Anthropic Proxy
maxnowack · App
Anthropic Proxy is a local server that accepts requests in the Anthropic API format, converts them to the OpenAI format and passes them to OpenRouter, or to another OpenAI-compatible endpoint you set. You pick the models used for reasoning and for completions and the port it listens on, and can turn on debug logging. Setting Claude Code's base URL to the proxy lets Claude Code use it as its backend. It suits people who want Anthropic-format tools to reach other model providers.

Why it's useful
Tools that only speak the Anthropic API format can use models available through OpenRouter or other OpenAI-compatible services.
What you could do with it
- Point Claude Code at the proxy so its requests go to a model you choose on OpenRouter.
- Send Anthropic-format requests to another OpenAI-compatible server by setting a custom base URL.
- Run it on a port of your choice with debug logging on while you test a new setup.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Licence and provenance
- finding
- no LICENCE file at the root (.)
- Data handling disclosed
- finding
- no statement of what it reads, writes or sends (README.md)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
A proxy server that transforms Anthropic API requests to OpenAI format and sends it to openrouter.ai.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 1.3.0, the file with digest sha512-z63VrlWPHnuWlG726gtNMJjQTdwASXjiG9qgfwOpO3VuXj2zZVK+SGkThWaSGOOSzZB+vVLYWmXnKAxUEzZMvg==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y anthropic-proxy@1.3.0Pinned to 1.3.0, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
