Fossick MCP server

Read from the package source without running it. The installed server may list more.

• find_symbol

  Goto-definition: find where a symbol is defined in one repo or across all of GitHub.

• get_file

  Read file content from one file in a GitHub repository. Returns full file with line numbers, supports line range slicing (start_line/end_line) and substring/regex match filtering with context lines. Truncates files over 500 lines unless a range or match is specified. Use after locating a file via search_code, find_symbol, or repo_tree.

• list_tags

  List tags or releases for one repository. Default mode returns lightweight tag names with commit SHAs. Release mode (releases=true) returns full release objects including tag name, title, changelog body, publish date, and attached assets. Use to check a library's freshness (is it actively maintained?), find the current version to pin against, or pick a specific release to read files at via get_fil

• repo_tree

  View the file tree of a GitHub repository or subdirectory. Recursive listing with depth control (1-3 levels), glob pattern filtering (e.g. *.py), and optional file sizes. Automatically filters noise directories (node_modules, __pycache__, .venv, dist, etc.). Use to understand project layout and discover key files before reading them with get_file.

• search_packages

  Search for a package on PyPI or npm (not GitHub — does not use GitHub API or rate limits). PyPI: exact-match lookup returning version, description, license, homepage, and GitHub URL. npm: text search returning multiple results with links. Use for looking up package metadata and versions — chain with search_repos to explore the source repository.
