- Version: `1.0.0`

## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-16.

- **Endpoint Security**: 92/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 5511 tokens (~69/item across 79 items; 79 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 91/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 73% of tool parameters carry a description.
- **Tool Safety**: 98/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 9 of 10 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "call2me_get_auto_charge" implies "charge" and declares readOnlyHint instead, contradicting what its own name says it does.
  - An AI judge read all 80 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Common questions

### What is the Call2Me MCP server?

Call2Me is an MCP server listed in the public MCP registry as app.call2me/mcp. Place real phone calls, read transcripts, run a live interpreter and buy numbers. This page covers its hosted endpoint (https://mcp.call2me.app/mcp).

### Is the Call2Me MCP server safe to use?

Call2Me scores 84 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 Call2Me MCP server expose?

Call2Me exposes 79 tools: call2me_profile, call2me_list_agents, call2me_get_agent, call2me_list_calls, call2me_get_call, and 74 more. Their descriptions and schemas cost roughly 5,423 tokens of context every time the server is loaded.

### Does the Call2Me MCP server require authentication?

Yes. Call2Me asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the Call2Me MCP server still maintained?

Call2Me is still listed as active in the MCP registry. We last reached this channel on 16 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
