At a Glance & Executive Verdict
AgentPhone
Developer Tools · Local stdio
Quality: 49/100 (Fair) | Auth: No auth required
Cactus
Developer Tools · Remote HTTP/SSE
Quality: 48/100 (Fair) | Auth: No auth required
Verdict Summary: Choose AgentPhone if you need specialized Developer Tools tools running via a local process. Choose Cactus if your workspace requires Developer Tools integration with remote web transport. Both servers can be configured concurrently in your client's mcpServers manifest.

Cactus Tools (2)
resolve
NCI CACTUS chemical identifier resolver. Convert one chemical identifier (a drug/chemical name, CAS number, SMILES, InChI, or InChIKey) into a single representation: smiles (canonical SMILES), stdinchi (standard InChI), stdinchikey (standard InChIKey), iupac_name, names (synonym list), formula (mol…
identify
NCI CACTUS one-shot lookup: given any chemical identifier (name, CAS, SMILES, InChI, or InChIKey), return SMILES, InChIKey, IUPAC name, molecular formula, molecular weight, and CAS number in a single call. Fields that cannot be resolved are returned as null. Keyless, plain-text API.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
AgentPhone is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Cactus belongs to Developer Tools using remote streaming HTTP/SSE transport. Select AgentPhone when you need capabilities focused on developer tools and Cactus when you require tools for developer tools.
