Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command .claude/hooks/handoff-stop.mjs:29
const run = spawnSync(process.execPath, args, { cwd: root, encoding: "utf8", timeout: 120_000 });

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 5 min ago.

run in your terminal
claude mcp add strale --transport http https://api.strale.io/mcp

This one needs environment variables set before it will start: STRALE_API_KEY (Your Strale API key (starts with sk_)). The author declared them in the registry entry; get the values from the project itself.

Available tools 9

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

strale
strale_balance
Returns the current Strale wallet balance. Call this before executing paid capabilities to verify sufficient funds, or after a series of calls to reconcile spend. Returns balance in EUR cents (integer) and formatted EUR string. Requires an API key — returns an auth instruction if none is configured.
strale_execute
Executes a Strale capability by slug and returns the result. Use this when you need to perform any verification, validation, lookup, or data extraction from the capability registry. Call strale_search first to find the right slug and required input fields. Returns a result object with the capability output, latency, price charged, and data provenance. Several capabilities are free without an API key (10/day limit) — strale_search reports which. Paid capabilities debit from the wallet — check strale_balance first for high-value calls.
strale_getting_started
Explains how to start using Strale and what is available without credentials. Call this on first connection. Returns the current free-tier capability list with example inputs, the pay-per-call (x402) route that needs no signup, and how to reach the full registry. No API key required.
strale_methodology
Returns Strale's trust methodology as a short reference document — covers test cadence, audit records, and provenance. No API key required.
strale_ping
Checks that the Strale API is reachable and the MCP server is running. Call this before a series of capability executions to verify connectivity, or when troubleshooting connection issues. Returns server status, version, tool count, capability count, solution count, and a timestamp. No API key required.
strale_search
Searches the Strale capability registry by keyword, category, or natural language query. Use this when you need to find the right capability for a task but don't know the exact slug. Returns matching capabilities and solutions ranked by relevance, each with slug, name, description, category, and price in EUR cents. The registry spans company data, compliance, finance, web intelligence, and developer tools. No API key required to search.
strale_transaction
Retrieve a past execution record by transaction ID. Returns inputs, outputs, latency, price, data provenance, success/failure status, and failure categorization. Use this to inspect what a previous strale_execute call returned, debug failures, or provide an audit trail. Free-tier transactions are accessible by ID without an API key.
strale_trust_profile
Returns the trust profile for a capability or solution. Call this before relying on a capability for high-stakes decisions, or when a user asks how reliable a specific check is. Returns lifecycle state, last-tested timestamp, recent test history, known limitations, data source and provenance, and cost envelope. Strale deliberately exposes no single numeric quality score — judge from the test history and limitations. No API key required.
strale_web3_assurance
Returns a decision-ready answer about an on-chain counterparty (wallet, smart contract, token, DeFi protocol, or bridge) in a single call. Surfaces verdict (proceed/review/block/insufficient_evidence), reason_codes (machine-parsable UPPERCASE_SNAKE_CASE), critical_flags, suggested_action, evidence map (sanctions, mixer-graded, scam-cluster, wallet-history, token-safety, contract-verification, protocol-risk, EAS attestations, ERC-8004 reputation, more), and a sidecar audit_url. Two modes: 'outbound' (agent vetting recipient pre-payment, full evaluator set, 8s budget) or 'reverse-call' (service publisher gating an inbound x402 buyer in real-time, critical evaluators only, sub-second SLA). Use before any agent transacts on-chain — sending value, swapping, staking, minting, bridging, or interacting with a contract.

Strale - 290+ API capabilities for AI agents — questions

Answers built from our own checks of this server.

What can Strale - 290+ API capabilities for AI agents do?
It exposes 9 tools, read directly from the server on our last check. Among them: strale_balance, strale_execute, strale_getting_started, strale_methodology, strale_ping, strale_search and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Strale - 290+ API capabilities for AI agents working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 522 ms. The bar chart above shows every period we have measured.
How do I connect Strale - 290+ API capabilities for AI agents?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Strale - 290+ API capabilities for AI agents need an API key?
No. Strale - 290+ API capabilities for AI agents completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Strale - 290+ API capabilities for AI agents?
It answers our handshake in 522 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Strale - 290+ API capabilities for AI agents?
The npm package strale-mcp was installed 61 times in the last week. Week over week that is -38%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Strale - 290+ API capabilities for AI agents open source?
Yes — it is published under the MIT licence, written in TypeScript, 5 stars on GitHub and 25 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
