What is iota-agent-mcp?

An MCP server that connects AI coding agents to the IOTA blockchain, a network for digital transactions and smart contracts. It supports IOTA wallet operations, Move contract development, and blockchain data queries with human approval for state-changing actions.

Use it to query IOTA data, build and test Move packages, create publish transactions, and approve or reject wallet operations.

It lets an agent work with IOTA without allowing wallet-changing actions to proceed without a person's approval.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00078	$0.01148
Opus 5.5	$0.00031	$0.00459
Sonnet 5	$0.00016	$0.00230
Haiku 4.5	$0.00008	$0.00115

Security

Grade B, and why

iota-agent-mcp scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (jest.config.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

IOTA Agent MCP

MCP server that connects AI coding agents to the IOTA blockchain. Provides 18 tools across wallet operations, Move smart contract development, and on-chain data queries — all via stdio transport with no secrets in the MCP process.

Workflow

Configure the MCP server in your agent's settings (Claude Code, Cursor, VS Code Copilot)
Query on-chain data — fetch objects, transactions, coins, epoch info, or decompile modules
Develop Move contracts — build, test with coverage, generate unsigned publish transactions
Sign and publish — generate unsigned transaction, submit via iota_wallet_sign_execute, check iota_wallet_pending for approval status, verify on-chain with iota_transaction

Signing flow (human-in-the-loop)

Wallet operations that modify state require human approval:

Call iota_wallet_sign_execute with base64-encoded transaction bytes — creates a pending request
Call iota_wallet_pending to confirm the request was queued
The human approves (iota_wallet_approve) or rejects (iota_wallet_reject) via the agent-wallet server
On approval, verify the transaction landed on-chain: call iota_transaction with the returned digest
If rejected, inform the user and do not retry without explicit instruction

Tools

Wallet (8 tools)

iota_wallet_address — Get the active wallet address
iota_wallet_balance — Check IOTA balance for the active wallet
iota_wallet_accounts — List all derived wallet accounts
iota_wallet_sign_execute — Sign and execute a transaction (requires human approval via agent-wallet server)
iota_wallet_pending — List pending signing requests awaiting approval
iota_wallet_approve — Approve a pending signing request by ID
iota_wallet_reject — Reject a pending signing request by ID
iota_wallet_switch_network — Switch between mainnet, testnet, and devnet

Move CLI (4 tools)

iota_cli — Run any IOTA CLI command (e.g. client gas, move new my_project)
iota_move_build — Compile a Move package and report build results
iota_move_test_coverage — Run Move tests with coverage analysis and summary
iota_move_publish_unsigned — Generate unsigned publish transaction for agent-wallet signing

What ships with it

9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
