## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## Install

### How do I install the Strale MCP server?

Strale is a hosted endpoint at https://api.strale.io/mcp?src=mcp-registry, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (9)

### `strale_ping` (~66 tokens)

Check connection

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_getting_started` (~70 tokens)

Get started with Strale

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_execute` (~247 tokens)

Run a Strale tool

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. Inputs follow the capability's own schema, which strale_search lists; the API is documented at https://strale.dev/docs. 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 (monthly per-IP allowance; see GET /v1/platform/facts, static.free_tier_monthly_limit) — strale_search reports which. Paid capabilities debit from the wallet — check strale_balance first for high-value calls.

Input parameters:

- `inputs` (object, required): Input parameters matching the capability's required fields. Check strale_search results for the expected input_fields.
- `max_price_cents` (number): Maximum price in EUR cents. Default: 200 (€2.00). Execution fails if capability costs more.
- `slug` (string, required): Capability slug from strale_search results, e.g. 'swedish-company-data', 'vat-validate', 'iban-validate'

### `strale_search` (~169 tokens)

Search tools and bundles

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.

Input parameters:

- `category` (string): Filter by category: compliance, validation, data-extraction, developer-tools, web3, security, domain-intel, recruiting, sales, legal, text
- `offset` (number): Number of results to skip (for pagination). Default: 0
- `query` (string, required): Search keyword (matched against name, description, slug)

### `strale_balance` (~65 tokens)

Read wallet 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_methodology` (~26 tokens)

Read testing and source notes

Explains testing modes, source context and transaction retrieval. No API key required.

### `strale_trust_profile` (~98 tokens)

Read current test and availability signals

Reads current public test results for a tool or bundle: badge, tested flag, recent pass rate and last-tested time where available. Use the catalogue for inputs, limitations and sources. No API key required.

Input parameters:

- `slug` (string, required): Capability or solution slug, e.g. 'swedish-company-data' or 'eu-company-due-diligence'
- `type` (string): Whether this is a capability or a bundled solution

### `strale_transaction` (~91 tokens)

Read a transaction record

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.

Input parameters:

- `transaction_id` (string, required): Transaction ID returned from a strale_execute call

### `strale_web3_assurance` (~468 tokens)

Check on-chain counterparty

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, limited evaluator set). Use before any agent transacts on-chain — sending value, swapping, staking, minting, bridging, or interacting with a contract.

Input parameters:

- `action` (string): Optional intended action. When provided, enables pre-trade simulation (outbound mode) and tunes verdict severity.
- `agent_id` (string): Optional ERC-8004 agent identifier for the calling agent.
- `amount_usd` (number): Optional amount in USD. Sharpens verdict for high-value flows.
- `caller_jurisdiction` (string): Optional ISO country code for jurisdiction-aware verdict (US, EU, UK, etc.).
- `chain` (string): Chain. EVM: 'ethereum' (default), 'base', 'polygon', 'arbitrum', 'optimism', 'bsc'. Or 'solana'.
- `mode` (string): Default 'outbound' (agent → recipient, 8s budget, all evidence). Use 'reverse-call' when you are an x402 service publisher gating an inbound buyer (critical evidence only, limited evaluator set).
- `target` (string, required): On-chain target. EVM wallet/contract/token (0x...), Solana address, or DeFi protocol slug (e.g. 'aave', 'uniswap-v3').
- `target_type` (string): Target kind. Inferred when omitted: 0x... → wallet (default), .eth/.sol → wallet, slug → protocol.

## Common questions

### What is the Strale MCP server?

Strale is an MCP server listed in the public MCP registry as io.github.strale-io/strale. Hundreds of pay-per-call tools for agents: company records, screening, validation, web reading. This page covers its hosted endpoint (https://api.strale.io/mcp?src=mcp-registry).

### Is the Strale MCP server safe to use?

Strale scores 69 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Strale MCP server expose?

Strale exposes 9 tools: strale_ping, strale_getting_started, strale_execute, strale_search, strale_balance, and 4 more. Their descriptions and schemas cost roughly 1,300 tokens of context every time the server is loaded.

### Does the Strale MCP server require authentication?

Its publisher declares no required credentials for Strale. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the Strale MCP server still maintained?

Strale is still listed in the MCP registry, though our most recent checks did not reach this channel. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
