Installation

npm install -g @striderlabs/mcp-max

Or use directly with npx:

npx @striderlabs/mcp-max

Configuration

Add to your MCP client configuration (e.g., Claude Desktop claude_desktop_config.json):

{
  "mcpServers": {
    "max": {
      "command": "npx",
      "args": ["-y", "@striderlabs/mcp-max"]
    }
  }
}

Authentication

This connector uses browser automation. To use features that require authentication (watchlist, continue watching, viewing history), you'll need to be logged into Max in the browser session.

The browser runs in headless mode by default. For first-time login, you may need to modify the headless option to false temporarily to complete authentication.

Available Tools

5 tools
max_get_continue_watchingA

Get the list of content the user has started watching but hasn't finished, including progress information.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A4.5/5.0
Behavior5/5

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

No annotations provided, so description carries full burden. Clearly states the tool returns a list of incomplete content with progress information. No hidden side effects or safety concerns need disclosure.

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?

Single sentence conveying all necessary information without fluff. Front-loaded with the action and resource.

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?

For a simple zero-parameter tool with no output schema, the description adequately explains what the tool does and what it returns. No gaps identified.

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?

No parameters exist; schema coverage is 100%. Description adds context but is not needed for parameter understanding. Baseline score of 4 is appropriate.

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?

Clear verb 'Get' and specific resource 'content the user has started watching but hasn't finished, including progress information'. Differentiates from sibling tools like max_get_watchlist (saved content) and max_get_viewing_history (all history).

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?

Usage is implied by the purpose (unfinished content), but no explicit when-to-use or when-not-to-use guidance is provided. Sibling tools could be alternatives for other use cases, but this is not stated.

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

max_get_detailsA

Get detailed information about a specific movie or TV show on Max, including description, cast, rating, and more.

ParametersJSON Schema
NameRequiredDescriptionDefault
urlYesThe URL or path of the content (e.g., '/movies/the-dark-knight' or full URL)

TDQS

A3.8/5.0
Behavior3/5

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

With no annotations provided, the description carries the full burden. It indicates a read operation and lists returned data types, but lacks details on authentication needs, error handling, or other behavioral traits. No contradictions present.

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?

The description is a single, well-formed sentence that conveys the tool's purpose and output examples without unnecessary words. It is appropriately front-loaded and concise.

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?

Given the simplicity of the tool (single parameter, no output schema), the description covers the return fields adequately. However, it could be slightly more complete by specifying the output format or scope (e.g., full metadata).

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 parameter description already defines the 'url' field clearly. The tool description adds value by listing what information is returned, but does not provide additional semantic meaning 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?

The description clearly states that the tool gets detailed information about a movie or TV show on Max, listing example fields like description, cast, and rating. This specific verb+resource combination differentiates it from sibling tools like search or watchlist.

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?

The description implies usage for retrieving details of a specific content item, but it does not explicitly state when to use it versus alternatives like max_search or max_get_watchlist. No exclusions or context are provided.

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

max_get_viewing_historyA

Retrieve the user's complete viewing history on Max, showing previously watched content.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A3.7/5.0
Behavior3/5

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

With no annotations, the description carries the full burden of behavioral disclosure. It implies a read operation and describes the result as 'complete viewing history' and 'previously watched content', but does not disclose potential large data sizes, ordering, or any side effects. It is adequate but lacks depth beyond the basic function.

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?

The description is a single, efficient sentence with no unnecessary words. Every word contributes to the purpose.

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

Completeness3/5

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

Given no parameters, no output schema, and no annotations, the description provides the core purpose but lacks detail on output structure (e.g., format, fields) or any pagination. It is minimally complete but leaves the agent guessing about the return value.

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?

The tool has zero parameters and the schema description coverage is 100% (trivially). Baseline for 0 parameters is 4, and the description does not need to add parameter information.

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 verb 'Retrieve' and the resource 'user's complete viewing history on Max', with the additional context 'showing previously watched content'. This distinguishes it from sibling tools like max_get_watchlist (current watchlist) and max_get_continue_watching (in-progress items).

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

Usage Guidelines2/5

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

The description provides no guidance on when to use this tool versus alternatives (e.g., max_get_watchlist, max_get_continue_watching). It does not mention prerequisites, limitations, or when not to use it.

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

max_get_watchlistA

Retrieve the current user's watchlist (My Stuff) from Max. Requires the user to be logged in.

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

A4.2/5.0
Behavior3/5

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It correctly notes the tool is a retrieval (read operation) and requires authentication. However, it does not describe the output format or any limitations (e.g., pagination), which would be helpful.

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?

The description is a single sentence that conveys all necessary information without any wasted words. It is well-structured and front-loaded with the core action.

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?

Given no parameters and no output schema, the description covers the essential: what the tool does and a key requirement. It could be slightly improved by hinting at the return type (e.g., 'returns a list of items'), but for a simple retrieval, it is largely complete.

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?

The tool has no parameters, and the schema coverage is 100%. The baseline for 0 parameters is 4, as the description does not need to add parameter details. The description adds no parameter information, which is appropriate.

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 action ('Retrieve'), the resource ('watchlist (My Stuff)'), and the service ('from Max'). It distinguishes itself from sibling tools like max_get_continue_watching and max_get_viewing_history by specifying 'watchlist'.

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?

The description mentions a prerequisite ('Requires the user to be logged in.'), which helps the agent understand usage context. However, it does not explicitly state when to use this tool versus alternatives, though the tool's specificity makes this less critical.

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

TDQS

A4/5.0
Disambiguation5/5

Each tool targets a distinct aspect of Max: watchlist, continue watching, viewing history, search, and details. The descriptions clearly differentiate them, leaving no ambiguity.

Naming Consistency5/5

All tools follow a consistent pattern: 'max_' prefix + verb + noun in snake_case. Verbs are descriptive (get, search) and object names are clear.

Tool Count4/5

5 tools is a reasonable count for an info-retrieval-focused server. It covers the core read operations without being too sparse, though a few more could be added.

Completeness3/5

The set covers all main read operations (lists, search, details) but lacks any write operations (e.g., add/remove from watchlist), which limits completeness for full interaction.
