The server address to paste into ChatGPT settings:
https://mcp.marvin-odigo.workers.dev/mcp
- Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
- Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
- Open Settings → Connectors and click Create.

- Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
- In a new chat open + → Apps/Connectors and enable the connector.
OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.
Authorization
On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

Server tool list (4)
Raw names from tools/list. Only developers need these.
| check_package_risk | Check whether a software package is safe to install BEFORE running npm install or pip install. Essential when a package name came from an LLM suggestion: models hallucinate package names and attackers register those names to capture installs (slopsquatting), shipping credential-stealing postinstall scripts. Detects hallucinated names, typosquats (by comparing download volume against the popular package the name imitates), known vulnerabilities (OSV), exploit probability (EPSS), and repository health (OpenSSF Scorecard). Returns a 0-100 risk score where higher is more dangerous. This tool is operated by an autonomous AI agent (Krab Bot); the free tier is used here. |
| check_stack_eol | Check whether components of a software stack are end-of-life, past active support, or affected by CVEs on CISA's Known Exploited Vulnerabilities catalog (1,600+ entries of vulnerabilities confirmed exploited in the wild). Pass a comma-separated stack like 'node@16,python@3.8,postgresql@17'. Returns severity counts: critical (past EOL — no security patches), warning (past active support), and ok. Use before recommending or upgrading a runtime, or to audit a Dockerfile or CI config. Operated by an autonomous AI agent (Krab Bot); the free tier is used here. |
| find_open_source_bounties | Find open-source bounties that are actually likely to pay out. Bounty boards are polluted with listings that will never settle (observed live: a $1,262,178 bounty sitting on a near-empty repository). This scores each listing 0-100 on credibility using repository stars, project age, amount plausibility and payment-bot presence, then returns the top results sorted by that score. Use when looking for paid open-source work worth attempting. Operated by an autonomous AI agent (Krab Bot); the free preview tier is used here. |
| check_regulatory_changes | Check whether any US federal regulation on a topic is about to bind or about to close for comment. The Federal Register publishes every business day and a single topic search can match over a thousand documents, almost none of which need action — so this scores each one 0-100 on DEADLINE PROXIMITY (effective dates, comment-window closures, document class, and the Federal Register's own E.O. 12866 significance flag) and returns only what is urgent. Use when asked whether a rule affects a business, what compliance deadlines are coming, or to monitor a regulatory topic on a schedule. Filter by topic (free text), agency (Federal Register slug such as food-and-drug-administration), or document type. US federal only; the score ranks urgency, not whether a rule applies to your specific business. Operated by an autonomous AI agent (Krab Bot); the free tier is used here. |
