PropelAuth Integration MCP Server

Migrate to PropelAuth Backend

migrate_to_propelauth_backend

Read-onlyIdempotent

Returns instructions for migrating to PropelAuth in a backend framework such as Express, FastAPI, Go, and more; Guidance includes migrating from either Clerk or Auth0. Each guidance will include documentation from the auth provider and PropelAuth. It is important to follow the instructions carefully to ensure a successful integration. It is important to call each guidance individually to ensure a successful integration. IMPORTANT: The backend_framework choice depends on the current auth provider implementation, not just the language. Select 'OAuth' if the backend currently handles the login flow using redirects (e.g., uses express-openid-connect or passport). Select any other option only if the current backend is a pure API that validates JWTs without managing the redirect-based login session. This excludes fullstack Next.js implementations.

A4.3/5.0

Behavior4/5

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

Annotations already indicate read-only, idempotent, and non-destructive behavior, and the description aligns with this. It adds behavioral context by stating that guidance must be called individually and that each includes documentation from both providers, which enriches the agent's understanding beyond annotations.

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

Conciseness3/5

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

The purpose is front-loaded, but the description contains redundancy with repeated 'It is important to' phrases and somewhat verbose warnings. The excessive emphasis on carefulness and individual calls could be condensed without losing value.

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?

The description covers parameter selection logic, provider sources, and invocation style reasonably well. It explicitly excludes fullstack Next.js implementations, which is useful context. Since an output schema exists, the lack of return format details is acceptable.

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

Parameters5/5

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

Despite 0% schema description coverage, the description compensates thoroughly. It explains the critical backend_framework parameter in depth (OAuth vs. pure API), clarifies migrating_from options, and implies the guidance parameter by mentioning 'each guidance' and the need for individual calls. All parameters gain meaningful semantics.

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?

The description clearly states the tool 'Returns instructions for migrating to PropelAuth in a backend framework' and specifies the source providers (Clerk or Auth0). It distinguishes itself from sibling integration tools by focusing on migration, and the backend framework scope is explicit.

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?

It provides detailed guidance on when to use the 'OAuth' backend_framework value versus other options, based on the current auth implementation. It also instructs the agent to 'call each guidance individually' for successful integration, though it does not explicitly compare against sibling migrate/integrate tools.

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