mcp-ollama
MCP server wrapping local Ollama models for offload from API-priced orchestrators. Nine stdio tools - generation, summarisation, analysis, drafting, code tasks (docstring/test/explain/review/types/refactor-suggest), diff-driven tasks (commit-message/pr-description/changelog/summary/impact), mechanical transforms, and model management (list/pull). Apache-2.0.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
local_generateGeneral-purpose local LLM generation. Delegates work to a local Ollama model to save tokens. Use this when the task is bulk text processing that doesn't require Opus-level reasoning: summarising documents, explaining code for docs, generating boilerplate, reformatting content, translating, etc. The…
local_summarizeSummarise long text locally. Use this instead of having Opus process large blocks of text when you only need a summary. Feed in file contents, docs, logs, or any bulk text and get a concise summary back. Particularly valuable for: large file contents, documentation, log output, meeting notes, long …
local_analyzeExtract structured information from text locally. Use this for classification, entity extraction, tagging, pattern recognition, or any task that transforms unstructured text into structured output. Good for: categorising issues, extracting names/dates/amounts, tagging content, parsing semi-structur…
local_draftDraft text locally - commit messages, PR descriptions, docstrings, changelog entries, documentation sections, or any formulaic text that follows a template or convention. Saves Opus tokens on boilerplate generation.
local_codeCode-aware local generation. Claude reads source code with Read/Grep (free), then delegates the TEXT GENERATION to local - docstrings, test stubs, explanations, type annotations, inline comments, or review feedback. This is the primary tool for reducing API token usage on code tasks. Claude orchest…
local_diffAnalyse a git diff locally. Use this for generating commit messages, PR descriptions, changelog entries, or understanding what changed in a diff. Claude runs `git diff` (free), passes the output here for text generation. Particularly valuable for large diffs that would consume many API tokens if pr…
local_transformPerform mechanical code transformations locally. These are pattern-based transforms that don't require architectural understanding - the kind of work that burns API tokens for no good reason. Use this for: converting between formats, renaming patterns, migrating syntax, generating boilerplate from …
local_modelsList all models available in the local Ollama instance. Use this to check what models are loaded and available for delegation.
local_pullPull/download a model into Ollama from the registry, or import a local GGUF file. Use this to make additional models available for delegation. For GGUF files, create an Ollama Modelfile first, then use 'ollama create'. This tool handles registry pulls (e.g., 'qwen2.5:14b', 'deepseek-r1:8b').
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
MCP_OLLAMA_ALLOW_REMOTEOLLAMA_HOSTOllama host: http://localhost:11434 (override via )OLLAMA_MODELDefault model: hermes3:8b (override via )Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
9/9 tools missing one or more hints — local_generate (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); local_summarize (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); local_analyze (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
5/9 tool handlers declare input schemas (56%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/9 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Domain consistency
npm scope @truealter doesn't match GitHub owner true-alter
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
