- Initializes, lists, views, and archives bean workspaces
- Creates and bulk-creates beans with parent support
- Updates bean metadata and body with concurrency control
- Supports bulk updates and batch delete operations
- Queries beans with filters, sort, and GraphQL passthrough
- Marks markdown checklist tasks complete automatically
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
Beans MCPCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Run npx @selfagency/beans-mcp /path/to/workspace from the command line. Optional parameters include --workspace-root, --cli-path, --port, and --log-dir. The server exposes 13 public MCP tools for interacting with beans.
beans_init
Initialize Beans in the current workspace, equivalent to the extension init command.
beans_archive
Archive completed or scrapped beans, equivalent to the beans CLI archive command.
beans_view
Fetch full bean details by ID.
beans_create
Create a new bean.
beans_edit
Update bean metadata fields (status/type/priority/parent/blocking).
beans_reopen
Reopen a completed or scrapped bean into a non-closed status.
beans_update
Update bean metadata fields (status/type/priority/parent/blocking). Consolidated replacement for per-field update tools.
beans_delete
Delete a bean (intended for draft/scrapped beans).
beans_bulk_create
Create multiple beans in one call. Optionally assign all of them (or a subset) to a shared parent.
beans_bulk_update
Update multiple beans in one call. Optionally assign all of them (or a subset) to a shared parent.
beans_complete_tasks
Mark all markdown checklist tasks within a bean as completed.
beans_query
Unified query tool for refresh, filter, search, and sort operations.
beans_bean_file
Read, create, edit, or delete files under .beans (operation param).
beans_output
Read extension output log or show guidance (operation param).

Usage
``bash
npx @selfagency/beans-mcp /path/to/workspace
`
Versioning
@selfagency/beans-mcp has its own package versioning. Compatibility with the
Beans CLI is tracked separately.
At startup, the server compares the installed beans CLI version against the
hardcoded supported Beans version: 0.4.2. If they differ, it prints a warning
to stderr and continues startup.
Parameters
- --workspace-root or positional arg: Workspace root path
- --cli-path: Path to Beans CLI
- --port: MCP server port (default: 39173)
- --log-dir: Log directory
- -h, --help: Print usage and exit

<summary>Notes</summary>
- The beans_query tool is intentionally broad: prefer it for listing, searching, filtering or sorting beans, and for generating Copilot instructions (operation: 'llm_context').
- All file and log operations validate paths to keep them within the workspace or the VS Code log directory. The .beans/ prefix is automatically stripped from paths — you can pass either some-bean.md or .beans/some-bean.md and the result is the same.
- beans_update replaces many fine-grained update tools; callers should use it to keep the public tool surface small and predictable.
- beans_archive provides CLI parity for archiving completed/scrapped beans.
- Closing a parent bean via beans_update (status: completed or status: scrapped) cascades the same status to all descendants.
- Reopening a parent bean via beans_reopen cascades the target status to closed descendants (completed / scrapped).
- beans_bulk_create and beans_bulk_update are best-effort: they process each item sequentially and return a per-item result array with success/error entries rather than failing atomically.
- Frontmatter title: values are automatically double-quoted on write. Pass raw titles — quoting and escaping is handled for you.
- beans_bean_file supports update_frontmatter for atomic frontmatter-only writes; supported fields include pr and branch.
- Unfiltered list results are cached with a short burst TTL and a timestamp-probe refresh strategy. Mutation tools (beans_create, beans_update, beans_delete, etc.) invalidate the cache immediately.
- Version mismatches between beans-mcp and the Beans CLI are warning-only and non-blocking by design.
- When beanId is missing in tool input, validation errors include a hint: Did you mean \beanId\?.

Programmatic usage
Installation
`bash
npm install beans-mcp
`
Example
`typescript
import { createBeansMcpServer, parseCliArgs } from '@selfagency/beans-mcp';
const server = await createBeansMcpServer({
workspaceRoot: '/path/to/workspace',
cliPath: 'beans', // or path to beans CLI
});
// Connect to stdio transport or your own transport
`
API
createBeansMcpServer(opts)
Creates and initializes a Beans MCP server instance.
Options:
- workspaceRoot (string): Path to the Beans workspace
- cliPath (string, optional): Path to Beans CLI executable (default: 'beans')
- name (string, optional): Server name (default: 'beans-mcp-server')
- version (string, optional): Server version
- logDir (string, optional): Directory for server logs
- backend (BackendInterface, optional): Custom backend implementation
Returns: { server: McpServer; backend: BackendInterface }
startBeansMcpServer(argv)
CLI-compatible entrypoint for launching the server.
Utility Functions
- parseCliArgs(argv: string[]): Parse CLI arguments
- isPathWithinRoot(root: string, target: string): boolean: Check if path is contained within root
- sortBeans(beans, mode): Sort beans by specified mode
Types & Schemas
Export of GraphQL schema, Zod validation schemas, and TypeScript types for Beans records and operations.
Agent Skills (
skills-npm, skills.sh)
This package ships a built-in Agent Skill under skills/ and also publishes that skill in a format that fits the broader open skills ecosystem surfaced by skills.sh.
- Skill path in package: skills/beans-mcp/SKILL.md
- Published skill artifact: https://beans-mcp.self.agency/.well-known/agent-skills/beans-mcp/SKILL.md
- Published discovery index: https://beans-mcp.self.agency/.well-known/agent-skills/index.json
- Compatible with discovery tools that scan: node_modules/*/skills//SKILL.md
That means you can use it with npm-based workflows such as skills-npm, while also pointing ecosystem tooling at the published skill artifact and discovery index used by skills catalogs like skills.sh.
To symlink installed npm-packaged skills into your agent workspace, you can use skills-npm` in your consuming project.
