Persistent sequential thinking MCP — chain-of-thought reasoning that survives sessions, resumes across agents, and saves conclusions as plan
Connect Zerodb to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Persistent sequential thinking MCP — chain-of-thought reasoning that survives sessions, resumes across agents, and saves conclusions as plan artifacts. Powered by ZeroDB. Zero-config: agents self-provision a ZeroDB account on first run, no. The zerodb mcp server is what makes that connection.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
sequential_think — Perform a sequential reasoning step. Chain multiple calls for complex, multi-step problemssequential_conclude — Finalize a reasoning chain and save the conclusion as a persistent ZeroDB plan artifact. Returns an artifact_id you can pass to sequential_resume insequential_resume — Load a prior reasoning chain from ZeroDB and continue from where it left off — in any session, on any agentInstallation goes through your MCP client rather than a global install: point it at zerodb-sequential-thinking-mcp 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.
Configuration is passed through the environment: ZERODB_CONFIG_DIR, ZERODB_API_KEY, ZERODB_PROJECT_ID, ZERODB_EMAIL, ZERODB_BASE_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Zerodb's toolset — sequential_think, sequential_conclude, sequential_resume — is a fair guide to whether it matches your workflow. It is maintained by ainative-studio; worth a glance at recent repository activity before you build anything load-bearing on it.

| Tool | What it does |
|---|---|
| sequential_think | Perform a sequential reasoning step. Chain multiple calls for complex, multi-step problems. |
| sequential_conclude | Finalize a reasoning chain and save the conclusion as a persistent ZeroDB plan artifact. Returns an artifact_id you can pass to sequential_resume in any future session or agent. |
| sequential_resume | Load a prior reasoning chain from ZeroDB and continue from where it left off — in any session, on any agent. |
