Tokencost Dev vs Lm

A side-by-side look at the Tokencost Dev and Lm MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Verdict: choose Tokencost Dev for conversational ai work as a local process; choose Lm for conversational ai as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities

Tokencost Dev tools 4

  • get_model_detailsLook up pricing, context window, and capabilities for an LLM model. Uses fuzzy matching so you don't need the exact model key.
  • calculate_estimateEstimate the cost for a given number of input and output tokens on a specific model. Supports optional cached_tokens for prompt caching discounts.
  • compare_modelsFilter and compare models by provider, minimum context window, or mode. Returns top 5 most cost-effective matches.
  • refresh_pricesForce a re-fetch of pricing data from the LiteLLM registry. Use this if you suspect the cached data is stale.

Lm tools 8

  • chatThe workhorse. Send a task, get an answer. The description includes planning triggers that nudge Claude to identify offloadable work when it's starting a big task.
  • custom_promptThree-part prompt: system, context, instruction. Keeping them separate prevents context bleed - consistently outperforms stuffing everything into one message, especially with local models. I tested this properly one weekend - took the same batch of review tasks and ran them both ways. Splitting thi…
  • code_taskBuilt for code analysis. Pre-configured system prompt with temperature and output constraints tuned per model family via the routing layer.
  • code_task_filesLike `code_task`, but the local LLM reads files directly from disk — source never passes through the MCP client's context window. Use this when reviewing multiple related files, or a single large file that's awkward to paste. Files are read in parallel with `Promise.allSettled`, so one unreadable f…
  • embedGenerate text embeddings via the OpenAI-compatible `/v1/embeddings` endpoint. Requires an embedding model to be available - Nomic Embed is a solid choice. Returns the vector, dimension count, and usage stats.
  • discoverHealth check and speed readout. Returns model name, context window, capability profile, connection latency (labelled explicitly — this is the `/v1/models` fetch round-trip, *not* inference speed), and the active model's measured tok/s and TTFT averaged over the session. Before any real call has run…
  • list_modelsLists everything on the LLM server - loaded and downloaded - with full metadata: architecture, quantisation, context window, capabilities, and HuggingFace enrichment data. Shows capability profiles describing what each model is best at, so Claude can make informed delegation decisions.
  • statsCompact markdown dump of your offload stats — session and lifetime totals, per-model performance history, reasoning-token overhead — without the model catalog that `discover` prints. Cheap to call repeatedly to watch the 💰 counter climb.

Ready-to-paste client configs

Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

Frequently asked questions

Tokencost Dev is categorized under Conversational AI and uses a local stdio subprocess. Lm belongs to Conversational AI and uses a local stdio subprocess. Pick Tokencost Dev for conversational ai work and Lm for conversational ai.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Tokencost Dev has no declared pricing — check the project's own site. Lm has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add tokencost-dev and lm as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, Tokencost Dev has a quality signal of 60/100 (Good) with 1 views, 0 installs and 1 GitHub stars. Lm has 61/100 (Good) with 0 views, 0 installs and 121 GitHub stars.
