Cursor uses the same mcpServers schema as Claude Desktop. Project config wins over global.

Continue uses an array of server objects rather than a map.

Add to context_servers. Zed hot-reloads on save.

One-liner. Verify with claude mcp list. Remove with claude mcp remove.

Use Cases

Real-world ways to use skills

How to scaffold an Anchor program with Claude

👤 Solana developers starting a new on-chain program ⏱ ~60 min advanced

When to use: You need a new Anchor program and don't want to pattern-match from random GitHub repos.

Prerequisites

Rust + Anchor CLI installed — rustup + cargo install --git https://github.com/coral-xyz/anchor anchor-cli
Skill cloned — git clone https://github.com/sendaifun/skills ~/.claude/skills/skills-sendai

Flow

State the program goal

Scaffold an Anchor program for a simple escrow: deposit SOL, release to seller on confirmation.✓ Copied

→ Program with accounts, instructions, and idiomatic Anchor attributes
Tests

Add TypeScript client tests using the Anchor test harness.✓ Copied

→ tests/ directory with typed client
Build and deploy to localnet

Build, deploy to localnet, and verify the escrow flow with a test transaction.✓ Copied

→ Successful local deploy

Outcome: A working Anchor program with tests.

Pitfalls

Missing account constraints — Insist on explicit constraints for every account; skill prompts Claude to enumerate them

Combine with: filesystem

Mint and distribute an SPL token

👤 Builders launching a token for a dev/test use case ⏱ ~30 min intermediate

When to use: You need an SPL token script you actually trust.

Flow

Draft the mint script

Write a TypeScript script that creates an SPL token with 9 decimals and mints 1M to a treasury account.✓ Copied

→ Script using @solana/spl-token with proper PDAs
Airdrop helper

Add a function that airdrops to an array of recipients using associated token accounts.✓ Copied

→ ATA creation + transfer

Outcome: A reusable mint + distribute script.

Pitfalls

Forgetting ATA creation — Use getOrCreateAssociatedTokenAccount, not manual derivations

Combinations

Pair with other MCPs for X10 leverage

skills-skill-5 + filesystem

Work across an Anchor monorepo

Read programs/, add a new program following the existing structure.✓ Copied

skills-skill-5 + github

Open PRs for contract changes with meaningful descriptions

Open a PR titled 'feat: escrow program' with tests.✓ Copied

Tools

What this MCP exposes

Tool	Inputs	When to call
anchor-scaffolding	program intent	New program
spl-token-recipes	mint/transfer/airdrop intent	Token work
transaction-builder	list of instructions	Complex multi-ix flows

Cost & Limits

What this costs to run

API quota: none beyond RPC usage you configure
Tokens per call: 5–15k per scaffold
Monetary: free at skill level; Solana fees are your own
Tip: Develop on localnet/devnet; don't burn mainnet SOL for iteration

Security

Permissions, secrets, blast radius

Credential storage: never paste private keys into the prompt — use env vars and ephemeral devnet keys

Data egress: your configured RPC only

Never grant: wallet signing from within a prompt

On-chain code is bearer-asset code: treat security review as mandatory before mainnet
Never ask the skill to work with a mainnet wallet that holds real value

Troubleshooting

Common errors and fixes

anchor build fails

Check Rust toolchain and Anchor CLI version; pin with rust-toolchain.toml.

Verify: anchor --version && rustc --version

Account constraint errors at runtime

Re-ask Claude to enumerate constraints and PDAs explicitly
