Delx Agent Utilities MCP server

<!-- delx-utilities header v1 --> Delx Agent Utilities

Stateless utility tools for AI agents — URL/HTTP, DNS/RDAP, x402, JWT, encoding, parsing, regex, cron. Local-first. No API keys. Deterministic.

mcp-name: io.github.davidmosiah/delx-agent-utilities

What it is

89 stateless utility tools that AI agents reach for constantly: URL health checks, page extraction, MCP readiness, x402 server discovery, loyalty reward quotes, JWT inspection, DNS / RDAP lookups, JSON / CSV conversion, hash / base64, cron description, and more.

• Stateless — every call is independent; no session, no cache, no DB.
• No API keys — public endpoints only (rdap.org, dns.google, plus user-supplied URLs).
• Deterministic — no LLMs, no model calls, no fuzzy outputs.
• Fast — most tools < 100ms; networked tools < 5s with timeouts.
• MCP-native — agent-readiness manifest, connection status, privacy audit.

This package was extracted from the Delx Protocol MCP server so any AI builder can use the toolkit directly, without depending on the Delx runtime. The public product and protocol context lives at ontology.delx.ai/utilities.

HTTP (v2 stateless)

Not shipped. The Python FastMCP extra is stdio-only. Adding Streamable HTTP would need extra Starlette /health wiring beyond a one-flag opt-in, so it stays documented-skip (same for google-ads-intent-mcp). The tools themselves are already request-stateless.

Install

pipx install "delx-agent-utilities[mcp]"

CLI entrypoints: delx-agent-utilities, delx-utils (alias), delx-utils-mcp (MCP server).

Quick use

From an MCP client (Claude Desktop, Cursor, Hermes, OpenClaw)

{
  "mcpServers": {
    "delx-utils": {
      "command": "delx-utils-mcp"
    }
  }
}

90 tools become available immediately, plus three agent-readiness surfaces:

• delxutilitiesmanifest
• delxutilitiesconnection_status
• delxutilitiesprivacy_audit

From the CLI

delx-utils manifest
delx-utils list-tools
delx-utils show util_url_health
delx-utils call util_url_health --json '{"url":"https://example.com"}'

From Python

import asyncio
from delx_agent_utilities import call_util_tool, list_util_tool_schemas

result = asyncio.run(call_util_tool("util_url_health", {"url": "https://example.com"}))
print(result["status_code"], result["latency_ms"])

schemas = list_util_tool_schemas()
print(f"{len(schemas)} tools available")
