Agent Skills

View as Markdown

Coding agents like Claude Code, Codex, Cursor, and others can work with Materialize using our open-source agent skills. Once installed, these skills give your coding agent access to Materialize documentation and reference material so it can provide more accurate assistance when writing queries, setting up sources, creating materialized views, and more.

Skills

Skill What it provides When to use
mcp-developer-analysis Exact catalog schemas, diagnostic workflows, remediation runbooks, and guardrails for known pitfalls (cluster-scoped queries, uint8 ID mismatches, etc.). Operational introspection and troubleshooting via the materialize-developer server. Examples: “why is my materialized view stale?”, “what can I optimize to save costs?”, “is my source healthy?”
materialize-docs Comprehensive Materialize documentation, including SQL syntax, idiomatic patterns, data ingestion, concepts, and best practices (400+ reference files). Authoring view definitions, learning concepts, looking up patterns. Useful with either MCP server. Examples: “show me how to deduplicate a stream”, “what’s the idiomatic top-K pattern?”, “how do I create a Kafka source?”

Prerequisites

Node.js (v16 or later) must be installed.

Installation

Install the Materialize agent skills with a single command:

npx skills add MaterializeInc/agent-skills

Once installed, you can update installed skills by running npx skills update.

The skills follow the Agent Skills Open Standard and work with any coding agent that supports the standard.

Reduce permission prompts (Claude Code)

Claude Code prompts before reading files outside your project. Since globally installed skills live under ~/.claude/skills/, if you installed the materialize-docs skill globally, Claude Code may ask to approve reads each time the skill opens a new documentation subdirectory.

To stop these prompts, grant read access to the materialize-docs skill in ~/.claude/settings.json:

{
  "permissions": {
    "additionalDirectories": ["~/.claude/skills/materialize-docs"]
  }
}

This grants access to just that one skill’s directory. If you have multiple skills installed and want to cover them all at once, you can broaden the path to ~/.claude/skills, though scoping to a single skill is the safer default.

Claude Code’s auto permission mode also removes the prompts, but applies to all tools rather than just this directory.
