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 | $0.00061 | $0.02591 |
| Opus 5.5 | $0.00024 | $0.01036 |
| Sonnet 5.5 | $0.00012 | $0.00518 |
| Haiku 4.5 | $0.00006 | $0.00259 |
Grade A, and why
managing-tls-certificates 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 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.
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.
This is a copy
100% identical to managing-tls-certificates — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Managing TLS Certificates
Manages TLS certificates for CockroachDB clusters, covering CA certificate downloads, client certificate authentication setup, certificate rotation, and troubleshooting common SSL/TLS connection errors. Addresses both CockroachDB Cloud (always-on TLS) and self-hosted certificate lifecycle management.
When to Use This Skill
- Troubleshooting SSL/TLS connection errors from application clients (DBeaver, TypeORM, psql, Go, Python, Java)
- Setting up client certificate authentication on CockroachDB Cloud
- Uploading a custom Client CA to a Cloud cluster
- Rotating or renewing certificates (Cloud or self-hosted)
- Configuring mTLS for CDC changefeeds to Kafka
- Downloading or locating the CA certificate for a Cloud cluster
Prerequisites
CockroachDB Cloud:
- ccloud CLI authenticated (
ccloud auth login) - Cloud Console access for CA certificate download
- Cluster Admin role for client CA configuration
Self-hosted:
- cockroach cert CLI available
- Admin access to cluster nodes
- OpenSSL for certificate inspection and generation
Verify access:
# Cloud
ccloud auth whoami
ccloud cluster list
# Self-hosted — check existing certificates
cockroach cert list --certs-dir=<certs-directory>
Configuration Decisions
Before proceeding, determine the user's deployment model. Ask which option applies, then follow only the relevant sections below.
Decision 1 — Deployment model:
- CockroachDB Cloud: TLS is always on and the cluster CA is managed by Cockroach Labs. Follow Part 1 for CA download, client certificate auth, and Cloud certificate rotation.
- Self-hosted: Full manual certificate lifecycle management (CA, node, and client certificates). Follow Part 2 for certificate creation, rotation, and management.
Parts 3 (Troubleshooting) and 4 (mTLS for CDC) apply to both deployment models.
Steps
Part 1: CockroachDB Cloud TLS
Follow this part if the user selected CockroachDB Cloud in Decision 1.
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.
