Install

How do I install the seekrit (local crypto plane) MCP server?

seekrit (local crypto plane) runs locally as an npm package, launched with npx -y @seekrit/mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 49 exposed · ~3,225 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Fork an environment into an ephemeral branch (a per-PR / preview config). The branch inherits the parent's secrets by layering at read time — nothing is copied or re-encrypted — and holds only the values you override on it. Generates the branch's data key locally, grants it to the caller, and shares it with the parent's other readers.

Mint a short-lived MySQL/MariaDB credential against a target and return a ready-to-use connection URL.

The user auto-expires; revoke early with revoke_mysql_lease.

create_pg_lease ~124

Mint a short-lived Postgres credential against a target and return a ready-to-use connection URL.

Mint a service token, printed once. Runtime tokens bind to one app environment (auto-granted its keys, so a command/agent can decrypt it). Pass admin:true for an org-scoped provisioning token (create apps/groups/envs, grant, mint tokens) — admin tokens need no env binding.

get_secret ~209

Return one secret. By default only reports presence + version; pass reveal:true to decrypt the plaintext into this response (avoid unless the value is actually needed — prefer run_command). A revealed current value has its ${OTHER_SECRET} references expanded against this environment's own secrets; pass raw:true for the stored text instead. Pass `version` to read an earlier version instead of the current one (always as stored, never expanded).

NameTypeReqDescription
appstring–application slug or id (or set via configure_project)
envstring–environment slug or id (a service token infers its own)

get_started ~34

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

grant_env ~142

Grant a member (by email) or service token (by id) access to an environment's data key. Re-wraps the DEK to the grantee — the caller must already hold the key.
