GitHub MCP Server is GitHub's official Model Context Protocol server, which lets AI tools interact with GitHub repositories and development data. It is used to browse code, manage issues and pull requests, inspect automation runs, review security findings, and support other repository workflows through natural-language requests. The catalogue add-ons connect coding agents to these GitHub capabilities.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.01240 |
| Opus 5.5 | $0.00023 | $0.00496 |
| Sonnet 5.5 | $0.00012 | $0.00248 |
| Haiku 4.5 | $0.00006 | $0.00124 |
Grade A, and why
security-alert-triage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Triaging security alerts
Turn four separate alert streams into one ordered list of decisions, each backed by evidence a maintainer can check.
This server reads alerts; it does not resolve them. No tool here dismisses an alert, merges a fix, or revokes a credential. The output is a recommendation with evidence.
Sequence
- Inventory every source that answers.
list_code_scanning_alerts,list_dependabot_alertsandlist_secret_scanning_alertswithstate: open. Enumeratelist_repository_security_advisoriesseparately: omitstatefor all advisories, or usetriage,draft,publishedorclosed. Record which sources answered and which did not — the difference matters, see the failure cases. When the question spans an organisation rather than one repository,list_org_repository_security_advisorieswithorggives the same advisory picture across every repository in it, and is the right starting point before fanning out. - Handle secret scanning first, ahead of any ordering by severity. A live credential is the only alert type where delay keeps causing harm.
- Order the rest by exploitability, not by count.
severitynarrows the field; whether the code is reachable decides it. - Read the individual alert for anything you intend to recommend on:
get_code_scanning_alert,get_dependabot_alertorget_secret_scanning_alertwith the alert number. List responses are deliberately thin. - Ground it in the code. For a code scanning alert, read the flagged location
with
get_file_contents. For a dependency alert,search_codefor the vulnerable symbol to find out whether the project reaches the affected path at all. - Look up the advisory behind a dependency alert with
list_global_security_advisoriesorget_global_security_advisoryby GHSA or CVE id. The advisory carries the patched versions and the real-world conditions. - Recommend, using the decision points below, naming the evidence each recommendation rests on.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

security-alert-triage is a skill published in the GitHub repository github/github-mcp-server (34,473 stars, last pushed yesterday), licensed MIT. It adds 58 tokens to every session and 1,240 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-11-14.
