private numbers for each agent (formatted as @12, @29, etc.) that agents use to initiate calls
- Per-call human pickup approval - a person must accept the connection before agents exchange information
- In-app call handling alongside a plugin that lets agents manage calls from within an AI interface
- Free calls between your own numbers; calls to other accounts count toward a monthly limit
- Agents connect only for the duration of a single call, with no persistent open line
Pricing and Value
The Free plan includes 30 calls per month with other accounts. Calls placed between your own numbers don't count against this limit. Pricing for plans beyond the Free tier is not yet defined on the product page.
Pros
- Reduces manual copy-paste between agents working on separate parts of a codebase
- Human-in-the-loop approval prevents unsupervised agent-to-agent communication
- Works across different machines, so a teammate's agent can call yours without shared infrastructure
- Plugin integration means agents handle calls without leaving the AI workspace
- Free tier lets you test the per-call security model without payment
Cons
- Requires a human to approve every call, which adds a step to automated workflows
- The 30-call monthly cap on the Free plan may run out quickly in active multi-agent setups
- Not well suited for teams that want fully autonomous agent collaboration with no manual intervention
ForAgent fits scenarios where a developer runs multiple coding agents in parallel and needs structured handoffs between them - backend to frontend, or local agent to a teammate's agent. The required human pickup makes it easier to audit what agents share, though it also means the workflow never goes fully hands-off. If your setup already handles agent communication through shared files or a central coordinator, the added approval step might slow things down rather than help.
