When running as an MCP server, subprocesses must not inherit stdin because
MCP uses stdin for JSON-RPC protocol communication. Inherited stdin causes
subprocesses to block indefinitely waiting for input or steal bytes from
the MCP protocol stream.
Added stdin=subprocess.DEVNULL (or asyncio.subprocess.DEVNULL for async)
to all subprocess calls:
- server.py: _resolve_workspace_root() git subprocess
- tools.py: _resolve_workspace_root() git subprocess
- bd_client.py: _run_command(), _check_version(), add_dependency(),
quickstart(), and init() async subprocess calls

Add BEADS_DIR as a replacement for BEADS_DB to point to the .beads
directory instead of the database file directly.
Rationale:
- With --no-db mode, there's no .db file to point to
- The .beads directory is the logical unit (contains config.yaml, db
files, jsonl files)
- More intuitive: point to the beads directory not the database file
Implementation:
- Add BEADS_DIR environment variable support to FindDatabasePath()
- Priority order: BEADS_DIR > BEADS_DB > auto-discovery
- Maintain backward compatibility with BEADS_DB (now deprecated)
- Update --no-db mode to respect BEADS_DIR
- Update MCP integration (config.py, bd_client.py)
- Update documentation to show BEADS_DIR as preferred method
Testing:
- Backward compatibility: BEADS_DB still works
- BEADS_DIR works with regular database mode
- BEADS_DIR works with --no-db mode
- Priority: BEADS_DIR takes precedence over BEADS_DB
Follow-up issues for refactoring:
- bd-efe8: Refactor path canonicalization into helper function
- bd-c362: Extract database search logic into helper function

The --db flag was removed in bd v0.20.1 in favor of automatic database
discovery via cwd. The MCP server now relies on passing the workspace
directory via cwd parameter instead of the --db flag.
This fixes compatibility with bd v0.20.1+.
Fixes#114 and #122 by adding --description/-d flag to bd update CLI
and description parameter to MCP update_issue tool.
Changes:
- CLI: Added --description flag to updateCmd
- RPC: Added Description field to UpdateArgs
- Daemon: Updated updatesFromArgs to handle description
- MCP: Added description to update_issue, UpdateIssueParams, and clients
- Storage: description already supported in allowedUpdateFields
Tested in both daemon and direct modes.
- Update bd update to use --acceptance instead of --acceptance-criteria
- Update MCP client to use --acceptance flag
- Simplify SKILL.md documentation now that both commands use same flag

Implements bd-121: Global daemon with system-wide socket
Changes:
- Add --global flag to daemon command
- Use ~/.beads/bd.sock when --global is set
- Skip git repo validation for global daemon
- Update daemon discovery to check ~/.beads/ as fallback
- Both Go CLI and Python MCP client check global socket
- Update all tests to pass global parameter
Benefits:
- Single daemon serves all repos on system
- No per-repo daemon management needed
- Better resource usage for users with many repos
- Automatic fallback when local daemon not running
Usage:
bd daemon --global # Start global daemon
bd daemon --status --global # Check global status
bd daemon --stop --global # Stop global daemon

This PR fixes three bugs that prevented the MCP plugin from working:
1. **Fixed parameter name mismatch in tools.py**
- Changed `workspace_root=workspace_root` to `working_dir=workspace_root`
- The `create_bd_client()` function expects `working_dir` parameter,
but tools.py was passing `workspace_root`
- This caused "got an unexpected keyword argument 'workspace_root'" error
2. **Added version check guard for daemon client**
- Added `hasattr(_client, '_check_version')` check before calling
- BdDaemonClient doesn't have `_check_version()` method, only BdCliClient does
- This caused "'BdDaemonClient' object has no attribute '_check_version'" error
3. **Implemented proper daemon socket detection for fallback**
- Added synchronous socket file existence check before creating daemon client
- Walks up directory tree looking for `.beads/bd.sock` file
- Only creates daemon client if socket exists, otherwise falls back to CLI
- Previously, daemon client was created but failed on first method call
- This enables the documented "prefer_daemon with automatic CLI fallback" behavior
**Testing:**
- Verified MCP tools work correctly with single-repo setup
- Confirmed automatic fallback to CLI when daemon isn't running
- Tested on macOS with bd v0.9.9
**Related Issues:**
- Addresses symptoms similar to #65 (Windows BEADS_WORKING_DIR issue)
- Added per-request storage routing in daemon server
- Server now supports Cwd field in requests for database discovery
- Tree-walking to find .beads/*.db from any working directory
- Storage caching for performance across requests
- Created Python daemon client (bd_daemon_client.py)
- RPC over Unix socket communication
- Implements full BdClientBase interface
- Auto-discovery of daemon socket from working directory
- Refactored bd_client.py with abstract interface
- BdClientBase abstract class for common interface
- BdCliClient for CLI-based operations (renamed from BdClient)
- create_bd_client() factory with daemon/CLI fallback
- Backwards-compatible BdClient alias
Next: Update MCP server to use daemon client when available
- Remove ~/.beads/default.db fallback from FindDatabasePath()
- Update daemon to error if no database found instead of falling back
- Update main.go to require explicit database initialization
- Add help/version/quickstart to commands that don't need database
- Add MCP client debug logging for database routing

Implements the `bd` reopen command across the entire MCP stack, enabling
agents to reopen closed issues with optional reason tracking for audit
trails. This addresses the need to handle regressions and incorrectly
closed issues without manual `bd` CLI intervention.
The reopen command is more explicit than `bd update --status open` and
emits a dedicated Reopened event in the audit log, making it easier to
track why issues were reopened during analysis.
Changes:
- `models.py`: Add ReopenIssueParams with issue_ids list and optional reason
- `bd_client.py`: Implement reopen() method with JSON response parsing
- `tools.py`: Add beads_reopen_issue() wrapper with Annotated types for MCP
- `server.py`: Register 'reopen' MCP tool with description and parameters
Testing (10 new):
- `test_bd_client.py`: 4 unit tests (mocked subprocess)
- `test_bd_client_integration.py`: 3 integration tests (real `bd` CLI)
- `test_mcp_server_integration.py`: 3 MCP integration tests (FastMCP Client)
- `test_tools.py`: 3 tools wrapper tests (mocked BdClient)
Also updated `README.md`.
1. Fix `test_default_beads_path_auto_detection`
- Changed beads_path to use `Field(default_factory=_default_beads_path)` so the default is evaluated at instance
creation time, not class definition time
- Updated test to mock both `shutil.which` and `os.access`
2. Fix `test_init_creates_beads_directory`
- Fixed test to pass `working_dir=temp_dir` to `BdClient` instead of using `os.chdir()`
- The `_get_working_dir()` method checks `PWD` env var first, which isn't updated by `os.chdir()`
3. Fix minor linting errors reported by `ruff` tool
4. Update `beads` version to `0.9.6` in `uv.lock` file
MCP Server test coverage is now excellent, at 92% overall maintaining our high-standards of production level quality.

The MCP server was running bd commands from the plugin installation directory,
causing the database to be created in the wrong place.
Added BEADS_WORKING_DIR config option and modified BdClient to use working
directory for subprocess calls. Falls back to PWD environment variable.
This ensures bd commands run from the user's actual project directory.

The MCP server was running all bd commands in its own installation directory
(~/.claude/plugins/marketplaces/beads-marketplace/integrations/beads-mcp/)
instead of the user's project directory. This caused databases to be created
in the wrong location.
For example, when working in ~/ai/flutter/wyvern and running `bd init --prefix wy-`,
the database was created at:
~/.claude/plugins/marketplaces/beads-marketplace/integrations/beads-mcp/.beads/wy-.db
Instead of the expected location:
~/ai/flutter/wyvern/.beads/wy-.db
Solution:
- Add `cwd=os.getcwd()` to all asyncio.create_subprocess_exec() calls
- This makes bd commands execute in the current working directory from PWD env var
- Claude Code updates PWD for the MCP server process environment
Impact:
- bd init now creates .beads/ in the correct project directory
- All bd commands (create, list, update, etc.) operate on the correct database
- Multi-project workflows work correctly without manual DB path configuration
Test results: 90/91 tests passing (1 unrelated path assertion failure)
Critical bug: MCP init tool reported success but didn't create .beads
directory. It was using --db flag which tells bd to use an existing
database elsewhere instead of creating a new one.
Root cause:
- bd_client.init() was calling _global_flags() which adds --db flag
- bd init --db <path> uses existing db instead of creating new one
- Result: init appeared to succeed but created nothing
Fix:
- Remove _global_flags() from init command
- Only pass --actor flag (safe for init)
- Do NOT pass --db flag to init (defeats the purpose)
- Add explicit comment explaining why
Testing:
- Added test_init_creates_beads_directory() integration test
- Verifies .beads directory is created in current working directory
- Verifies database file has correct prefix
- All 91 tests pass
This was causing silent failures where agents thought they initialized
bd but the .beads directory was never created.

Fixes Claude Code marketplace plugin installation failure (bd-183).
Problem: The plugin.json manifest included an engines field (borrowed from npm)
to specify minimum bd CLI version requirements. However, Claude Code's plugin
manifest schema doesn't recognize this field, causing validation errors when
installing via /plugin marketplace add.
Solution:
1. Remove the engines field from plugin.json
2. Add runtime version checking in the MCP server startup
3. Update documentation to reflect automatic version checking
Changes:
- .claude-plugin/plugin.json: Remove unsupported engines field
- integrations/beads-mcp/src/beads_mcp/bd_client.py:
- Add BdVersionError exception class
- Add _check_version() method to validate bd CLI >= 0.9.0
- Use bd version command (not bd --version)
- integrations/beads-mcp/src/beads_mcp/tools.py:
- Make _get_client() async to support version checking
- Update all tool functions to await _get_client()
- Add version check on first MCP server use
- .claude-plugin/commands/bd-version.md: Update to mention automatic checking
- PLUGIN.md: Document automatic version validation at startup
Benefits:
- Plugin installs successfully via Claude Code marketplace
- Clear error messages if bd CLI version is too old
- Version check happens once per MCP server lifetime (not per command)
- Users get actionable update instructions in error messages
Closes bd-183
