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 | $0.00096 | $0.01155 |
| Opus 5 | $0.00048 | $0.00577 |
| Sonnet 5 | $0.00019 | $0.00231 |
| Haiku 4.5 | $0.00010 | $0.00115 |
Grade A, and why
cb-analytics-security 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Couchbase RBAC via cb-analytics-mcp
You have 9 RBAC tools: list/get/upsert/delete user, list/upsert/delete group, list roles, and check permissions.
The two domains
Couchbase users live in one of two domains:
- local — created and managed inside Couchbase itself.
- external — authenticated via LDAP / SAML / PAM, mirrored locally with role bindings.
Every user-related tool takes a domain argument. If you list users without
a domain you get both.
Role-spec format
roles is a single comma-separated string, never a list. Each role can be
unscoped or scoped:
analytics_reader[*] # all buckets
analytics_select[bucket1] # one bucket
analytics_select[bucket1:scope1] # one scope
analytics_admin[*],query_select[bucket1] # multiple roles
Use list_roles() first if you don't know what's available — it returns
every role the cluster supports, with descriptions.
Creating a service account
For Claude itself, or any automation, create a least-privileged user:
upsert_user(
domain="local",
username="cb-mcp",
roles="analytics_reader[*],analytics_select[*]",
password="<generated>",
full_name="cb-analytics-mcp service account"
)
Never use analytics_admin or cluster_admin for the MCP server's
cluster credentials in production. Grant only what the workflow needs.
Password handling
The password is passed as a plain string into the tool and immediately
wrapped in SecretStr inside the impl, then unwrapped only at the HTTP
boundary. The audit log redacts it. That said:
- Generate strong passwords (
secrets.token_urlsafe(32)). - Rotate by calling
upsert_useragain with a newpassword. - Never echo a password back to the user in chat.
Checking permissions
check_permissions(permissions="cluster.analytics!read,cluster.admin!write")
returns a dict mapping each permission to true/false for the currently
authenticated user (the one in CB_ANALYTICS_USERNAME). Use this when:
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.

cb-analytics-security is a skill published in the GitHub repository celticht32/Couchbase-Skills-for-Claude.ai (4 stars, last pushed 2mo ago), licensed MIT. It adds 96 tokens to every session and 1,155 once invoked, about $0.0005 per session on Opus 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 2026-08-31.
