Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
Chroma Package SearchCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Obtain an API key from Chroma, then invoke the server’s three tools: package_search_grep (regex grep), package_search_hybrid (semantic + regex), and package_search_read_file (read specific line ranges). The API key can be acquired at https://trychroma.com/package-search.
package_search_hybrid
## Description Searches package source code using semantic understanding AND optionally regex patterns. This allows for hybrid search, allowing for prefiltering with regex, and semantic ranking. Required Args: "registry", "package_name", "semantic_queries" Optional Args: "version", "filename_sha256", "pattern", "language" Best for: Understanding how packages implement specific features, finding usage patterns, or exploring code structure.
package_search_read_file
## Description Reads exact lines from a source file of a public package. Useful for fetching specific code regions by line range. Required Args: "registry", "package_name", "filename_sha256", "start_line", "end_line" Optional Args: "version" Best for: Inspecting exact code snippets when you already know the file and line numbers. Max 200 lines.
package_search_grep
## Description Executes a grep over the source code of a public package. This tool is useful for deterministically finding code in a package using regex. Use this tool before implementing solutions that use external packages. The regex pattern should be restrictive enough to only match code you're looking for, to limit overfetching. Required Args: "registry", "package_name", "pattern" Optional Args: "version", "language", "filename_sha256", "a", "b", "c", "head_limit", "output_mode" Best for: Deterministic code search, finding specific code patterns, or exploring code structure.

}The Package Search MCP Server adds ground truth context about code packages to AI agents. Our research demonstrates that by exposing the source code of a project's dependencies to a model, we improve its performance on coding tasks and reduce its potential for hallucination. Package Search achieves this by exposing regex and semantic query capabilities over popular open source code packages.
package_search_grep
Executes a grep over the source code of a public package. This tool is useful for deterministically finding code in a package using regex.
package_search_hybrid
Searches package source code using semantic understanding AND optionally regex patterns.
This allows for hybrid search, allowing for prefiltering with regex, and semantic ranking.
package_search_read_file
Reads exact lines from a source file of a public package. Useful for fetching specific code regions by line range.
Getting an API Key
Create a Chroma account and get an API key at https://trychroma.com/package-search. Receive $5 worth of free credits, roughly 1,000 semantic queries.
