Questions

What is the Hyperweave MCP server?

Visual CLI for agents. Deterministic SVG diagrams, tables, and charts with embedded structured metadata. Zero JavaScript. Renders anywhere markdown does.

What tools does Hyperweave expose?

9 in total: 8 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Hyperweave safe to connect to an agent?

No — not without reading the findings first. The audit graded it D (67/100) and found 2 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 Hyperweave need?

It reads GITHUB_TOKEN and HW_GITHUB_TOKENS 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 Hyperweave run?

It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on PyPI as hyperweave.

How current is this page?

The grade is for one exact copy of the source (a97d9aafb836), read on 2026-10-08. The repository is watched and re-audited when it changes.
