From the repository
``bash``
npx -y @aimino/fast-html-mcp-server
Or add to your MCP client config:
render_page
Assemble page from structured components
patch_html
Patch HTML element(s) by CSS selector
set_attribute
Set attribute on element(s) by CSS selector
edit_html_range
Replace a range of lines in an HTML file with new content (most token-efficient edit — send only the changed lines)
edit_section
Replace a rendered section in an HTML file with a new component. Pages rendered with render_page embed section markers. Use list_sections to discover available indices. Provide component+props to re-render, or html for raw replacement.
insert_section
Insert a new component section at a specific index, pushing existing sections forward. Uses the same section marker system as render_page. Auto-renumbers all subsequent sections.
list_sections
List all component sections in an HTML file that was built with render_page. Returns section indices, component types, and sizes.
read_html
Read/analyze existing HTML file. Use mode='text' for token-efficient plain text extraction with offset/limit progressive reading.
write_raw_html
Write raw HTML content directly to file
write_html_file
Write content as formatted HTML file
format_html
Format/beautify an existing HTML file
preview_html
Preview rendered HTML string without writing
list_templates
List available template shells (optionally filter by category)
propagate_edit
Propagate an entity edit through the dependency graph, updating all transitively affected sections
check_consistency
Audit document for stale cross-section references and dependency violations
list_components
List available interactive components (optionally filter by category)
get_template_schema
Get template metadata including available variables with defaults
get_component_schema
Get component schema with available props
register_template
Register a custom template at runtime for immediate use with render_page/preview_html
