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
- No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. See how to fix → View diagnostics → Partial
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability67
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 914 tokens (~228/item across 4 items; 4 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 Management87
- Stability observed for 26 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 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

bra_size_at_brand Bra size at a brand ~241
Her size at one brand, in that brand's own labels (for example 32E at a UK-lettered brand where her US size is 32DDD), for its band and cup bras and for its letter-sized styles, each with a confidence badge and a reason. Use this when a shopper names a brand. If the brand doesn't carry her size, the answer says so and why (for example its bands start at 34, or its cups stop at DD) and names the closest size it makes (closest_made); pass that on rather than guessing. Use list_bra_brands if the brand isn't found.
| Name | Type | Req | Description |
|---|---|---|---|
| brand | string | yes | A brand name as shoppers write it (aliases accepted, any case), or an id from the brand list. |
| bust | number | yes | Around the fullest part of the bust, the tape flat and not pressing in. Decimals allowed. |
| underbust | number | yes | Snug around the ribcage, just under the bust, after breathing out. Decimals allowed. |
| unit | string | – | The unit both measurements are in: inches (in) or centimeters (cm). |
No output schema declared.
No examples provided.
bra_size_from_measurements Bra size from measurements ~190
Her bra size from her underbust and bust measurements (inches or cm, decimals allowed): her base US size, sister sizes one band each way, the UK size, EU and French sizes where their tables give the whole size, and the usual letter size (S/M/L). Use this when a shopper gives her measurements and wants her size in general. The answer includes a confidence badge and a reason: pass both on with the size. If the measurements are refused, tell her the reason given.
| Name | Type | Req | Description |
|---|---|---|---|
| bust | number | yes | Around the fullest part of the bust, the tape flat and not pressing in. Decimals allowed. |
| underbust | number | yes | Snug around the ribcage, just under the bust, after breathing out. Decimals allowed. |
| unit | string | – | The unit both measurements are in: inches (in) or centimeters (cm). |
No output schema declared.
No examples provided.
list_bra_brands Brands Measured Size knows ~101
The brands Measured Size has researched, with their other names, whether they sell band and cup sizes or letter sizes, their cup letters, band and cup ranges, whether their own letter chart is on file, and when their record was last researched. Use it to find a brand's name before the other tools, or to say which brands are covered.
| Name | Type | Req | Description |
|---|---|---|---|
| q | string | – | Optional: only brands whose name or an alias contains this text. |
No output schema declared.
No examples provided.
translate_bra_size Translate a bra size between brands ~157
Translate a band and cup size she wears at one brand (for example 34DD at Wacoal) into another brand's label, through Measured Size's base size. Use this only when the shopper has no measurements; measurements give a better answer. Translated sizes are rated no higher than Good Match: tell her so. It refuses letter sizes (S/M/L), labels the first brand's record doesn't give, and brands that sell letter sizes only, with the reason.
| Name | Type | Req | Description |
|---|---|---|---|
| from_brand | string | yes | The brand whose size she knows. |
| size | string | yes | Her band and cup size at from_brand, as that brand labels it. |
| to_brand | string | yes | The brand to translate the size into. |
No output schema declared.

How do I install the Measured Size MCP server?
Measured Size is a hosted endpoint at https://api.measuredsize.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Measured Size MCP server?
Measured Size is an MCP server listed in the public MCP registry as com.measuredsize/fit. Bra sizes from measurements, in each brand's own labels, with the confidence behind each. This page covers its hosted endpoint (https://api.measuredsize.com/mcp).
Is the Measured Size MCP server safe to use?
Measured Size scores 77 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 Measured Size MCP server expose?
Measured Size exposes 4 tools: bra_size_from_measurements, bra_size_at_brand, translate_bra_size, list_bra_brands. Their descriptions and schemas cost roughly 689 tokens of context every time the server is loaded.
Does the Measured Size MCP server require authentication?
No. We connected to Measured Size without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Measured Size MCP server still maintained?
Measured Size is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What did VerifyMCP test on the Measured Size MCP server?
VerifyMCP ran 12 checks on Measured Size, covering TLS certificate, Authorization, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about Measured Size: HTTPS. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
