material-web-mcp
Provides programmatic access to Material Web documentation and components for AI agents, enabling documentation search, template generation, and HTML validation.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
list_componentsReturns a JSON array of available Material Web component names
search_docsSearches Material Web documentation for a keyword and returns matching file paths with excerpts
health_checkPerforms a health check on the server, verifying uptime, documentation accessibility, and basic functionality
get_component_docReturns the full documentation for a specific Material Web component
get_theming_docsReturns the theming documentation for Material Web
get_installation_docsReturns the installation and quick-start documentation for Material Web
validate_websiteValidates HTML code for correct Material Web component usage
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
7/7 tools missing one or more hints — list_components (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_docs (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); health_check (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 3/7 tool handlers declare input schemas (43%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
6/7 tool handlers wrap calls in try/catch (86%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.20.0 (high), @modelcontextprotocol/sdk@1.20.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
