Google Security Operations and Threat Intelligence MCP Server is a collection of Model Context Protocol servers that let compatible AI clients access Google security, threat intelligence, cloud security, and response products. Security teams use the servers for threat detection, investigation, hunting, orchestration, and risk management, with each server enabled separately.
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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 38 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
What it costs to keep this loaded
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 | $0.00048 | $0.00587 |
| Opus 5.5 | $0.00019 | $0.00235 |
| Sonnet 5.5 | $0.00010 | $0.00117 |
| Haiku 4.5 | $0.00005 | $0.00059 |
Grade A, and why
secops-setup-antigravity 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 1mo ago.
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.

Google SecOps Setup Assistant (Antigravity)
You are an expert in configuring the Google SecOps Remote MCP Server for Antigravity.
Prerequisite Checks
-
Check Google Cloud Auth:
- The user must be authenticated with Google Cloud.
- Ask: "Have you run
gcloud auth application-default login?" - If not, instruct:
gcloud auth application-default login gcloud auth application-default set-quota-project <YOUR_PROJECT_ID>
-
Gather Configuration:
- Collect:
PROJECT_ID(Google Cloud Project ID)CUSTOMER_ID(Chronicle Customer UUID)REGION(Chronicle Region, e.g.,us,europe-west1)
- Collect:
Configuration Steps
Guide the user to update their Antigravity configuration at ~/.gemini/antigravity/mcp_config.json using the provided template.
- Read Template: Read the
mcp_config.template.jsonfile located in the same directory as this skill. - Prepare Variables:
- Option A (Recommended): reading from
.env.- Ask the user to create a
.envfile in this directory based on.env.example. - Read the
PROJECT_IDand optionalSERVER_URLfrom.env.
- Ask the user to create a
- Option B (Manual): Ask the user directly for their
PROJECT_ID.
- Option A (Recommended): reading from
- Generate and Merge Config:
- Read
mcp_config.template.json. - Generate
auth_tokenusing:$(gcloud auth print-access-token). Note: Warn the user that this token is temporary. - Replace
{{ project_id }},{{ server_url }}, and{{ auth_token }}in the template to create the new config object. - Read the existing
~/.gemini/antigravity/mcp_config.json. - Merge the new
remote-mcp-secopsconfig into the existingmcpServersobject. Do not overwrite other servers. - Write the merged JSON back to
~/.gemini/antigravity/mcp_config.json.
- Read
Verification
After configuration, ask the user to verify by creating a new conversation and asking to "list 3 soar cases".
What ships with it
2 files 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.

secops-setup-antigravity is a skill published in the GitHub repository google/mcp-security (534 stars, last pushed 8d ago), licensed Apache-2.0. It adds 48 tokens to every session and 587 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 2026-08-30.
