Connect an agent

Streamable HTTP: https://agent-tools-mcp.yvan11.workers.dev/mcp

Claude Code:

claude mcp add --transport http agent-tools https://agent-tools-mcp.yvan11.workers.dev/mcp

VS Code / Copilot: Command Palette → MCP: Add Server → HTTP → paste the endpoint URL.

Portable MCP configuration (VS Code/Copilot compatible):

{ "mcpServers": { "agent-tools": { "type": "http", "url": "https://agent-tools-mcp.yvan11.workers.dev/mcp" } } }

Use an MCP client rather than a browser GET request to /mcp, which can return Method not allowed by design.

Security and publishing

This is a public endpoint without authentication. Never submit real passwords, payment-card data, tax identifiers, bank information, private documents, or API secrets. Synthetic generated IDs and seeded passwords are development fixtures only. Read SECURITY.md.

The repo is public and MIT licensed, preserving the vendored source licenses. Cloudflare Workers Builds tests and deploys on commits to main; no GitHub Actions. The official registry descriptor uses io.github.why-see/agent-tools-mcp; Glama metadata identifies the maintainer. These files do not automatically publish a registry listing.

Validators (12): is-card-safe, is-email-safe, is-iban-safe, is-iso-date-safe, is-ip-safe, is-json-safe, is-password-safe, is-phone-e164, is-uuid-safe, is-url-safe, is-us-tin-safe, is-vat-safe.

Optimizers (7 tools / 6 modules): is-dataset-minify, is-google-tag, is-html-minify, is-minify-js, is-minify-css, is-prompt-minify, is-strip-ansi.

Generators (13): generate-avatar, generate-card-number, generate-color, generate-dataset, generate-fake-data, generate-hash, generate-lorem, generate-password, generate-phone-number, generate-prompt, generate-slug, generate-ssn, generate-token.

Names and implementations are derived from the upstream module files. Exact upstream versions and update policy are documented in UPSTREAM.md. The upstream catalogs are not complete or consistent enough to serve as the runtime source of truth; we use explicit audited function adapters.

Tests and deployment

On GitHub, push to main → Cloudflare Workers Builds performs npm test, then npx wrangler deploy only if tests pass. No GitHub Actions are present.

The test suite invokes all 32 MCP tools through the actual handler, including the initialize, tools/list, and tools/call protocol methods.

The Worker has a Cloudflare native rate-limit binding (30 requests per minute per IP per data center), 8-KiB body guard and per-tool input/output bounds.

Optional MCP_API_TOKEN must be a Cloudflare secret, not a GitHub secret or a variable in wrangler.toml.

Restrictions

This public endpoint runs pure software utilities and cannot access your GitHub, Cloudflare, OpenAI or payment accounts. It is not a remotely editable filesystem. Do not send real passwords, payment details or private personal data to its validators. Generated financial identifiers and SSNs are synthetic test fixtures only. This service does not provide OAuth, client billing, SLA, global quotas or user identity.

Current catalog size is 32 MCP tool names backed by 31 original upstream modules. An update to an upstream source repo does not automatically rebuild this MCP Worker; see the explicit update policy.
