Argus MCP server

Which MCP servers are Argus's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry nametown.argus/argusverified in the MCP registry

The registry name sits under argus.town. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

  • Server calls itselfargus

  • Protocol version2025-06-18

On 2026-10-28 the server answered initialize and tools/list without a sign-in. First answer in 226 ms.

Should an agent connect itNot proven either way yet
  • Whether its tools do the product's job has not been judged yet.

Once connected

  • For "track provider balances and days of runway in one place", the likely first call is get_overview.
  • create_connect_link change data without a sign-in: anyone with the address can call them.
  • Parameters are untyped or undescribed in 6 of 12 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

  • not sure · catch a loop burning API credits early

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that change data, on a server that answers without a sign-in: create_connect_link

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • list_connections

    List the org's connected providers and status.

  • get_overview

    Cross-provider rollup: balance, burn rate, days-to-zero, month-to-date spend, projection, rate-limit headroom. Per provider, spend_basis says where month-to-date spend comes from: 'reported' (provider usage or itemized events) or…

  • get_provider

    Full metrics + rate-limit snapshots for one connection id. Includes spend_basis ('reported' | 'observed_since_connected'), observed_since and balance_scope ('account' | 'key' | 'unknown').

  • get_rate_limit_status

    Latest rate-limit headroom and error rate across the org's providers.

  • get_advisories

    All current advisories (top-up, upgrade, near-limit, spend-spike) across providers.

  • get_cost_accuracy

    Cost-accuracy state per provider: whether itemized costs are exact, estimated, or unreconciled, with the drift % between Argus's itemized total and the provider's own reported spend. 'unreconciled' means no provider anchor has been…

  • get_request_costs

    Recent itemized per-request costs for a provider (model, tokens, cost in USD, provenance). Args: provider (string), limit (number, default 25, max 100).

  • list_available_providers

    Providers that can be connected with an API key (poll plane). Anything else can still be tracked by sending telemetry — see https://argus.town/docs/ingest.

  • create_connect_link

    Hand a provider credential to Argus without it passing through you: returns a single-use URL (valid 1 hour) where your operator pastes the key. Show the URL to your operator, then poll get_connect_link for the connection id. Prefer this…

  • get_connect_link

    Status of a connect link: pending, submitting (the human is mid-submit), done (with connection_id), expired, or locked after repeated bad credentials.

  • connect_provider

    Connect a provider to THIS project with a credential. Validates the credential against the provider before storing it (encrypted), then queues the initial sync. Args: provider (id from list_available_providers), secret (the provider API…

  • sync_connection

    Queue an immediate balance/usage/plan refresh for one connection. Args: connection_id.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "argus": {
      "type": "http",
      "url": "https://api.argus.town/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http argus https://api.argus.town/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://api.argus.town/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
