Boar blockchain MCP (advanced)
Server Details
Free, keyless MCP server with 50 read-only blockchain tools for Bitcoin, Ethereum, and Mezo. No installation, no API key required -- just add the URL to your MCP client and start querying balances, transactions, blocks, ENS names, ERC-20 tokens, smart contracts, and more. Runs on Cloudflare's global edge network via Streamable HTTP. All tools are strictly read-only and stateless.

Glama MCP Gateway
Connect through Glama MCP Gateway for full control over tool access and complete visibility into every call.
Full call logging
Every tool call is logged with complete inputs and outputs, so you can debug issues and audit what your agents are doing.
Tool access control
Enable or disable individual tools per connector, so you decide what your agents can and cannot do.
Managed credentials
Glama handles OAuth flows, token storage, and automatic rotation, so credentials never expire on your clients.
Usage analytics
See which tools your agents call, how often, and when, so you can understand usage patterns and catch anomalies.
Tool Definition Quality
Average 4.3/5 across 13 of 13 tools scored.
Every tool has a clearly distinct purpose with no ambiguity. The tools are organized into two parallel sets (Ethereum and Mezo) with identical functions, each targeting specific operations like contract calls, data decoding, and batching. Descriptions explicitly differentiate between read-only calls, pure computations, and revert handling, ensuring agents can easily select the correct tool.
Tool names follow a highly consistent verb_noun pattern with a clear prefix (eth_ or mezo_) for network distinction. All tools use snake_case uniformly, and verbs like 'call', 'decode', and 'encode' are applied predictably across both sets, making the naming scheme intuitive and easy to parse.
The 13 tools are well-scoped for an advanced blockchain MCP, covering essential operations for two EVM-compatible networks. Each tool earns its place by providing distinct functionality, such as contract interactions and ABI decoding, without redundancy. The count is appropriate for the domain, enabling comprehensive coverage without being overwhelming.
The tool surface is complete for its stated purpose of advanced blockchain interactions, offering full CRUD-like coverage for read-only operations and data decoding. It includes contract calls, multicall batching, and comprehensive decoding for calldata, logs, returns, and reverts on both Ethereum and Mezo, with no obvious gaps that would hinder agent workflows.

The connector status is unhealthy when Glama is unable to successfully connect to the server. This can happen for several reasons:
The server is experiencing an outage
The URL of the server is wrong
Credentials required to access the server are missing or invalid
