What can you do with this server?

It is an MCP server that gives agents a searchable, executable vocabulary of typed mathematical operations. * math.find: search for operations by describing a mathematical need, optionally filtering by namespace and paging; inspect an exact operation_id to get schemas, examples, and backend availability. * math.run: execute one operation by ID with a typed payload and receive its canonical mathematical result. * Compose results: pass one operation's output as input to a later operation. * Covers polynomial algebra, exact linear algebra, graphs/paths/colorings/isomorphism, bounded SAT/SMT, finite algebra, probability, geometry, and topology. * Results are exact where claimed, with approximation, incompleteness, or uncertainty made explicit. * Checks optional Singular/QEPCAD backend availability and reports runtime requirements. * The same mathematical library is also available through a CLI and native Python API.

How do I use jacobian?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@jacobian find a counterexample to the claim that f(x)=x^2 is injective" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Jacobian is an MCP server that gives AI agents a searchable vocabulary of typed mathematical operations. math.find matches a mathematical need or inspects one exact contract, and math.run executes it and returns its typed result. The same mathematical library is also available through a CLI and native Python API.

Each operation establishes one stable, reusable mathematical postcondition rather than prescribing a workflow or proof strategy. Results are exact where claimed and make approximation, incompleteness, or uncertainty explicit.

Jacobian's hypothesis is that mathematical reasoning benefits from an executable vocabulary of semantically scoped, bounded operations. Rather than exposing large domain solvers or precomposed workflows, Jacobian exposes mathematical primitives that agents can search for and compose into solutions beyond what any individual operation was designed to solve. The library supplies trustworthy mathematical moves; the reasoning model decides which moves to make, how to combine their results, and when to stop. Keeping the operations semantically narrow and domain-owned preserves that search space instead of baking one proof strategy or workflow into the tools themselves.

See Executable mathematical vocabulary for what semantic atomicity means and how the operation vocabulary grows.

Quickstart

Set up Jacobian for your agents with a single command. The setup command requires Node.js 20.17+, 22.13+, or 23.5+ and uvx on your PATH.

npx jacobian@latest setup

Choose detected agents and review the changes before they are written. Setup does not install Node.js, Python, uv, or an agent. For automation, preview an explicit plan with npx jacobian@latest setup --codex --dry-run; use --yes only with explicit agent flags or --all.

To refresh an existing registration explicitly, run npx jacobian@latest upgrade and select the agents to update. The generated launcher pins the exact release resolved by npm.

Run the canonical Python MCP command without installing Jacobian globally:

uvx --from jacobian jacobian-mcp

Where an MCP host requires an npm command, the npm package is a deterministic carrier for that same command:

npx jacobian mcp

For a persistent installation:

python -m pip install jacobian
jacobian-mcp

That package includes Jacobian's exact maintained Python backend stack: SymPy, NetworkX, Z3, and Python-FLINT. A normal Python or npm installation therefore exposes the same built-in Python-backed operation portfolio. The tested binary-install contract is CPython 3.12 or 3.13 on glibc Linux x86-64; the release gate installs the built wheel and starts Jacobian on both Python versions. Other systems may have compatible upstream wheels, but are not part of the tested release contract yet. In particular, Alpine/musl cannot install the complete mandatory stack from PyPI.

Singular and QEPCAD are optional system runtimes for a small subset of operations. The Python installation does not provision them, and ordinary operations do not require Docker. Python callers can use jacobian.backends.check_backend; MCP inspection reports availability in the server environment. See backend requirements for exact coverage and setup.

The Python distribution contains the mathematical kernel, CLI, and MCP server. The npm package deterministically maps its exact package version to the corresponding uvx invocation.

Related MCP server: math-logic-mcp

Compute one bounded result

An ordinary operation returns mathematics first. For example, matrix.determinant.compute accepts one exact rational matrix and returns its determinant directly. Callers compose results by passing their typed values to a subsequent operation.

For a local terminal workflow, inspect the exact installed contract and run one of its examples with the CLI:

jacobian inspect integer.compute.extended_gcd
jacobian run integer.compute.extended_gcd --json '{"left":"84","right":"30"}'

The second command returns the gcd and Bézout coefficients as JSON. In an MCP host, use math.find in inspection mode to read the same contract and math.run with the same payload shape. See Discover and invoke operations for that agent workflow.

Available mathematics

The built-in portfolio covers work in:

polynomial maps and polynomial algebra;
exact linear algebra;
graphs, paths, colorings, and isomorphism;
bounded SAT and SMT solving;
finite algebra, probability, geometry, and topology.

SAT and SMT operations use the maintained Z3 Python binding directly. Use math.find to match the mathematical result needed, then use its inspection mode on a promising operation before calling math.run once.

See the domain operation library for the maintained operation portfolio and backend requirements.

Status

Jacobian 0.21.0 is pre-stable. Its published package and operation contracts describe the supported surface; experimental operation contracts may change between releases.

Available Tools

2 tools

math.findSearch installed Jacobian math toolsA

Read-onlyIdempotent

Find or inspect public Jacobian MCP operations.

Forms:

query: describe one local mathematical need in ordinary language. namespace, limit, and cursor are optional search controls. Preserve established mathematical names from the task, the supplied objects and constraints, the requested computation or decision, the full scalar, batch, or exhaustive scope, and whether the requested result is a value, witness, certificate, obstruction, profile, or complete enumeration. Do not replace a supplied named property only with its expanded definition, translate the need into catalog tags, or submit the surrounding proof goal.
operation_id: pass one exact operation ID to receive its authoritative input and output schemas, operator-authored examples, and current optional backend availability. Matches expose static runtime_requirements; inspection checks these runtimes in the server environment.

For matching, use namespace only when the primary operation-ID namespace is already known with high confidence. Matching returns 10 candidates by default; request up to 20 when a wider first page is useful. Follow next_cursor with the same need and namespace to continue. Ordered matches are deterministic retrieval candidates, not applicability claims; inspect a promising operation before math.run. Read operation://catalog only when the complete bulk catalog is genuinely needed.

Examples:

{"query":"exact determinant of a rational matrix","namespace":"matrix","limit":3}
{"operation_id":"polynomial.compute.gcd"}

ParametersJSON Schema

Name	Required	Description	Default
`limit`	No
`query`	No
`cursor`	No	Opaque continuation cursor from a prior call with the same need and namespace. The page limit may change between calls.
`namespace`	No	Optional exact primary operation-ID namespace. Omit it unless already known with high confidence.
`search_mode`	No	Precise applicability filtering or broad lexical recall.	precise

A4.5/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds value beyond these: ordered matches are deterministic retrieval candidates not applicability claims, matching returns 10 candidates by default (up to 20), matches expose static runtime_requirements while inspection checks runtimes in the server environment. This is meaningful behavioral context that annotations alone do not convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long but information-dense with no wasted sentences. It is well-structured into Forms, matching semantics, pagination, and Examples sections, and front-loads the purpose before usage nuance. Every sentence earns its place, though it could be trimmed slightly without losing value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need no explanation. The description comprehensively covers both call forms, pagination behavior, matching semantics, namespace usage, catalog access, and the relationship to math.run. The only minor gap is search_mode, which is not described beyond its schema enum text.

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?

With 50% schema coverage, the description carries substantial parameter meaning: it explains what to preserve in query (names, objects, constraints, scope, result type) and what to avoid, defines operation_id's return (schemas, examples, backend availability), clarifies limit defaults (10, up to 20), and gives namespace and cursor usage rules. Only search_mode lacks description-level explanation, though its schema enum description ('Precise applicability filtering or broad lexical recall') covers it.

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?

States a specific verb-resource pair ('Find or inspect public Jacobian MCP operations') and enumerates two distinct forms (query search vs operation_id inspection). The description differentiates it from sibling math.run by explicitly routing inspection before math.run execution.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit when-to-use guidance: use namespace only when the operation-ID namespace is known with high confidence, follow next_cursor with the same need and namespace, read operation://catalog only when the bulk catalog is genuinely needed, and inspect a promising operation before math.run. Names the alternative tool and the condition selecting it.

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

math.runRun one installed Jacobian math toolA

Read-only

Run one installed math tool by ID with its typed payload. A successful call returns the operation-owned canonical mathematical value in output; a later inspected operation may accept that complete value unchanged. Read its fields to determine what the calculation established. MCP reports malformed payloads, unknown IDs, and host failures as tool errors, not as mathematical results. If the payload shape is unknown, inspect the exact operation with math.find. When it publishes an examples item, copy and adapt that item's input object as the payload; otherwise, form the payload from the input schema and its field descriptions. Do not call math.run with an empty payload merely to discover required fields; inspection is authoritative.

Timeout, incomplete search, and missing witnesses appear only in the concrete domain result that owns them; none is a mathematical conclusion by itself.

Examples:

{"operation_id":"integer.compute.extended_gcd","payload":{"left":"84","right":"30"}}

TDQS

A4.9/5.0

Behavior5/5

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

Beyond the annotations, the description explains that successful calls return a canonical operation-owned value, that malformed payloads, unknown IDs, and host failures surface as MCP errors, and that timeout/incomplete-search/missing-witness findings are not mathematical conclusions. This is meaningful behavioral context not present in the annotations.

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 front-loaded with the core action and then adds only high-value operational guidance: error semantics, discovery workflow, and an example. Every sentence earns its place despite the length, which is justified for a generic runner tool.

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?

For a generic runner with two parameters, an output schema, and a single sibling, the description fully covers invocation, payload discovery, error behavior, and result semantics. There are no significant gaps that would prevent an agent from selecting or using the tool correctly.

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?

Schema coverage is 0%, so the description carries the burden. It clarifies operation_id as a math tool ID and payload as the typed argument object, and gives a concrete example. It could enumerate more about operation_id format, but the schema pattern already covers that, and the discovery workflow is explicitly documented.

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 and resource: 'Run one installed math tool by ID with its typed `payload`' and clarifies the operation's return semantics. It differentiates from the sibling math.find by explicitly directing payload-shape discovery to math.find rather than math.run.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives concrete when-to-use guidance, including using math.find when the payload shape is unknown, adapting published examples, and avoiding empty-payload discovery calls. It also tells the agent that inspection is authoritative, which prevents misuse.

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

TDQS

A4.7/5.0

Scored 2026-09-15 17:40 across 2 tools

Disambiguation5/5

math.find is exclusively for discovery and inspection (search, exact operation lookup, schemas, examples), while math.run is solely for execution. There is no functional overlap or plausible confusion between the two tools.

Naming Consistency5/5

Both tools follow the same namespace.verb convention: math.find and math.run. The pattern is simple, predictable, and consistently applied across the entire tool set.

Tool Count4/5

Two tools is a small count, but it fits the server's two-stage purpose: discover/inspect operations, then run them. Each tool carries meaningful scope, so the count feels lean rather than deficient.

Completeness5/5

The tool surface fully covers the domain: math.find handles searching, exact lookup, bulk catalog access, and operation inspection, while math.run executes operations with typed payloads. No important lifecycle stage or obvious dead end is missing.
