Category Communication
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (call). See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability59
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1770 tokens (~221/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management47
- Stability observed for 14 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
call Call the human ~281
Ring the human's iPhone, read `question` aloud word for word, and return what they say back. It does not have to be a question: an update or a summary of the day ahead works too, up to 2000 characters (about two minutes of speech). Waits up to ~30s; if the result comes back status "ringing" or "in_call", follow up with poll_result. On a local client, read `to` from `~/.aiphone/config.json` → `user_number`; this hosted server cannot read that file itself. It is a Call Me app number, not a regular phone number. If missing, returns setup_required with the App Store link. Pass a previous session_token to stay in the same thread on their phone. keep_open=true makes it a conversation: after their answer the line stays up for `say` until you `hang_up`. `language` ("tr", "de", ...) is the language you are speaking; the call's own short lines follow it. Default English.
| Name | Type | Req | Description |
|---|---|---|---|
| from_label | string | – | – |
| keep_open | boolean | – | – |
| language | string | – | – |
| question | string | yes | – |
| session_token | – | – | – |
| to | – | – | – |
No output schema declared.
No examples provided.
hang_up Hang up ~71
End a call you placed. In a keep_open conversation `goodbye` is spoken first (e.g. "Thanks, I'll get on it."); leave it empty to just hang up.
| Name | Type | Req | Description |
|---|---|---|---|
| call_id | integer | yes | – |
| goodbye | string | – | – |
| session_token | string | yes | – |
No output schema declared.
No examples provided.
poll_result Get call result ~76
Check on a call that was still ringing or in progress. Waits up to ~25s for it to settle; returns the final status and transcript once the call ends, the human declines, or the ring times out ("missed").
| Name | Type | Req | Description |
|---|---|---|---|
| call_id | integer | yes | – |
| session_token | string | yes | – |
No output schema declared.
No examples provided.
say Say the next line ~151
In a call placed with keep_open=true, speak `text` to the human and return what they answer, in the same shape as `call`. Only after their previous answer is in. Waits up to ~30s; on "in_call", follow up with poll_result. "open": false means the call has ended. Pass `language` only to switch the language of the call's own lines; empty keeps it. Anything they said while you were thinking comes back as "said_while_waiting".
| Name | Type | Req | Description |
|---|---|---|---|
| call_id | integer | yes | – |
| language | string | – | – |
| session_token | string | yes | – |
| text | string | yes | – |
No output schema declared.
No examples provided.
set_thread_title Set thread title ~60
Name this session's conversation thread on the human's phone (e.g. the project or task you are working on). Shown as the thread title in the app.
| Name | Type | Req | Description |
|---|---|---|---|
| session_token | string | yes | – |
| title | string | yes | – |
No output schema declared.
No examples provided.
setup Set up Call Me ~25
Return first-setup instructions and a clickable App Store download link when no number is available.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
text Text the human ~112
Send a one-way text to the human's phone (push notification, no ring). On a local client, read `to` from `~/.aiphone/config.json` → `user_number`; this hosted server cannot read that file itself. If missing, returns setup_required with the App Store link. Pass a previous session_token to stay in the same thread.
| Name | Type | Req | Description |
|---|---|---|---|
| body | string | yes | – |
| from_label | string | – | – |
| session_token | – | – | – |
| to | – | – | – |
No output schema declared.
No examples provided.
wait_for_reply Wait for a text reply ~106
Wait for the human to send something back to this session — texts and voicemail transcripts arrive here. Long-polls up to wait_s (max 30s); returns {events, cursor}. Pass the returned cursor next time to only see new events. An empty events list just means nothing yet — poll again if you are still waiting.
| Name | Type | Req | Description |
|---|---|---|---|
| cursor | integer | – | – |
| session_token | string | yes | – |
| wait_s | integer | – | – |

How do I install the Call Me MCP server?
Call Me is a hosted endpoint at https://callmemcp.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Is the Call Me MCP server safe to use?
Call Me scores 65 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Call Me MCP server expose?
Call Me exposes 8 tools: setup, call, poll_result, say, hang_up, and 3 more. Their descriptions and schemas cost roughly 882 tokens of context every time the server is loaded.
Does the Call Me MCP server require authentication?
No. We connected to Call Me without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Call Me MCP server still maintained?
Call Me is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
