概览

AI 生成的概览

Tomba MCP 服务器，通过 Tomba API 提供邮箱查找、验证、电话查询以及联系人与公司信息补全。

可以做什么
  • 查找与验证邮箱：域名搜索、邮箱查找器、作者与 LinkedIn 查找、邮箱数量、来源、格式规律及可投递性验证
  • 补全联系人与公司：个人、公司与组合补全，以及电话号码查找与验证
  • 调研域名与公司：域名状态、自动补全、相似域名、技术栈、员工地区分布及带筛选条件的公司搜索
  • 管理账户：账户与用量信息、数据标记、线索、API 密钥与请求日志
  • 读取 Tomba 资源，并运行联系人挖掘、线索生成与市场调研等预置提示词
适用场景
适合需要查找或验证商务邮箱、查询电话号码、补全潜在客户资料，或为销售、招聘和市场调研了解公司与技术栈的场景。
运行要求
可使用 mcp.tomba.io 托管端点并通过 OAuth 登录，或在本地以 Node.js 18 及以上运行 npm 包。本地及 API 密钥方式需要 Tomba 账户，并设置 TOMBA_API_KEY 与 TOMBA_SECRET_KEY 环境变量，或使用由二者生成的 Authorization bearer 令牌。需要能访问 Tomba API 的网络。
安装前请注意
需要 Tomba API 凭据（TOMBA_API_KEY、TOMBA_SECRET_KEY 或 Authorization bearer 令牌），应避免写入共享配置。调用会消耗套餐额度，并受套餐等级限流。部分工具会写入数据，例如创建线索和提交数据标记。关于个人、邮箱和域名的查询会发送至 Tomba 第三方服务，补全个人联系数据前请考虑隐私与同意问题。

Performance & Reliability

Timeout

All API calls have a 120-second timeout. Tomba searches run in real time against live infrastructure — response times vary with the target company's SMTP server speed, website responsiveness, and the depth of catch-all detection.

Retry with Exponential Backoff

All API calls automatically retry up to 3 times with exponential backoff on:

  • 429 Too Many Requests (rate limit exceeded)
  • 5xx server errors

Retry delays: 1s → 2s → 4s.

Rate Limits

Rate limits are enforced per endpoint and per plan:

PlanPer SecondPer MinutePer Day
Free125
Basic350500
Growth5801,000
Pro81504,000
50,000+ plansUnlimitedUnlimitedUnlimited

No credits are charged when Tomba cannot provide a result. Duplicate requests within 30 days are not counted again.

Transport Options

  • stdio - Standard input/output (default, for Claude Desktop)
  • http - HTTP server with REST endpoints

Installation

Prerequisites

  • Node.js 18 or higher

Note: The npm package has been renamed from tomba-mcp-server to @tomba-io/tomba-mcp-server. Please update your configurations accordingly.

Option 1: Install via NPX (Recommended)

The easiest way to use the Tomba MCP server is via npx, which doesn't require cloning the repository:

macOS/Linux

Add to your claude_desktop_config.json (~/Library/Application Support/Claude/claude_desktop_config.json):

json
{    "mcpServers": {        "tomba": {            "command": "npx",            "args": ["-y", "@tomba-io/tomba-mcp-server"],            "env": {                "TOMBA_API_KEY": "your-api-key-here",                "TOMBA_SECRET_KEY": "your-secret-key-here"            }        }    }}
Windows

Add to your claude_desktop_config.json (%APPDATA%\Claude\claude_desktop_config.json):

json
{    "mcpServers": {        "tomba": {            "command": "npx",            "args": ["-y", "@tomba-io/tomba-mcp-server"],            "env": {                "TOMBA_API_KEY": "your-api-key-here",                "TOMBA_SECRET_KEY": "your-secret-key-here"            }        }    }}

Note: The -y flag automatically accepts the installation prompt, and npx will always fetch the latest version.

Option 2: Install from Source

If you want to modify the server or contribute to development:

bash
# Clone the repositorygit clone https://github.com/tomba-io/tomba-mcp-server.gitcd tomba-mcp-server
# Install dependenciesyarn install
# Build the projectyarn build

Configuration

OpenClaw Skill

This repository includes workspace-local skills in skills/. The Cursor plugin (.cursor-plugin/plugin.json) loads them as well.

skills/tomba-contact-intelligence/SKILL.md is the main skill. It helps the agent pick the right Tomba MCP tools for contact discovery, company research, email verification, phone lookup, and prospect enrichment workflows.

Each MCP tool also has its own skill folder, skills/tomba-<tool-name>/SKILL.md. Each one covers the tool's inputs, workflow, expected output, and an example call:

GroupSkills
Emailtomba-email-finder, tomba-email-verifier, tomba-email-enrichment, tomba-email-count, tomba-email-sources, tomba-email-format
Discoverytomba-domain-search, tomba-author-finder, tomba-linkedin-finder
Phonetomba-phone-finder, tomba-phone-validator
Companytomba-companies-search, tomba-company-enrichment, tomba-similar-finder, tomba-technology-finder, tomba-autocomplete, tomba-location, tomba-domain-status
Enrichmenttomba-person-enrichment, tomba-combined-enrichment
Leadstomba-list-leads, tomba-create-lead
Data qualitytomba-list-flags, tomba-create-flag
Accounttomba-account-info, tomba-usage-info, tomba-list-keys, tomba-get-logs

To use it:

  1. Open this repository as your OpenClaw workspace, or copy the skills/tomba-* directories you need into your OpenClaw skills directory.
  2. Ensure the Tomba MCP server is configured and available to OpenClaw.
  3. Start a new OpenClaw session so the skill is loaded.

Example prompts:

  • "Find the best contact for partnerships at stripe.com and verify the email before you return it."
  • "Research fintech companies in Germany, then identify likely sales contacts for the top matches."
  • "Enrich this prospect with email, phone, company technology, and similar competitors: [email protected]"

Claude Code Plugin

This repository is also a Claude Code plugin marketplace (.claude-plugin/). The plugin bundles every skill in skills/ and connects to the hosted MCP server at https://mcp.tomba.io/mcp:

bash
/plugin marketplace add tomba-io/tomba-mcp-server/plugin install tomba@tomba

Then run /mcp and authenticate the tomba server with OAuth. No API keys are needed. Plugin skills are namespaced, for example /tomba:tomba-domain-search zapier.com.

Codex Plugin

.codex-plugin/plugin.json packages the same skills for OpenAI Codex. It loads the remote server from .mcp.json. After installing the plugin, sign in with OAuth:

bash
codex mcp login tomba

To use API keys instead of OAuth, send the X-Tomba-Key and X-Tomba-Secret headers, or Authorization: Bearer <base64(ta_key:ts_secret)>, to https://mcp.tomba.io/mcp.

Claude Desktop Setup

To use this server with Claude Desktop, add the configuration to your claude_desktop_config.json file.

Using NPX (Recommended)

This method automatically uses the latest published version:

macOS/Linux (~/Library/Application Support/Claude/claude_desktop_config.json):

json
{    "mcpServers": {        "tomba": {            "command": "npx",            "args": ["-y", "@tomba-io/tomba-mcp-server"],            "env": {                "TOMBA_API_KEY": "your-api-key-here",                "TOMBA_SECRET_KEY": "your-secret-key-here"            }        }    }}

Windows (%APPDATA%\Claude\claude_desktop_config.json):

json
{    "mcpServers": {        "tomba": {            "command": "npx",            "args": ["-y", "@tomba-io/tomba-mcp-server"],            "env": {                "TOMBA_API_KEY": "your-api-key-here",                "TOMBA_SECRET_KEY": "your-secret-key-here"            }        }    }}
Using Local Installation

If you've built from source, use the absolute path to your installation:

macOS/Linux:

json
{    "mcpServers": {        "tomba": {            "command": "node",            "args": ["/ABSOLUTE/PATH/TO/tomba-mcp-server/server/index.js"],            "env": {                "TOMBA_API_KEY": "your-api-key-here",                "TOMBA_SECRET_KEY": "your-secret-key-here"            }        }    }}

Windows:

json
{    "mcpServers": {        "tomba": {            "command": "node",            "args": [                "C:\\ABSOLUTE\\PATH\\TO\\tomba-mcp-server\\server\\index.js"            ],            "env": {                "TOMBA_API_KEY": "your-api-key-here",                "TOMBA_SECRET_KEY": "your-secret-key-here"            }        }    }}

Important Notes:

  • Replace your-api-key-here and your-secret-key-here with your actual Tomba API credentials
  • For local installation, replace /ABSOLUTE/PATH/TO/tomba-mcp-server with the full path to your installation directory
  • Restart Claude Desktop after updating the configuration

X-RateLimit-Limit: 1000X-RateLimit-Remaining: 999X-RateLimit-Reset: 1609459200

Learn more about Tomba API Rate Limits.

Handling Rate Limits

When you exceed your rate limit, the API returns a 429 Too Many Requests status with:

json
{    "error": {        "type": "rate_limit",        "message": "Rate limit exceeded. Please try again in 60 seconds",        "code": 429    }}

Best Practices

  1. Monitor Usage: Check your dashboard at tomba.io/dashboard
  2. Implement Backoff: Handle 429 responses with exponential backoff
  3. Batch Operations: Use domain search for multiple emails from the same domain
  4. Cache Results: Store results locally to avoid duplicate requests
  5. Plan Accordingly: Upgrade your plan based on usage patterns

Usage Tips

  • Domain search returns multiple emails per request (more efficient than individual lookups)
  • Email verification consumes credits only for valid email formats
  • Phone finder may return multiple numbers per request
  • Enrichment provides comprehensive data in a single request

Troubleshooting

Server Not Starting in Claude Desktop

  1. Check Node.js version: Ensure you have Node.js 18 or higher

    bash
    node --version

  2. Using NPX:

    • Ensure you have a stable internet connection for the first run
    • The -y flag should auto-accept the installation
    • NPX will cache the package after first use

  3. Using Local Installation:

    • Verify absolute path is correct in your config
    • Ensure server/index.js exists: ls -la server/index.js
    • Make sure you ran yarn build successfully

  4. Verify API credentials: Ensure your Tomba API keys are correct

  5. Check Claude logs:

    • macOS: ~/Library/Logs/Claude/mcp*.log
    • Windows: %APPDATA%\Claude\logs\mcp*.log

NPX-Specific Issues

"npx command not found":

  • Ensure npm is installed: npm --version
  • NPX comes with npm 5.2.0+, update if needed: npm install -g npm

Package not found:

  • Verify the package is published: npm view @tomba-io/tomba-mcp-server
  • Try clearing npm cache: npm cache clean --force

Always downloading package:

  • This is normal behavior with -y flag
  • NPX caches the package after first download
  • For a permanent installation, use local installation method

Authentication Errors

  • Verify your API keys at https://app.tomba.io/dashboard
  • Ensure environment variables are properly set in the config
  • Check that your API subscription is active

Tools Not Responding

  • Check your Tomba API rate limits
  • Verify network connectivity
  • Review server logs for error messages
