GlyphGuard finds hidden and deceptive Unicode in text: invisible characters (zero-width, soft hyphen, fillers), bidi controls used for Trojan Source attacks, Unicode tag characters (decoded, a prompt-injection smuggling channel), variation-selector runs, control characters, odd spaces, mixed-script words and lookalike letters (Cyrillic "а" posing as Latin "a"). Joiners in legitimate context (emoji ZWJ sequences, VS16, Persian/Arabic ZWNJ, Indic virama ZWJ/ZWNJ) are info only and kept by clean_text unless strict=true. Lone surrogates are flagged. Use scan_text before trusting pasted text, tool…

- Is glyphguard live?
- Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
- Is glyphguard free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does glyphguard have?
- 3 tools: compare_names, clean_text, scan_text.
- Is glyphguard safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid
Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
compare_names unknown 2h ago
Check whether a name, username, domain label or brand looks the same as any of up to 50 protected names (for example "pаypal" with a Cyrillic а vs "paypal"), using a UTS #39-style confusable skeleton (curated subset, case and accents ignored). Read-only. Same engine as GET /api/compare.
{ "type": "object", "required": [ "name", "targets" ], "properties": { "name": { "type": "string", "maxLength": 128, "minLength": 1, "description": "Name, username, domain label or brand to test." }, "targets": { "type": "array", "items": { "type": "string", "maxLength": 128, "minLength": 1 }, "maxItems": 50, "minItems": 1, "description": "1 to 50 protected names." } }, "additionalProperties": false }arguments 27 linesclean_text unknown 2h ago
Return the text with invisible characters, bidi controls, tag characters and control characters removed and unusual spaces turned into normal spaces. By default ZWJ/ZWNJ/VS16 are kept inside emoji sequences, between letters of joining scripts (Arabic, Persian) and after an Indic virama (keep_joiners=true); strict=true removes them everywhere. Optional: map lookalike letters to Latin (lookalikes) and apply NFKC normalisation (nfkc). Read-only. Same engine as GET /api/clean.
{ "type": "object", "required": [ "text" ], "properties": { "nfkc": { "type": "boolean", "default": false, "description": "Apply Unicode NFKC first (fullwidth and math letters → plain)." }, "text": { "type": "string", "maxLength": 2000, "minLength": 1, "description": "Text to inspect (up to 2000 UTF-16 code units)." }, "spaces": { "type": "boolean", "default": true, "description": "Turn unusual spaces into a normal space." }, "strict": { "type": "boolean", "default": false, "description": "Strict mode: remove every joiner and variation selector, even in emoji and Persian/Indic text (overrides keep_joiners)." }, "lookalikes": { "type": "boolean", "default": false, "description": "Map lookalike letters (e.g. Cyrillic а) to Latin. Changes legitimate non-Latin text too." }, "keep_joiners": { "type": "boolean", "default": true, "description": "Keep ZWJ/ZWNJ/VS16 where they are legitimate: emoji ZWJ sequences and VS16 emoji presentation, between letters of joining scripts (Arabic, Persian), and after an Indic virama. Joiners elsewhere are always removed." } }, "additionalProperties": false }arguments 40 linesscan_text unknown 2h ago
Find invisible characters, bidi controls (Trojan Source), hidden Unicode tag payloads (decoded), variation-selector runs, control characters, unusual spaces, mixed-script words and lookalike letters. ZWJ/ZWNJ/VS16 in legitimate context (emoji sequences, Persian/Arabic joining, Indic virama) are reported as info joiner_in_context and do not raise risk; elsewhere they stay medium. Lone surrogates are flagged. Returns a risk level (none/low/medium/high), counts, and findings with UTF-16 offsets and code points. Read-only. Same engine as GET /api/scan.
{ "type": "object", "required": [ "text" ], "properties": { "text": { "type": "string", "maxLength": 2000, "minLength": 1, "description": "Text to inspect (up to 2000 UTF-16 code units)." } }, "additionalProperties": false }arguments 15 lines
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idf21e87f024678e79.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/f21e87f024678e79/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
