CVE-2022-29244high · fixedCVSS 7.5

Packing does not respect root-level ignore files in workspaces

### Impact `npm pack` ignores root-level `.gitignore` & `.npmignore` file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=<name>`). Anyone who has run `npm pack` or `npm publish` with workspaces, as of [v7.9.0](https://github.com/npm/cli/releases/tag/v7.9.0) & [v7.13.0](https://github.com/npm/cli/releases/tag/v7.13.0) respectively, may be affected and have published files into the npm registry they did not intend to include. ### Patch - Up

CVE-2018-7408high · fixedCVSS 7.8

Incorrect Permission Assignment for Critical Resource in NPM

An issue was discovered in an npm 5.7.0 2018-02-21 pre-release (marked as "next: 5.7.0" and therefore automatically installed by an "npm upgrade -g npm" command, and also announced in the vendor's blog without mention of pre-release status). It might allow local users to bypass intended filesystem access restrictions because ownerships of /etc and /usr directories are being changed unexpectedly, related to a "correctMkdir" issue.

CVE-2013-4116low · fixed

Local Privilege Escalation in npm

Affected versions of `npm` use predictable temporary file names during archive unpacking. If an attacker can create a symbolic link at the location of one of these temporary file names, the attacker can arbitrarily write to any file that the user which owns the `npm` process has permission to write to, potentially resulting in local privilege escalation. ## Recommendation Update to version 1.3.3 or later.

npm CLI exposing sensitive information through logs

Versions of the npm CLI prior to 6.14.6 are vulnerable to an information exposure vulnerability through log files. The CLI supports URLs like `<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>`. The password value is not redacted and is printed to stdout and also to any generated log files.

npm Vulnerable to Global node_modules Binary Overwrite

Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a `serve` binary, any subsequent installs of packages that also create a `serve` binary would overwrite the first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory. This b

README

SQD Portal MCP Server

An MCP server that answers blockchain questions from SQD Portal data: transactions, logs, traces, token transfers, wallets, analytics, time series, and candles across EVM, Solana, Bitcoin, Substrate, Hyperliquid, and Tron networks, with an optional in-host Explorer.

The server does not index chains itself. It validates input, plans bounded Portal queries, and returns results with coverage, freshness, pagination, and evidence metadata so an assistant can say exactly what it saw. No SQD account, API key, or client credential is required.

It speaks the stateless MCP 2026-07-28 protocol over HTTP and stdio and keeps the SDK-managed legacy negotiation path for clients still rolling out that revision. Release notes are in CHANGELOG.md. See CONTRIBUTING.md to work on the code and SECURITY.md to report a vulnerability.

Current public surface

28 public tools
3 advanced/debug tools
public params use network
discovery filters use vm
no legacy tool aliases in v0.8.x

Raw query tools default to compact responses. Ask for response_format: "full" only when you need the larger payload.

Entity questions can use portal_resolve_entity first. It resolves EVM token symbols/addresses, EVM contract aliases, pool identifiers, protocol names, and Hyperliquid coin names into query-ready filters while keeping ambiguous matches explicit.

Token symbol resolution and token metadata come from open token-list data, not baked-in token address constants. Responses include explicit notices when token-list data is unavailable, stale, or unsupported for a network.

Wallet questions should start with portal_get_wallet_summary. It returns fund_flow by default, including inbound/outbound movement, asset flows, counterparties, largest observed movements, and next evidence pivots before raw-tool drill-down.

Tool groups

Discovery:

portal_list_networks
portal_get_network_info
portal_get_head
portal_resolve_entity

Cross-chain convenience:

portal_get_recent_activity
portal_get_wallet_summary
portal_get_time_series

EVM:

portal_evm_query_transactions
portal_evm_query_logs
portal_evm_query_traces
portal_evm_query_token_transfers
portal_evm_get_contract_deployment
portal_evm_get_contract_activity
portal_evm_get_analytics
portal_evm_get_ohlc

Solana:

portal_solana_query_transactions
portal_solana_query_instructions
portal_solana_get_analytics

Bitcoin:

portal_bitcoin_query_transactions
portal_bitcoin_get_analytics

Substrate:

portal_substrate_query_events
portal_substrate_query_calls
portal_substrate_get_analytics

Hyperliquid:

portal_hyperliquid_query_fills
portal_hyperliquid_get_analytics
portal_hyperliquid_get_ohlc

Tron:

portal_tron_query_transactions
portal_tron_query_logs

Advanced/debug:

portal_debug_query_blocks
portal_debug_resolve_time_to_block
portal_debug_hyperliquid_query_replica_commands

These groups are also the toolsets (discovery, convenience, evm, solana, bitcoin, substrate, hyperliquid, tron, debug). A deployment can trim the catalog with MCP_TOOLSETS or MCP_TOOLS, and an HTTP connection can narrow it further with ?toolsets= or an X-MCP-Toolsets header; see the HTTP deployment notes. With nothing configured the full 31-tool surface is served, and the hosted endpoint keeps that default.

Supported data

EVM networks indexed by Portal, including Base, Ethereum, Optimism, Arbitrum, Monad, Hyperliquid EVM, and many others
Tron native transactions (TRX transfers, TRC-10 transfers, contract calls with inline logs and internal transactions) and TVM event logs such as TRC-20 transfers, with Base58 or hex addresses, exact TRX amoun
