lizard-core

A guide for managing applications and managed databases on the Lizard cloud platform. It explains how workspaces, projects, and deployable services are organized.

In plain words
What is it for?
Deploying GitHub repositories, creating PostgreSQL, Redis, or S3 services, checking logs and events, managing environment settings, scaling services, and running shell commands.
Why use it?
It helps an agent deploy and operate cloud services while using the correct resource structure and deployment limits. It also documents how to manage logs, secrets, domains, scaling, and related services.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

lizard-core 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 2d 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.

The opening of the file, as written. The whole thing — 259 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Lizard platform

Lizard is a unified cloud for apps, services, agents, and managed databases. This MCP server exposes the whole platform through 33 tools — deploy a GitHub repo, provision managed Postgres/Redis/S3, and manage logs, metrics, secrets, domains, scaling, and shell exec — scoped to the caller's own workspaces and projects.

Mental model

workspace -> project -> service (app or addon)
  • Workspace — account/org level. A user belongs to one or more (workspace_list).
  • Project — a group of related services in one workspace (project_list, project_create).
  • Service — a deployable unit. Every app deploys from a GitHub repo (service_create with repoUrl) or starts empty and gets a source wired in later (service_set). There is no local tarball-upload path here — unlike the lizard CLI's lizard up, this MCP server can only deploy from a git repo URL, since it has no access to the user's local filesystem.
  • Managed addons — postgres, redis, s3 (addon_create). See Managed addons for each type's env vars.
  • Cross-resource refs — ${{<name>.<KEY>}} resolves at deploy time against the target's merged env. A ref to a missing target or key resolves to an empty string rather than failing the deploy (only circular refs throw). After wiring one, verify the consumer actually got a value — logs_tail or ssh_exec -- env. Stored form is ID-based, so renaming an addon later doesn't break existing refs.

Most tools take a project (name/slug/ID) and service (name/ID) param, resolved by exact name match, not fuzzy — call workspace_list / project_list / service_list first if unsure which one the user means.

No local repo access

Unlike the lizard CLI or a coding agent working in the user's own checkout, this MCP server never sees the user's files. It cannot read package.json, a Dockerfile, or check for a git remote. That means:

  • Ask the user for the repo URL, branch, and any build/start command instead of inferring them from local files.
  • Rely on the platform's own build auto-detection (lizardpack) for common stacks (Go, Node, Python, Rust, Ruby, PHP, Java, static) rather than guessing a buildCommand / startCommand up front — only set those fields if the user states them, or a build actually fails without them.
  • If a build fails, read deploy_events / logs_tail for the real error before proposing a fix.

Files

What ships with it

1 file 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.

Changes

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.

lizard-core is a skill published in the GitHub repository lizard-build/lizard-mcp (0 stars, last pushed 3d ago), licensed MIT. It adds 194 tokens to every session and 3,427 once invoked, about $0.0010 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.
