Endpoint, auth type and tool list, checked by connecting on 4 November 2026. Source: https://agentmcpdirectory.com/directory/etherscan-io Site: Agent MCP Directory Last reviewed: 2026-11-05 # Etherscan: MCP server, CLI and agent surfaces Yes: Etherscan runs a public MCP server at mcp-keyless.etherscan.io that listed 17 tools to a client with no credentials on 4 November 2026. Examples: get\_native\_balance, get\_transactions, get\_internal\_transactions. It speaks streamable-http, protocol 2025-11-25. Open servers are readable by any agent; writes still depend on each tool. ## Fact sheet | Company | Etherscan | | --- | --- | | Domain | etherscan.io | | Category | Developer Tools (assigned by this directory from the registry description) | | MCP server | Verified (No authentication) | | Tranco rank | 5,489 on the list of 4 November 2026 | | Ora score | none: Ora returned no cached score for etherscan.io when asked on 5 November 2026 | | Company found through | the official MCP Registry | | Last verified | 4 November 2026 | ## MCP server | Endpoint | https://mcp-keyless.etherscan.io/mcp | | --- | --- | | How it was found | listed in the official MCP Registry | | Transport | streamable-http | | HTTP status | 200 | | Protocol version | 2025-11-25 | | Server | etherscan-mcp 2.4.0 | | Capabilities | tools, resources | | Tools | 17 | | Resources | 1 | | Prompts | 0 | | Connected | 4 November 2026, 20:01 UTC | | Handshake time | 1,219 ms over 1 attempt | ### Tools listed 17 tools - get\_native\_balance - get\_transactions - get\_internal\_transactions - get\_token\_transfers - resolve\_ens\_name - get\_contract\_source - get\_contract\_abi - get\_contract\_creation - get\_transaction\_receipt\_status - get\_transaction\_status - get\_gas\_oracle - get\_block\_by\_timestamp - get\_supported\_chains - get\_logs - get\_transaction\_by\_hash - get\_transaction\_receipt - render\_etherscan\_widget ### Connector log 4 connections on 4 November 2026, read-only methods only - 19:56:08Z https://mcp.etherscan.io/mcp sent initialize result auth-required-no-oauth (HTTP 401) 807 ms - 19:56:09Z https://mcp-keyless.etherscan.io/mcp sent initialize, notifications/initialized, tools/list, resources/list result verified (HTTP 200) 875 ms - 20:01:46Z https://mcp.etherscan.io/mcp sent initialize result auth-required-no-oauth (HTTP 401) 1197 ms - 20:01:47Z https://mcp-keyless.etherscan.io/mcp sent initialize, notifications/initialized, tools/list, resources/list result verified (HTTP 200) 1219 ms ## Authentication | Auth type | No authentication | | --- | --- | ### The sign-in route, step by step 1. Send the handshake to `https://mcp-keyless.etherscan.io/mcp` over streamable-http. Servers on the 2026-07-28 revision answer `server/discover`; older servers answer `initialize`. 2. Send `tools/list`, then `resources/list` and `prompts/list` if the capabilities name them. 3. Send no token. The connector sent none and the server answered, so any MCP client can read this list. 4. Calling a tool is a separate step this directory never takes. See [OAuth for MCP: client ID metadata documents and dynamic registration](https://agentmcpdirectory.com/guides/oauth-for-mcp-cimd-dcr/) for how each route works. ## CLI No CLI is on record for Etherscan. The directory checks a package only where a source names one, so this is a floor: a company can ship a command line that no source read for this edition mentions. See [shipping a CLI agents can use](https://agentmcpdirectory.com/guides/ship-a-cli-for-agents/). ## Other agent surfaces | Surface | Result | | --- | --- | | OpenAPI file | The path answered with a web page, not an OpenAPI file. | | WebMCP in the initial HTML | Not detected on the home page by the shared crawl. | | MCP discovery file | The path answered with a web page, not the file.
