How does the server protect my private key?

The private key is isolated during initialization, immediately removed from environment variables after loading, and automatically redacted in all logs. Console output and object sanitization mask sensitive fields.

Can I retrieve past thinking sessions?

Yes. Use the `listsessions` tool to see all stored sessions and the `getsession` tool to retrieve the full contents of a specific session, including a portal link to view it on the Recall network.

What credentials does it need?

It reads `RECALL_PRIVATE_KEY`, `RECALL_NETWORK`, `RECALL_BUCKET_ALIAS`, `RECALL_LOG_PREFIX` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Sequential Thinking MCP Server?

An MCP server that enables dynamic, reflective problem-solving by structuring thought processes and automatically logging each session to Recall.

The short version

An MCP server implementation that provides a tool for dynamic and reflective problem-solving through a structured thinking process which automatically writes sequential thinking logs to Recall associated with each thought session.

Step-by-Step Problem Solving —
Break down complex problems into manageable steps
Revise and refine thoughts as understanding deepens
Branch into alternative paths of reasoning
Adjust the total number of thoughts dynamically
Hypothesis Management —
