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 Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not yet verified: we couldn't confirm whether this endpoint requires it. View diagnostics → Unverified
- HTTPS check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- 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 & Reachability0
- Transport check failed: declared streamable-http, but the endpoint returned HTTP 500. See how to fix → View diagnostics → Fail
Schema Quality & AI Usability0
- Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.Unverified
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage0
- Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified
Tool Safety0
- Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.Unverified

Unverified: 5 categories
Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

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 →

How do I install the textkit (paid) MCP server?
textkit (paid) is a hosted endpoint at https://textkit.johnaio281.workers.dev/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 textkit (paid) MCP server?
textkit (paid) is an MCP server listed in the public MCP registry as dev.workers.johnaio281.textkit/textkit. Text and Unicode utilities for agents: homoglyphs, scripts, slugify, entropy, dates. Paid via x402. This page covers its hosted endpoint (https://textkit.johnaio281.workers.dev/mcp).
Is the textkit (paid) MCP server safe to use?
textkit (paid) scores 18 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 textkit (paid) MCP server expose?
textkit (paid) exposes 12 tools: tk_homoglyphFold, tk_scriptDetect, tk_unicodeNormalize, tk_graphemeCount, tk_describeDate, and 7 more. Their descriptions and schemas cost roughly 617 tokens of context every time the server is loaded.
Does the textkit (paid) MCP server require authentication?
Its publisher declares no required credentials for textkit (paid). We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.
Is the textkit (paid) MCP server still maintained?
textkit (paid) is still listed as active in the MCP registry. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
