obfus.link — MCP Server
31 deterministic developer tools on a lean, machine-payable MCP endpoint.
The official MCP Registry manifest for obfus.link lives in
this repo (server.json).
Endpoint:
https://obfus.link/mcpRegistry name:
link.obfus/utility-gridTools: obfuscators, encoders, converters, generators, analyzers, validators (JSON→Zod, regex-from-examples, JWT hardener, curl→fetch, AES-256 link obfuscator, hashing/encoding, and more).
Why this one
Lean by design. Most MCP servers front-load every tool definition into your agent's context (~21k tokens here) on every turn. obfus.link advertises one search tool by default and discovers the rest on demand — ~98% less resident context. Reproduce it: obfus.link/why.
Deterministic, not generative. A tool call returns the same correct answer, byte-identical, every time — no retries, no drift.
Machine-payable. 50 free calls per IP, then a
402challenge an agent can complete on its own (MPP). Discovery is always free.

Add it to your agent
obfus.link is a remote (Streamable HTTP) MCP server. Most clients connect via the
mcp-remote bridge — for example, in claude_desktop_config.json:
{
"mcpServers": {
"obfus-link": {
"command": "npx",
"args": ["-y", "mcp-remote", "https://obfus.link/mcp"]
}
}
}Full onboarding (Cursor, SPT auth for paid use, the error contract): obfus.link/docs/mcp.
Try it without an agent
A zero-dependency, clone-and-run example (messy LLM JSON → clean, typed Zod schema in two deterministic calls) lives at subether-labs/obfus-link-demo.
