CockroachDB Plugin for Claude Code connects Claude Code to CockroachDB clusters, which are distributed databases, so the agent can work with schemas, SQL queries, and database operations. It is intended for developers, database administrators, and operators working with self-hosted or CockroachDB Cloud deployments. The catalogue entries provide its MCP connections, specialized agents, skills, and safety hooks.
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 | $0.00079 | $0.02733 |
| Opus 5.5 | $0.00032 | $0.01093 |
| Sonnet 5.5 | $0.00016 | $0.00547 |
| Haiku 4.5 | $0.00008 | $0.00273 |
Grade B, and why
upgrading-cluster-version scanned grade B with 2 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 2mo 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Upgrading Cluster Version
Guides CockroachDB version upgrades end-to-end. Before providing procedures, this skill gathers deployment context to deliver only the steps relevant to the operator's tier.
When to Use This Skill
- Planning or executing a version upgrade (Self-Hosted)
- Initiating a major version upgrade via Cloud Console (Advanced, BYOC)
- Configuring how patches are applied (Advanced, BYOC)
- Verifying upgrade completion (all tiers)
- Deciding whether to finalize or roll back (Self-Hosted)
For pre-upgrade health check: Use reviewing-cluster-health. For node drain during Self-Hosted upgrade: Use performing-cluster-maintenance. For maintenance window configuration: Use performing-cluster-maintenance.
Step 1: Gather Context
Required Context
| Question | Options | Why It Matters |
|---|---|---|
| Deployment tier? | Self-Hosted, Advanced, BYOC, Standard, Basic | Completely different upgrade procedures per tier |
| Current version? | e.g., v24.2.5 | Validates upgrade path and compatibility |
Additional Context (by tier)
If Self-Hosted:
| Question | Options | Why It Matters |
|---|---|---|
| Upgrade type? | Major (e.g., 24.2→24.3), Patch (e.g., 24.2.5→24.2.8) | Major requires finalization; patches do not |
| Target version? | e.g., v24.3.1 | Confirms version is available and sequential |
| Deployment platform? | Bare metal, VMs, Kubernetes (Operator/Helm/manual) | Changes binary replacement and restart procedure |
| Process manager? | systemd, manual, container orchestrator | Changes stop/start commands |
| Node count? | Number | Affects upgrade sequencing |
If Advanced or BYOC:
| Question | Options | Why It Matters |
|---|---|---|
| Upgrade type? | Major version, Patch | Major requires Console initiation; patches use maintenance windows |
| Cloud provider? (BYOC only) | AWS, GCP, Azure | For infrastructure-level monitoring during upgrade |
| Release channel? | Regular, Innovation | Innovation gives latest features, shorter support window |
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.

upgrading-cluster-version is a skill published in the GitHub repository cockroachdb/claude-plugin (4 stars, last pushed 28d ago), licensed Apache-2.0. It adds 79 tokens to every session and 2,733 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, makes network calls). It is 100% identical to upgrading-cluster-version, differing in 0 lines, and is treated as a copy.
