Latitude — Plugins & Extensions

Marketplace plugins / extensions for the Latitude MCP server across the major coding agents and IDEs.

Each plugin is a one-click installer for the Latitude MCP server — a remote, OAuth-authenticated, streamable HTTP Model Context Protocol server living at https://api.latitude.so/v1/mcp. Once installed and authorized, the host agent can read and manage your Latitude workspace (projects, members, keys, traces, annotations, scores, searches, issues, datasets, and more).

About Latitude: open-source AI agent monitoring platform. Full observability into what's failing in production. Discover underlying issues, get alerts when something breaks, and verify your fix worked.

Each <platform>/ subfolder is a self-contained, publishable repository for its target marketplace. The plan is to publish each platform as its own public repo (e.g. latitude-cursor, latitude-claude, …) and link them back into this monorepo via git submodules, so all five plugins can be edited from one working copy.

Each <platform>/ ships its own LICENSE, .gitignore, README.md, and assets/ — once detached, the folder needs zero changes to be a working repo for marketplace submission.

Icons are duplicated into each plugin's assets/ because marketplaces clone/zip plugins individually and assets need to be resolvable inside each plugin's tree.

Working with submodules

After each platform repo is created and added back as a submodule, the typical loop is:

# Initial clone
git clone --recurse-submodules <this-repo>
# Or, if already cloned without submodules:
git submodule update --init --recursive

# Pull latest for all platforms
git submodule update --remote --merge

# When making changes in <platform>/, push the submodule first,
# then commit the new SHA in the monorepo:
cd cursor && git add . && git commit -m "..." && git push && cd ..
git add cursor && git commit -m "bump cursor submodule" && git push

If submodule UX becomes a friction point, an alternative is keeping this as a regular monorepo and using a GitHub Action like s0/git-publish-subdir-action to mirror each <platform>/ to its own public repo on push.

What gets shipped

Every plugin ships only the Latitude MCP server registration. No skills, rules, agents, commands, hooks, or other components. The goal is a friction-free one-click install of the MCP server.

After install, the user is taken through the host's standard MCP authorization flow (OAuth) and chooses the Latitude organization the agent should access.

Per-platform quick reference

Platform	Manifest	MCP config	Submission
Cursor	cursor/.cursor-plugin/plugin.json	cursor/mcp.json	https://cursor.com/marketplace/publish
Claude Code	claude/.claude-plugin/plugin.json	claude/.mcp.json	https://claude.ai/settings/plugins/submit
Codex	codex/.codex-plugin/plugin.json	codex/.mcp.json	Self-serve publishing coming soon
Zed	zed/extension.toml + Rust crate	context_server_command in src/lib.rs	PR to zed-industries/extensions
Antigravity	antigravity/plugin.json	antigravity/mcp_config.json	Manual install (no public submission flow yet)

Validating

A single command validates all five plugins:

./scripts/validate-all.sh

Under the hood it runs claude plugin validate, Codex's validate_plugin.py, cargo build for the Zed extension, and a cursor-agent --plugin-dir smoke-load for Cursor. See AGENTS.md for the per-platform details.
