Settings and discovery

Glyphs MCP has two configuration surfaces:

  • Glyphs UI: Edit -> Glyphs MCP Server
  • Environment variables: optional security, docs, and debugging behavior

Tool discovery​

Glyphs MCP exposes one catalog-driven registry. The generated command set is the authoritative count and tool list. Clients that honor MCP Apps visibility omit app-only wrappers from model routing. Every tool carries four MCP safety hints plus effect and lifecycle metadata; there is no profile selector or saved profile state.

Environment variables​

GLYPHS_MCP_AUTH_TOKEN​

Require a static token on every request.

Accepted headers:

  • Authorization: Bearer <token>
  • mcp-auth-token: <token>

GLYPHS_MCP_ALLOWED_ORIGINS​

Restrict requests by hostname allowlist when an Origin header is present, in addition to default local hosts.

GLYPHS_MCP_REGISTER_DOC_PAGES​

Controls whether every bundled docs page is registered as its own resource.

  • Default: off.
  • Set to 1 only when you need per-page resources.

Prefer docs_search and docs_get for normal work.

GLYPHS_MCP_DOCS_URL​

Override the docs URL shown in the Glyphs MCP status panel.

Current public docs URL:

https://thierryc.github.io/Glyphs-mcp/

GLYPHS_MCP_EXTRA_SITEPACKAGES​

Colon-separated list of additional site-packages directories to add to sys.path.

Example:

export GLYPHS_MCP_EXTRA_SITEPACKAGES="/path/to/site-packages:/another/site-packages"

Use this only for debugging/import fixes.
