Casper Network MCP Server
Enables interaction with the Casper Network blockchain via MCP, providing tools for wallet creation, CSPR transfers, staking/delegation, and account queries.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
create_walletCreates a new Casper Network wallet with ED25519 key pair. Generates public key, account hash, and private key for mainnet use.
transfer_csprTransfer native CSPR tokens to another address on Casper Network mainnet. Creates, signs, and broadcasts the transfer deploy.
get_balanceGet CSPR balance for a wallet address on Casper Network mainnet. Queries the current balance from the blockchain.
get_account_infoGet detailed account information from Casper Network mainnet including associated keys, action thresholds, main purse, and named keys.
delegate_stakeDelegate CSPR tokens to a validator for staking rewards on Casper Network mainnet. Creates, signs, and broadcasts the delegation transaction.
undelegate_stakeUndelegate CSPR tokens from a validator on Casper Network mainnet. Creates, signs, and broadcasts the undelegation transaction. Tokens go through ~14 days unbonding period.
get_staking_rewardsGet staking rewards and delegation information for an account on Casper Network mainnet. Shows total staked amount, validators, and delegation details.
get_validator_infoGet detailed information about a Casper Network validator including stake amounts, delegation rate, delegator count, and performance metrics.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
axios Vulnerable to Full Man-in-the-Middle via Prototype Pollution Gadget in `config.proxy`

CASPER_API_KEYYour API key from cspr.cloud (required)CASPER_NETWORK_NAMENetwork name (default: casper for mainnet)CASPER_PRIVATE_KEYOptional default wallet private key (PEM format)CASPER_PUBLIC_KEYOptional default wallet public keyCASPER_RPC_URLRPC endpoint (default: https://node.cspr.cloud/rpc)PORTTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
8/8 tools missing one or more hints — create_wallet (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); transfer_cspr (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_balance (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +5 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tests exist
No test files found
Add tests that exercise each declared tool.
Secrets never reach shell commands
1 secret value passed to a subprocess as an argument — no shell is invoked, so there is nothing to inject into
Never pass secrets through shell commands. Use library APIs that accept credentials as arguments.
Secrets not logged
13 secret values sent to log/error
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 14 high severity in production deps — @modelcontextprotocol/sdk@1.20.1 (high), @modelcontextprotocol/sdk@1.20.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
