Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Reads files and sends them to the network sdk/cli/neus.mjs:563

      .readdirSync(current, { withFileTypes: true })

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Available tools 12

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

neus

neus_agent_create

Create a Trusted Agent in one call: pick a wallet (generate a new one only when asked, otherwise use the signed-in user wallet), create the agent-identity proof, create the agent-delegation proof, and link the delegation to the identity. On success the agent is ready to mount. Keep the same agentId and agentWallet on retries.

neus_agent_link

Check whether a Trusted Agent has matching identity and permission proofs. Returns linked status or one setup step.

neus_agent_mount

Connect agent context by loading a Trusted Agent’s identity, permissions, skills, and current settings.

neus_context

Start here. Returns the signed-in profile, available verifiers, and the recommended workflow in one call. Handles signed-in and offline modes, no separate profile tool needed.

neus_proofs_check

Check whether existing portable proofs meet the requested requirements. This is read-only and never creates a proof. Omit the wallet when signed in.

neus_proofs_get

Read current portable proof details for a wallet or DID, including titles, tags, status, and content. Omit the wallet when signed in.

neus_secret_create

Store a secret, such as an API key, as an encrypted record. Tools never return the saved value.

neus_secret_list

List saved secret names, types, and update times without exposing their values.

neus_secret_revoke

Revoke a saved secret so it can no longer be used.

neus_verifiers_catalog

Full verifier catalog: supported networks and required inputs. Use this when a check needs schema details beyond the compact verifierSummary in neus_context.

neus_verify

Create or refresh a portable proof after checking that one is needed. Omit the wallet when signed in; the session authorizes the request. Signed-in ownership checks finish here. Share a hosted link only when this tool returns one.

neus_verify_or_guide

Reuse a qualifying portable proof or return the one next step needed to complete the check. Omit the wallet when signed in. Signed-in ownership checks continue with neus_verify. A hosted link is returned only for an outside login, payment, or different account.

NEUS MCP — questions

Answers built from our own checks of this server.

What can NEUS MCP do?

It exposes 12 tools, read directly from the server on our last check. Among them: neus_agent_create, neus_agent_link, neus_agent_mount, neus_context, neus_proofs_check, neus_proofs_get and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is NEUS MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 575 ms. The bar chart above shows every period we have measured.

Did NEUS MCP ever remove tools?

Yes. neus_me is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

Is NEUS MCP still maintained?

The author archived this repository on GitHub, meaning it is no longer maintained. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect NEUS MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to NEUS MCP?

No API key is involved. NEUS MCP answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is NEUS MCP?

It answers our handshake in 575 ms on average, which is faster than 23% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is NEUS MCP open source?

Yes — it is published under the Apache-2.0 licence and 23 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
