View on GitHub ↗explorer-mcp is a lightweight, read-only MCP server that gives AI quick access to Git repos, folder structures, and context. It cuts time and token usage by handling exploration internally and feeding results to AI agents.
Why should an AI agent collect context piece by piece when an MCP can collect more information faster and present it in a simple, self-explanatory, compact format?
Table of Contents - Explore resources - Enabled by default - Opt-in - Response design - Requirements - Getting Started - Install via go - Install via wget - Build requirements - Build - Install go
explorer-mcp collects diffrent resources and provides them to the requesting AI Agent.
Resources can be enabled or disabled via CLI flags and environment variables. See explorer-mcp -h or explorer-mcp print -h. Some resources are omitted at runtime when prerequisites are missing (no git repo, no container CLI, no opencode binary, etc.).
- structure: File tree under projectRootPath up to scan depth; relative paths, / for truncated dirs - git: Branch or detached head, dirty files, recent commits, diffstat - workspace: Parent and sibling projects around projectRootPath - dependencies: Dependencies from manifests (go.mod, package.json, requirements.txt, …) - container: Container CLIs in PATH and running containers linked to the project - tools: Makefile targets, package.json scripts, root shell scripts
- cli: Common CLI tools available in PATH. This could mislead an AI agent and cause complications. - opencode: Effective OpenCode permission rules and MCP server names via opencode debug agent build -

Git-native persistent memory for AI coding agents. Implements Google OKF v0.2 with sub-300µs in-memory BM25 search, embedded MCP server, and progressive disclosure. Slashes token bloat by 80% with zer
vshulcz/deja-vuYour agents already solved this. deja finds it — retroactive search and MCP recall over the session logs your coding agents already wrote. Cross-agent, SSH-portable, one zero-dep binary, fully local.
olucurious/watchtowerSelf-hosted error tracking. A drop-in for Sentry and AppSignal SDKs: one Go binary and Postgres, with Slack, Linear, email and an MCP server for coding agents.
KnifeLemon/DroidlineAndroid automation from code. Test your apps on real phones, script the tasks you repeat, run a shelf of phones, or let an AI agent use one, from Python, Node.js, the CLI, HTTP or Appium clients. No A
enowdev/succubusCross-agent coordination for AI coding agents. One daemon, one database — so multiple agents in one repo can see each other's plan, tasks, and file claims.
