Spala Public MCP

Connect Spala Project

project_connect

DestructiveIdempotent

AUTH REQUIRED; IDEMPOTENT PROJECT CONNECTION WRITE. Prepares one accessible Spala project for agent access. Accepts one installer client (codex, roo, claude-code, cursor, a2a); when omitted, returns a client-selection response without executable arguments. Pending projects return project_provisioning with status 202 and retryAfterSeconds; retry the same call within the stated budget. Active projects do not need a manifest before connect. Returns a client-specific workspace binding plan: protected one-time bootstrap for Codex, Roo, and Cursor; verifier-bound delegated bootstrap for Claude Code.

A3.9/5.0

Behavior5/5

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

Goes well beyond the annotations: it discloses AUTH REQUIRED, the 202 project_provisioning response with retryAfterSeconds and retry budget, that active projects need no manifest, and the client-specific binding plans (one-time bootstrap vs verifier-bound delegated bootstrap). This is rich operational context for a mutating, idempotent, open-world tool.

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

Conciseness4/5

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

Front-loads the two most important facts (AUTH REQUIRED; IDEMPOTENT WRITE) and then flows logically through client selection, pending/active states, and return shape. Dense but mostly earns its sentences, though phrasing like 'without executable arguments' is slightly opaque.

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 complex, authenticated mutation with a full output schema, the description still covers auth, idempotency, retry timing, and per-client binding behavior. The only gap is that it does not restate the mutually-exclusive project selector requirement, which the schema handles.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents every parameter, including the oneOf projectId/subdomain split and the bootstrap fields. The description adds only the client-omission response behavior, which the schema also states, so it does not materially extend schema meaning.

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

Purpose4/5

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

States a specific verb and resource: 'Prepares one accessible Spala project for agent access', distinguishing it from creation ('accessible' implies the project already exists). It is clear what the tool does, but it never names siblings like project_create or project_select to sharpen the boundary.

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

Usage Guidelines3/5

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

It gives useful context about pending vs active projects and the client-omission path, which shapes when the call succeeds, but it never says when to choose this over siblings such as project_select, project_create, or spala_start. Usage is implied rather than compared against alternatives.

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