Blockscout Agent Skills

A collection of AI agent skills for working with the Blockscout ecosystem — blockchain explorers, APIs, and supporting services.

Each skill is a self-contained directory of structured instructions and helper scripts that give an AI agent domain expertise in a specific area. Skills follow the markdown-based format compatible with Claude Code, Codex, Cursor, OpenClaw, Claude Cowork, and other agents that support skill/instruction loading.

Skills

Skill	Description
blockscout-analysis	Modular skill for blockchain data analysis and scripting using the Blockscout MCP Server. Guides agents to use native tools, REST API scripts, or hybrid flows for multi-chain EVM data.
web3-dev	Build web3 applications, scripts, CLIs, bots, and mobile/desktop clients that read blockchain data via the Blockscout PRO API — a single HTTP API spanning 100+ EVM chains. Sibling to blockscout-analysis (which targets the MCP server).

Prerequisites

Different skills depend on different Blockscout backends. Pick the row that matches the skill you want to install:

Skill	Requires
blockscout-analysis	Blockscout MCP server (auto-configured by the Claude Code and Codex plugins; configured manually for other agents — see below)
web3-dev	Blockscout PRO API key (no MCP server involved)

Setup

Each skill is a directory with a SKILL.md entry point and supporting docs/scripts. Integration depends on your agent platform — see examples below. In the snippets below, replace <skill> with the directory name of the skill you want to install (e.g. blockscout-analysis, web3-dev).

Skills CLI (40+ agents)

One command installs a skill to 40+ coding agents (Claude Code, Codex, Cursor, Cline, Copilot, Windsurf, Continue, and more):

npx skills@latest add https://github.com/blockscout/agent-skills --skill <skill>

Use -g to install globally, or -a <agent> to target a specific agent. See skills.sh/docs for the full list of supported agents and options.

Note: The Skills CLI installs the skill instructions only. Skill-specific backends (MCP server for blockscout-analysis, PRO API key for web3-dev) are not configured automatically — see Prerequisites.

Claude Code

For blockscout-analysis, no separate MCP server configuration is needed — it is set up automatically as part of the plugin installation. For web3-dev, you still need to provide a PRO API key (see Prerequisites).

claude plugin marketplace add blockscout/agent-skills
claude plugin install <plugin>@blockscout-ai

Replace <plugin> with blockscout-analysis or web3-dev (or run the install command once per plugin).

Claude Desktop (Chat / Cowork / Code)

Must be configured separately for Chat/Cowork and for Code by the same procedure.

1. Choose Customize in the sidebar:

   

2. Choose Browse plugins → Personal → Add marketplace from GitHub:

   

3. Enter the GitHub repo ID blockscout/agent-skills and press Sync:

   

4. The marketplace blockscout-ai will appear in the list of Personal plugins. Click Install on each skill plugin you want (blockscout-analysis, web3-dev):

   

5. Once installed, the plugin details are available in the Customize window:

   

6. If the plugin has MCP servers associated (e.g. blockscout-analysis), their info will be available in the Connectors sub-item:

   

Codex CLI / Codex App

Add the marketplace first, then enable the skill plugin from inside Codex via the /plugin slash command (the command opens an interactive picker). For blockscout-analysis, the Blockscout MCP server is auto-configured by the plugin — no manual MCP setup required. For web3-dev, provide a PRO API key (see Prerequisites).

codex plugin marketplace add blockscout/agent-skills

Then run codex and type:

/plugin

Select the marketplace blockscout-ai and enable the plugin(s) you want (blockscout-analysis, web3-dev).`

Gemini CLI

The first command (registering the Blockscout MCP server) is only needed for blockscout-analysis; skip it for web3-dev.

gemini mcp add --transport http blockscout https://mcp.blockscout.com/mcp   # blockscout-analysis only
gemini skills install https://github.com/blockscout/agent-skills --path <skill>
