How to Connect Lusha to Claude via MCP

💡 No install? Use cloud.anythingmcp.com directly. Sign in, click Connectors → Lusha, paste your credentials, mint an MCP API key and you're done. No Docker, no git clone, no local server.

Lusha + Claude

Give your AI Lusha B2B data: find contacts and companies by name, email, LinkedIn URL or domain, prospect by job title, seniority, industry, size and location, check your credits, and reveal emails, phone numbers and firmographics only for the records you pick. Also reads job change and company signals.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

LUSHA_API_KEY

Step 1 — Get credentials

1. Sign in to Lusha with an account that has API access. Only account admins and managers with API access see the API page.
2. Open API → Manage API Keys at https://dashboard.lusha.com/api/manage-api-keys and create or copy a key.
3. Paste it into LUSHA_API_KEY and install the connector. The key is sent as the api_key header and only to Lusha.
4. Check the setup with lusha_get_account_usage: it shows the credits left and the price of each action, and uses no credits.

Calls that return records cost credits, so the AI asks first: Lusha API v3 charges your account's credit pool for every call that returns data, searches included. Prices depend on your plan, and lusha_get_account_usage lists them per action (search, company reveal, email, phone and so on).

• Free: lusha_get_account_usage (at most 5 calls a minute), lusha_list_filters, lusha_get_filter_values, lusha_list_signal_types, and polling an enrichment job with lusha_get_enrich_job.
• A small charge per result found (nothing when not found): lusha_search_contacts, lusha_search_companies, lusha_prospect_contacts and lusha_prospect_companies. They return previews without emails or phone numbers, plus what an enrichment would reveal and what it would cost.
• More credits: lusha_enrich_contacts (per revealed email and per revealed phone; a phone usually costs several times an email), lusha_enrich_companies (per company), and lusha_get_contact_signals and lusha_get_company_signals (per matched signal).

Before any call that costs credits the AI tells you what it will run, for how many records and what it can cost, and waits for your yes. It keeps result pages small and reveals only the fields you need: emails alone cost less than emails and phones.

How it works: for people and companies you already know, the AI searches by Lusha id, LinkedIn URL, email, name plus company, or company name and domain. For new prospects it first reads the valid filter values (seniority, departments, industries, company sizes, revenue, locations, technologies) and then prospects with include and exclude filters. After you pick records it enriches them by Lusha id, up to 100 at a time. When Lusha answers with a job for data that arrives later, the AI waits and reads the job for free.

Signals: job changes and promotions of contacts, and hiring surges, headcount changes, website traffic, IT spend, news and intent changes at companies. lusha_list_signal_types lists them for free; reading signals costs credits per match.

Personal data, B2B use only: contact records describe real people: names, job titles, employers, work and private email addresses, mobile and direct phone numbers. Use them only for a legitimate business purpose you can justify, such as B2B sales or recruiting under legitimate interest, in line with the GDPR, CAN-SPAM and Lusha's terms. Keep only what you need, respect the do-not-call flag on phone numbers and the EU contact flag, and do not build mass mailing lists or look up private individuals. Lusha itself withholds some people for legal reasons (HTTP 451 or COMPLIANCE_RESTRICTED). The connector gives the AI the same rules.

Rate limits: 25 requests a second per account by default, plus hourly and daily quotas by plan. A 429 means waiting and trying again.

Common errors: 401: the key is wrong, revoked or missing. 402: no credits left. 403: the account is inactive or the plan lacks a feature. 400: an invalid filter value or parameter, named in the answer. 451: Lusha cannot return this person for legal reasons. A successful answer can still mark single records as not found, restricted or failed.

The connector never changes data in Lusha. It does not search and enrich in one call (that would skip your confirmation), and it does not cover lookalikes, buying groups, scoring, website visitors, CRM export, webhooks or the legacy v2 endpoints.

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Claude

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

Recommended path: works on claude.ai web without editing any config file.

1. In Claude, open Customize → Connectors.
2. Click +, then Add custom connector.
3. Enter a name, e.g. Lusha, and the remote MCP server URL https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID, then click Add.
4. Click Connect and sign in to AnythingMCP (OAuth) to allow access.
