openbot-mcp

openbot-mcp is the Model Context Protocol server for OpenBot.ai. It lets AI agents such as Claude Code, Cursor and Claude Desktop use OpenBot tools for physical AI data work.

Status: skeleton. PyPI has only the pre-release 0.1.0.dev0, published to reserve the name; pip install openbot-mcp does not select it. Only the server_status tool exists. Data audit, training readiness, Catalog and judgment tools are being designed.

Run from source

pip install -e ".[dev]"
OPENBOT_MCP_ROOTS=/path/to/data openbot-mcp

Claude Code:

claude mcp add openbot -e OPENBOT_MCP_ROOTS=/path/to/data -- openbot-mcp

Other MCP clients use the same command in their MCP configuration file:

{
  "mcpServers": {
    "openbot": {
      "command": "openbot-mcp",
      "env": { "OPENBOT_MCP_ROOTS": "/path/to/data" }
    }
  }
}

Configuration

Variable

Required

Description

OPENBOT_MCP_ROOTS

Yes, for local tools

Directories the server may read, separated by the OS path separator. Paths outside them, including symlinks that point outside, are rejected.

OPENBOT_MCP_OUTPUT_DIR

No

Where artifacts are written. Default ./openbot-output.

OPENBOT_BASE_URL

No

OpenBot API base URL. Default https://api.openbot.ai/v1.

OPENBOT_MCP_REDACT_PATHS

No

Default true: replace file paths with episode-relative ids in evidence sent to paid APIs.

OPENBOT_MCP_PAID_TOOLS

No

Default false: paid tools stay hidden until they are available.

Data boundary

Local tools only read the directories in OPENBOT_MCP_ROOTS and only write to the output directory. The server never modifies source data, never runs shell commands and collects no telemetry.

Development

pip install -e ".[dev]"
python scripts/check_version.py
pytest -v
ruff check src tests scripts
mypy src
python -m build

VERSION is the package version source of truth. To release, update VERSION and CHANGELOG.md, verify locally, then publish a GitHub Release whose tag is v<version>. The release workflow tests every supported Python, builds the distributions and publishes to PyPI through a trusted publisher.

Package boundaries

  • openbot-mcp: MCP server for AI agents.

  • openbot-data: local robot/ego data processing library.

  • openbot-sdk: OpenBot platform API client.

TDQS

A4.3/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds a useful scoping detail ('which local directories it may read'), but it does not disclose any other behavioral aspects like potential network calls, authentication requirements, or response format specifics. Given the low bar set by annotations, this is adequate but not outstanding.

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, front-loaded sentence with no filler. Every word contributes to explaining the tool's function. It is maximally concise while remaining informative.

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?

The tool is simple with no parameters and an output schema, so return values are already covered. The description covers the essential information an agent needs to decide to call it and what to expect. Nothing critical is missing for a status-reporting tool.

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 schema coverage is 100% (vacuously). Per the rubric, with no parameters the baseline is 4. The description does not need to add parameter details, and it doesn't, so a 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?

The description states a specific verb ('Report') and resource ('OpenBot MCP server version' and 'local directories it may read'). It is precise and unambiguous, and there are no sibling tools to differentiate from, so it fully establishes what the tool does.

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 implies when to use it: whenever you need server version or directory access info. Since there are no alternatives or siblings, it doesn't need to explicitly route away from other tools. The clarity of purpose makes the usage obvious, though it doesn't spell out any conditions or exclusions.

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

Disambiguation5/5

Only a single tool exists, so there is no possibility of confusion between tools. The tool's purpose is clear and distinct.

Naming Consistency5/5

With only one tool, naming is trivially consistent. The name follows a clean noun_noun pattern with no conflicting conventions.

Tool Count1/5

A single trivial status tool is far too few for an MCP server that presumably should provide meaningful bot-related functionality. This is an extreme mismatch.

Completeness1/5

The server only exposes a status/version endpoint and does not provide any actual operations, data access, or workflow coverage. The surface is severely incomplete for any plausible domain.
