What it does

Subtensor MCP is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

7 tools offered to AI assistants

  • subtensor_search · Search across all Subtensor pallets, events, calls, storage, constants, and errors by keyword.
  • subtensor_lookup · Get detailed info about a specific pallet, event, call, storage item, constant, error, SCALE type, RPC method, protocol account, or EVM precompile. Accepts URN identifiers with optional #field.path drilling.
  • subtensor_list · Browse items by category: pallets, events, calls, storage, constants, errors, types, runtime APIs, RPC methods, protocol accounts, EVM precompiles, mechanisms, workflows, hyperparameters, cli_flags, build_features, chain_specs, or env_vars.
  • subtensor_explore · Explore relationships, version history, removed items, changelogs, and migration guides between runtime versions.
  • subtensor_explain · Understand Bittensor concepts, workflows, mechanisms, runtime APIs, runtime errors, extrinsic format, or get code examples.
  • subtensor_preferences · Get or set session preferences for language, node URL, and node type. Language affects field name casing (TypeScript=camelCase, others=snake_case) and code examples.
  • subtensor_decode · Decode SCALE-encoded hex into labelled fields with RAO→TAO and hex→SS58 conversions applied. Omit pallet and name to identify an event or call from its two-byte (pallet index, item index) prefix — the usual case when you have bytes and want

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. $9.99/month.
