dspace_login

Authenticate with a DSpace repository using a JWT token or username and password, then keep the session active for subsequent repository tool calls.

Instructions

Authenticate with a DSpace instance. Provide EITHER a JWT token directly, OR username + password for password-based login. The session persists for subsequent tool calls.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "dspace_login"
  }
}

passwordNoPassword for password login

TDQS

A4.2/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden. It usefully discloses that the session persists across subsequent tool calls, but says nothing about token lifetime, what happens on failure, whether credentials are stored, or how to re-authenticate after expiry.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, zero filler, with the core purpose front-loaded and the two login modes immediately following. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 3-param tool with no output schema and no annotations, the description covers the essentials: purpose, the two modes, and session persistence. Missing failure/expiry behavior keeps it short of a 5, but nothing critical blocks correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, and the description adds meaning beyond the schema by stating the either/or constraint: token OR email+password. That mutual exclusivity is not expressible in the flat schema and is the key semantic an agent needs.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Authenticate with a DSpace instance') and is clearly distinguishable from siblings like dspace_auth_status and dspace_logout. An agent can immediately tell this establishes a session rather than checking or ending one.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly lays out the two mutually exclusive entry paths (JWT token OR username+password), which is real usage guidance for how to call it. It does not, however, say when to prefer this over dspace_auth_status or when to call it again if a session already exists.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
