Chroma Package Search
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.
