Most enrichment catalogues are a list of lookups. The matching family is different in kind: it turns "IBM", "I.B.M." and "International Business Machines" into one key you can group on, which is the hard part of deduplicating a customer list. The rest — company intel, tax rates, standardization — is breadth around that core, and the x402 route means an agent can use any of it without a key at all.
A Go MCP server that makes Interzoid's catalogue of 58 APIs discoverable and callable from any MCP client. The headline capability is similarity keys: two spellings of the same company or person generate the same key, which is what makes deduplication work without exact matches.
- Matching — similarity keys and match scores for company names, individual names, US and global addresses and products, plus combined keys such as `interzoid_company_match_advanced` for higher-precision deduplication
- Company intelligence — `interzoid_business_info`, `interzoid_competitor_analysis`, `interzoid_buying_signals`, `interzoid_private_company_deal_intel`, industry codes, executives, news, ESG and tech stack
- Identity resolution — `interzoid_official_name` for the legal organization name, and `interzoid_company_verification` for registry details and a verification score
- Contact and identity checks — email trust score, IP profile, phone profile
- Tax and regulatory — `interzoid_sales_use_tax_rates`, `interzoid_customs_duty_rates` by HS code, European VAT, IRS per diem
- Standardization and enhancement — organization, country, city and state normalisation; entity type, gender, name origin, language identification, translation, address parsing
- `interzoid_custom_data`, where you define the output fields you want for a subject domain of your choosing
- Utility calls for weather, exchange rates, ZIP codes and page latency
One of three routes. Hosted: point a Streamable HTTP client at https://mcp.interzoid.com/mcp and pass your key as an Authorization bearer header. Local: download the release binary for your platform, or build from source with Go 1.23+, and set INTERZOID_API_KEY. Or no key at all — calls then return a payment-required response and the agent settles per call in USDC on Base through x402, priced by tier. Free API keys are available from Interzoid.
One command plus a key — claude mcp add --transport http interzoid https://mcp.interzoid.com/mcp --header "Authorization: Bearer your-api-key-here", then supply credentials
