MCP SERVERManage Git Mob from the agent — add team members once, set who is pairing right now, and get the Co-authored-by trailers for the current session.
LABSCO SUMMARY
The session is configuration; the trailers are the thing that has to end up in the commit message. An agent composing a commit needs the literal Co-authored-by lines, and having them as their own call means it does not have to reconstruct them from names and emails and get the format subtly wrong. Setting a session by short keys rather than full identities is the other ergonomic decision that matters in practice — pairing changes daily and typing two email addresses each morning is why people stop bothering.
A client for the Git Mob CLI, which attaches Co-authored-by trailers to commits during pairing and mob sessions: team member management, session control, and trailer retrieval.
The Git Mob CLI, which the setup tools configure either globally or per repository.
One command — npx -y git-mob-mcp-server
USE CASES
Configure Git Mob globally or install the local hook for this repository, then check the CLI's own usage if something is unclear.
Set the session from the team member keys, and clear it when the session ends.
Pull the literal Co-authored-by trailers for the active session rather than reconstructing them from names and emails.
Add a member by key, name and email once, and remove the ones who have moved on.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
add_team_memberAdds a new team member using their key, name, and email. This member can then be used in a pairing or mobbing sessions as a cauthor. The first name is a good choice for the key.Ask the user if they want mob or pair with this team member.
clear_mob_sessionClears the active mob or pairing session.
delete_team_memberDeletes a team member by their key. User can only delete a team member they have added previously. If user did not specify a key, show them list of existing team members and ask them to select one.
get_git_mob_cli_helpDisplays general help and usage information for the Git Mob CLI. You can optionally provide a command ('setup', 'coauthor', or 'help') to get detailed help for that specific command.
list_mob_session_coauthor_trailersLists the git Co-authored-by trailers for the coauthors currently included in the active mob or pairing session. If Git Mob is setup, these Co-authored-by trailers will be automatically added to the commit's message when making commits during the session.
list_mob_session_coauthorsLists all coauthors currently included in the active mob or pairing session. If Git Mob is setup, these coauthors will be automatically added as Co-authored-by trailers to the commit's message when making commits during the session.
list_team_membersLists all team members that have been added to Git Mob. The team members can then be used in pairing / mobbing sessions as coauthors.Each entry is formatted as: <key> <name> <email>.Ask the user which team member(s) they want to pair or mob with.
set_mob_session_coauthorsSets the active pairing or mob session by specifying the keys of the team members to include as coauthors. If Git Mob is setup, these coauthors will be automatically added as Co-authored-by trailers to the commit's message when making commits during the session.
setup_git_mobConfigures the Git Mob CLI globally for all repositories on your system. This one-time setup installs a global prepare-commit-msg git hook, which automatically appends Co-authored-by trailers to commit messages during mob or pairing sessions. If a repository overrides the core.hooksPath git configuration (e.g., when using Husky), the setupGitMobLocally tool needs to be invoked in addition to this. If Git Mob isn't working as expected, ask the user if they have completed this initial setup.
setup_git_mob_locallySets up the Git Mob CLI for the current repository by installing a local prepare-commit-msg git hook. This hook delegates to the global prepare-commit-msg hook configured by setupGitMob tool. Use this tool only if your repository overrides the core.hooksPath git configuration (e.g., when using Husky). Note: You must run setupGitMob tool at least once before using this tool.
