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 | $0.00095 | $0.03420 |
| Opus 5.5 | $0.00038 | $0.01368 |
| Sonnet 5.5 | $0.00019 | $0.00684 |
| Haiku 4.5 | $0.00010 | $0.00342 |
Grade A, and why
managing-cluster-capacity scanned grade A with 1 finding 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.

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

Managing Cluster Capacity
Manages cluster capacity across all CockroachDB deployment tiers. What "capacity" means varies by tier — Self-Hosted manages individual nodes, Advanced/BYOC manage node count and machine size, Standard manages provisioned vCPUs, and Basic auto-scales with cost controls.
When to Use This Skill
- Permanently removing a node from a cluster (Self-Hosted)
- Adding nodes to increase capacity (Self-Hosted)
- Scaling cluster node count or machine size (Advanced, BYOC)
- Adjusting provisioned compute (Standard)
- Managing costs on a serverless cluster (Basic)
- Replacing hardware or migrating infrastructure (Self-Hosted, BYOC)
- Replacing a failed or dead node (Self-Hosted)
- Managing storage utilization and disk pressure (Self-Hosted)
For temporary maintenance (not capacity changes): Use performing-cluster-maintenance. For pre-operation health check: Use reviewing-cluster-health.
Step 1: Gather Context
Required Context
| Question | Options | Why It Matters |
|---|---|---|
| Deployment tier? | Self-Hosted, Advanced, BYOC, Standard, Basic | Different capacity model per tier |
| Direction? | Scale up (add capacity), Scale down (reduce capacity) | Determines procedure |
Additional Context (by tier)
If Self-Hosted (scaling down):
| Question | Options | Why It Matters |
|---|---|---|
| How many nodes to remove? | 1, multiple | Multi-node decommission should be done simultaneously |
| Target node IDs? | Node IDs from cockroach node status |
Required for CLI commands |
| Is the node alive or dead? | Alive, Dead | Dead nodes use a different procedure |
| Deployment platform? | Bare metal, VMs, Kubernetes | Changes CLI and cleanup steps |
| Current replication factor? | 3, 5, custom | Must have enough nodes remaining |
| Current node count? | Number | Validates remaining capacity |
| Storage utilization? | Low (<60%), Medium (60-80%), High (>80%) | Determines urgency and whether storage maintenance is needed |
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.

managing-cluster-capacity is a skill published in the GitHub repository cockroachdb/claude-plugin (4 stars, last pushed 28d ago), licensed Apache-2.0. It adds 95 tokens to every session and 3,420 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to managing-cluster-capacity, differing in 0 lines, and is treated as a copy.
