Common questions

Is NexaLayer safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: NEXALAYER_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 11 days ago, and the latest version (0.2.0) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

NexaLayer MCP Server

This directory contains the MCP server package and implementation. For the repository overview, installation options, complete 16-tool catalog, and backend relationship, see the root README.

Connect an MCP client to NexaLayer products, sessions, health, usage, and spend controls.

"mcpServers": { "nexalayer": { "command": "npx", "args": ["-y", "@nexalayer/mcp"], "env": { "NEXALAYER_API_KEY": "agk_your_key" } } } }

The server writes protocol messages only to stdout. API errors go through MCP tool results. Tool annotations mark reads, paid writes, policy changes, and destructive cleanup so compatible clients can apply approval policies.

Tools

Read: products and exact prices, session detail, health, usage, budget, alerts, balance, and transactions.
Paid write: create or rotate a Session. Use a unique idempotency_key and owner approval.
Policy write: change API-Key and daily budget limits. Require owner approval.
Cleanup: terminate a Session when the task ends. Early termination does not imply a refund. If the upstream is down, billing stops at the first terminate attempt and NexaLayer retries the release in the background.
Support (no charge): nexalayer_check_status, nexalayer_known_issues, nexalayer_report_issue, and nexalayer_get_ticket.

nexalayer_list_products returns a compact, cursor-paginated catalog. It defaults to 20 currently available products, supports type, country, in_stock, limit, and cursor, and excludes internal pricing and supplier fields.

nexalayer_create_session incurs charges against the account balance. Read the current quote and budget, then obtain owner approval before calling it. POST /sessions does not honor include_credentials and omits proxy credentials. PRICE_MISMATCH (409): re-read prices, retry once. BUDGET_EXCEEDED and INSUFFICIENT_BALANCE (402): ask the owner, don't retry.

nexalayer_get_session and nexalayer_rotate_session accept optional include_credentials (default false) and pass it to the API. Credentials are omitted unless include_credentials=true; never log them.

Always read nexalayer_list_products before purchase because it returns the current openAgent-backed quote and availability. Exclusive static proxy sessions are $1.43–$5.86/month (launch pricing, live API authoritative).

nexalayer_list_products → nexalayer_get_budget → owner approval

→ nexalayer_create_session → nexalayer_get_session → health/usage → nexalayer_terminate_session

Common API error codes include AUTH_INVALID_KEY, INSUFFICIENT_BALANCE, BUDGET_EXCEEDED, PRICE_MISMATCH, IDEMPOTENCY_CONFLICT, and RATE_LIMIT_EXCEEDED.

PRICE_MISMATCH is HTTP 409: re-read prices, retry once. BUDGET_EXCEEDED and INSUFFICIENT_BALANCE are HTTP 402: ask the owner, don't retry.

Errors and support

Failed API calls return an MCP tool error (isError: true) with a one-line summary and the full NexaLayer error object in structuredContent.error: code, retryable, retry_after, suggested_action, side_effects, doc_url, known_issue_id, and request_id. Branch on those fields, not on the message text.

When an error is not self-explanatory:

follow error.suggested_action → nexalayer_check_status → nexalayer_known_issues(error_code)

→ nexalayer_report_issue → poll nexalayer_get_ticket after next_check_after_seconds

The server keeps the last 20 request ids and error codes it saw and attaches them to nexalayer_report_issue automatically, along with the MCP client name and package version. Never put API keys, proxy passwords, or full_url in a ticket. Response targets are early-access targets, not guarantees: S1 4h, S2 24h, S3 3 business days, S4 best effort. Human contact: support@nexalayer.net (Telegram @LEWISMIN).

Docker

Build the stdio MCP server from the repository root:

docker build -t nexalayer-mcp ./mcp

The container can start and expose its tool catalog without credentials, which allows MCP directories and clients to inspect it safely:

docker run -i --rm nexalayer-mcp

Pass the API Key only at runtime when calling NexaLayer tools:

docker run -i --rm \

-e NEXALAYER_API_KEY="$NEXALAYER_API_KEY" \ nexalayer-mcp

NEXALAYER_BASE_URL remains optional. The image uses stdio and does not expose a network port or contain credentials.

Request an API key and one-time trial credit at https://nexalayer.net/agents?source=mcp-readme.
