Category Communication
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security50
- Malware scan not yet available for this package.Unverified
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 32 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to tmailor-com/tmailor-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass

- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability72
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1120 tokens (~140/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

Stability & Change Management10
- Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.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 →

read_message Read one message ~209
Read one message: `otp`, `codes`, `links` and the body. Marks the message as read. `body_format` picks the body: "text" (plain text, default), "html" (the raw HTML exactly as received) or "both". `has_html` says whether the message has an HTML part.
| Name | Type | Req | Description |
|---|---|---|---|
| body_format | string | – | Which body to return: "text" (plain text, default), "html" (the raw HTML exactly as received; falls back to text when the message has no HTML part) or "both". |

wait_for_message Wait for an email (OTP, verification link) ~305
Return the newest UNREAD message matching the filters, or wait until one arrives. The result includes `otp` (the one-time code found in the message, or null), `codes`, `links` and the body chosen by `body_format` (plain text by default; "html" or "both" for the raw HTML). Returning a message marks it as read, so the next call waits for the next one. If nothing arrives in time, `status` is "timeout": call again if the email may still come (for example the sign-up was just submitted).
| Name | Type | Req | Description |
|---|---|---|---|
| body_format | string | – | Which body to return: "text" (plain text, default), "html" (the raw HTML exactly as received; falls back to text when the message has no HTML part) or "both". |
