Description
Pay-as-you-go Mobula API access — fetch crypto prices, wallet positions, and market data using a Tempo wallet that pays per call (~$0.0004) in USDC.e. No sub...
Usage Guidance
This skill appears to do what it claims: it creates encrypted hot wallets and automatically signs on-chain USDC.e payments to satisfy Mobula's 402 payment challenges. Before installing, consider: 1) Hot-wallet risk — private keys live on disk (encrypted) and in memory briefly for signing; keep balances small (the skill is designed for a few dollars). 2) File locations created: ~/.mpp-skill/{wallet,json,.secret} and <cwd>/.claude/claudeclaw/wallets/{userId}.json + wallet.secret — ensure these paths are acceptable and protected. 3) Autonomous invocation + payment: the agent can make calls that cause on-chain transfers; the code enforces a $0.01 per-call cap but an attacker on a compromised host or a misconfigured Mobula server could still cause repeated small charges — run in an isolated environment if possible. 4) Supply-chain: the skill depends on the 'viem' library and is installed via bun; verify the upstream GitHub repository/author and consider pinning or auditing dependencies. 5) Multi-tenant note: per-user wallets are tied to process.cwd() for the .claude secret — verify this behavior if you run multiple agents on one host. If these tradeoffs are acceptable (and you keep low balances and verify the repo/deps), the skill is coherent with its stated purpose.
Capability Analysis
Type: OpenClaw Skill
Name: mpp-mobula
Version: 1.0.7
The mpp-mobula skill implements a legitimate pay-per-call interface for the Mobula API using the Machine Payments Protocol (MPP) on the Tempo blockchain. It manages local hot wallets with AES-256-GCM encryption at rest, enforces strict file permissions (chmod 600), and includes a critical safety cap ($0.01) in `src/mpp/tempo-client.ts` to prevent wallet draining from malicious or misconfigured payment challenges. The code is transparent, well-documented (including a detailed `SECURITY.md`), and its network and filesystem permissions are strictly aligned with its stated purpose of facilitating micro-payments for data access.

Capability Assessment
Purpose & Capability
Name/description (Mobula MPP pay-per-call) match the included code: wallet management, tempo-client that handles 402 challenges, and CLI/agent helpers. Declared filesystem and network permissions align with storing encrypted wallets and talking to mpp.mobula.io, rpc.tempo.xyz and relay.link.
Instruction Scope
SKILL.md instructs cloning, running Bun, creating a wallet, funding it via the public bridge, and making paid calls. The instructions only reference the wallet files and the Mobula/Tempo endpoints; they do not ask the agent to read unrelated host files or exfiltrate environment variables.
Install Mechanism
No install spec beyond 'bun install' and a git clone (package.json points to a GitHub repo). The dependency 'viem' is pulled from the package registry — expected for Ethereum/Tempo interactions but note this is third-party code (moderate supply-chain risk compared with no install). There are no downloads from ad-hoc URLs or archive extraction from unknown servers.
Credentials
The skill requires no external credentials or env vars. It creates and stores encryption secrets and wallet files locally (paths: ~/.mpp-skill/* and .claude/claudeclaw/*) which is proportional to a hot-wallet client. No unrelated tokens/keys are requested.
Persistence & Privilege
always:false and user-invocable: true. The skill writes encrypted wallet files and a secret to disk (hot-wallet persistence), which is necessary for operation but is sensitive. The agent can invoke the skill autonomously (platform default) and that will sign and broadcast small payments up to the built-in cap ($0.01 per challenge).
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install mpp-mobula - After installation, invoke the skill by name or use
/mpp-mobula - Provide required inputs per the skill's parameter spec and get structured output
