What this server can do
5 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
get_messages(input)- List all SMS messages received in this session without consuming the OTP. Use this to inspect raw messages or check if an SMS arrived before calling wait_for_otp. Does NOT mark the OTP as consumed. Required: input.
list_numbers(agent_id)- List active sessions, optionally filtered by agent_id. Use this to check for leaked sessions or inspect what numbers are currently active in your account.
provision_number(input)- Lease a temporary programmable phone number for receiving SMS OTP codes. Returns the phone number (e164 format) and a session_id needed for all subsequent calls. The number is reserved for your session for ttl_seconds. Next step: use the returned `number` on your target service to trigger an SMS, then call `wait_for_otp` with the returned `session_id`. Required: input.
release_number(input)- Release a provisioned number back to the pool. Always call this when you are done with the session — even on error — to avoid consuming pool capacity unnecessarily. Required: input.
wait_for_otp(input)- Block until an SMS OTP arrives for this session, then return the code. Polls the AgentSIM API for up to `timeout_seconds`. Returns the OTP code and the message it was extracted from. If the OTP does not arrive in time, raises a ToolError with advice on retrying. Always call `release_number` after you have used the OTP. Required: input.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
| Signal | Value | What it measures | Window | Observed | Source |
|---|---|---|---|---|---|
| GitHub stars | 1 | Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality. | cumulative, all time | GitHub | |
| Last commit | 2026-06-17 | Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained. | point in time | GitHub | |
| Open issues | 0 | Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one. | as of fetch | GitHub | |
| Latest published version | 0.21.0 | Latest version string the maintainer published to the registry. | as of fetch | Model Context Protocol | |
| Registry record last updated | 2026-06-17 | When the registry record was last updated by its maintainer. | point in time | Model Context Protocol | |
| License | MIT | Licence GitHub detected in the repository. Detection can be wrong; the LICENSE file is authoritative. | as of fetch | GitHub | |
| First listed in the MCP Registry | 2026-06-17 | Date this server was first published to the official MCP Registry. Not a usage or quality measure. | point in time | Model Context Protocol | |
| repository status | active | The repository exists on GitHub and is not archived. This says nothing about how recently it was worked on. | as of fetch | GitHub | |
| mcp tools declared | 5 tools | Number of functions the server itself declared when asked to list them. This is what the server offers an agent, not a measure of how well any of them work. | as of probe | mcp.agentsim.dev | |
| mcp endpoint status | ok | The server listed 5 functions when asked. | as of probe | mcp.agentsim.dev |

These share tags the maintainers applied themselves, such as otp, phone-verification, sms. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.
This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
