name	mcp-github
description	Call GitHub MCP tools via mcporter CLI — 40 tools for PRs, issues, repos, code search, releases, and more. Use for: 'search code across repos', 'read files from another branch', 'review PR diff', 'cross-repo queries', 'push files to remote'. Requires GITHUB_TOKEN env var.

Call GitHub MCP tools through the mcporter CLI. 40 structured tools for pull requests, issues, repositories, code search, releases, users, and teams. Use this for cross-repo operations, structured data retrieval, and capabilities the local `gh` CLI doesn't offer (semantic code search, file content by ref, batch operations). Requires `GITHUB_TOKEN` env var (set in ~/.zshrc).

When to Use This vs gh CLI

Task	Use	Why
Local repo PRs (create, merge, view)	gh	Already authenticated for current repo
Read files from any repo/branch/tag	mcporter	get_file_contents with ref param
Search code across GitHub	mcporter	search_code with language/org/path filters
Get PR diff as structured data	mcporter	pull_request_read(method: "get_diff")
Cross-repo issue/PR queries	mcporter	No need to clone or switch repos
Create/push files to remote repos	mcporter	push_files for multi-file commits
Review PRs programmatically	mcporter	pull_request_review_write with line comments
Repo/org-level search	mcporter	search_repositories, search_users
Quick local checks (status, log, diff)	gh / git	Faster, no network call

Call Syntax

# Colon-delimited (shell-friendly, best for simple args)
mcporter call github.TOOL_NAME key:value key2:value2 --output json

# Function-call style (better for complex/quoted args)
mcporter call 'github.TOOL_NAME(key: "value", key2: "value2")' --output json

Always use --output json for machine-readable results.

- **`pull_request_read` method param is critical** — it's one tool with 7 methods: `get`, `get_diff`, `get_comments`, `get_reviews`, `get_status`, `list_files`, `get_review_comments`. Always specify the method. - **`get_file_contents` ref param** supports `refs/heads/BRANCH`, `refs/tags/TAG`, `refs/pull/PR/head` for reading files at any ref. Omit ref for default branch. - **`search_code` query syntax**: `content:X language:Y org:Z repo:A/B path:C filename:D extension:E`. These are GitHub qualifiers, not free text. - **Pagination**: list/search tools support `page` (1-indexed) + `perPage` (max 100). Default perPage varies by tool. - **`issue_read` also has methods**: `get`, `get_comments`, `get_sub_issues`, `get_labels`. Specify the one you need. - **Multi-file commits**: Use `push_files` with a `files` array to commit multiple files atomically — avoids multiple `create_or_update_file` calls. - **`list_pull_requests` sort options**: `created`, `updated`, `popularity`, `long-running`. The `long-running` sort is useful for finding stale PRs. - If `GITHUB_TOKEN` is not set, mcporter will fail with an auth error. Check with `echo $GITHUB_TOKEN`. - Discover all tools and parameters: `mcporter list github --all-parameters`
