Saga

IdeaCred

A Jira-like project tracker MCP server for AI agents. SQLite-backed, per-project scoped, with full hierarchy and activity logging — so LLMs never lose track.

No more scattered markdown files. saga-mcp gives your AI assistant a structured database to track projects, epics, tasks, subtasks, notes, and decisions across sessions.

Features

• Full hierarchy: Projects > Epics > Tasks > Subtasks
• Task dependencies: Express sequencing with auto-block/unblock when deps are met
• Comments: Threaded discussions on tasks — leave breadcrumbs across sessions
• Templates: Reusable task sets with {variable} substitution
• Dashboard: One tool call gives full overview with natural language summary
• SQLite: Self-contained .tracker.db file per project — zero setup, no external database
• Activity log: Every mutation is automatically tracked with old/new values
• Notes system: Decisions, context, meeting notes, blockers — all searchable
• Batch operations: Create multiple subtasks or update multiple tasks in one call
• 31 focused tools: With MCP safety annotations on every tool
• Import/export: Full project backup and migration as JSON (with dependencies and comments)
• Source references: Link tasks to specific code locations
• Auto time tracking: Hours computed automatically from activity log
• Cross-platform: Works on macOS, Windows, and Linux

Quick Start

With Claude Code

Add to your project's .mcp.json:

{
  "mcpServers": {
    "saga": {
      "command": "npx",
      "args": ["-y", "saga-mcp"],
      "env": {
        "DB_PATH": "/absolute/path/to/your/project/.tracker.db"
      }
    }
  }
}

With Claude Desktop

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "saga": {
      "command": "npx",
      "args": ["-y", "saga-mcp"],
      "env": {
        "DB_PATH": "/absolute/path/to/your/project/.tracker.db"
      }
    }
  }
}

Manual install

npm install -g saga-mcp
DB_PATH=./my-project/.tracker.db saga-mcp

Configuration

saga-mcp requires a single environment variable:

Variable	Required	Description
DB_PATH	Yes	Absolute path to the .tracker.db SQLite file. The file and schema are auto-created on first use.

No API keys, no accounts, no external services. Everything is stored locally in the SQLite file you specify.

Usage Examples

Example 1: Starting a project with dependencies

User prompt: "Set up tracking for my new e-commerce API project"

Tool calls:

tracker_init({ project_name: "E-Commerce API", project_description: "REST API for online store" })
epic_create({ project_id: 1, name: "Authentication", priority: "high" })
task_create({ epic_id: 1, title: "Design auth schema", priority: "critical" })
task_create({ epic_id: 1, title: "Implement JWT auth", priority: "high", depends_on: [1] })
task_create({ epic_id: 1, title: "Add OAuth2 Google login", priority: "medium", depends_on: [2] })

Result: Task 2 and 3 are auto-blocked because their dependencies aren't done yet. When task 1 is marked done, task 2 auto-unblocks.

Example 2: Resuming work with dashboard summary

Tool calls:

tracker_dashboard({})

Response includes a natural language summary:

"E-Commerce API: 5 tasks across 2 epics. 40% complete. Active: Authentication (2/3 done). Next up: Product Catalog (2 tasks). 1 blocked task(s)."

Plus the full structured data (stats, epics, blocked tasks, overdue tasks, activity, notes).

Example 3: Using templates for repeated workflows

Create a template:

template_create({
  name: "feature_workflow",
  description: "Standard feature implementation",
  tasks: [
    { "title": "Design {feature} API", "priority": "critical", "estimated_hours": 2 },
    { "title": "Implement {feature}", "priority": "high", "estimated_hours": 8 },
    { "title": "Write tests for {feature}", "priority": "high", "estimated_hours": 4 },
    { "title": "Document {feature}", "priority": "medium", "estimated_hours": 1 }
  ]
})

Apply it:

template_apply({ template_id: 1, epic_id: 2, variables: { "feature": "user auth" } })

Creates 4 tasks: "Design user auth API", "Implement user auth", "Write tests for user auth", "Document user auth".

Example 4: Task comments as decision trail

comment_add({ task_id: 5, content: "Investigated root cause: CORS headers missing on preflight" })
comment_add({ task_id: 5, content: "Fixed by adding OPTIONS handler. Tested with curl." })
task_update({ id: 5, status: "done" })

Comments persist across sessions — next time an agent calls task_get(5), it sees the full discussion thread.

How It Works

saga-mcp stores everything in a single SQLite file (.tracker.db) per project. The database is auto-created on first use with all tables and indexes — no migration step needed.

Hierarchy

Project
  └── Epic (feature/workstream)
        └── Task (unit of work)
              ├── Subtask (checklist item)
              ├── Comment (discussion thread)
              └── Dependencies (blocked by other tasks)

Task Dependencies

Tasks can depend on other tasks. When you set depends_on: [2, 3] on a task:

• The task is auto-blocked if any dependency isn't done
• When a dependency is marked done, downstream tasks are re-evaluated
• If all dependencies are met, the blocked task auto-unblocks to todo

Note Types

Notes replace scattered markdown files. Each note has a type:

Type	Use case
general	Free-form notes
decision	Architecture/design decisions
context	Conversation context for future sessions
meeting	Meeting notes
technical	Technical details, specs
blocker	Blockers and issues
progress	Progress updates
release	Release notes

Activity Log

Every create, update, and delete is automatically recorded:

{
  "summary": "Task 'Fix CORS issue' status: blocked -> done",
  "action": "status_changed",
  "entity_type": "task",
  "entity_id": 15,
  "field_name": "status",
  "old_value": "blocked",
  "new_value": "done",
  "created_at": "2026-02-21T18:30:00"
}

Privacy Policy

saga-mcp is a fully local, offline tool. It does not:

• Collect any user data
• Send any data to external servers
• Require internet access after installation
• Use analytics, telemetry, or tracking of any kind

All data is stored exclusively in the local SQLite file specified by DB_PATH. You own your data completely. Uninstalling saga-mcp and deleting the .tracker.db file removes all traces.
