Alchemy MCP with Claude: Query Ethereum Data and Automate On-Chain Workflows
The short answer
Claude works with Alchemy through the Model Context Protocol, an open standard that lets Claude securely use software on your behalf. Using Alchemy's MCP server or direct API key access, Claude can fetch blockchain data, query smart contracts and monitor on-chain analytics. Your team sets the permissions and approves any transaction before it is sent.
What is Alchemy?
Alchemy is a blockchain development platform. It provides APIs and developer tools that help teams build and scale applications on Ethereum, the public blockchain network. Developers, engineering teams, product managers and Web3 start-ups use it to read blockchain data reliably, run applications at volume and avoid building their own node infrastructure. It is typically used by teams building decentralised finance, digital asset and NFT products.
How Claude connects to Alchemy through MCP
The Model Context Protocol, or MCP, is an open standard that acts like a universal adapter between Claude and other software. It lets Claude read information from a tool and take actions in it, using access that your organisation controls. Once connected, your team can ask questions in ordinary language rather than writing queries by hand.
Connected to Alchemy, Claude can typically read blockchain data such as wallet balances, transaction histories and token transfers. It can query smart contracts to check their state, and it can help monitor on-chain activity so unusual movements are flagged. For example, a product lead could ask for the number of token transfers from a contract over the past week and receive a clear answer.
Permissions and approvals keep people in charge. Access is granted with your Alchemy API key and limited to what the task needs. Consequential actions, such as sending an Ethereum transaction, can require a named person to review and approve them first. Every action can be recorded in an audit log so your team can see who asked for what and when.
What you can automate
Wallet and token activity checks
Operations staff can ask Claude for the current balance of a wallet, or a list of recent token transfers for a given address. Claude retrieves the data through Alchemy and presents it in a clear summary. This saves analysts from building and maintaining separate scripts for routine checks and helps them respond faster to customer questions.
Smart contract state queries
Developers and product teams often need to confirm what a deployed contract is doing. Claude can query contract state through Alchemy and explain the results in plain English. A product manager can check whether a sale has ended or how many items remain without waiting for an engineer to run the query.
On-chain analytics monitoring
Growth and risk teams can set Claude to review on-chain activity on a regular schedule. It can summarise transaction volumes, highlight unusual spikes and send the summary to the relevant channel. This gives non-technical leaders a regular view of activity without requiring them to read raw blockchain data.
Customer support for Web3 products
Support agents handling questions about transactions can ask Claude to look up the status of a specific transaction hash. Claude retrieves the status from Alchemy and drafts a reply the agent can check before sending. This reduces time spent searching block explorers and improves the consistency of answers given to customers.
Controlled transaction sending
Where a business needs to send Ethereum transactions, such as paying out rewards, Claude can prepare the transaction through Alchemy. A named approver reviews the details, including the recipient and amount, and only then is it sent. The approval step and audit trail help keep these payments under proper control.
An end-to-end workflow: Daily on-chain reporting for a token product
TriggerEvery weekday at 08:00 the scheduled workflow starts.
Claude queries Alchemy for overnight token transfers and contract events for the product.
Claude compares volumes with the previous day and the trailing seven-day average.
Claude flags any unusual spikes or failed transactions for review.
Claude drafts a short summary and posts it to the operations channel in Microsoft Teams.
If a figure needs to be recorded, Claude adds a row to the reporting sheet in Microsoft 365 for the finance team to review.
OutcomeLeaders receive a consistent daily view of on-chain activity by mid-morning. Issues are spotted sooner, and the finance team has a clean record to reconcile against.
How we set it up
Free automation audit
We review your current blockchain workflows with your operations and engineering leads. We identify the tasks where Claude can save time and where human approval is needed.
Secure connection with an API key
We connect Claude to Alchemy using your API key, stored in a managed secrets vault. Access is limited to the networks and capabilities your workflows require.
Workflow design across your systems
We design the end-to-end process, linking Alchemy with Microsoft 365, your CRM or ticketing tool where relevant. We define which actions need named approval.
Testing and monitoring
We test the workflows against real past cases, check the results with your team and set up monitoring and audit logs before anything goes live.
Launch and team training
We launch the workflows and train your staff to use them confidently. We agree on a review schedule so the setup stays accurate as your products change.
Who benefits
- Web3 product managers
- Check contract status and product activity without waiting for engineering support.
- Operations and support leads
- Answer transaction questions faster with consistent, checked responses.
- Finance and risk teams
- Receive regular, summarised on-chain reports with flagged anomalies.
- CTOs and engineering heads
- Reduce repetitive query work and keep sensitive actions behind approval steps.
Security and control
- Access uses your own Alchemy API key, restricted to the capabilities each workflow needs.
- Transactions that move value require a named person to review and approve them first.
- Every action is recorded in an audit log that your team can inspect at any time.
- Test environments are used before any workflow touches live networks or real funds.
- Credentials are stored in a managed secrets vault and rotated on your schedule.
For teams in the US, UK, India and the Middle East
Organisations in the United States, the United Kingdom, India and the Middle East each have different data protection rules. These include the Digital Personal Data Protection Act, 2023 in India and data protection laws in the UAE and Saudi Arabia. We choose the hosting region for your Claude deployment, in India, the United States, the United Kingdom or the European Union, to match your legal and contractual requirements. Blockchain data is public, but any customer or staff data linked to it must still be handled under the rules that apply to you.

Frequently asked questions
What does the Alchemy MCP server do?
The Alchemy MCP server acts as a secure bridge between Claude and Alchemy's blockchain services. It lets Claude read blockchain data, query smart contracts and, where permitted, prepare transactions, all through natural language requests. Your organisation controls which capabilities are switched on.
Is connecting Claude to Alchemy secure?
Security depends on how the connection is set up. Access uses your Alchemy API key, which we store in a managed secrets vault and limit to the tasks you approve. Transactions that move value can require named human approval, and all activity is logged for review.
What can Claude actually do with Alchemy?
Typically, Claude can fetch wallet balances and transaction histories, query smart contract state, monitor on-chain activity and summarise the results. It can also prepare Ethereum transactions for approval. The exact capabilities depend on the permissions you grant during setup.
How long does setup take?
Many organisations complete a first workflow within a few weeks, though timing depends on how many workflows you need and how many systems they connect to. The free automation audit gives you a clearer estimate before any work begins.
What access or plan do I need?
You will need an Alchemy account and an API key with the permissions your workflows require. The specific plan that suits your usage is a question for your Alchemy account and your engineering team. We help you confirm the access level during the audit so you pay only for what you need.
