How do I install the Thegraph skill?

Run npx skillmds@latest add hairyf/thegraph in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Thegraph safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: makes network calls. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Thegraph?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Thegraph free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

The Graph indexes blockchain data into queryable subgraphs. Subgraphs are defined by a manifest (subgraph.yaml), a GraphQL schema, and AssemblyScript mappings; they are queried via GraphQL. Substreams provide parallel, multi-chain indexing with multiple sinks.
