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.
codex_catalog_listList Codex Immortal products and services with pricing basis, capabilities, denied capabilities, and validation status.
codex_catalog_get_productGet the full ERC-8004-shaped service offer for one product: capabilities, pricing, SLA, refund/dispute terms, evidence and validation status.
codex_quote_requestRequest a quote for volume, enterprise, or custom-scope engagements. Returns an RFQ reference and expected response time.
codex_attestation_verifyVerify a Codex Immortal attestation record: content hash, signature, timestamp, and ledger inclusion proof.
codex_scan_requestRequest an autonomous threat-hunt scan (supply-chain, insider-threat, HNDL triage). Defensive and read-only by design. Live-scope scans route to human gate before execution.
codex_purchase_initiatePrepare a purchase proposal for a catalog item. Returns an AP2/x402 checkout payload draft for human approval. This tool never executes a payment, charges a card, or moves funds — execution happens only through the isolated financial connector gateway after a valid, exact-match,

Common questions
Is CodexImmortal 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 (1.1.0) reached the registry yesterday.
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?

Public agent-discovery and product documentation for CodexImmortal.
Buy with your agent
Ask your agent to inspect the CodexImmortal catalog, compare the products with your requirements, and return the appropriate one-time checkout link.
Buyer guide | Machine-readable catalog
Products and storefront checkout
This MCP server exposes the CodexImmortal storefront catalog; it is not a separate product catalog. The table below reflects catalog v1.2.4 and its $49–$449 pricing. Links open storefront product pages, where server-priced checkout is offered; they are not direct hosted Stripe payment links.
All prices below are one-time payments in USD, not subscriptions. Scope descriptions are merchant catalog descriptions, not independent verification of delivery. Confirm license, fulfillment, support, refund terms and any applicable tax before paying. One-time payment does not promise lifetime access or updates.
| Product | Stated scope | One-time USD | Storefront product page |
|---|---|---|---|
| AI Workflow Launch Kit | Core module map, activation checklist, workflow starter blueprint | $49 | View product |
| Decision Review Workspace | Council configuration with 250 decision cycles | $199 | View product |
| AI Implementation Blueprint | Implementation blueprint covering orchestration, operations, memory and governance | $149 | View product |
| MCP Integration Kit | SDK package and integration guide | $249 | View product |
| Agent Evaluation Lab | Lab configuration and 25 evaluations | $249 | View product |
| Revenue Operations Workspace | Ledger and receipt-proof workspace | $299 | View product |
| Agent Workflow Launch | Workflow build with five agents and 500 runs | $349 | View product |
| Security Hardening Package | Security and compliance posture package | $399 | View product |
| Agent Knowledge Hub | Graph deployment and 10,000 indexed records | $349 | View product |
| Bitcoin Transaction Controls | PSBT and multisig operations workspace | $399 | View product |
| Multi-Node Coordination Setup | Three-peer federation configuration | $449 | View product |
The prior $50–$5,000 catalog snapshot and its hosted buy.stripe.com links are retired from the current catalog. This documentation update does not deactivate any legacy Stripe links; any still-active legacy links require an owner audit in Stripe before deactivation. Opening a product page does not charge a customer; completing checkout can. Checkout availability is not proof that fulfillment or autonomous purchasing is implemented.
Agent surfaces
- Static catalog (primary, always on): https://calebfbyker-lab.github.io/codeximmortal-mcp/catalog.json
- Static buyer guide: https://calebfbyker-lab.github.io/codeximmortal-mcp/docs/buyer-guide.md
- Remote MCP wire endpoint: https://codeximmortal-mcp.onrender.com/mcp
- Health route: https://codeximmortal-mcp.onrender.com/healthz
The static surfaces are served by GitHub Pages and are always available. The MCP endpoint runs on a Render free-tier instance: it spins down when idle and may take time to wake; if it is unreachable, use the static catalog and this README. MCP wire methods are tools/list and tools/call. Catalog handlers are implemented locally; other tool handlers proxy to a separately configured gateway. Catalog JSON (v1.2.4) embeds a storefront product-page checkout_url for each offer; the table above mirrors those links. The buyer guide is a separate document and has not been reverified for catalog alignment in this update.
Tool status
| Tool | Implementation status |
|---|---|
| codex_catalog_list | Live end-to-end tools/call verified on November 7, 2026 with category=all; returned catalog v1.2.4 with 11 offers and no MCP tool error |
| codex_catalog_get_product | Local product handler; end-to-end verification pending |
| codex_quote_request | Gateway-dependent; not verified operational |
| codex_attestation_verify | Gateway-dependent; not verified operational |
| codex_scan_request | Gateway-dependent; not verified operational |
| codex_purchase_initiate | Gateway-dependent; no verified autonomous live payment execution |
The catalog-list test verifies retrieval for the tested request, not every category filter, checkout execution, fulfillment, or merchant claims.
Governance and release status
UNCERTIFIED. CI-059 dependency is PROVISIONAL; CI-043 status is Active according to project instructions, not a fresh registry audit. No payment credentials belong in this repository or agent prompts. Automated financial execution remains disabled; storefront checkout is a separate payment surface. This repository does not establish AP2, ACP, x402 or A2A runtime compatibility, government authorization, security certification, or guaranteed revenue.
Distribution
Published in the official MCP Registry as io.github.calebfbyker-lab/codeximmortal, version 1.1.0. The registry response checked on November 7, 2026 reports status active, isLatest: true, and publication at 2026-11-07T15:03:51.99961Z.
Registry lookup: https://registry.modelcontextprotocol.io/v0/servers?search=codeximmortal
The live remote endpoint passed MCP initialization and tools/list, returning all six advertised tools on November 7, 2026. A subsequent tools/call to codex_catalog_list with category: all returned catalog v1.2.4 with 11 offers and no MCP tool error. Other tool invocations remain unverified. Registry publication is a discoverability milestone, not security certification, government endorsement, or verification of payment functionality.
