Quality: 61/100 (Good) | Auth: API Key required
FabTally Decode
Developer Tools · Local stdio
Quality: 48/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Claude Task Master if you need specialized Developer Tools tools running via a local process. Choose FabTally Decode if your workspace requires Developer Tools integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Claude Task Master when:
You need dedicated capabilities in the Developer Tools domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (BYOK (Pay Provider Direct)).
You have access to required keys: ANTHROPIC_API_KEY, OPENAI_API_KEY, GOOGLE_API_KEY, PERPLEXITY_API_KEY, XAI_API_KEY, OPENROUTER_API_KEY, MISTRAL_API_KEY, TASK_MASTER_TOOLS.
AI-powered task management system for AI-driven development. Features PRD parsing, task expansion, multi-provider support (Claude, OpenAI, Gemini, Perplexity, xAI), and selective tool loading for optimized context usage.
Decode EVM bytes to JSON: event-log decoder, calldata explainer, selector lookup, ABI fetch.
Flagship.** Decode event LOGS to JSON. `{chain, tx_hash}` decodes every log in a tx, or `{chain, address, topics[], data}` a single log; optional `abi`. Returns event name + canonical signature + named/typed args — handling tuple/array/nested params, anonymous events, indexed vs non-indexed. Resolv…
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Claude Task Master is categorized under Developer Tools and uses a local stdio subprocess. In contrast, FabTally Decode belongs to Developer Tools using local stdio subprocess. Select Claude Task Master when you need capabilities focused on developer tools and FabTally Decode when you require tools for developer tools.
Decode a function call. `{chain, to?, data, abi?}` → selector resolved to a function signature (provided ABI / verified source / 4byte.directory) + fully decoded typed arguments.
selector_lookup
Resolve a 4-byte function selector (`0x`+8 hex) or a 32-byte event topic (`0x`+64 hex) to human signature(s) via 4byte.directory + openchain.xyz, with a verified flag.
abi_fetch
Fetch a contract's verified ABI + metadata (Sourcify/Blockscout) + verification status + full proxy-implementation resolution (EIP-1967/1822/OZ-legacy/beacon) — returns the implementation ABI for proxies. Args: `address`, `chain`.
