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 check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (commsharbor_email_mailbox_update). See how to fix → View diagnostics → Fail
- 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 Usability81
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 4340 tokens (~114/item across 38 items; 38 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 Management6
- Stability check failed: schema churn in the 30 days we've observed: 130 tool removals, 0 breaking changes, 0 auth/transport breaks, 29 additions. See how to fix → Fail
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 Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 39 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; 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 →

commsharbor_brazil_email_report Commsharbor brazil email report ~181
Read the monthly Brazil email security report: how many domains of city halls, state and federal government, banks and listed companies reject fake email (DMARC p=reject) and how they end SPF. Totals only, public DNS. Free, no account. Public DNS only, read once a month. The sample is built from Brazil's open company registry (Receita Federal, the email of each active head office) and the CVM register of listed companies. Only totals: no domain is listed. A share is `count / (com_mx - dmarc.nao_lido)`; domains without MX are left out. Only the DMARC policy classifies; SPF is counted but does not change the class. `percent` rounds each group to 100 by the largest remainder, the same rule as the page.

No output schema declared.
No examples provided.
commsharbor_me Commsharbor me ~70
Read the current account profile and platform role. `user.id` is the shared-account ID. Organizations are not listed here: they live in the shared account, which does not list them inside products yet — open a workspace by its ID with `GET /api/organizations/{organization_id}`.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
commsharbor_organization_get Commsharbor organization get ~83
Open an organization by id: name, your role and the CommsHarbor plan. This is how a workspace is opened. Name and role come from the shared account (null with an organization API key, which carries neither); the plan is the organization's global entitlement in CommsHarbor.
| Name | Type | Req | Description |
|---|---|---|---|
| organization_id | string | yes | Active organization ID |
No output schema declared.
No examples provided.
commsharbor_platform_context Commsharbor platform context ~34

No examples provided.
get_api_x402_email_check Get API X402 email check ~223
Checks the email security of a domain for an agent, paid per call: SPF, DKIM, DMARC, MX and a score, with no account. The check of `GET /api/email-check`, sold per call to agents, with no account and without the 30 free checks per day before. A request without payment gets the 402 with the price; a paid one gets the audit in the same response, with the payment in `cobranca`. DKIM is looked up in common selectors only; `incomplete: true` means a DNS answer failed. A refused domain, the hourly limit of the service and a failed DNS lookup are not charged. DNS lookups, record parsing and assembling the domain's email-policy findings. DKIM checks common selectors only. Inspect incomplete and unread. A score does not prove inbox placement, stop every phishing attack or verify the contents of a mailbox.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | Public domain to check, such as example.com. A subdomain or URL is reduced to its registrable domain. |
No output schema declared.
