MCPHub is a self-hosted gateway that connects and manages multiple MCP servers, which provide tools, prompts, and resources to AI applications. Users organize servers into groups, control access, monitor activity and health, and expose stable endpoints to clients such as Claude Code, Cursor, and OpenWebUI; the catalogue entries operate within this MCP environment.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00187 |
| Opus 5 | $0.00000 | $0.00093 |
| Sonnet 5 | $0.00000 | $0.00037 |
| Haiku 4.5 | $0.00000 | $0.00019 |
Grade A, and why
typescript-and-frontend scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
TypeScript and frontend conventions
- Use
.jsextensions for relative ESM imports, including in TypeScript files. - Keep TypeScript strict; narrow types or define shared types instead of using
anyas a workaround. - Write code comments in English.
- Follow the repository formatter: two-space indentation and single quotes. Use the flat eslint.config.mjs ESLint configuration.
- Name services and DAOs with
ServiceandDaosuffixes. - Name React components and their files in
PascalCase; name utility modules incamelCase. - Put shared types in src/types/ instead of redefining DTOs locally.
- When adding a translation key, add it to all four locale files:
locales/en.json,locales/fr.json,locales/tr.json, andlocales/zh.json.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

typescript-and-frontend is an agent published in the GitHub repository samanhappy/mcphub (2,368 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 187 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-02.
