SlangLane MCP server

Which MCP servers are SlangLane's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is

Should an agent connect itConnect it
  • Its tools do every use case we checked: look up the meaning and tone of slang terms; decode a phrase by pasting it into a decoder.

Once connected

  • For "look up the meaning and tone of slang terms", the likely first call is lookup_term.
  • For "decode a phrase by pasting it into a decoder", the likely first call is decode_phrase.
  • Parameters are untyped or undescribed in 2 of 6 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Tools it offers6 tools · read 2026-10-28
  • lookup_term

    Look up an exact published slang term, slug, or alias. Includes sources, maturity, canonical URL, and ambiguity. Never generates a meaning.

  • search_terms

    Search published names, aliases, and summaries. No web search or generation.

  • decode_phrase

    Find documented slang in a phrase. Preserves ambiguity; not an interpretation of speaker intent. Text is sent to this reference server, never to an LLM.

  • compare_usage

    Return documented regional, register, and disambiguation notes for an exact term. Missing regional evidence is not invented.

  • get_related_terms

    Read published related terms for an exact term or alias.

  • get_recent_terms

    Get recent published dictionary summaries, with an optional adult-language filter.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
