Flowlines - MCP Analytics

Get Flowlines onboarding plan

onboarding

Read-onlyIdempotent

Returns an instrumentation plan for an MCP server in the authenticated Flowlines namespace, based on the owner's saved setup choices. Use when the user requests help instrumenting their MCP server. Includes the span contract, field definitions, test cases, verification information, and a reference implementation for the selected language. If no choices are saved, returns needs_setup; use_defaults applies defaults to this plan only when the user chooses them. Does not edit source code, change namespace settings, create API keys, deploy software, or send test calls. Never include a Flowlines API key in tool inputs or chat.

Input Schema

`stack`	No	Programming language of the MCP server, used to select its reference implementation.
`reason`	Yes	A short phrase saying why you are calling this tool, for example: find unpaid invoices.
`user_intent`	Yes	One sentence describing what the user is trying to accomplish. Keep it the same across calls until the user's goal changes.
`namespace_id`	Yes	Flowlines namespace UUID.
`use_defaults`	No	Use default instrumentation choices for this plan when no saved choices exist. Set only when the user chooses to continue with defaults.

A4.4/5.0

Behavior5/5

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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, and the description still adds real behavior: the needs_setup fallback when no saved choices exist, the semantics of use_defaults being scoped to this plan only, and an explicit negative capability list. The security note about never passing an API key is additional operational context not encoded anywhere in the schema.

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-loaded with purpose and trigger before the capability and exclusion lists, and no sentence is obviously filler. Some clauses (needs_setup/use_defaults) are compressed into one long sentence, making it slightly dense but still readable.

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

Completeness5/5

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

Output schema exists, so return-value shape needn't be spelled out, and the description nonetheless covers the content of the plan, the empty-state behavior, and the safety boundary. For a read-only, closed-world plan generator with a fully documented schema, nothing an agent needs to call it correctly is missing.

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 parameters are already documented, and the description largely restates them ('reference implementation for the selected language' mirrors the stack field; the use_defaults caveat mirrors the schema text). Baseline 3 is appropriate since it adds no syntax or format detail beyond the schema.

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 ('Returns an instrumentation plan for an MCP server in the authenticated Flowlines namespace') and enumerates the payload: span contract, field definitions, test cases, verification info, and a language-specific reference implementation. This clearly separates it from siblings like check_onboarding (status) or get_mcp_recommendation, which an agent could otherwise confuse with it.

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?

Gives an explicit trigger ('Use when the user requests help instrumenting their MCP server') and a clear set of exclusions ('does not edit source code, change namespace settings, create API keys, deploy software, or send test calls'), which prevents misuse as a generic remediation tool. It stops short of naming a specific alternative to use instead when the user wants a status check or a recommendation.

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