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 (quote_product). 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 Usability60
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 3492 tokens (~151/item across 23 items; 23 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 Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage78
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 24% of tool parameters carry a description.Partial
- 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 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 24 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 5 Nov 26 +1
- The server rewrote its instructions, which are the text every model session reads security
- Tool “get_product_quote” rewrote its description, which is the text the model reads security
- Tool “quote_product” rewrote its description, which is the text the model reads security
- Tool “send_letter” rewrote its description, which is the text the model reads security

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

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 →

preview_letter Preview Letter ~249
Render/inspect the exact letter or small postcard PDF and calculate its current price without sending, reserving credits or uploading artwork. Supply exactly one plain-text body or PDF. Covers First-Class, Certified, electronic return receipt, color, duplex, bulk recipients and coupon. Postcards default to included full color; letters default to black and white. Composed preview uses the first recipient. For a small postcard, the primary PDF remains the one-page print artwork; proof identifies a separate two-page PDF showing the approximate white print border and address side. Review that proof, but submit only the original artwork or body, never the proof. Recheck the final price before sending. Workspace authentication required.

quote_product Quote Product ~481
Hold a 36-hour expanded-product quote using a workspace key, print-ready PDF and 1–100 US recipients. Returns the exact expiration in expiresAt (UTC). Uploads artwork to DirectMailAmerica for live pricing; no charge or mailing. Each PDF page must match catalog dimensions; postcards require one landscape front artwork page. Two-sided postcard: pro_postcard_85x55, doubleSided:true, color:true, plus reverseMessage OR reverseArtworkBase64; the server assembles two pages. Maximum 25 MiB combined artwork. Staging quotes are demo estimates. Temporary pricing failures return a saved queued request with totalCents:null and a next-attempt time. Poll get_product_quote with the same ID; never recreate a queued request. A queue_held result needs review. Obtain approval of artwork, addresses and the final total after status becomes ready before sending.

save_cover_sheet Save Cover Sheet ~191
Create or update a reusable workspace cover sheet: name, heading, message, sans/serif font, heading/body sizes and alignment. An empty heading or message omits it. Read list_cover_sheets first; preview changes with render_cover_sheet. Use a new 64-character lowercase hexadecimal id and version:0 to create, or the existing id and current version to edit. A stale version fails; reread before saving again. Use defaultDesign to reset a draft. Maximum 25 designs. Validates fit and preserves fixed envelope address windows. No charge or mailing; does not attach the design to mail or change existing PDFs or saved quotes. Requires OAuth read/write and production workspace access, except the isolated reviewer workspace may save synthetic test designs. Workspace authentication required.

send_letter Send Letter ~508
Release the immutable quoteId from quote_letter using an existing authenticated workspace balance. Requires confirmed=true, approvedTotalCents matching the saved quote and one idempotencyKey after review of the exact saved PDF, addresses and options. Changed content requires a new quote and fresh approval. Immediately spends the approved amount and can buy postage. No guest payment, funding or cryptocurrency settlement. Insufficient balance sends nothing. Staging prevents postage but still debits the workspace balance. Safe failures before mailing authorization queue the approved order for automatic retry without another debit. Queued is not submitted. Reuse the same quoteId and key after interruption; uncertain sends require reconciliation. Tool contract: https://directmailamerica.com/agents/references/mcp-narrow.md
