Overview

Description from the maker (original English)

Look up 133 agentic-web standards, live-probe any domain, validate manifests, generate boilerplate.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Docs, sheets & office work

Install

Pick the AI app you use, then copy the settings.

Before you install

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • define

    Define an agentic-web glossary term or standard by id, name, or alias. Returns { kind, id, name, definition_md, related_protocols, url } (or nearest-term hints on unknown-term error). Use define for concept definitions; use get when you need a standard's full specification record

  • get

    Fetch one standard's complete specification record by id, acronym, filename, or RFC number. Returns { id, name, step, status, governance, version, spec_url, probe, adoption, summary_md, url } (or unknown-id error with nearest matches). Use get for a known standard; use search to

  • search

    Search 132 standards and 52 glossary terms by keyword, acronym, alias, or 'A vs B' pair (pass q or alias query, 2–200 chars). Returns { results (top 10 ranked by title/alias/body match), matching_terms, comparison_url } or nearest_ids hints when empty. Use search for keyword disc

  • has

    Check one public origin over HTTPS for a single standard or manifest (rate-limited to 120/min). Returns { origin, id, found, outcome, status, url, reason, article } without grading the full site. Use has for a fast single-file check; use probe to scan all 37 paths at once, or val

  • probe

    Scan a public origin across 37 agent-facing paths and headers (24h KV cache by default; pass fresh: true to re-probe live with a 5-min per-origin cooldown, rate-limited to 30/min). Returns { found_ids, found, absent, coverage, extracted, connect_recipe }; pass brief: true for fou

  • changes

    List machine-verified specification changes since a YYYY-MM-DD date or ISO-8601 timestamp (newest first, default 50, max 200). Returns { since, count, entries: [{ date, record_id, field, old, new, source }] } filtered optionally by lifecycle step or record_id. Use changes for fie

  • stale

    List standards whose last_verified date is older than N days (default 30, oldest first), optionally filtered by lifecycle step. Returns { threshold_days, count, records: [{ id, name, step, last_verified, days_since_verified }] }. Use stale to audit verification freshness; use cha

  • validate_manifest

    Audit a public origin across 37 agent manifests (24h KV cache; fresh: true re-probes live with 5-min cooldown, 30/min limit) or validate local file text in-memory before deploy (pass id + content, no network fetch). Returns { grade (A+ to F), score, subscores, conformance_summary

  • template

    Generate in-memory starter boilerplate for any of the 12 supported manifest ids (ard, ai-catalog-well-known-file, llms-txt, agents-md, anthropic-agent-skills-format, mcp-server-cards, a2a, ai-crawler-tokens-robots, api-catalog-rfc9727, security-txt, auth-md, okf) without writing

  • ask

    Recommend and rank standards to implement for an engineering goal (pass question/q and/or use_case + audience filters), or compare named protocols head-to-head when the query names 2+ standards. Returns { use_case, audience, standards (ranked by tier and adoption), starter_bundle

  • digest

    Fetch the curated daily agentic-web news and adoption digest for a YYYY-MM-DD date (defaults to latest). Returns { date, headline, highlights, new_instances, spec_changes, stats }; pass list: true to return available dates only, or compact: true (alias: include_stats: false) to o

Common questions

Is Agentic Web Wiki — standards reference, probe, validate, template safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 14 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

agenticweb-data (wiki.agenticweb/probe)

Canonical Open Dataset, JSON Schemas, Bi-Temporal Change Log, Executable Probe Rules & Stateless MCP Server (`https://agenticweb.wiki/mcp`) for [`agenticweb.wiki`](https://agenticweb.wiki)

Maintained by Belgravia Labs LLC (info@belgravialabs.com), agenticweb-data is the verified, schema-enforced ground-truth repository powering agenticweb.wiki and its public Model Context Protocol (MCP) server `wiki.agenticweb/probe` at `https://agenticweb.wiki/mcp`.

Every merged commit on main is validated in CI against strict JSON Schemas and automatically ingested to rebuild the public registry (132 standards, 51 glossary terms, 151 head-to-head comparisons, 1,137+ probed origins) and the 11-tool stateless Streamable HTTP MCP server.


Connect to the MCP Server (https://agenticweb.wiki/mcp)

Quick Configuration (claude_desktop_config.json / .mcp.json / Cursor)
{

"mcpServers": { "agenticweb": { "type": "http", "url": "https://agenticweb.wiki/mcp" } } }

claude mcp add --transport http agenticweb https://agenticweb.wiki/mcp

Tools (tools/list & tools/call — 11 Tools)

All 11 tools are deterministic, read-only (readOnlyHint: true, destructiveHint: false, idempotentHint: true), and execute at the Cloudflare edge in <15 ms.

`changes`since: string, step?: string, record_id?: string, limit?: numberQuery machine-verified changelog diffs (old -> new, summary, evidence URL, date) since YYYY-MM-DD.
`stale`days?: number, step?: stringList standards whose last_verified date is older than days (default 30), optionally filtered by lifecycle step.
`digest`date?: string, list?: boolean, compact?: boolean, include_stats?: booleanFetch the daily Agentic Web Digest (date: "latest" or "YYYY-MM-DD"), list all published dates (list: true), or pass compact: true / include_stats: false to omit the stats block.
