string-ai-mcpSAFE
Model Context Protocol server for the Web Access API.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
The official Model Context Protocol (MCP) server for String AI's Web Access API. Search the web, fetch any URL or send it a request, and map a site's URLs — all returned as clean, LLM-ready Markdown. Connect any MCP-compatible client — VS Code, Cursor, Windsurf, Claude Desktop, and more.
Tools
web_access_fetch, web_access_search, and web_access_product_help are read-only. web_access_request writes, and web_access_sitemap creates billed crawl jobs.

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control. Replace the environment placeholders with a token scoped to the least it needs.

Questions
What is the string-ai-mcp MCP server?
Model Context Protocol server for the Web Access API.
What tools does string-ai-mcp expose?
5 in total: 5 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is string-ai-mcp safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does string-ai-mcp need?
It reads STRING_AI_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 string-ai-mcp run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as @usestring/mcp at 1.3.8.
How current is this page?
