🚧 Work in Progress: This project is under active development.

A Model Context Protocol (MCP) server for org-mode knowledge management. Provides search, content access, and note linking capabilities for your org-mode files through the MCP protocol.

Features

MCP Resources

org:// — List all org-mode files in configured directories
org://{file} — Access raw content of {file}
org-outline://{file} — Get hierarchical structure of {file} as JSON
org-heading://{file}#{heading} — Access specific headings by path
org-id://{id} — Find content by org-mode ID properties
org-agenda:// — List all agenda items and tasks
org-agenda://today — Today's scheduled agenda items
org-agenda://week — This week's scheduled agenda items

MCP Tools

org-file-list — List all org files in configured directories
org-search — Search for text content across all org files using fuzzy matching
org-agenda — Query agenda items with filtering by dates, states, tags, and priorities

CLI Tool

org-cli config init — Create default configuration file
org-cli config show — Display current configuration
org-cli config path — Show configuration file location
org-cli list — List all .org files in configured directory
org-cli init — Initialize or validate an org directory
org-cli read — Read the contents of an org file
org-cli outline — Get the outline (headings) of an org file
org-cli heading — Extract content from a specific heading in an org file
org-cli element-by-id — Extract content from an element by ID across all org files
org-cli search — Search for text content across all org files using fuzzy matching
org-cli agenda list — List all tasks (TODO/DONE items)
org-cli agenda today — Show today's scheduled tasks
org-cli agenda week — Show this week's scheduled tasks
org-cli agenda range — Show tasks in custom date range

Configuration

The project uses a TOML configuration file located at ~/.config/org-mcp/config.toml (or $XDG_CONFIG_HOME/org-mcp/config.toml).

Configuration Hierarchy

Configuration is resolved in the following order (highest priority first):

CLI flags — Command-line arguments override everything
Environment variables — ORG_* prefixed variables
Configuration file — TOML file in config directory
Default values — Built-in fallbacks

Configuration File Format

[org]
# Root directory containing org-mode files
org_directory = "~/org/"
# Default notes file for new notes
org_default_notes_file = "notes.org"
# Agenda files to include
org_agenda_files = ["agenda.org", "projects.org"]
# Extra files for text search beyond regular org files
org_agenda_text_search_extra_files = ["archive.org"]
org_todo_keywords = [
    "TODO",
    "|",
    "DONE",
]

[logging]
# Log level: trace, debug, info, warn, error
level = "info"
# Log file location (MCP server only, CLI logs to stderr)
file = "~/.local/share/org-mcp-server/logs/server.log"

[cli]
# Default output format for CLI commands
default_format = "plain"  # plain | json

Environment Variables

Org-mode Configuration

ORG_ORG__ORG_DIRECTORY — Root directory for org files
ORG_ORG__ORG_DEFAULT_NOTES_FILE — Default notes file name
ORG_ORG__ORG_AGENDA_FILES — Comma-separated list of agenda files
ORG_ORG__ORG_AGENDA_TEXT_SEARCH_EXTRA_FILES — Comma-separated extra search files

Logging Configuration

ORG_LOGGING__LEVEL — Log level (debug, info, warn, error, trace)
ORG_LOGGING__FILE — Log file location

Server Configuration

ORG_SERVER__MAX_CONNECTIONS — Maximum number of concurrent connections (default: 10)

CLI Configuration

ORG_CLI__DEFAULT_FORMAT — Default output format for CLI commands (plain, json)

Configuration Commands

# Create default configuration file
org config init

# Show current resolved configuration
org config show

# Show configuration file path
org config path

Usage Examples

Basic Commands

# List all org files using configuration
org list

# List with JSON output
org list --format json

# Search across all configured org files
org search "project planning"

# Search with custom parameters
org search "TODO" --limit 5 --format json --snippet-size 75

# Override root directory for a single command
org --root-directory ~/documents/org search "meeting notes"

Agenda Commands

# List all tasks (TODO/DONE items)
org agenda list

# List tasks with specific TODO states
org agenda list --states TODO,IN_PROGRESS

# Filter tasks by priority
org agenda list --priority A

# Filter by tags
org agenda list --tags work,urgent

# Show today's scheduled tasks
org agenda today

# Show this week's tasks
org agenda week

# Show tasks in custom date range
org agenda range --start 2025-10-20 --end 2025-10-27

# JSON output for agenda
org agenda list --format json --limit 10

Architecture

Multi-crate Rust workspace:

org-core — Business logic and org-mode parsing
org-mcp-server — MCP protocol implementation
org-cli — CLI interface for testing and direct usage

Built with:

orgize for org-mode parsing
rmcp for MCP protocol
tokio for async runtime
nucleo-matcher for fuzzy text search

MCP Server Integration

AI Agent Configuration

Add the following to your agent configuration (e.g., ~/.config/opencode/opencode.json, ~/.claude.json, etc.):

{
  "mcpServers": {
    "org-mode": {
      "command": "/path/to/org-mcp-server",
      "args": [],
      "env": {}
    }
  }
}

Or if installed via Nix:

{
  "mcpServers": {
    "org-mode": {
      "command": "nix",
      "args": ["run", "github:szaffarano/org-mcp-server"],
      "env": {}
    }
  }
}

Environment Variable Configuration

You can configure the MCP server through environment variables in your agent configuration:

{
  "mcpServers": {
    "org-mode": {
      "command": "/path/to/org-mcp-server",
      "args": [],
      "env": {
        "ORG_ORG__ORG_DIRECTORY": "/path/to/your/org/files",
        "ORG_LOGGING__LEVEL": "info",
        "ORG_SERVER__MAX_CONNECTIONS": "20"
      }
    }
  }
}

Development

# Run all tests
cargo test

# Run specific crate tests
cargo test -p org-core

# Format and lint
cargo fmt
cargo clippy

# Run examples
cargo run --example <name>
