Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http payload-validator https://elyreon-payload-validator.colt2822.workers.dev/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "payload-validator": {
      "url": "https://elyreon-payload-validator.colt2822.workers.dev/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is ELYREON JSON Schema Payload Validator safe?

It passed 0 of 1 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?

You need to fill in: Authorization

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 (1.0.1) reached the registry 12 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?

ELYREON Payload Validator

Small, deterministic first-party distribution test in the existing public Decision Gateway repository. This isolated Worker validates JSON against an explicitly bounded JSON Schema 2020-12 subset. It does not call Nace.AI, expose Drex inference, execute uploaded code, or accept payments.

Endpoint: https://elyreon-payload-validator.colt2822.workers.dev

MCP: append /mcp. Get a free bearer token at POST /trial with JSON {"source":"github"}; send {"test":true,"source":"github"} for controlled evaluations. Configure the bearer header in any Streamable HTTP MCP client, discover validate_payload, and call with {schema,payload}. Direct HTTP uses POST /validate with the same token and input.

Install the Agent Skill in the client's skill directory. Portable git install:

git clone --depth 1 https://github.com/colt2822/Drex-Decision-Gateway-for-Coding-Agents.git

mkdir -p ~/.agents/skills/elyreon-payload-validator cp Drex-Decision-Gateway-for-Coding-Agents/distribution/payload-validator/skills/elyreon-payload-validator/SKILL.md ~/.agents/skills/elyreon-payload-validator/

Limits: 32 KiB request, depth 12, 2048 values, 128 schema nodes, 3-second body timeout; one validation error. Free quota: 20 invocations/token/day, 1000 invocations/service/day, 100 enrollments/service/day, 5 enrollments/IP/hour; edge limit 30 requests/IP/minute/location. Schema references, regex, formats and combinators are rejected. Supported keywords are documented in the skill. Validation does not certify runtime behavior. Malformed/unsupported input returns REJECTED; invalid data returns completed FAIL.

Deployment has a separate Worker and D1 database, no custom routes or other production bindings. Worker stores no input bodies, schemas or raw IPs. Token hashes and usage metadata are retained 30 days. Source is client-claimed; tokens are not verified customers. PHOENIX monitoring uses its existing controller timer and CRM; all five seats remain intact. Controlled tests are marked synthetic. No outbound sender or payment system is invoked. Provider inference cost is zero; hosting costs require billing evidence.

server.json is Official MCP Registry metadata. /.well-known/ai-catalog.json is a self-hosted catalog, not proof of a third-party listing. /x402-bazaar.json is inactive draft metadata with no accepted payment methods; it is not a paid Bazaar listing.

Validation: npm ci, npm test, python3 tests/reference_check.py, python3 -m unittest discover -s tests -p 'test_monitor.py', npm run dry-run. Local HTTP acceptance uses wrangler d1 execute elyreon-payload-validator --local --file migration.sql, then wrangler dev --port 18741 --var PRIVACY_SALT:local-only --var SYNC_TOKEN:local-only, then python3 tests/http_check.py.

Deploy with npm run deploy only to the named isolated Worker, preserving secrets. Roll back using wrangler rollback VERSION_ID; for the first deployment, disable only this Worker's workers.dev endpoint. Never change existing website routes. Secrets SYNC_TOKEN, TEST_TOKEN and PRIVACY_SALT are kept outside git. Registration authentication files must remain outside git.

The Official MCP Registry listing is co.com.elyraon/payload-validator version 1.0.0. Registry readback, clean public installation and MCP acceptance, and receipt attribution are recorded separately. This is controlled evidence, with zero independent customers or revenue.

VS Code MCP configuration prompts privately for the free token. The generic Agent Skill can also be installed in clients that read SKILL.md; no native VS Code GUI or other desktop client acceptance is claimed. Default Python urllib requests are blocked by Cloudflare error 1010; the standard MCP Python SDK, httpx and curl succeeded. No Cloudflare security setting was changed.

The PHOENIX monitor runs as an error-isolated post-command on the existing controller service, throttled to one network pass per 15 minutes. It records readback, usage, repeat tokens, per-seat responsibilities and explicit unknown hosting cost in the existing CRM. It reads existing demand feeds and never sends messages. See the systemd drop-in. Synthetic tests remain excluded from customer and installation totals.
