An MCP server for advanced AI workflow planning, sequential thinking, and task management
An MCP server for advanced AI workflow planning, sequential thinking, and task management. The mcp complex plans mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 6 defined tools rather than through you.
A Model Context Protocol (MCP) server designed to enhance AI workflows with advanced planning and sequential thinking capabilities. This server enables AI agents to create structured plans, manage tasks efficiently, and integrate seamlessly with development environments.
Everything the assistant can do here goes through one of these:
createPlan — Create structured plans for complex tasksupdatePlan — Modify existing plans using SEARCH/REPLACE blocksdeletePlan — Remove completed or obsolete planslistPlans — List all available plans in the current projectopenInEditor — Open files in your configured editor for reviewsequentialThinking — Dynamic problem-solving and analysis toolInstallation goes through your MCP client rather than a global install: point it at npm on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
You will need 4 environment variables: MCP_COMPLEX_PLANS_DEFAULT_EDITOR, MCP_COMPLEX_PLANS_AUTO_DELETE_PLANS, MCP_COMPLEX_PLANS_PLANS_DIR, MCP_COMPLEX_PLANS_DISABLED_TOOLS. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of planning and project tracking servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP Complex Plans's toolset — createPlan, updatePlan, deletePlan and 3 more — is a fair guide to whether it matches your workflow. It is maintained by tuchsoft; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Your workspace, on speaking terms with AI — search, read and write Notion pages and databases.
Issue tracking at the speed of conversation — Linear's official hosted server with OAuth and zero install.
Search and read your Drive — Docs, Sheets and files become context your assistant can actually use.
Your assistant inside the workspace — read channels, search history, post messages and tame the noise.
Metabase ships its own MCP endpoint — search your BI content, build and run queries, and save questions and dashboards without leaving the chat.
Stop letting your assistant hallucinate n8n node parameters — this server hands it the real schemas, templates and validation.
