What Amimica is

Amimica is a free, offline tool for finding repeated code across repositories. Its hybrid detection covers exact copies, renamed fragments, near-duplicates, and recurring patterns. The project describes its operation as deterministic and offers two ways to use it: a standalone command-line interface or an MCP server for Claude Code, VS Code, and other compatible clients. The CLI can return text or JSON, including output written to a file, and offers controls for clone scores and sizes, normalization, test-file handling, caching, and analysis depth. Project or global YAML files can store settings, with environment variables available to override them. Through stdio, the MCP server can scan a repository, list and explain findings, and compare source regions. Scan data stays in memory only for that server session and is discarded when it stops. The README lists Go, JavaScript, TypeScript, Ruby, Objective-C, and C# support. Amimica is MIT-licensed; building from source requires Go 1.25 or later. Its findings are intended to inform a human’s decision about refactoring.

Who it suits

Amimica suits developers who want to locate repeated code in repositories and review findings before deciding whether to refactor. It offers CLI and MCP-server workflows, with self-hosted use.

What it does well

Free plan and MIT license.
Detects exact, renamed, near-duplicate, and recurring clones.
CLI supports text, JSON, and file output.
Configurable thresholds, test handling, and analysis depth.
MCP tools explain findings and compare source regions.

What to know first

Building from source requires Go 1.25 or later.
MCP scan results disappear when the server stops.
No release assets are listed on the repository page.

Limits

Building and installing the documented source requires Go 1.25 or later. MCP scan results exist only in memory for the current server session and are discarded when it stops.

Getting started

Open the Amimica GitHub repository
Clone the project with Git
Install Go 1.25 or later
Build the tool from source
Install the binary to GOPATH/bin
Run the CLI or configure the MCP server over stdio

Verdict

Amimica provides configurable repository clone detection through a CLI or MCP server, with results meant to support human review. Its offline operation and session-only MCP results may matter when choosing how to run it.

Questions

Is Amimica free?

Yes. It is described as a free tool with a free plan and is distributed under the MIT license.

Which languages can it scan?

The README lists Go, JavaScript, TypeScript, Ruby, Objective-C, and C# support.

How can I use Amimica?

You can run the standalone CLI or use the MCP server with Claude Code, VS Code, and other MCP-compatible clients through stdio.

What output does the CLI provide?

The CLI can print text or JSON results and can write results to a file.

Can I configure clone detection?

Yes. Settings include clone score and size thresholds, normalization, test-file handling, caching, and thorough-analysis options. YAML files and environment variables can supply configuration.

What happens to MCP scan results?

Results are held in memory for the server session and disappear when the server stops.
