devflow MCPサーバー

---

Overview

The most complete MCP server for developer workflow automation. 32 tools that connect Jira (Cloud + Server) with GitHub/GitLab (cloud + self-hosted) — so your AI assistant can manage issues, branches, PRs, and deployments without you ever opening a browser tab.

It auto-detects your Jira version and git provider, enforces configurable safety rules, and lets you define custom YAML flow playbooks for repeatable workflows. Projects are configured once and remembered — each with its own Jira instance, git provider, branch conventions, credentials, and directory scopes. The project that matches your current directory activates automatically (default), or you can switch to another for the session (active). All credentials stay local in ~/.devflow-mcp/ — nothing is synced, nothing is tracked, nothing leaves your machine.

Just Talk to It

You don't memorize tool names. You talk naturally and the assistant picks the right tools.

Project Scopes

Each project has paths (scopes) — the directories that belong to it. A directory can only be the scope of one project.

This gives you two concepts:

• Default project: The project whose scope matches your current working directory. This is automatic and persistent — if you are inside C:/repos/my-backend and that directory is a scope of my-backend, then my-backend is the default. No action needed.

• Active project: The project you are currently working with. By default it equals the default project, but you can switch it manually with df_project_switch for the current session. This resets to the default when you restart.

df_project_list shows both the default and active indicators so you always know where you stand.

Practical example

"Set up a project called my-backend"
  → CWD (C:/repos/my-backend) is auto-added as scope

"Set up another called my-frontend"
  → Run from C:/repos/my-frontend, that directory becomes its scope

"List projects"
  → my-backend   [default] [active]    scopes: C:/repos/my-backend
     my-frontend                        scopes: C:/repos/my-frontend

"Switch to my-frontend"
  → Session switches. Now my-frontend is active for checking issues, etc.

"List projects"
  → my-backend   [default]             scopes: C:/repos/my-backend
     my-frontend  [active]              scopes: C:/repos/my-frontend

Close and reopen → my-backend is active again (matches CWD = default)

This means you can work across multiple projects with different Jira instances and git providers — the right credentials are always selected based on where you are, and you can always override for the session when needed.

Tools

32 tools organized in 5 categories.

Projects (5)

Tool	Description
df_project_setup	Configure a new project (Jira + Git, auto-detects everything)
df_project_update	Modify project configuration
df_project_list	List all configured projects (shows default + active)
df_project_switch	Switch the active project for the current session
df_project_delete	Delete a project

df_project_setup with:
  name: "my-project"
  jiraUrl: "https://myteam.atlassian.net"
  jiraEmail: "dev@myteam.com"
  jiraToken: "ATATT3x..."
  jiraProjectKey: "PROJ"
  gitToken: "ghp_..."

Auto-detects:
  - Jira Cloud (API v3)
  - GitHub (org/my-project)
  - Base branch: main
  - Scope: your CWD (auto-added)

Jira (6)

Tool	Description	Confirmation
df_issues	List my assigned issues (filters by project)	--
df_issue	Full issue detail	--
df_statuses	Available transitions for an issue	--
df_transition	Move issue to another status	Yes
df_assign	Assign issue to current user	--
df_comment	Comment on an issue	Yes

Git (7)

Tool	Description	Confirmation
df_branch	Create branch (feat/ or fix/) from base	Yes
df_find_branch	Search branch by issue key	--
df_checkout	Switch branch (with safety guard)	--
df_pull	Pull current branch from remote	--
df_push	Push current branch to remote	Yes
df_merge	Merge a branch into the current one	Yes
df_pr	Create PR (GitHub) or MR (GitLab)	--

Important: df_branch, df_checkout, and df_push verify the working directory before executing. They block if there are uncommitted files or unpushed commits, listing exactly what needs attention. This prevents accidental work loss.

Flows (5)

Tool	Description
df_flow_create	Create a custom flow
df_flow_list	List all flows
df_flow_get	View flow details
df_flow_update	Modify an existing flow
df_flow_delete	Delete a flow (protects start-task)

df_rule_create	Create a global rule	Global
df_rule_list	List all rules	Global
df_rule_get	View rule details	Global
df_rule_update	Modify a rule	Global

df_rule_project_remove	Remove a project rule or override	Project

Flows

Flows are YAML playbooks that define step sequences. They don't run automatically -- you tell the assistant when to use them.

Default: start-task

Triggered when you say something like "let's work on PROJ-123":

name: start-task
trigger: "when the user says 'let's work on', 'start task', 'new task' + issue ID"
steps:
  - tool: df_issue
    note: "Read issue detail and summarize the task"
  - tool: df_find_branch
    note: "Check if a branch already exists for this issue"
  - tool: df_branch
    confirm: true
    note: "Only if no existing branch was found"
  - tool: df_statuses
    note: "Get transitions to find the 'In Progress' transition ID"
  - tool: df_transition
    target: "In Progress"
    confirm: true
  - tool: df_assign
    note: "Assign the issue if it has no assignee"

Custom flows

Create your own by asking naturally:

"Create a flow called 'finish-task' that pushes, creates a PR, and comments on Jira"

name: finish-task
trigger: "when the user says 'finish task', 'wrap up' + issue ID"
steps:
  - tool: df_push
    confirm: true
    note: "Push pending commits"
  - tool: df_pr
    note: "Create PR/MR to base branch"
  - tool: df_comment
    confirm: true
    note: "Comment on the issue with the PR link"

The start-task flow can be modified but not deleted. Use df_flow_update to change any flow's steps, trigger, or name.

---

Rules

Rules are configurable guards that block or warn about actions. Two levels: global and per-project.

Default rules

Rule	Scope	Action	What it does
no-merge-to-base	git	block	Prevent direct push/merge to main/master
no-merge-from-dev	git	block	Prevent merging dev/develop/int branches out
no-close-issues	jira	block	Prevent closing issues (Done, Closed, Resolved...)
only-own-issues	jira	block	Prevent modifying issues assigned to others

Project overrides

Each project can override global rules or define its own:

# Disable a global rule for one project
df_rule_project_override: name="no-close-issues", enabled=false

# Add a project-only rule
df_rule_project_add: name="no-push-friday", scope="git", action="warn"

# Remove an override or project rule
df_rule_project_remove: name="no-close-issues"

Custom rules

df_rule_create:
  name: "no-push-friday"
  description: "Warn when pushing on Fridays"
  scope: "git"       # git | jira | all
  action: "warn"     # block | warn

Note: Rule resolution order: Global rules load first, then project overrides are applied (project wins), then project-specific rules are added. Rules are filtered by scope and enabled state before evaluation.

---

Storage

Everything lives in ~/.devflow-mcp/ — your home directory, never inside any git repository. Jira tokens, GitHub PATs, GitLab tokens — all stored locally with 600 permissions (owner-only read/write). Nothing gets committed, nothing gets pushed, nothing leaves your machine.

~/.devflow-mcp/
├── projects/              # Project configs (.json) — credentials included
│   ├── my-project.json    # Jira URL, token, GitHub PAT, branch rules, scopes
│   └── other-project.json
├── flows/                 # Flow definitions (.yaml)
│   └── start-task.yaml
├── rules/                 # Global rules (.json)
│   ├── no-merge-to-base.json
│   ├── no-merge-from-dev.json
│   ├── no-close-issues.json
│   └── only-own-issues.json
├── active-project         # Current active project (plain text)
└── config.json            # Server configuration

Project resolution works automatically: devflow-mcp matches your current working directory against each project's paths (scopes). The matching project becomes the default. You can override it for the session with df_project_switch, which sets the active project. On restart, the active project resets to whatever the default is for your CWD. If no match is found and no active project is set, it prompts you to configure with df_project_setup.
