README (SKILL.md)
Cardano Wallet Balances
Query wallet balances, addresses, and UTxOs on the Cardano blockchain.
Prerequisites
@indigoprotocol/cardano-mcpserver running
MCP Tools
get_balances— Retrieve all balances and native assets for the connected walletget_addresses— Retrieve all Cardano addresses for the connected walletget_utxos— Retrieve all UTxOs for the connected wallet
When to use
Use this skill when the user asks about:
- Wallet balances or ADA amount
- Native tokens or assets in their wallet
- Wallet addresses
- UTxO details or UTXO inspection
Data interpretation
- Balances are returned in lovelace (1 ADA = 1,000,000 lovelace). Always convert to ADA for display.
- Native assets are identified by
policyId+nameHex. - The
namefield provides a human-readable label when available.
Usage Guidance
Do not provide your wallet seed phrase unless you fully trust the skill and its publisher. Ask the maintainer why a SEED_PHRASE is required instead of a watch-only address or xpub. Before installing: (1) verify the npm package @indigoprotocol/cardano-mcp on the registry and inspect its repository/source and maintainer history, (2) prefer providing only public addresses or watch-only credentials when possible, (3) if you must test, use an empty/spare wallet with no funds, and (4) avoid storing your real seed phrase in environment variables for third-party skills.
Capability Analysis
Type: OpenClaw Skill
Name: cardano-balances
Version: 1.0.0
The skill bundle is designed to query Cardano blockchain balances and UTxOs using the @indigoprotocol/cardano-mcp package. While it requires a sensitive SEED_PHRASE environment variable to derive wallet information, the code and instructions in SKILL.md and sub-skills/check-balances.md are consistent with the stated purpose and show no signs of data exfiltration, malicious execution, or prompt injection.
Capability Assessment
Purpose & Capability
The skill's functionality (getting balances, addresses, UTxOs) generally aligns with its name and description and the referenced MCP tools. However, requiring a SEED_PHRASE is stronger than normally necessary for read-only balance queries (which can often be done from public addresses or xpub/watch-only data). The SKILL.md does not justify why a full seed phrase is required.
Instruction Scope
The runtime instructions reference only the MCP tools (get_balances, get_addresses, get_utxos) and conversion/display guidance, which is within scope. But SKILL.md does not say how the declared SEED_PHRASE env var is used, stored, or protected. The allowed-tools list (Read, Glob, Grep) could let the skill read local files, yet the instructions never limit or explain use of local data. This ambiguity increases risk because a seed phrase could be accessed/exfiltrated without being explicitly described.
Install Mechanism
Install is a node package: @indigoprotocol/cardano-mcp (npm). Installing an npm package is a common approach for Cardano tooling and is not unusual, but it is a moderate-risk install mechanism because it will place code on disk and execute from the registry. No homepage, repository link, or package version is provided in the metadata, making provenance harder to verify.
Credentials
The skill requires a single env var: SEED_PHRASE. A seed phrase is extremely sensitive (full wallet control). The skill does not request more unrelated credentials, but it also does not explain why the seed phrase is necessary versus less-privileged alternatives (e.g., public addresses, xpub, watch-only keys). Requiring a seed phrase for a read-only balances query is disproportionate unless the skill needs to derive private addresses not otherwise available — this should be explicitly stated and justified.
Persistence & Privilege
The skill is not always-enabled, does not request system-wide config changes, and does not claim to modify other skills or agent settings. Autonomous invocation is allowed (the platform default) but is not combined with other high privileges here.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install cardano-balances - After installation, invoke the skill by name or use
/cardano-balances - Provide required inputs per the skill's parameter spec and get structured output
