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 Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 7 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability76
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 803 tokens (~114/item across 7 items; 7 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "send_fax" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail

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 →
check_fax_status ~54
Check the delivery status of a previously sent fax using its job_id. No authentication required — the job_id is the unforgeable token.
| Name | Type | Req | Description |
|---|---|---|---|
| job_id | string | yes | The job ID returned by send_fax |
No output schema declared.
No examples provided.
get_account_balance ~23
Get the current page balance and dollar amount balance for the authenticated account.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_sent_faxes ~83
List faxes previously sent by the authenticated account (most recent first). Includes faxes sent via MCP, REST API, and the prepaid web form. Free anonymous sends are not included.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max records to return (1-100, default 20) |
| offset | integer | – | Skip first N records for pagination (default 0) |
No output schema declared.

list_supported_formats ~20
List all supported file formats that can be faxed.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
purchase_credits ~200
Start a prepaid credit purchase. If the request is authenticated, credits will be loaded into the authenticated account after PayPal payment. If the request is not authenticated, provide email and name to create a new prepaid account (or load credits into an existing one with the same email). Returns a PayPal payment URL the user must visit to complete the purchase.
| Name | Type | Req | Description |
|---|---|---|---|

send_fax ~92
Send a fax to a US or Canada phone number. Accepts PDF, DOC, DOCX, JPG, JPEG, TXT files (max 10) as base64-encoded content.
| Name | Type | Req | Description |
|---|---|---|---|
| fax_number | string | yes | Destination fax number (10 digits, US or Canada) |

send_free_fax ~331
Send a free fax to a US or Canada number (no account required). Limited to 3 pages total and 2 sends per email/IP per day. Returns a job_id immediately, but the fax does NOT send until the sender clicks a confirmation link emailed to sender_email. The daily-limit check happens at click time, not at submission — a submitted fax may still be rejected if the limit is hit by then; the agent can detect this by calling check_fax_status after the user reports clicking the link. If the document exceeds the free page limit, the response will suggest using purchase_credits to buy a prepaid account.
| Name | Type | Req | Description |
|---|---|---|---|
| cover_sheet | boolean | – | Include cover sheet (default true). |
| fax_number | string | yes | Destination fax number (10 digits, US or Canada). |
| files | array | – | Up to 3 files. Each must be base64-encoded. Free faxes are limited to 3 pages total across text + files. |
| receiver_company | string | – | Receiver's company (optional). |
| receiver_name | string | yes | Receiver's name (required). |
| sender_company | string | – | Sender's company (optional). |
| sender_email | string | yes | Sender's email address. A confirmation link will be sent here; the fax does NOT actually send until the user clicks that link. |
| sender_fax | string | – | Sender's fax number (optional). |
| sender_name | string | yes | Sender's name (required). |
| subject | string | – | Subject line (optional). |
| text | string | – | Fax body text. Either text or files must be provided. |
