backlog-mcp
An MCP server that gives AI agents structured read/write access to a story-based project backlog. Agents can list stories, read content, update status, and append notes — all backed by plain markdown files that live inside your project repository.
How collaboration works
There is no shared server. The backlog files live in your repo under requirements/, committed and versioned alongside your code. Collaboration between agents, or between an agent and a human, works exactly the way the rest of your codebase does: through git. If two agents update different stories concurrently, git merges them. If they touch the same line, you resolve it like any other merge conflict.
The MCP server is a local process each agent runs for itself. It reads and writes files; git handles the rest.
Install
Download the latest binary for your platform from the Releases page and put it somewhere on your $PATH.
Or, if you have Go installed:
go install github.com/corbym/backlog-mcp@latest
Build from source
go mod tidy
go build -o backlog-mcp .
Setup
Initialise a requirements/ folder in your project root:
./backlog-mcp init /path/to/your/project/requirements
This creates:
requirements/
requirements-index.md # master index — source of truth for epics and story status
backlog.md # priority-ordered list of not-done stories
epic-001-example/
story-001.md # example story file
Commit the requirements/ folder to your repo. Edit the files to add your own epics and stories.
Running
./backlog-mcp
The server looks for a requirements/ directory relative to the working directory it is launched from. Claude Code sets the working directory to the project root, so no configuration is needed.
Claude Code config (.claude/settings.json in your project, or ~/.claude/settings.json globally):
{
"mcpServers": {
"backlog-mcp": {
"command": "/path/to/backlog-mcp"
}
}
}
Tools
| Tool | Description |
|---|---|
list_stories | List stories, optionally filtered by epic_id or status |

Environment variables
| Variable | Required | Default | Description |
|---|---|---|---|
BACKLOG_ROOT | no | requirements | Override the path to the requirements directory |
BACKLOG_TRANSPORT | no | stdio | Set to http for HTTP/SSE mode |
BACKLOG_HTTP_ADDR | no | 0.0.0.0:8080 | Listen address for HTTP mode |
File format
requirements-index.md — one epic section per heading, one story per table row:
## EPIC-001: Combat System — `draft`
| Story | Title | Status |
|-------|-------|--------|
| [STORY-001](./epic-001-combat-system/story-001.md) | Basic combat | draft |
backlog.md — priority-ordered numbered list:
1. **STORY-001** — Basic combat
2. **STORY-002** — Enemy AI *(in-progress)*
Story files live at epic-NNN-slug/story-NNN.md under BACKLOG_ROOT.
Status values: draft, in-progress, done, blocked
Notes
- File writes are atomic (temp file + rename) — a crash mid-write cannot corrupt your files.
- The filesystem is the source of truth. The MCP server never owns the data.
