Questions

What is the @theokit/sdk MCP server?

Open-source TypeScript SDK and agent runtime you own end to end. Agent.create / prompt / stream / resume, 43 LLM providers on your own keys, MCP with OAuth PKCE, subagents, workflows, evals, memory, and a bubblewrap+seccomp kernel sandbox for tool execution. Local-first, opt-in cloud, Apache-2.0.

What tools does @theokit/sdk expose?

112 in total: 99 read-only, 13 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is @theokit/sdk safe to connect to an agent?

No — not without reading the findings first. The audit graded it F (29/100) and found 8 critical or high issues in the source. Each one is listed on this page with the file and line it is on.

What credentials does @theokit/sdk need?

It reads ANTHROPIC_API_KEY, AWS_ACCESS_KEY_ID, AWS_BEARER_TOKEN_BEDROCK, BRAVE_API_KEY, FIXTURE_SEARCH_TOKEN, GOOGLE_APPLICATION_CREDENTIALS, HONCHO_API_KEY, MCP_LEAK_TOKEN, MEM0_API_KEY, MY_OVERRIDE_KEY, OLLAMA_API_KEY and OPENAI_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does @theokit/sdk run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as simple-node-project.

How current is this page?

The grade is for one exact copy of the source (87e84fd306ad), read on 2026-10-12. The repository is watched and re-audited when it changes.
